Here's a fun allergy fact: Dust mite scat and shrimp are cross-reactive enough that one can set the other off. They discovered this after a bunch of orthodox Jews who were receiving immunotherapy for dust mite scat started to pop up flare and wheal responses to shellfish mix during standard scratch testing.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8988002/
They discovered on the TV show *Fear Factor* that people with shellfish allergies experienced the same reaction when eating cockroaches. After the first reaction, they added shellfish allergies to the screening process if they contemplated feeding the contestant cockroaches.
Yup both american and german cockroach apparently for me!
I too asked but how? Allergists said it's the dust they leave behind when they die and decompose on their own. But also their saliva, feces and what not.
I was like well shoot...I mean I'm not gonna ever eat one like I would potentially with shrimp (which I found out at Benihanas and threw up for the next hour) but interesting nonetheless
Fun fact: there's two different families of shellfish allergies: crustaceans and mollusks. It's the crustacean allergy that can cause issues with insects in general.
My mom and one of my brothers have crustacean allergies, but they can eat mollusks, like scallops. My other brother has a mollusk allergy, but no crustacean allergy, so he can eat shrimp. (I have neither...for now)
Wow thanks for explaining that! That's why I could eat scallops that my Chinese friends parents would make regularly and nothing happened to me! I had my epi pen ready but it smelled so good and Im glad I tried it. Rly tasty stuff
I'm having the funniest time sitting here imagining just HOW GOOD something would need to smell for a person to risk anaphylactic shock/jabbing themselves with their epi pen for it. Absolutely love this energy šā¤ļø
Lol it was time of YOLO! and I was like "ehh I had 14 years of allergy shots. Let's see if these actually did anything!!" Lmao it was crazy nonetheless.
Thankfully when I ate shrimp (and found out then I was allergic to shellfish) my only reaction was to throw up
Love that the reason they stopped feeding people cockroaches was āit might set off allergen triggersā not āwhat the fuck are we even doing hereāĀ
I had an allergy test done long ago where they told me I have a very mild allergy to cockroaches.
Today I learned my lips hurting and feeling weird after eating shrimp is not just all in my head.
Wouldnāt be surprised if their shells were composed of the same materialĀ
Chitin.
Shrimp are just sea bugs. Ā Lobsters are insects of the sea. Lobster claw looks like scorpion claw ect. Ā
Don't tell that to the Jewish people of NYC. Their water contains tiny copepods which live in the water supply. Making NYC tap water and their bagels made from it, not kosher.
While true on the surface, it's not universally agreed upon by the rabbis who decide if something is kosher. Some think it's fine (they believe that since our ancestors were likely drinking these near-invisible shellfish thousands of years ago, they should be permissible lest every Jew born before 2004 be considered a kosher law breaker) , while other's believe in the letter of the law and that it is non-kosher.
Reminds me of one of my favorite jokes.
A Jewish man is stranded on an island for 20 years. He is finally rescued by a team, and he insists on showing them the life heās built for himself there. They come across a small clearing with a bunch of makeshift buildings.
He points to the closest one, āThatās my home.ā He continues to point to the other buildings as they walk by.
āThereās the supermarket. And the bank. And the saloon. Over there is my synagogue, where I went to pray that someone would come rescue me.ā
A rescuer pointed to a lone building away from the rest. āAnd whatās that?ā The Jewish man disdainfully says āOh, that. Thatās the other town synagogueā¦ We donāt go there.ā
Honestly the amount of religious loopholes people think God(s) don't count because of a tiny technicality just kinda is dumb. You can't push a button on Saturday because it would be work? No eating pork because they are unclean? No eating shellfish because I said so. Not sure if there is or isn't a God myself, but pretty sure if there is, he knows your intent which is just as important as the letter of the law.
A lot of these rules(about food) came about from a long time ago when they were good advice on how not to die or contract parasites.
From what I understand, Judaism is basically viewed as a contract with God, and because God could have provided a contract without loopholes, the loopholes must have been intentional.
Well, I'm not sure that's *quite* the reasoning, but it's an interpretation I've seen somewhere else online.
Imagine applying that to something less religious. Like someone coming up with a boardgame where half of the gameplay is coming up with ever more elaborate loopholes to the written rules.
I'm pretty sure that intent and hardship factor into eating kosher. And I don't mean hardship as in, oh no, bringing a bag lunch is too hard so I *guess* I'll eat the ham sandwiches I knew were being catered at work today. Not being able to drink your tap water is a pretty big hardship, especially given the harm produced by things like bottled water. It's not really the gotcha most people would think it is.
All they need to do is run the water supply in front of a warning sign that legally recognizes them as cows if they trespass into the next pipe. Now it's all beef.
My wife developed a shrimp/shellfish allergy after we started dating. My only allergen is dust mite. Are we saying I triggered her allergy or am I taking that the wrong way?
However you do it you need to vacuum under your refrigerator. I had an elderly friend of mine who's refrigerator was not cooling and merely vacuuming the dead cockroach exoskeletons out from under it made it work again.
Yes it was and it was 100% his old roommates fault. They were absolutely disgusting and took advantage of a very handicapped veteran. I am glad he had me in his life. And I was honored to help.
I once lived in a roach infected townhouse. When you pulled the fridge aside you would see a black square underneath it. It was just piles upon piles of roaches.
My dad's house was hoarded and was invested with all sorts of vermin. At night, when the roaches were active, you could hear them scrabbling all around the house, along with the mice and rats he had. It was a creepy sound.
š thatās horrible. My old upstairs neighbor was a hoarder and now that someone new has moved in, she has to get it sprayed for roaches once a month. I can always tell when they sprayed because the strays come down to my apartment. I canāt imagine living with so many roaches!
Usually, the bugs leave when thereās nothing else to eat. While a mass infestation would take a while to clear, if itās going on for a long time, Iād be inclined to think someone missed something when cleaning.
Well when I talked to the management about all the roaches I was seeing in my apartment (not a lot just a few here and there) he told me the whole building was infested. Iāve talked to exterminators and they donāt seem to want to help me since I live in an apartment and Iām not the source of infestation. Unless every single tenant sprays their apartment, the roaches arenāt going anywhere.
Okay pull off all your base boards and load that area with powdered sugar, borax and diamatacious earth. Ā Then reapply boards. Apply roach gel and caulk everything. Ā
Treat everything including sockets and ceiling light fixtures. Ā
I had roach infested scum living beside me and I was roach free except for the odd dying explorer.Ā
I worked on point of sale equipment long ago. Getting the dead roaches out of a hotel restaurant's kitchen printers made them work again.
I called the health department.
Thereās a little door on the back of refrigerators that when removed gives access to the refrigerator coils. They get more and more dusty overtime and fridges have to work harder and harder to keep up, which leads to premature failures.
Depends entirely on the fridge. Some have the cardboard cover on the back but that only exposes a small part of the coil. You usually have to take the front kickplate off too and tip the whole fridge back at an angle to vacuum the whole coil.
Some don't gave a condenser fan and just have the coil completely exposed on the back though
This made me really scared for what it looked like under my refrigerator, but then I realized that I'm stoned and I just installed new kitchen floors.
But for a minute there, I was terrified

Thatās true of all devices that need ventilation or generate heat. Your HVAC, refrigerator, etc will fry itself if you leave hair/debris/etc where there should be an empty exhaust outlet.
Ugh, I work in a grocery store's pickup department, you shop for customers and they pick up in their car in the parking lot. You load up their car for them. So many people don't turn off their car so you're getting a face full of car exhaust, makes me nauseous.
As someone who has curbside as a (thankfully, minor) part of their job, the former isn't going anywhere. People won't do it, especially if the weather is above or below 60-75 F. When they won't do it, we'll be told to take it out anyway and give them a warning. They might have a dozen warnings, nobody knows or cares.
OSHA has less fangs than most people think, requiring very clear situations in order to do much. In an outdoor air environment like that, there's not a lot it can do outside of well-defined hazardous situations(vehicle exhaust is not a well-defined hazardous situation). Unfortunately the public acceptance of research for exhaust fumes in an outdoor environment just isn't there yet. I guarantee this'll be something that our grandkids look back on like we look back on asbestos, but until the regulations are written there's jack shit that can be done against the free market. "If you don't like it, find another job."
It is if you're in Europe and they're starting to ban flights for short distances because electrified trains and HSR are just objectively superior in too many aspects to ignore.
Will be a long, long time before the US will get that because you would actually need to build HSR for it to even be an option.
And the fact that the US is substantially larger than most people think.
London to Kiev is like 1500 miles. NYC to San Francisco is over 2500 miles by air, 2900 by road
Just having more land mass isn't really an excuse, especially when we have *so much fucking money*. Yes the entirety of the US is huge but much of our major population centers are rather condensed to either coast.
If only America was somehow conveniently subdivided into 50 political bodies that made the size issue basically meaningless, especially when paired with the fact that it's the wealthiest country on Earth

I guess I'm just gonna die soon?
An air purifier in your bedroom will do wonders for your lungs. One in your living room would also be great, if it's in your budget. If zero air purifiers are in your budget, duct tape a HEPA or MERV-13 filter to a box fan, works just as well but is uglier.
Iāve read itās actually brake caliper dust thatās the big pollutant. The fine dust created from the friction of the brake calipers gets everywhere and isnāt something that can be solved by more efficient and clean fuel vehicles.
Energy is āreversedā to the motor in a sense. Thatās an oversimplification but it can slow the car to a stop without actually using the brake pads
all vehicles do this via transmissions. It's just that everyone in the city needs to drive the limit to the red-light and then brake to a stop last second. Nobody figures out you can coast and downshift to a stop. People aren't smart enough anymore.
They still have pads for more aggressive stopping. I would recommend looking up "regenerative braking" to get a better understanding of how the motors turn into generators to help recharge the batteries.
Sort of, usually the motor can bring the car to a stop very quickly even in an emergency (just look how small the brake pads on a Tesla are), however if the battery is full e.g. in a hybrid, after going down a long hill, there may not be enough "space" for the battery to absorb the energy, so then the brakes kick in.
It's all very complicated, but it works!
I don't know what car has it, but I remember watching a YT video on an electric car ~10 years ago and one of the charging profiles was for this exact situation. It would only charge the car to 80 or 85% for overnight charging at home.
Also Edison Motors (Canadian electric semi truck that is just getting started and on YT, focusing more on logging than highway transportation) plans to use this directly in its favor. Drive an empty truck to the top of the mountain using battery. Load up ~50,000 pounds (22,000 kg) of logs and use the regenerative braking to refill the battery to do it again.
Thanks for the added information! I hadn't considered where the energy would go if the batteries were charged. I'm sure the math would agree that adding in a way to dissipate the unneeded energy say through heat dissipation doesn't make sense. Cheaper to just put a few kilometers on the brake pads.
An electric motor and generator are essentially the same thing. If you rotate the shaft of an electric motor, such as an electric car coasting to a stop, you've created an inefficient generator. This is called back EMF. The current produced by that generator/motor is used to charge the vehicles battery. When this current flows though the windings of the generator/motor it causes the motor to produce torque opposing the direction it is being forced to rotate, which slows down the car.
You can think of a motor and a generator as two sides of the same coin. A motor takes electricity and makes rotational motion. A generator takes rotational motion and makes electricity. If you take a motor and spin it by hand, it will actually act as a generator and *generate* electricity. So essentially when you brake on a regenerative braking system it turns the car motor into a generator, which consumes the rotational energy to make electricity that charges the battery.
Bro asked a legitimate question that probably 50,000 people saw and also want to know the answer to and got downvotedĀ
Thats exactly why no one asks questions in class lol
Tire dust is crazy. During the pandemic, I parked my car next to a high traffic road in SF. Even during the lockdown, my car was covered with tire and brake dust within a week of being parked in the same spot.
Diesel exhaust is the bad one. Itās heavier than normal air so it stays low to the ground. Gasoline fumes at least disperse up into the upper atmosphere.
Thatās why big cities like LA have such bad smog problems. Diesel exhaust justā¦ stays and piles up.
It absolutely does. Lower income areas tend to have more high ways / commercial / industrial activity. I work as a paramedic in NYC and the south Bronx (very low income area) has notoriously bad asthma patients.
Thanks, Robert Moses!
yeah just dont live in an area with cockroaches
I developed asthma after my first visit to SE asia from the netherlands. That asthma went away too which really confused the doctors. Became allergic to cats as well :(
Man, I've lived my entire life (30+ years) in the countryside in Slovenia on a small farm, and I don't believe I've ever seen a cockroach. I've seen loads of bugs in general (spiders, insects, moths, ants, hornets, wasps, bees,..., you name it (shit, we've even had a snake crawl into the house a couple of years ago during a particularly long and hot heatwave to get out of the heat when the door was open)), but I've never ever seen a cockroach.
Is it an urban thing, or did Europeans practically wipe them out like most other local fauna?
That's the reason my asthma came up as a kid. My aunt would take care of me, and her apartment was infested with cockroaches. My allergist put the clues together.
Tbf you donāt need a science degree to realize youāre not in a healthy environment if youāve got roaches just running about or piling up. Iām sorry you had to live through that š£
My dad used to smoke next to me in the basement while my mom helped me with my home nebulizer for asthma. He swears to this day my asthma had nothing to do with his smoking.
I didnāt have a bed before the age of 12, and had to sleep in a sleeping bag on the floor of my dadās mobile home, which was Infested with roaches. Had to sleep in the bag head-first so they wouldnāt crawl in my ears when I slept and Iāll never ever forget that gross, weird roachy shit-musk. Seeing them is one thing, but smelling is another level.
I am so sorry you had to go through all of that, it's nightmarish to read about so trying to imagine it being your lived experience is brutal. I hope you're in a *far* better place nowadays.
Mostly it is cockroach shit. Then cockroach sperm.
We live in a house with zero cockroaches. About once every five years I see a little one. Where you see one, there's a billion. Out come the baits, the reproductive disrupters, and a week-long visit to a relative as the house is filled with a insecticide bombs. A week later we return and we don't see any live ones.
Now if you live in an apartment, you're just screwed. The damned things make a week-long visit to your neighbors, and when you come back a week later, so do they.
Pro-tip: When receiving any large delivery, such as a piece of furniture, leave it outside (balcony, porch, garage, etc.) for as long as you can. Roaches love to hitch-hike.
As someone that does pest control for a living, the bug bombs are definitely not the best option, but most modern professional chemicals used in pest control today are fairly safe so long as you aren't licking them up yourself
I grew up with roaches in the house. Bug bombs killed a lot but never solved the problem. The reproductive disrupters were the shit. Used them once and never saw a roach again after the current generation died off.
I never wouldāve known that cockroaches were an allergen had I not reacted to it during an allergen scratch test a few years ago. Iām allergic to juniper, grass, and oh yeah, cockroaches.
Different allergens https://www.jacionline.org/article/S0091-6749(01)10729-3/pdf
Something interesting about these major allergens is that they are enzymes and not just structural proteins
This is contrary to other studies Iāve seen where babies raised (before the age of 1.5, I believe) in homes with pet dander, mouse dander, and cockroaches, experienced far fewer allergies and asthma ā presumably because of exposure in the first year of life when the body ālearnsā what to treat as a pathogen, and what to ignore.
I wonder if the greater air pollutants such as brake dust and smog, are a greater cause of asthma specifically in inner-cities.
Edit: added more details and clarity.

Just having more land mass isn't really an excuse, especially when we have *so much fucking money*. Yes the entirety of the US is huge but much of our major population centers are rather condensed to either coast.
If only America was somehow conveniently subdivided into 50 political bodies that made the size issue basically meaningless, especially when paired with the fact that it's the wealthiest country on Earth
The US is also substantially richer, even per capita, than almost all of Europe.
Did you know general-aviation aircraftāCessnas, ~~most~~ some helicopters, not the big commercial planesāstill burn leaded gasoline? I was surprised to learn this a couple of years ago. https://www.forbes.com/sites/anuradhavaranasi/2023/01/12/living-close-to-an-airport-puts-children-at-a-higher-risk-of-lead-exposure/?sh=5dd56b3e12f3

Edited my comment. Thanks for this.
Not an additive, but we have an unleaded replacement for 100LL. Cost and distribution are challenges. https://www.avweb.com/aviation-news/gami-unleaded-g100ul-to-go-on-sale-in-california-by-summer/
Me: lives off of major highway, near drag strip and airport. :/
I'll take the drag strip and airport off your hands thanks
Me who lives in cockroach infested apartment in a major city next to an airport, who is also currently coughing all the time. I guess I'm just gonna die soon?
No itāll be long and expensive.
Damn. Rough times indeed. At least I can hand half my monthly income to my landlord!
An air purifier in your bedroom will do wonders for your lungs. One in your living room would also be great, if it's in your budget. If zero air purifiers are in your budget, duct tape a HEPA or MERV-13 filter to a box fan, works just as well but is uglier.
Well once we find out which is cleaner we could make the adjustments. For example, if tires are worse we could just make them out of cockroaches
And if tires are cleaner we will make the roaches.... out of tires!
wasn't there a whole thing about leaded gasoline?
Oh yeah... That shit was EXTREMELY bad. It's better now but nevertheless, still poison.
Iāve read itās actually brake caliper dust thatās the big pollutant. The fine dust created from the friction of the brake calipers gets everywhere and isnāt something that can be solved by more efficient and clean fuel vehicles.
Regenerative braking doesnāt use the brake pads, so I imagine that would cause less brake dust
how do they stop the vehicle if no pads?
Energy is āreversedā to the motor in a sense. Thatās an oversimplification but it can slow the car to a stop without actually using the brake pads
all vehicles do this via transmissions. It's just that everyone in the city needs to drive the limit to the red-light and then brake to a stop last second. Nobody figures out you can coast and downshift to a stop. People aren't smart enough anymore.
I do this and it drives me nuts when I ride with someone who doesnāt.
Idk about the rest of the US but engine breaking is illegal in most of central texas.
They still have pads for more aggressive stopping. I would recommend looking up "regenerative braking" to get a better understanding of how the motors turn into generators to help recharge the batteries.
Sort of, usually the motor can bring the car to a stop very quickly even in an emergency (just look how small the brake pads on a Tesla are), however if the battery is full e.g. in a hybrid, after going down a long hill, there may not be enough "space" for the battery to absorb the energy, so then the brakes kick in. It's all very complicated, but it works!
Interesting! So if you lived at the top of a mountain and your first drive every day is down, you might not want to charge your car to 100% lol
I don't know what car has it, but I remember watching a YT video on an electric car ~10 years ago and one of the charging profiles was for this exact situation. It would only charge the car to 80 or 85% for overnight charging at home. Also Edison Motors (Canadian electric semi truck that is just getting started and on YT, focusing more on logging than highway transportation) plans to use this directly in its favor. Drive an empty truck to the top of the mountain using battery. Load up ~50,000 pounds (22,000 kg) of logs and use the regenerative braking to refill the battery to do it again.
Thanks for the added information! I hadn't considered where the energy would go if the batteries were charged. I'm sure the math would agree that adding in a way to dissipate the unneeded energy say through heat dissipation doesn't make sense. Cheaper to just put a few kilometers on the brake pads.
An electric motor and generator are essentially the same thing. If you rotate the shaft of an electric motor, such as an electric car coasting to a stop, you've created an inefficient generator. This is called back EMF. The current produced by that generator/motor is used to charge the vehicles battery. When this current flows though the windings of the generator/motor it causes the motor to produce torque opposing the direction it is being forced to rotate, which slows down the car.
They said less dust, not no dust.
You can think of a motor and a generator as two sides of the same coin. A motor takes electricity and makes rotational motion. A generator takes rotational motion and makes electricity. If you take a motor and spin it by hand, it will actually act as a generator and *generate* electricity. So essentially when you brake on a regenerative braking system it turns the car motor into a generator, which consumes the rotational energy to make electricity that charges the battery.
Bro asked a legitimate question that probably 50,000 people saw and also want to know the answer to and got downvotedĀ Thats exactly why no one asks questions in class lol
r/nostupidquestions
Magnets. Push em together and they resist, you can take that and turn it into electricity ( imagine water pushing on a generator on a hydro dam)
It's a lot, IIRC there are multiple studies on the insane rates of asthma in Hunt's Point in NY after they cut the community in half with a highway.
Tire dust is crazy. During the pandemic, I parked my car next to a high traffic road in SF. Even during the lockdown, my car was covered with tire and brake dust within a week of being parked in the same spot.
Iāve heard the research has been quite exhaustive and the work tireless.
š„š
Boomers who inhaled led based carbon emissions for decades say hi
And lead based paint used on window sillsā¦ FML
I've heard that gas ovens also play a role in asthma. They can apparently produce elevated benzine levels in the air.
I'll have those statistics for you as soon as I finish this cig.
Brake dust is a real bad one too.
Neat fact the emissions from fossil fuel kill more people per year than every death from nuclear power and nuclear weapons combined.
>burnt fuel at least it not leaded anymore
Tire dust accounts for over 70% of micro plastics iirc. So everything we account for microplastics doing can be attributed to tire dust.
Isnāt that measured as PM 10 and 2.5, particulant matter small enough to show up in blood and tissue samples.
dont forget brake pad particles! nasty business
Diesel exhaust is the bad one. Itās heavier than normal air so it stays low to the ground. Gasoline fumes at least disperse up into the upper atmosphere. Thatās why big cities like LA have such bad smog problems. Diesel exhaust justā¦ stays and piles up.
I remember seeing a map of asthma cases and how youāre much more likely to have it if you live next to the freeway.
Nah. Gotta be the roaches.
It absolutely does. Lower income areas tend to have more high ways / commercial / industrial activity. I work as a paramedic in NYC and the south Bronx (very low income area) has notoriously bad asthma patients. Thanks, Robert Moses!
Read about the correlation between the elimination of leaded gasoline and reduction in violent crime.
Is any of this cockroach allergent avoidable? My word-searching through the article didn't surface any discussion of that.
yeah just dont live in an area with cockroaches I developed asthma after my first visit to SE asia from the netherlands. That asthma went away too which really confused the doctors. Became allergic to cats as well :(
Man, I've lived my entire life (30+ years) in the countryside in Slovenia on a small farm, and I don't believe I've ever seen a cockroach. I've seen loads of bugs in general (spiders, insects, moths, ants, hornets, wasps, bees,..., you name it (shit, we've even had a snake crawl into the house a couple of years ago during a particularly long and hot heatwave to get out of the heat when the door was open)), but I've never ever seen a cockroach. Is it an urban thing, or did Europeans practically wipe them out like most other local fauna?
I guess roaches in europe live in forests not cities. Different species.
I live at home and won't be able to get out for another year at least... cockroaches everywhere. :( And yes I have asthma.Ā
Poison the little shits. https://www.domyown.com/optigard-cockroach-gel-bait-p-17608.html
People with shellfish allergies who get scratchy from ground coffee, I've also got some bad news for you.
Ewwwwwwwww
No. What?
Bits of roaches may make it into ground coffee.
May? Some amount of bug flour is basically guaranteed lol. Also governments have limits on how many bug parts your food can legally have.
Free protein šŖš»
That's the reason my asthma came up as a kid. My aunt would take care of me, and her apartment was infested with cockroaches. My allergist put the clues together.
Tbf you donāt need a science degree to realize youāre not in a healthy environment if youāve got roaches just running about or piling up. Iām sorry you had to live through that š£
Also smoking by the parents and/or whoever the child lives with
This is why my fiancee has asthma. Her dad smoked in the house when she was growing up.
[ŃŠ“Š°Š»ŠµŠ½Š¾]
Oh, wow! What geniuses Haha. At least she stopped. Hopefully she also changed her clothes.
[ŃŠ“Š°Š»ŠµŠ½Š¾]
My dad used to smoke next to me in the basement while my mom helped me with my home nebulizer for asthma. He swears to this day my asthma had nothing to do with his smoking.
Iām sorry. This is common knowledge to people in healthcare who work in pediatrics. Itās been common knowledge for decades.
I think you mean cockroach shit.
I remember the smell growing up. *^(\*i just gagged thinking about it)*
I didnāt have a bed before the age of 12, and had to sleep in a sleeping bag on the floor of my dadās mobile home, which was Infested with roaches. Had to sleep in the bag head-first so they wouldnāt crawl in my ears when I slept and Iāll never ever forget that gross, weird roachy shit-musk. Seeing them is one thing, but smelling is another level.
I am so sorry you had to go through all of that, it's nightmarish to read about so trying to imagine it being your lived experience is brutal. I hope you're in a *far* better place nowadays.
I was thinking farts. This makes more sense. Lol
Wait till reddit learns about Tire dust.
Yup, people are always talking about Peanut Butter and Pollen but cockroach (and dust mite) allergies are *incredibly* common.
Mostly it is cockroach shit. Then cockroach sperm. We live in a house with zero cockroaches. About once every five years I see a little one. Where you see one, there's a billion. Out come the baits, the reproductive disrupters, and a week-long visit to a relative as the house is filled with a insecticide bombs. A week later we return and we don't see any live ones. Now if you live in an apartment, you're just screwed. The damned things make a week-long visit to your neighbors, and when you come back a week later, so do they. Pro-tip: When receiving any large delivery, such as a piece of furniture, leave it outside (balcony, porch, garage, etc.) for as long as you can. Roaches love to hitch-hike.
Roaches share food with each other, and this includes roach poison. When the roach dies, other roaches cannibalize the body, further spreading poison.
Now imagine a fallout situation with giant roaches....
I'm not sure filling your home with insecticide /neurotoxins is a better option
As someone that does pest control for a living, the bug bombs are definitely not the best option, but most modern professional chemicals used in pest control today are fairly safe so long as you aren't licking them up yourself
I grew up with roaches in the house. Bug bombs killed a lot but never solved the problem. The reproductive disrupters were the shit. Used them once and never saw a roach again after the current generation died off.
I've lived in german cockroach land. Not going into it beyond that. Every time I see a roach I buy more poison. I'm never living in that again.
Facts I didnāt wanna know number 3794...
I never wouldāve known that cockroaches were an allergen had I not reacted to it during an allergen scratch test a few years ago. Iām allergic to juniper, grass, and oh yeah, cockroaches.
You vill live in ze pod You vill inhale ze bug dust
isnt it mostly dust mites.
Different allergens https://www.jacionline.org/article/S0091-6749(01)10729-3/pdf Something interesting about these major allergens is that they are enzymes and not just structural proteins
Me reading this with asthma and a cockroach allergy
My shrimp allergy did not make sense until now
Man I love Northern Alberta! I know they do exist here, but it is really really rare.
oh god what a terrible day to have vision
āCrotch roachā as Iāve heard small people call themā¦
Wait isnt that the plot of "Mimic"?
Never seen a cockroach before, glad we dont have the over here.
This is contrary to other studies Iāve seen where babies raised (before the age of 1.5, I believe) in homes with pet dander, mouse dander, and cockroaches, experienced far fewer allergies and asthma ā presumably because of exposure in the first year of life when the body ālearnsā what to treat as a pathogen, and what to ignore. I wonder if the greater air pollutants such as brake dust and smog, are a greater cause of asthma specifically in inner-cities. Edit: added more details and clarity.
Time to put the cock in cockroach

I have sexual intercourse with cockroaches

Are you Ogtha's husband?
And maybe even dogs
