They are creatures from hell.
If you are sensitive to the bites, it’s MUCH worse than mosquito bites – think painful, weeping blisters that burn if a breeze so much blows across them the wrong way, nevermind laying down, or clothes rubbing on them.
A single bug feeds on you multiple times in a night, leaving what’s sometimes referred to as ‘breakfast-lunch-dinner bites’ because the clusters/lines of bites they leave are very distinctive. Each bite takes days, even weeks, to go away, and they itch/burn the whole time – so if you’re infested (50-100+) imagine waking up with any accessible skin (including your face) covered in burning, persistent bites that there’s no real relief for.
It ruins your ability to rest – every tickle or itch starts making you bolt up in horror to turn on the lights and check. Long after they’re gone, years after you’ve been rid of them, you will still experience a surge of adrenaline from a hair moving the wrong way.
They reproduce insanely fast; a fertilized female lays 5-7 eggs a day, the eggs take around 2 weeks to hatch, and then they’re able to reproduce about 3 weeks after they hatch. A female will lay hundreds of eggs over her life after being fertilized even ONCE. This means one fertilized female could come into your home, and within a year if the infestation is not dealt with fast and harshly enough, you can have THOUSANDS of them.
While they prefer to stay close to their prey (in the bed, headboard, bedlinens) they can hide anywhere a sesame seed would fit – between the pages of a book, inside cardboard, cracks in the baseboards, carpeting, seams in cushions, etc. If you try to get relief by treating your bed with chemicals, all that happens is that they disperse into the walls and other nearby hiding places, and become harder to find and eliminate as their numbers swell.
They have evolved to be keenly attuned to everything about their prey (humans) when it comes to temperature, lighting, movement, breathing, etc, so that they are most attracted to you when you as sleeping and vulnerable. They will hunt you down if you move to another room to sleep at night. If you put your bed up on risers/dishes of oil/put double-sided tape all around so they can’t get to you, they will crawl up walls to the ceiling and drop down on you to get at you.
If they are consistently denied food (say you pack up everything you have in tubs and plastic bags or something, and accidentally miss a couple hiding in your things), they can go into hibernation – in ideal conditions, for almost 2 years without feeding. The eggs are smaller than a poppy seed, and can remain viable and unhatched in the right conditions for a similar length of time.
Most of the chemical treatments that work against adults do not work on the eggs, so unless you do multiple scheduled treatments, you’ll just have new waves hatching every so often after the last round of adults was killed off. Each time you get your home chemically treated, you will have to leave it and stay somewhere else because the chemicals are dangerous to you as well.
If you live in a building with shared walls, even if vents and things from unit to unit aren’t connected, if someone else gets infested and they don’t treat the entire building at once (only treating the immediately affected rooms) it’s just like only treating the bed – they will disperse into neighboring units, and seek shelter in any little crack or crevice they can find.
Sufficient heat is the only guaranteed way to kill off an infestation all at once – adults, nymphs, eggs – and they make specialized heaters for this, both for heating up rooms, and for placing your belongings into to heat treat anything that might be hiding eggs or bugs. Many people accidentally burn their houses down every year trying to DIY treatments because this is expensive – thousands of dollars per round of treatment, either chemical OR heat.
It doesn’t matter if you or your house is clean or dirty – you can get bedbugs by going literally anywhere that other people go. The store, offices, clinics, movies, public transportation, etc. While adults won’t live in your clothes, they’ll hitchhike on them – so anywhere people spend time holding still, someone with an established infestation can be carrying eggs or hidden adults that end up dropped off in a public space that then end up stuck to or climbing onto others. All it takes is one fertilized female riding home with you unseen on your clothes, a bag, your jacket.
Bedbugs exist in pretty much every country – anywhere where it is cool enough indoors for people to live, bedbugs can live also. Infestations are actually on the rise in some countries due to shorter, warmer winters meaning they can be active for longer (since cold temps generally only put them into a dormant stage, not kill them).
Hotels and other hospitality locations that care about prevention will routinely pay for specially trained sniffer dogs that can detect the smell of bedbugs, and shut-down/cordon off buildings as soon as anything is found, because it is more costly to handle a major infestation than to destroy a colony before it gets the chance to hit critical mass.
Even so, a hotel has no way of being able to tell if the guest immediately before you dropped off hitchhikers; even a high-end hotel isn’t flipping the mattress over to steam and vacuum the mattress and box-spring when they change out the bed linens.
Hotels are often the first choice of people trying to get a rest from an infestation, or needing a place to stay while getting their own place treated.
If you ever stay anywhere away from home where other people have been, always put your luggage in the bathtub first before unpacking; then check for signs of bedbugs in headboards, under the mattress, in the seams of the box-spring, etc. There are guides with pictures on what to look for. When you get home, make sure any clothes that travelled with you go into a high-heat wash and dry cycle. Bag up any luggage carriers than cannot be washed or tumbled; consider treating their insides with diatomaceous earth until their next usage.
It might seem like an annoying extra effort, but it is a tiny amount of labor to save you from experiencing what will feel like an unending hell if you ever bring bedbugs home. An infestion will completely ruin your life and mental health. Pray you never have to deal with them.
