Forget what you know about bed bugs. Avoiding and getting rid of them is pretty simple.
And thankfully, there are no toxic chemicals involved.

Mark Rober subjected himself to bed bug bites in the name of science.
"Good night! Sleep tight! Don't let the bed bugs bite!" This sing-songy rhyme that has been around for centuries alludes to the fact that bed bugs were prevalent in the past. After a significant decrease post-WWII, however, the sneaky pests have been making a comeback. Since the 1990s, bed bug infestations have risen dramatically, leading people to look for ways to avoid and get rid of the blood-sucking little buggers.
Unfortunately, a lot of the information about how to do that is flat-out wrong. Popular YouTube science communicator Mark Rober invites viewers to forget what we think we know and go on an educational journey with the leading bed bug researchers at Rutgers University's urban entomology lab. Not only did Rober subject himself to bed bug bites on purpose to see what happens when they feed, but he also conducted a series of experiments in the lab to find out what is actually effective at killing them and what is not.

Bed bugs have a reputation for being nearly impossible to get rid of, which isn't really the case, according to Rober. When you know what works, it's actually a fairly simple process to kill an infestation. And the good news is that it doesn't entail any toxic chemicals—in fact the pest control chemicals sold for bed bugs don't work at all, according to Rober's tests.
In the process of learning about bed bugs, Rober shared a few "super wild" facts about the infamous creatures.
Fact #1: Bed bugs can live 3 to 10 months without feeding.
Eek. No wonder it seems like it's impossible to get rid of them. Starving them doesn't work. They can live in the resting stage for 3 to 6 months, and if the environment is cold enough, they can survive around 300 days, or 10 months, without eating.

Fact #2: Bed bugs don't transmit disease
Some good news here: Unlike blood-sucking mosquitoes, bed bugs don't carry or transmit disease. The bad news on the front is that because they don't pose a disease threat, only an annoyance, there's not a big incentive to fund research to eradicate them.
Fact #3: Bed bugs are attracted to vertical objects
In one of Rober's experiments, he placed a dish with a cylindrical vertical post inside it an a dish without a column, and nearly all of the bed bugs in the enclosure ended up in the dish with the column. "If you think about it, humans sleep at the highest elevation any given room. So their logic is just crawl up any vertical surface you see until you eventually find a warm-blooded meal at the top."
Part of how they find humans is by smell, which is why certain strong-smelling items can act as a deterrent for bed bugs. In Rober's experiment, Bounce dryer sheets, moth balls, baking soda, and essential oils all seemed to repel bed bugs (as opposed to ultrasonic pest repellers, which appeared to have no effect). However, none of those things did anything to kill them.

Fact #4: Before 1950, one in three homes had bed bugs
Yikes. Even with the resurgence, we're still nowhere near those numbers, thank goodness.
Fact #5: The way bed bugs mate is weird
The term used to describe it is called "traumatic insemination," and really, you should just let Mark Rober explain it with his visual metaphor. Start at minute 11:30.

Two things work well to kill bed bugs—diatomaceous earth and heat
In testing chemical sprays, foggers, and other items marketed for killing bed bugs, Rober found a "superstar" in a natural, non-toxic substance. Diatomaceous earth—pulverized fossilized remains of tiny aquatic organisms called diatoms—was the most effective at killing the buggers with a 90% mortality rate after 10 days as opposed to 12% with the Hot Shot bed bug spray. Diatomaceous earth is mostly silica, which absorbs moisture, and when the silica dust sticks to the bed bugs as the walk through it, it dehydrates them. A light dusting of diatomaceous earth around all the cracks and crevices of a room is one way to kill off an infestation, though that process can take days.
The other way to kill bed bugs is heat. Steam kills bed bugs, as does heating up a room to over 122 degrees Fahrenheit does the trick. Temps over 122 degrees kills bed bugs instantly, and as Rober points out, there's no way for them to build immunity to this kind of treatment. So steamers and clothes dryers set to high are the average person's best bet for killing off bed bugs if they have them. The "nuclear option" is to have a pro come in with big heaters and cook your home for a day.

How do you avoid getting bed bugs in the first place?
An ounce of prevention is worth a pound of cure, and that's true for bed bugs especially. Avoiding an infestation if there's already one in your apartment building is trickier, but a lot of people inadvertently bring bed bugs home from hotel stays. Checking the underside of a hotel mattress as soon as you come in the room is a good habit to be in. Bed bugs poop a lot, and there will be spots along the edges of the mattress if bed bugs are present.
The other tip is to use the luggage rack to store your suitcase instead of leaving it on the floor or furniture and to hang clothes on the closet hangers instead of putting them into the hotel room's dresser drawers. Some people may even put their suitcase in the bathtub, at least until they've checked the bed for signs of poop.
Nobody wants to deal with bed bugs, but at least now we have clear evidence of what actually works to get rid of them and what doesn't. Cook them with heat/steam and dehydrate them with diatomaceous earth, and take some simple steps when traveling to lessen your chances of getting them in the first place.
Sleep tight, everyone!

There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.

Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
