Why Cockroaches Are So Hard To Kill

Why Cockroaches Are So Hard To Kill

– [Narrator] You might not
want to think about this, but over 3500 species of cockroaches live on this planet. The good news? Only about 30 of those species have adapted to live around humans. The bad news? 30 species of cockroaches
can live around us! Roaches are one of the most
common pests in the US. So it’s no surprise that humans are always trying to kill them. But no matter how many
times we stomp them, squash them, and bomb
them with toxic chemicals, these pesky pests always seem
to pop up time and time again. So what’s going on? Let’s take a closer look at the roach you probably know better than you’d like. Periplaneta Americana. Aka, the American Cockroach. But this name is misleading. This guy is actually
from Africa, not America. It made its way to the US by infesting boats in the 16th century, and it’s been spreading to
almost every corner in the world ever since. It turns out, it’s one of the largest
species of cockroach around. But that’s not the only
big thing about it. New research has revealed
that it has a massive genome. One of the largest of any studied insect. And may of these genes are
exactly what make this roach a master survivor. Let’s start with the genes associated with something called Chemoreception. That’s how roaches smell
and taste their environment. Turns out they’re actually way better at sniffing out and eating
food than most other insects. The American roach has 154
olfactory receptors for smell, and 544 gustatory receptors for taste. More than any other insect on the planet. As a result, these cockroaches
are not picky eaters. Sure, they like cheese, meat
and sugar like the rest of us, but they’ll also go for
things like cardboard, book bindings, human
toenails, rotting meat, blood, excrement, and even each other. That’s right, these
roaches have been known to eat other dead or crippled cockroaches, all in the name of survival. It sounds gross, but this diverse diet makes it easy to find a
meal just about anywhere, even if it’s poisonous to most animals. This roach has a bunch of
genes called Cytochrome P450s, which help it withstand
poisonous chemicals, like peppermint. These genes code for
detoxification enzymes, which keep the insect safe. On top of that, this roach has
a super-strong immune system that seeks out and kills
harmful microbes and fungi, making the most unsanitary environment look like a five-start hotel
to the American cockroach. Not gross enough yet? Well consider this. Cockroaches can live nearly
a week without their heads. Yeah, that’s not a myth. They don’t have a highly
pressurized network of blood vessels like humans,
so they don’t bleed out. Instead, their necks actually
seal off the opening. They can’t regenerate a whole head, but roaches to have an impressive set of regenerative superpowers. For up to the first two years of its life, the American roach goes through a series of regenerative molts as
it matures into an adult. During a single molt stage,
it can replace lost limbs. And over a series of molts,
it can regrow antennae and even its eyes. Roaches may be hard to kill, but there’s an easy way to keep
them clear of your kitchen. Cleanliness. A roach just won’t survive
in unsanitary conditions, it actually enjoys it. Its heightened senses mean it actually relishes rotting food. So, store food in airtight containers. Cover trash bins, and
keep your basement dry. It might also be smart to
plug holes in your walls, unused electrical outlets,
and especially drains, since get this, roaches can use your plumbing
to climb up from sewers into your bathroom sink. It might not eliminate the risk entirely, but it can’t hurt, and it will certainly
make you feel better. However, we can’t promise
it will keep them out of your nightmares. (dramatic music)

I saw an advertisement for this product, saying that it keeps the roaches, rats and all other harmful creatures away from your house by emitting an ultrasonic wave that extremely irritates their nerve system. Not sure if it is really effective, but next time I ever have to live in another cockroach-infested house, I will certainly try this.

The roaches were one of the main reasons why I left Texas, seriously.

Geeze!! Am I the only one who uses rubbing alcohol in a spray bottle? They die pretty quickly and easily. One pump and, "goodbye."

I don't tuck my covers in at the feet, so I've awakened to a big one walking around on my foot and in my relaxed state, just kicked it off and went back to sleep.

I lived in California for a year and had to deal with these…Never realized how thankful I was for a winter kill in Utah….

They could create superhumans if they discover how to transfer and somehow alter our DNA for their resilience to bacteria and poison!

Spiders —tameable but scary
Ants— annoying yet helpful
Flies—annoying buggers
Cockroaches—Not your freind
Scary, gross, annoying, creepy,
And can fly

Hi, I'm Derek Bum, say goodbye to your cockroaches with new… KITCHEN GUN!!!!

A cockroach last words to a man : Go Ahead kill me you "coward".You are just jealous i make your wife scream more than you do when i climb her

There once was a cockroach outbreak in my house I was watching a movie in my mother’s bed at night when the movie ended I SAW A BIG ASS ROACH CRAWL FROM BEHIND THE BED i ran out fast then I go to my bed then I see another roach so I threw the blanket on it and ran out the bed then i went in my sisters bed and I saw another roach this time I killed it.

Don't smash them, it spreads eggs and bacterias all around if you do that. I just killed one using spray and watched for 10 minutes until it completely died.
