10 Things You May Not Know About Cockroaches

Maybe you think cockroaches are the filthiest beings in the universe, we understand. But there are some very curious facts about small insects that can make them a little less despicable. Check it out:

1 - Headless

A cockroach can live without its head for weeks and will only die from hunger. Naturally they can stand it for a long time without ingesting any food or water, and their breathing is done through spiracles throughout the body, so the lack of the head does not influence so much.

2 - Dish Good

When there is some sort of choice, cockroaches often opt for sweeter foods, but when times get tough, they can eat everything: glue, grease, soap, leather, hair, and of course, feces - perhaps because of it. That's why people find them so gross. Oh, there's only one thing they don't like so much: cucumber, and no one can explain why.

But they only resort to this kind of food when they really have absolutely nothing at all to eat, as a last resort: before reaching this stage they can spend weeks without eating anything at all. On the other hand, this feature makes them also great consumers of organic waste.

3 - The Flash

Cockroaches can reach a speed of 3.2 km / h. Did you find little? Well know that relating to your body size, this is very fast: if they were the size of a cheetah, it would be the equivalent of moving at over 80 km / h.

In addition, thanks to its three pairs of legs and an extremely sensitive system for detecting changes in air currents, a cockroach has an extremely fast reaction time, up to 8.2 milliseconds. In addition, of course, to be able to change your direction abruptly while giving "correctness".

4 - Velhiiiiinhas ...

Long before humans thought of inhabiting this planet, cockroaches were making their nonsense here. Insects have already shared the earth with dinosaurs, and it is estimated that cockroaches as we know them have been around 200 million years ago, while their predecessors had been blowing out antennas 350 million years ago. So before the egg and the chicken we had cockroaches. Lots of cockroaches.

5 - This family is very close

Cockroaches are extremely sociable creatures and are able to recognize members of their own families, with different generations living together. It's like that mess of uncle, aunt, grandma, dad and mom in the same house.

So too, they may feel lonely when alone, and if they stay that way too long, they may even get sick. So think about it, maybe that cockroach that showed up at your house just wants a little company!

6 - Hmm ... What is that smell?

Cockroaches fart. You may never have seen it, but according to a British pest control company, in terms of body weight, cockroaches emit more methane than any other creature in Britain.

The American cockroach - the best known - even releases 35 grams of methane, more than 43 times its average body weight.

7 - No plague!

Although many regard cockroaches generally as plague, of the nearly 4, 000 species in the world, only about 30 live in urban areas, the most common being the American cockroaches and the German cockroaches (also known as cockroaches).

And if you find big urban roaches, be aware that in the tropics - and to anyone's surprise in Australia - some forest-dwelling species can grow to 18 centimeters in length or 10 centimeters in length. Better to stick with the common ones, right?

8 - "Welcome to Barataville"

A study conducted in New York found that cockroaches have their own "neighborhoods": their genetic types varied by region and grouped into similar types.

9 - They like to be touched

The cockroach is a tigmotropic insect, meaning she likes to feel something solid in contact with her body, preferably on all sides. This explains why they always get stuck in tight cracks and holes, but really, just about their size.

No, they are not resistant to a nuclear disaster.

True, they are far more resistant to radiation than other non-insect beings like us. They can hold up to around 20, 000 rads (radiation unit), but the Hiroshima bomb, for example, even emitted around 34, 000 rads. So even though they have been on the planet for a long time, if such a disaster were to happen, they would hardly be the ones to stop here.
