1. Bed bug?

Yes, bedbugs have a Latin name: Cimex lectularius. A name which means exactly what we know it as They usually feed on you when you go to sleep, and so beds are 70% of the focus of infestation.

The remaining 30% is housed in other places in the room, the cracks of baseboards, and door frames, among other things.

Bed bugs can attack anyone. It’s a mistake to link them with poverty or cleanliness problems. So, if you know someone who has them, you shouldn’t think it’s because of their bad hygiene habits.

3. It hasn’t been proven that they transmit serious diseases

4. The bites don’t look the same

You may have become familiar with what bed bug bites look like after some internet research. But this is only for reference, because the truth is that their bites don’t follow the same pattern for everyone, even if both people have been bitten by the same bed bug.

6. You don’t need to see them to have them

There are cases of low infestation and people overlook the symptoms. It takes an exhaustive search to find the pest. Some signs are black spots (fecal matter) that you may find embedded in mattress seams.

8. They’re expert anesthesiologists

In most cases, bed bugs keep us asleep while they’re feeding on us. This is thanks to the fact that their saliva is composed of elements that act as anesthetics and stimulate blood flow, which helps to make feeding quick and painless.

After eating, they go into hiding for 5 to 10 days.

9. They’re resistant

These insects can survive several months without feeding, which means that they can stay anywhere for a prolonged period of time until they’re approached by a host. On the other hand, they can withstand temperatures ranging from 2 to 50 degrees Celsius. So, it should come as no surprise that they can inhabit a hardware store without much trouble.

10. They’re very smart

These insects are very smart. They sneak around and hide inside the seams of mattresses, behind electrical devices, in bags, and other places we wouldn’t think of.

During the day they hide. And, at night, the carbon dioxide exhaled by the body activates them.
