Bed bugs are small insects that are difficult to detect with the naked eye, and that usually hide in places like mattresses, sheets, furniture, carpets, cracks in chairs and cabinets, and even behind the wall paper, going unnoticed by most of us.

These insects feed on human blood and do so especially at night. His saliva has a very particular characteristic and that is that it prevents the blood from coagulating while they suck it, so that they can feed themselves without being hindered by anything. Once they have satiated, the bedbugs scurry and hide again to repeat the same cycle, day after day.

Although these little animals seem impossible to detect, they leave us some clues that indicate their unpleasant presence, and these are dark and bloody spots on the bedding, in addition to a disgusting smell and small pieces of skin that they leave once they have moved.

Now that you know about bed bugs, you’re probably wondering: where do they come from? Well, one of the main reasons for the appearance of these bugs has to do with the fact of having pets at home and let them sleep on furniture or in beds, since the bed bugs usually climb cats, dogs and other animals to feed on their blood, and may end up feeding on us.

In addition to this, bed bugs can also appear as a result of trips abroad. It may sound a little weird, but when we travel to non-industrialized areas with few hygiene supplies, we take the risk that the bugs that live there will get into our luggage and travel with us back home.

Types or species of bed bugs

Well, the truth is that the world of bed bugs is quite broad and there are different types of them. In this animal group we can consider all the hemipteran insects that have a kind of pointed trunk or mouth that they use to suck fluids, whether it is the sap of the plants or the blood of humans or other animals.

When this happens, it is very important to treat the bite and not overlook it, as other more serious discomforts may appear on the skin and even certain health problems.
