We’ve all had to deal with a small, unwanted creature in the house: a spider, an ant, or even a slightly overly curious mosquito… But did you know that a certain type of insect, seemingly harmless, can pose a real risk to your home? It doesn’t just pique your curiosity: it can affect your well-being and that of your loved ones. Focus on a surprise guest that’s best never to be ignored.
How to recognize this disturbing intruder?

Commonly called the « blood-sucking bug, » this dark-looking creature has an elongated, dark brown body with reddish or orange highlights on the sides. It has a pointed head, long, mobile antennae, and… it can fly! But it’s its stealth that makes it problematic: it likes dark corners and cracks in walls, and comes out at night while everyone is asleep.
Why this insect can be a problem
It’s not its appearance that’s worrying, but what it can cause. When it feeds—yes, it’s looking for blood like mosquitoes—it can leave behind biological residues that, when in contact with the skin or mucous membranes, can spread pathogens . It’s this ability to interact with our bodies indirectly that makes all the difference. A simple scratch at the wrong time… and the risk is there.
Where does she like to hide?
These bedbugs are generally found in rural areas or on the outskirts of cities, especially in homes with cracked walls, old roofs, or poorly insulated roofs. But they can also appear in urban areas if the conditions are right. They particularly like:
- cracks in walls, ceilings and window frames ,
- the underside of mattresses or box springs ,
- dark areas behind paintings or furniture ,
- sheds, garden sheds or animal outbuildings .
