What Is A Bed Bug?

The bed bug ( Cimex Lectularius ) is a parasitic insect of the Cimicidae family  . She is able to locate us  thanks to the carbon dioxide and the heat that our body gives off. She takes advantage of our sleep to sting us. Both male and female stings and sucks human blood under the skin for 3 to 15 minutes, then hides for several days to digest it. When it bites , the bedbug injects some of its saliva under the skin of its host. This saliva contains an anesthetic and an anticoagulant which thins the blood to facilitate its aspiration. ” The bedbug bites on averageonce a week for food “, specifies Jean-Michel Berenger, entomologist.


It has a lifespan of 5 to 6 months. However, it can live more than a year without feeding when it goes into a state of dormancy.

Bed bugs are visible to the naked eye and measure 4 to 7 mm : ” An adult bed bug is the size and color of an apple seed when it is engorged with blood “, describes Jean-Michel Berenger . Their bodies are  oval and flattened in shape,  which allows them to squeeze into every nook and cranny. During the day, the bedbug tends to hide. When night falls, she comes out of her hiding place and goes to look for food. To see them, you often need a flashlight.

Where To Find Them?

These insects hate light , so they hide in dark corners and are active at dusk, usually in the late afternoon and at night. “The bed bug is aptly named and tends to hide in bedrooms, particularly around the edge of the mattress or the headboard , as close as possible to sleepers, ” says the specialist. Bed bugs also love to nestle in sofas, upholstered seats, rugs, carpeting and even in wheelchairs. They can also snag on curtain rods, fans and inside electronics.

But bed bugs can appear anywhere. Indeed, when insecticides are used to remove them, bed bugs take refuge elsewhere and are therefore not limited to the bedroom. This is why they can be found in the space of a few weeks hidden in cracks in walls, floors, furniture, in electrical outlets, behind furniture or paintings.  ” If there is a suspicion of bed bugs, it is possible to call on detector dogs to locate, thanks to their sense of smell, the areas infested by adult bed bugs, but also the larvae and eggs “, specifies our interlocutor.
