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 .

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.

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.
