Bed bugs are biting insects that feed on the blood of people while they sleep.
Bed bugs can bite only one person in a group of people sharing a bedroom. They rarely bite pets.
If they are not exterminated, they reproduce and spread rapidly. When their numbers grow, bed bugs become a nuisance. This constitutes an infestation. The effects of a bed bug infestation can have very significant consequences on the health and quality of people’s lives.
