Bed Bugs

Bed bug bites may appear as small clusters of itchy red bumps on hands, legs, and other areas of the body. They may also cause rashes, allergic reactions, psychological distress, or… nothing — around 30-60% of people have no reaction to bed bug bites.

Bed Bug (Adult)

Cimex lectularius

Bed bugs are small, parasitic insects that feed on our blood while we sleep. During the day, they hide in dark, narrow spaces like the seams and gaps in mattresses, bed frames, and walls.

They spread to new locations by crawling into neighboring apartments or by hitching a ride in personal items like bags and luggage.
