Bed Bug

Natural Habitat

Bed bugs are found worldwide. They typically inhabit human dwellings, preferring to hide in cracks and crevices close to their hosts. Common hiding spots include mattresses, bed frames, box springs, headboards, nightstands, behind wall hangings, and in electrical outlets. They can also hitchhike on luggage, clothing, and furniture.

Diet & Feeding

Bed bugs are obligate hematophagous insects, meaning their only food source is blood. They primarily feed on the blood of humans, but can also feed on other mammals and birds if humans are unavailable.

Behavior Patterns

Bed bugs are primarily nocturnal, feeding on hosts while they sleep. They are attracted to carbon dioxide and warmth. They tend to hide in cracks and crevices during the day, emerging to feed at night. Females lay 1-5 eggs per day, and nymphs typically molt five times before reaching maturity, requiring a blood meal between each molt. The entire life cycle from egg to adult can take a few weeks to several months, depending on conditions and food availability.

Risks & Benefits

Potential Risks: Bed bugs cause itchy red welts from their bites, which can lead to secondary skin infections from scratching. While not known to transmit diseases to humans, their presence can cause significant psychological distress, sleep deprivation, and allergic reactions in some individuals. They are a major nuisance pest. Benefits: No direct known benefits to humans or the ecosystem.
