Bed bugsThe human bed bug is an ancient pest. Experts believe bed bugs fed on the blood of pre-historic humans when they lived in caves. When people moved from caves into tents, huts and houses, bed bugs moved along with them.

After WWII, effective, long-lasting insecticides made bed bug infestations so rare most Americans never saw a bed bug. This also meant the last couple generations of homeowners (and pest control companies, too) have never had to deal with a bed bug infestation.

Times have changed. Entomologists worldwide have noticed a recent upsurge in bed bugs. Why this has happened is unknown.

Bed bugs usually attack humans, but may bite other warm-blooded animals, including pets. During the day, bed bugs hide in groups in bedcoverings, mattresses, box springs, bed frames and cracks and crevices near the bed (photo above). They use heat-seeking thermal receptors to find their sleeping victims at night.

Bed bugs feed on blood as their only source of nutrition. Feeding occurs once during each of the five immature stages to grow and molt to the next stage. The adult female feeds periodically on blood to produce eggs.

Bites are often found on the upper body: neck, arm and shoulder. People may not feel the bite, but some people are sensitive to the bite which may become inflamed.
