Bed bugs originated in the Middle East and were transported around the world by human beings. Initially discovered in North America in 1748, bed bugs were virtually eliminated in the U.S. during the 1940s through DDT. However, due to increases in international travel and pesticide regulations, they have become more common in recent years. Even though bed bugs are associated with over 25 different disease organisms, they are not known to transmit diseases to humans. However, their bites may result in itchy, red welts often found in lines or clusters on the body.
Biology and Behaviour
- These bugs are 3/16 of an inch long, oval and flattened, and can survive 6-7 months without feeding.
- Females deposit 1 to 5 eggs per day over two months, an average of 200 eggs per female.
- Life cycle: egg to adult in 21 days at 86°F; egg-laying is suppressed below 60° F.
- Bed bugs have a simple metamorphosis (egg-nymph-adult) with five nymph instars.
- These bugs are nocturnal, feeding after dark. They only feed on blood (primarily human).
- They cause an allergic reaction 80% of the time.
- They typically live within the cracks and crevices in or around bedding and furniture.
- Large infestations emit a sickly-sweet, raspberry-like odor.
- They deposit fecal pellets (spots) here and there on surfaces (e.g., corners of furniture).
- Introduced into new areas via bed bug-infested humans, belongings, and furniture.
