  2. Bed Bug History Bed bugs have probably been a companion of humans since the time of cave dwellers. Bed bugs feed entirely on blood and prefer human blood, but may also feed on poultry and other birds. Bed bugs do their feeding at night when their sleeping human hosts are easier & safer to feed on. Bed bugs were a common household pest until the 1940s when chemical pesticides were developed. Bed bugs became rare in the 1950s and did not become a problem again until recently.

  4. nymph Photo by Dr. Susan Jones – Ohio State U. The Bed Bug Life Cycle Bed bugs go through an egg stage, and five nymph stages before they become reproductive adults. Each nymph stage must have a full blood meal before it can grow into the next stage. Adult females must have a blood meal to be able lay eggs, and then will lay 5 - 20 eggs over the period of a week before seeking another blood meal

  5. A Bed Bug Life Necessity A harborage that is relatively close to a source of blood. Bed bugs will live as close as possible to a frequently used bed.

  6. Some Common Bed Bug Harborages Along seams, folds and piping of mattresses, upholstered furniture, and between cushions. In holes, cracks and crevices found in bed frames, bedside furniture, lamp bases, etc.

  7. Other Common Bed Bug Harborages Under picture frames. In bureau and cabinet drawers. Behind loose baseboards. Under carpet edges. Behind peeling wallpaper. Along curtain seams and in curtain rod fixtures. In cracks and holes around window frames. In electrical outlets and electrical appliances (e.g., clock radio, lamp). Along the corner of the wall and ceiling above the bed.

Brown or black fecal stains around a harborage. Bed bugs take large blood meals and void digested blood in and around their hiding place.

  9. Common Signs of a Bed Bug Infestation 2. Eggs, empty egg cases and shed exoskeletons (skins) from molted bugs Bed bugs glue their eggs to items on or near a bed. 3. Blood spots or stains on bedding (sheets)

  10. Photo from Fletcher et al. , 2002 Photo by Dr. Susan Jones – Ohio State U. Other Signs of a Bed Bug Infestation 4. Bed bug bites Bed bugs mostly bite exposed areas of skin that are not covered with clothing. A bed bug will move and bite repeatedly until it finds a good place to feed. Thus, bites often appear in a line or in a patch.

  11. Photo by Leverkus et al., 2006. Other Signs of a Bed Bug Infestation 4. Bed bug bites Bed bug bites can (rarely) cause severe bullous “blister-like” reactions in certain people. Bites do not always serve as good evidence of a bed bug infestation because anywhere from 30 % to as many as 50% of people may not have any noticeable reaction to bed bug bites.

  12. How Bed Bugs Could Come Into a Pre-school Facility 1. Child-borne introductions Children can bring bed bugs into a facility when their home is infested with bugs. Eggs could have been laid on the child’s clothing, shoes, backpack, books, toys or other personal items and brought to the facility where they hatch. 2. Introduced on previously owned objects purchased for the facility. Bed bugs and their eggs can arrive on second-hand mattresses, furniture, books and other items purchased at yard sales or donated by children’s parents .

  13. How Bed Bugs Could Come Into a Pre-school Facility 3. By crawling from adjacent buildings. Bed bugs can also move, through cracks in walls or along wire conduits and pipes from an infested apartment .

  14. Can Bed Bugs become Established in a Day Care Center or Pre-school? Unless staff or children sleep at the facility during the night time, or hours of darkness, introduced bed bugs would be quite unlikely to survive. Bugs must feed at night and will not bite active, moving people during daylight hours, so any introduced bugs would eventually perish of starvation.
