Animals, particularly birds and bat, may be involved in bed / bat bug dispersal. Piles of cast nymphal skins often accumulate in bedbug hiding places. Figure 3 shows piles of shed skins at the base of bed headboard. Lectularius is also forming a resistance to other insecticides, according to a study published online April 10, 2017, in the Journal of Economic Entomology. The scientists defined “”reduced susceptibility”” as a population in which more than 25 percent of the begbugs survived after seven days of exposure to the particular insecticide. Instead, they live in mattresses, fabrics, furniture, luggage, and pieces of wood.

Bed bugs are wingless insects, roughly oval in shape, 4-5mm long when fully grown, and are fast runners. They are rust brown in colour and change to a deeper red brown following a blood meal. дървеници видове are dorsoventrally flattened and being thin means that they can hide in narrow cracks and crevices, making detection often very difficult.

Early signs of bed bugs are uncomfortable, itchy nights in bed, marks on arms and shoulders, and an unpleasant odor resembling a wet towel. Symptoms of bed bug bites are skin rashes of red, itchy, flat welts in zigzag lines or clusters.

A number of other related pests resemble bed bugs in habits and appearance. Proper identification usually requires magnification and experience with distinguishing the different species. Two types of bed bugs prefer human blood meal, while one prefers bats but will settle for humans.

At temperatures above 21°C (70°F), eggs hatch in about 10 days. At lower temperatures, hatching may take as long as 28 days. But their narrow body shape and ability to live for months without food make them ready stowaways and squatters. Bedbugs can easily hide in the seams and folds of luggage, bags and clothes. They also take shelter behind wallpaper and inside bedding, box springs and furniture. The ones that feed on people can crawl more than 100 feet in a night, but typically creep to within 8 feet (2.4 m) of the spot its human hosts sleep, according to the CDC.

Caregivers, firefighters, and other service providers are sometimes required to enter and assist in bed bug-infested dwellings. In doing so, there is the potential to transport the pests home or to the workplace. As noted earlier, bed bugs do not fly, or jump onto people and pets as fleas do. During the day, the bugs usually remain hidden, becoming more active at night when seeking a host. Consequently, the chance of picking up bed bugs by simply walking into an infested dwelling during the day is unlikely. The risk may increase while providing care but can be lessened by taking a few precautions.
