Once a pest of the past, bedbugs now infest every state in the U.S.. Cimex lectularius—small, flattened insects that feed solely on mammalian and avian blood—have been living with humans since ancient times. Abundant in the U.S. prior to World War II, bedbugs all but vanished during the 1940s and ’50s thanks to improvements in hygiene and the use of pesticides.

This is a particular problem for hotels and apartments, where turnover of occupants is constant. Bed bugs are small and agile, avoiding detection by crawling into concealed locations. Acquiring secondhand beds and furniture is another way they can be transported into buildings. The bugs can also be inadvertently carried in on one’s clothing, shoes, wheelchair, etc.

Males preferentially direct their sexual interest to recently fed females, which undergo ∼5 traumatic inseminations per feeding . High female mortality results from these numerous traumas, but other explanations have also been proposed .

It is found in temperate climates throughout the world. Hemipterus, found in tropical regions, which also infests poultry and bats, and Leptocimex boueti, a relative of C.

People also have widely varying reactions to bedbug bites. Some people have little visible reaction to the insects’ nibbling — they don’t develop lesions or bumps or pustules at all.

Repeat visits may be necessary to ensure all bedbugs at various stages of the lifecycle have been eradicated.

Bacterial skin infection may occur due to skin break down from scratching.Systemic poisoning may occur if the bites are numerous. Exposure to bed bugs may trigger an asthma attack via the effects of airborne allergens although evidence of this association is limited. There is no evidence that bed bugs transmit infectious diseases even though they appear physically capable of carrying pathogens and this possibility has been investigated. The bite itself may be painful thus resulting in poor sleep and worse work performance. Bed bugs are small, flat insects that feed on the blood of people and animals when they sleep. Their slim flat bodies allow them to fit into the smallest of spaces and stay there for long periods of time, even without a blood meal.

Note that an irritation or bite experienced in bed may not necessarily be due to a bed bug infestation. Bed bugs are one of the great travellers of the world and are readily transported via luggage, clothing, bedding and furniture. They do need to feed on people and may hide in belongings or clothing that allow them to spread to others in group care settings. Look for specks of blood, rusty spots from crushed bugs, or dung spots the size of a pen point on bed sheets and mattresses or behind loose wallpaper.
