Bugs

Parasites belonging to the hexapods (insects). Only the species of the family Cimicidae have specialized as hematogenic ectoparasites of birds and mammals as well as of humans. This family is represented worldwide with 22 genera and 74 species. Cimex lectularis (common bedbug) is a parasite specialized exclusively for humans.

Bedbugs are nocturnal animals and infest their host while sleeping. During the day they linger in cracks and crevices of sleeping rooms. On human skin the parasite looks for a suitable place for the sting and stays for the sucking act usually 3-5 minutes at the sting site. The sting of the bug is not primarily noticed by an anaesthetic liquid in the saliva. Itching also occurs a few hours later. The pigeon bug parasitizes chickens and pigeons. Bats are attacked by the bat bug. All these species can also sting humans.

• Local stab reactions (see below cimicosis).
• Transmission of various pathogens such as Coxiella burnetii and possibly hepatitis B viruses.
• As a cause of allergic-asthmatic complaints in case of intensive contact, e.g. with collectors and breeders.
