Human ectoparasites
Arthropods
Bedbugs
Begbugs are "bugs of the family Cimicidae, genus Cimex. They are flattened, oval, reddish insects which inhabit houses, wallpaper, furniture, and beds. C. lectularius, of temperate regions, is the common bedbug that attacks humans and is frequently a serious pest in houses, hotels, barracks, and other living quarters. Experiments have shown that bedbugs can transmit a variety of diseases, but they are not normal vectors under natural conditions."[1][2]
In 2005, bedbugs were reported in North America.[3] Bedbugs have been reported that are resistant to deltamethrin.[4]
Fleas
Fleas are "parasitic, blood-sucking, wingless insects comprising the order Siphonaptera."[5]
Lice
Lice are "A general name for small, wingless, parasitic insects, previously of the order Phthiraptera. Though exact taxonomy is still controversial, they can be grouped in the orders Anoplura (sucking lice), Mallophaga (biting lice), and Rhynchophthirina (elephant-lice)."[6]
Pediculosis are 'lice of the genus Pediculus, family Pediculidae. Pediculus humanus corporus is the human body louse and Pediculus humanus capitis is the human head louse."[7]
Mites
Chiggers (Trombiculidae)
Chiggers are "a family of mites in the superfamily Trombiculoidea, suborder Prostigmata, which attack humans and other vertebrates, causing dermatitis and severe allergic reactions. Chiggers, red bugs, and harvest mites commonly refer to the larval stage of Trombiculid mites, the only parasitic stage of the mite's life cycle."[8]
Scabies
Scabies are "a contagious cutaneous inflammation caused by the bite of the mite Sarcoptes Scabiei. It is characterized by pruritic papular eruptions and burrows and affects primarily the axillae, elbows, wrists, and genitalia, although it can spread to cover the entire body."[9][10]
Regarding treatment, "Topical permethrin appears to be the most effective treatment for scabies" according to a meta-analysis by the Cochrane Collaboration. [11]

Ticks
