Dermanyssus gallinae, commonly known as the red poultry mite, is a parasitic mite that primarily infests birds, particularly chickens, but can also bite humans when bird hosts are unavailable. These mites are nocturnal feeders, emerging at night to feed on the blood of their hosts. While they are primarily a problem in poultry farms, they can infest homes near poultry operations or areas with bird nests, leading to skin irritation in humans.
Human exposure to Dermanyssus gallinae bites can cause red, itchy welts and a rash, especially on exposed skin areas. The bites may lead to intense itching and, in some cases, secondary infections if scratched. People working in poultry farms or handling birds are at a higher risk of exposure and may experience ongoing discomfort if infestations are not controlled.
Managing infestations of Dermanyssus gallinae involves thorough cleaning and disinfection of bird coops and living areas, treating birds with mite control measures, and sometimes using insecticides in heavily infested areas. For humans, avoiding close contact with infested birds and using topical treatments to alleviate itching and inflammation can help reduce symptoms. Preventing and controlling poultry mite infestations improves both poultry welfare and human comfort, particularly for those who work with or live near affected birds.
