Dermanyssus gallinae (also known as the red mite, poultry mite, red poultry mite and chicken mite) is an ectoparasite of poultry and other bird species.



The mites are blood feeders and attack resting birds at night. They are generally white or greyish in colour, becoming darker or redder when engorged with blood. After feeding, they hide in cracks and crevices away from daylight, where they mate and lay eggs. The mite progresses through 5 life stages: egg, larva, protonymph, deutonymph and adult. Under favourable conditions this life cycle can be completed within seven days, so populations can grow rapidly - causing anaemia in badly affected flocks of poultry. Young birds are most susceptible. The mites can also affect the health of the birds indirectly, as they may serve as vectors for diseases such as Salmonellosis, avian spirochaetosis and Erysipelothrix rhusiopathiae.[1]

Dermansyssus gallinae can also feed on some species of mammals, including humans,[2][3][4] - causing dermatitis and skin lesions. However the mite needs an avian host to reproduce.

Clinical signs and diagnosis

The mites normally feed around the breast and legs of hens, causing pain, irritation, and a decrease in egg production. Pustules, scabs, hyperpigmentation and feather loss may develop.

If they are present in large numbers, D. gallinae can cause anaemia in hens which presents as pallor of the comb and wattle.

A presumptive diagnosis can be made in flocks of laying hens, usually based on a history of decreasing egg production, anaemia and mortalities in young or ill birds. Definitive diagnosis is only achieved following identification of eggs, faeces or the mites themselves

Treatment and prevention

Ectoparasiticides can be used to treat affected poultry. These chemical controls, if used, should be used in rotation to avoid the build up of resistance. Red mites can survive for up to 10 months in an empty hen house. Creosote treatment of wood will kill mites.
