Diagnosis is usually done inspecting the vents of the birds for presence of mites and subsequent examination of the mites under microscope.
Dusting with louse powder will control the louse and you need to pull out any feathers with eggs on – a quick tug will do it – and then dispose of the feathers and eggs safely, because if you just chuck them on the ground they will hatch and jump onto the next passing chicken. Nymphs suck blood and after various molts they become adults in about 4 to 5 days. Nevertheless they can be useful to monitor the mite population. The most relevant species are: A parasitic egg count may be done on the faeces, but treatment for helminths may be instigated immediately with cnemifocoptes only licensed product, flubendazole Flubenvet: In this case another product should be tried, ensuring that it has a different mode of action than the one that failed.

Globally, the red fowl mite is the most frequent and damaging species, among other reasons because resistance to acaricides is very frequent, which makes it particularly difficult to control.
Occasionally it can also attack humans, and there is new evidence that it can complete its life-cycle on humans as well.
The red fowl mite also called red poultry miteroost mitechicken miteetc. There are a number of important species infecting both production birds and pet animals.
