Dermanyssus gallinae is an acari common on poultry animals and their nesting places. It is found on nearly every poultry farm in the world*1, feeds on the blood of host animals and has drastic economic impacts.
They are commonly known as red mites and feed in 1-2 hours. Afterwards they leave the host animal and hide in cracks and crevices. Therefore they are very difficult to detect. They have a very short life cycle, expanding their population fast.
They have direct economic impacts amounting to €0.60 per hen per year *2. These are due to reduction in egg production, drop in egg quality, reduced feed efficiency. Red mites are disease vectors for salmonella, fowl cholera, chicken typhoid, fowl pox, Newcastle disease and more. They also cause anemia, cannibalistic feather pecking, irritation and stress.
