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.
