The use of natural enemies for pest control is named biocontrol or integrated pest management. ANDROLIS® are living insects which are commonly associated with the red blood mite in the wild. ANDROLIS® is a noninvasive species since it can be found in all European countries. The use of ANDROLIS® does not present any risk for the environment, the user or the treated animals. No risk due to over dosage. Release systems such as PREVORUS® and our special diffuser bottles are useful to spread the predators slowly in the environment. In case of strong infestation several releases in a short period of time can be needed to eradicate the pest.
