The Red Mite Epidemic

Recent surveys have confirmed the extremely high and increasing prevalence of infestations with poultry red mites in Europe. In fact, the average overall infestation rate of European layer houses is 83 percent.1

Mite infestations cause major physiological and economical damages. According to studies by a layer industry expert, productivity losses can reach €0.57 per hen per year in case of moderate mite infestation and up to €2.50 in high infestations.2 In Europe alone, the approximate total annual cost of red mite infestations totals €360 million, with more than 300 million hens in all production types suffering from infestations.3

Current management methods lack sufficient efficacy to keep mite infestations under control at many poultry farms and often pose safety threats for both birds and humans.

The fight against red mites.

Poultry red mites are difficult to control, and infestations grow rapidly.
Many solutions have been developed in recent years, including chemical
control, biological compounds, heat treatments and more.
