An Infestation of Epidemic Proportions

Infestations of Poultry Red Mites are extremely high and increasing in Europe. Overall infestation rates in European layer houses are now averaging 83%.1

infestation rate

Infestations are damaging to the flocks themselves, as well as economically. Studies have shown productivity losses can be as high as €0.57 per hen per year in case of moderate mite infestation and up to €2.50 in high infestations.2 The approximate annual cost of red mite infestations are at least €360 million in Europe alone, with more than 300 million hens impacted by mite infestations. 3

Current control methods don’t have the efficacy needed to keep mite infestations at bay, leaving many farms, flocks and workers at risk.
