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>
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.
Both shell thinning and shell spotting can be attributed to the impact of Dermanyssus gallinae
