Fowl pest

Imports of biological products into the USA are restricted by the requirement to have the manufacturing facilities licenced and inspected by US inspectors or by local inspectors, if these are recognized by the USA. Furthermore, biological products are subject to a permit for each individual shipment, quarantine for the product and tests by the authorities before release. Veterinary biological product licences will not be issued for products from countries "...known to have exotic diseases, including but not limited to, foot and mouth disease, rinderpest, fowl pest (fowl plague), swine vesicular disease, Newcastle disease, and African swine fewer (9 CFR 104.2). 

The northern fowl mite, Ornithonyssus sylviarum (Arcari Macronyssidae), is an obligatory blood-feeding ectoparasite (hematophagous mite), which is considered to be one of the most important and common pests of poultry. This mite is sensitive to lambda-cyhalothrin, cypermethrin, fenvalerate, and permethrin. Due to short residue time, many registered compounds often need to be repeated after 2-4 weeks. Residue time of an insecticide on feather depends not only on the nature of but also on the formulation of the drug [39].
