Avian lice and mites can cause skin irritation, itchiness, powdery and flaky deposits and sometimes scabs. Severe infestation can result in other health issues such as anaemia, reproductive issues and immune system issues. Avian Insect Liquidator was formulated by avian veterinarians to control avian lice (order Phthiraptera, suborder Mallophaga) in ornamental caged birds and their environment. Provides instant knockdown of mites and lice and 6 weeks residual protection of both birds and their environment. Suitable for any situation where external parasites are a problem - including nest boxes, flights, perches, aviary floors, indoor cages and for direct application to the bird.
