Birds are commonly affected by lice and mites which attack their legs and feathers. Several insecticides are available for painting the undersides of the perches. These insecticides are very poisonous and should be used strictly according to the instructions on the label. Painted on the undersides of the perches, the insecticide fumes rise and penetrate the birds' feathers, killing any lice.
Other effective methods of controlling vermin are to spray or paint perches and cages with kerosene or an insecticide such as Malathion. Birds should be removed from the cages or aviaries during this procedure and not returned to the cages for two or three days. The cages should be rinsed with water after the insecticide has had time to work.
