Flea IdentificationAdult bird fleas are generally brownish in colour, and 1/32"-5/16" long. The eyes as well as the antennae are apparent. Their mouth-parts are well adapted for piercing skin and sucking blood and project downwards from the head.
DescriptionAdult bird fleas live in bird nests. When the birds move from the nest, the adult fleas must find a new host. If the nest is reused, the pupae will hatch, mate and continue the breeding cycle. Bird fleas can multiply enormously in hen houses, breeders, batteries etc. Bird fleas can only live for a short time indoors and only in nests. They breed during the nesting period when the host and/or young are available for regular blood meals.
