Fleas range from about 1–5 mm in size (usually around 3 mm). Their bodies are flat, shiny and have a tough surface. These features mean the flea can move through the hair of their hosts without being dislodged.
Several species are found on a range of warm-blooded hosts, including humans (eg, the cat flea, the dog flea, the bird flea, and the northern rat flea). Adult fleas are found on the hosts themselves, whereas the larvae and pupae live in places like the burrows or nests of hosts.
When fleas have not fed for some time they are likely to be less specific about their choice of host and this may involve having a human blood meal. While the human flea is rare in New Zealand, cat and bird fleas are very common.
