Fleas can be pests in homes, hotels, motels and wherever human populations occur in areas shared with animals. They all have piercing and sucking mouth parts used to draw blood from their host. They can transmit diseases to other humans and animals, and are therefore seen as important pests both in the medical and veterinary areas. Adult fleas vary in size, but are typically 1-2 mm long, brown in colour and have compressed laterally bodies (meaning very thin) so that they can move freely between the hairs of their animal hosts.
Control measures for fleas include liquid residual insecticide sprays, insecticidal dusts, granular insecticides, flea traps and specialised aerosol formulations.
