Most fleas do not survive 72 hours on an animal that is itching and able to groom itself. New fleas experience very high mortality on healthy adult hosts. Once a blood meal has been taken, the flea can survive only a short time if it is dislodged from the host. New fleas begin feeding within hours of finding a dog or cat. Emergent fleas are fairly mobile and can survive a few days without a host, if in a suitable environment. Normally, expupation occurs when a host is near and the new flea finds the pet within seconds of emergence. Pupae can lie dormant for many months they are stimulated to expupate as emergent adults by vibration, warming and increased carbon dioxide. Pupae are resistant to freezing, desiccation, and insecticides. Larvae eventually spin cocoons (often within carpet fibers) for pupation. Larvae are susceptible to traditional insecticides, borates and insect growth regulators. Larvae develop in the host's environment and feed on adult flea feces (blood) that fall out of the hair coat of the pet. They are resistant to insecticides, but susceptible to various Insect Growth Regulators.
