Protected by this cocoon, the flea is impervious to insecticides and can wait many weeks for a host to come near. When the flea senses vibration from footsteps, it pops out, looks around and immediately takes a leap. You can spray all you want, but fleas will continue to emerge from their cocoons for about three weeks.
You can vacuum and spray as much as you like, but expect to see some fleas for 2 weeks or longer following treatment.

They feed off the blood of humans and animals such as dogs and cats. Since fleas use a wide range of hosts, diseases can be transferred from one host to another. Fleas are known to transmit tapeworm larvae and, uncommonly, the disease murine typhus and most notoriously bubonic plague. There are three main species of flea that infest humans:
Cat flea (Ctenocephalides felis)
Dog flea (Ctenocephalides canis)
Human flea (Pulex irritans).
Adult fleas can survive for some months without feeding. The flea uses its saw-like mandibles (jaws) to cut through skin, usually on accessible parts of the body such as the legs or feet. Flea saliva contains anticoagulants to encourage the blood to keep flowing. Female fleas are prompted to lay their eggs after feeding. The eggs are light coloured and oval-shaped. The larvae cocoon themselves within weeks of hatching. As I said above, vibration, such as footsteps, prompts adult fleas to emerge from their cocoons. This is why you may be bitten after entering a house that has been unoccupied for some time.

If your pets do have fleas it can be never ending sometimes. If you put flea powder on pet then the fleas that are still in carpet will just jump straight back onto pet. Best to thoroughly powder carpet and pets. But if you're saying they dont then just tell them they must still have them in their flat from last year and to clean their carpets.
