Fleas

Fleas found in properties will normally be cat fleas
or dog fleas as human fleas are rare now except
in third-world countries.

Pet fleas can be brought in by the pets, people,
second-hand carpets etc. Adult fleas may feed
on different animals but flea larvae require the sort of conditions offered by wall-to-wall carpeting (hiding places) and central heating (warmth all year). Flea eggs are laid on carpets or fabrics. The flea eggs hatch into larvae that then pupate. They can wait dormant before emerging as adult fleas. If conditions are favourable e.g. vibration and warmth, they will hatch into adults fleas This takes about 2 weeks in mild weather. Flea eggs can lie dormant for up to 18 months, usually in empty properties.

Flea Bites may be seen in clusters, with cat fleas and dog fleas being seen mainly below the knee, more commonly around the ankles.
