Although most fleas are found to affect cats and dogs however they can still be a disturbance to humans.
Fleas can be carried in by pets, people and second-hand furniture etc. Most fleas require warm conditions i.e. wall to wall carpeting with hiding places and central heating as it provides warmth all year. Fleas lay their eggs on carpets and fabrics, when conditions are warm and favourable then these eggs will hatch into adults, this usually takes roughly two weeks however these eggs can lie dormant for up to 18 months.
Flea Bites may be seen in clusters, with cat and dog fleas being seen mainly below the knee, more commonly around the ankles. Whilst they are not life threatening, these bites can be irritating and if there is continued scratching which is not treated, can fester into infections.
