Cat flea, usually brown to black in colour, is a small insect that measures at 1 to 2mm long. Their flat bodies make them incredibly hard to spot in a cat’s fur coat because of how thin these insects are. The cat flea’s primary hosts are domestic cats and kittens. The female of the species will lay her eggs on the host, and these eggs will then be transferred from the host to the host’s surrounding environment. The fleas also have three pairs of legs, designed for jumping from one cat to another or even to a human being. Fleas are renowned for their jumping abilities; therefore, the first sign of a bad infestation indoors will always manifest as bites on a person’s leg within the region of the ankle. 
5 DIY Steps to Solve Your Flea Issues, and 1 Step for the Professionals
- First, all cats and kittens in your home should be treated for fleas by a qualified veterinary surgeon.
- Warm wash all beddings, fabric fittings, cushion covers and curtains thoroughly. Vacuum the mattresses, sofa sets, cushions and all fabric furniture, particularly under the cushions and the crevices where the eggs might be.
- Vacuum all carpets daily, and remember to dispose of used vacuum bags.
- Steam-clean carpeting and fabric fittings. This will eliminate any remaining eggs laid by the fleas.
- It is necessary to put all your fabric furniture, such as sofas, armchairs and footstools, in direct sunlight for at least 2 to 3 hours.
- Hire a professional pest controller to treat the indoor areas. Insist on a “safe & friendly” product for this purpose. However, please note that this step should be accompanied by all the other steps stated above. The flea treatment should be done after the other steps have been carried out.
