Owning a pet increases the risk of a flea infestation, but it is not only pet-owners who are at risk. Fleas can enter the home on any fabric or fur. Once in the home, their quick breeding cycle means they can rapidly become a nuisance.

This article covers everything you need to know about fleabites, including how to identify and treat them.
