Fleas are a pest to humans and pets. They are the most common cause of skin disorders for pets in Australia. A single flea bite to a hypersensitive animal or person can cause intense itching and irritation.
Fleas progress through a life cycle from egg, larva, cocoon and finally into an adult flea. In the cocoon stage, a flea may lie dormant for over a year.
Adults are very small, laterally flattened and have a body covered with backwardly projecting spines.
Adults are an active pest; they are mostly found crawling among hair or fur and are able to jump a long distance to another feed. More importantly some fleas are carriers of serious diseases such as murine typus and a number of tapeworm type infections.
