Fleas like warmer climates, but as homes and buildings become better heated and insulated they are becoming more prevalent in cooler climates. Commonly found in vacated premises which have previously contained domestic pets or animals. They occur periodically in dwellings where pets are kept inside or other animals frequent outside. They occur in buildings where there is high foot traffic e.g. banks, hospitals, and hotels, and occasionally get bought into the premises by people or their belongings.

Fleas are almost impossible to detect as eggs or larvae and usually only noticed in adult form. Try using a white sheet on the floor or the bed to properly identify the problem (you may see them jumping against the white background).

They are one of the more important groups of insect pests because they not only cause itching and discomfort by biting, but they can transmit several diseases such as plague and murine typhus.
