It is easy to monitor for fleas by watching your pet. If a pet seems to be scratching more often, chances are fleas are the culprit. One way to determine if fleas are infesting your house or pet is to lay a white sheet over your pet’s bedding and watch for jumping fleas. The fleas show up on white surfaces clearly. Another monitoring method is to use a pan of soapy water with a light nearby to attract fleas. The fleas will jump toward the light source, fall into the water and drown. To determine flea location and population size, try wearing a pair of white socks and light coloured pants while walking in a suspected area of infestation. Again, the fleas will be attracted to the white colour and will be seen jumping at the ankles and legs. This method will work best if the pet has been absent from the dwelling for a short time.
