Fleas are the most common external parasite of companion animals.

Flea control has always been a challenge for veterinarians and pet owners because the adult fleas cause clinical signs, yet the majority of the flea population (eggs, larvae and pupae) are found off the pet in and around the home.  Fleas are picked up from the environment or from other animals.  The adult flea goes on your pet to feed.  Once the flea has a blood meal they lay eggs.  An adult female lays about 20-30 eggs/day and can survive on the pet for up to 2 months.

These eggs then fall off into the environment - carpet, sofas, etc.  Depending upon temperature and humidity, these eggs hatch and develop through several stages to adult fleas.  This can take from several days to several months depending upon the environmental conditions.  This allows the flea to survive for long periods in your house as well as through winter at a cottage.

Flea allergy dermatitis is one of the most common diseases of dogs and cats.  When a flea bites your pet it injects some chemicals to keep the blood flowing.  In most dogs and animals this causes a localized itch when the flea is biting.  However, in some animals these chemicals severely stimulate the immune system and cause 'flea allergy dermatitis'.  The signs of flea allergy dermatitis are extreme itching to the point of causing damage to the skin.  There is often hair loss and scabs especially just in front of the tail.  Treatment of flea allergy dermatitis requires both control of the fleas as well as medication to deal with the allergy.
