Some flea control products are available without an examination; others are by prescription and require an examination (and sometimes a blood test) before we can dispense them. We recommend parasite control throughout the year, as flea eggs in the house can hatch at any time. We also have a premise spray, Knockout, available for use on carpets and upholstery in your house. When all else fails, we recommend a visit from Flea Busters, who will guarantee a flea-free environment when they are done. Fleas transmit parasites and bacterial diseases; they need to be eradicated from your pet.
