There are several flea and tick control products for your pets. They contain a product called imidicloprid....as omminus as this name sounds it is perfectly safe for use on your pets. A once a month application to the pets neck knap wil kill ticks, fleas and any other sucking critter. Once the pets are clear and clean, the house can be successfully disinfected with any good cleaner. If you don't get the routine down, you will have a bloody forhead....from beating your head against a brick wall. Clean pets, clean house.
PS. There are several, nationaly advertised products, they all contain the same active ingrediant, if you stump your toe, call your veteranarian.
