Protect Your Pets from Fleas

Anyone who owns a cat or a dog must deal with fleas. They not only make your pets miserable, they bite people, too, causing annoying itchy bumps.

Fleas prefer warm, humid conditions, which means they are seasonal in cold climates but are a problem all year round in the Southeast and Southwest. Dogs bring fleas into the house from outside, but even if you only have indoor cats, be on the lookout for fleas. People can track the eggs in on their shoes.

Natural flea prevention is the safest method (see last month’s article “All Natural Flea Control for Pets” by Stacy Mantle), but sometimes stronger measures are required. If you have a persistent flea problem, ask your veterinarian for advice. Consider the people as well as the pets in your household when choosing flea products—if you live with a pregnant woman or small children, topicals—the spot-on medications that you apply between your pet’s shoulder blades— might not be the best choice. Although topicals kill fleas for a month, it can take a few days for all the fleas to die. In addition, in some areas fleas have evolved to be resistant to certain types of topicals.

If you use topicals on your cat, make sure you are using a product formulated specifically for cats. Many topicals for dogs contain permethrin, which is fatal to cats.

Oral flea medications are an option that will not impact others in your household. Capstar kills all fleas within 30 minutes or so, but has no residual effect. Spinosad (sold as Comfortis) is a fast-acting neurotoxin that can have serious side effects in some animals but is very effective at killing fleas for an entire month. Both medications are approved for cats and dogs.

Sometimes it is worth the risk of side effects to use these strong oral medications. One of my cats is severely allergic to flea bites. He scratches them so hard that he wears off the fur and skin on his neck and face. He has had to take several rounds of antibiotics for skin infections. I finally broke down and gave him spinosad, which he tolerates well, and it has kept him flea-free.

Remember that for every flea you find on your dog or cat, there are dozens more in your home. Here are a few measures you can take to minimize the flea activity in and around your house:

• Feed your pets a high-quality diet. The healthier your dog or cat is, the easier it will be for him to resist a flea infestation.
• Bathe your dog regularly with a mild shampoo. If your cat will cooperate (or at least not attempt to eviscerate you), wash him as well, but less often.
• Use a flea comb on your pets every couple of days during flea season. Drop the fleas in a cup of water with a few drops of dish detergent in it—this will cause them to sink and drown.
• Wash all pet bedding regularly. Also wash blankets, pillows and rugs where your pets spend time.
• Vacuum regularly and thoroughly, and not just your floors. Fleas also lay eggs on upholstery and curtains. If you have sofas with slipcovers, you can de-flea them easily by simply throwing the covers in the wash.
• Keep your pets’ claws clipped. That way, even if they do get a few fleas and scratch, they will do less damage to their skin.
• Spread beneficial nematodes on your lawn and gardens. They are available at garden stores and some pet supply stores. They not only kill fleas, but many other pests as well.
