10 Ways to Stop Fleas from Biting Your Cat

There are lots of reason to celebrate the arrival of spring and summer, but the return of fleas is not one of them. Not only are these blood-sucking parasites unsightly and creepy, they can also cause some serious diseases. So, how can you keep your cat flea-free this season? Here are a few ideas to consider:

While spot-on medications seem like they would only work on the spot they are applied to (in the same way a collar works), they are actually very effective at covering the cat’s entire body. The drops work by a process of translocation, by which the medication is spread over the body by way of the oil glands, and by the cat’s natural habit of cleaning itself (i.e., wetting its paws to clean its fur). Spot-on medications are not affected by bathing, swimming, or rain, and will kill and repel fleas for several weeks before reapplication.

Bathing your cat with a special medicated shampoo that kills fleas and/or ticks on contact can be an inexpensive (though labor-intensive) method of protecting your cat during flea season, or year round. You will need to repeat the process more often, about every two weeks, as the effective ingredients in these shampoos don’t last as long as a spot-on or oral medication.

Another option is to use a collar that repels and kill fleas. Their effectiveness may depend on how invasive the fleas are in your cat’s environment, and the collar needs to make contact with your cat’s skin in order to transfer the chemicals onto the fur and skin. When adjusting the collar around your cat’s neck, make sure there is just enough room to fit two fingers under the collar. Cut off any excess length of collar to prevent your cat from chewing on it, and watch for signs of discomfort (e.g., excessive scratching) in case an allergic reaction to the collar occurs. Make sure you read labels carefully when choosing a collar to make sure it is size and age appropriate; this is especially when choosing a collar for cats. If your cat is particularly active or goes outdoors, you should avoid any kind of collar that does not have a quick release latch, since cats are prone to getting collars caught on fences and other objects and suffering choking injuries as a result.

A dip is a concentrated chemical that needs to be diluted in water and applied to the cat’s fur with a sponge, or poured over the back. This is not like a shampoo bath, so you will not rinse your pet off after applying the dip product. These chemical products can be very potent. Misuse can lead to toxic reactions, in both cats and in the people treating them, so they are generally only used for severe infestations, and only infrequently. Make sure to read the labels carefully before use to make sure that it is appropriate for your cat and to make sure that you apply it exactly as stated.

Flea powders and sprays are relatively inexpensive methods of repelling fleas for cats. Be cautious when applying these products, however, as the spray or fine powder can be irritating to the mouth and lungs if breathed in (for both animals and humans). Also be sure to use caution around the eyes, nose, and mouth. Because these products will wear off the skin faster than a spot-on treatment, you will need to reapply them more often. Always read labels carefully before using flea powders or sprays.

For any level of flea infestation, light or severe, you will need to do a thorough house cleaning, and you will need to clean daily until the situation is under control. Vacuum in every corner and along the baseboards, and throw out the vacuum bag when you are finished. Wash all of your cat’s bedding and toys with warm soapy water and vacuum out the car too. Removing the majority of flea eggs and larvae present will help reduce the population of adults hatching in your home.

Sprays and foggers will kill the adult fleas as well as the larvae and eggs as they hatch. Care must be taken when using these products, however, as they can be toxic to fish, birds, cats and children. Read labels carefully and ask for advice from your veterinarian before attempting to use these products. To be safe, you may need to remove all of the animals from your home for 48 hours (or more), so that the pesticide chemicals from the spray or fogger has a chance to dissipate. In the face of a severe infestation, you may want to hire a professional exterminator to spray the house properly.

You can purchase ready-made "flea traps" from your local hardware store, or you can make your own. Sticky pads (some with lights attached) are laid on the floor, where the fleas become attached to the sheet while jumping around. This will help eliminate some of the adult fleas from the environment, but not the eggs or larvae. A homemade light trap can be made by setting a small dish of soapy water on the ground near a light source at night (such as a small lamp or night light). Fleas are attracted to the warmth and light and will jump into the water, where they will drown.

Keeping your lawn, bushes, and trees consistently trimmed back will help reduce the population of fleas in your backyard. If you still have a problem, consider using one or more of the various yard sprays or granular treatments. Or, you might consider hiring a pest control service for regular yard treatments. Just be careful when using these products, as they can be harmful to pets, fish, and humans (you may want to warn your neighbors before each yard application so they can protect themselves from incidental contact with the chemicals).

For light infestations, a simple lukewarm bath will often take care of the fleas that are on the body (yes, even for cats). The water and soap are enough to get rid of the fleas, and if used along with a flea comb, the situation can be brought under control with little fuss. This must be followed up by a thorough house cleaning and another method of repelling the fleas (see above solutions); otherwise the fleas that are hiding in the floor and furniture will jump back onto your cat.
