Many of us prefer to totally avoid the use of toxins in our home, and particularly on our pets. Fortunately, there are many natural flea control methods available

The first thing to realize about natural flea control remedies, is that just because something is natural, does not mean it’s not toxic. Pyrethrins, insecticides derived from the African chrysanthemum, are both natural and toxic.

Essential oils

Although many cat owners use natural flea control remedies that contain essential oils, it is advisable to use caution.

Good nutrition and flea control

Feeding your pet good quality food is not just the right thing to do, it can also provide better protection against fleas. Poor nutrition can make your pet more susceptible to fleas, since a healthy animal is less appealing to adult fleas. Ask your vet for recommendations.

Brewer’s Yeast

Brewer’s yeast can be used for both dogs and cats. Use about one teaspoon for cats and small dogs, and about a tablespoon for a fifty pound dog. If your pet develops a skin rash, they may be allergic to yeast


Thoroughly combing your cat or dog with a flea comb is one of the cheapest and most effective ways to control fleas. Regular baths for your pet are as well. In most cases, plain soap will suffice, and there’s no need to use chemical flea shampoos.

Flea traps

A simple way to trap adult fleas is by placing a light next to where your pet sleeps. Then, under the light, put dish of soapy water. The fleas will be attracted by the light and drown in the soapy water. You can even build your own flea trap very easily.

This method only works for adult fleas, but if it’s done consistently, it can be remarkably effective.
