If you own a dog or cat, it is almost certain at one time or another that you will have to deal with fleas.

And that’s where the trouble begins – not just with the fleas themselves, but with the vast array of commercial flea control products available. Ironically, the majority of these products, even the most popular ones, contain unsafe, harmful ingredients. Often these ingredients are toxic to the very animals they are supposed to protect – and can even do harm to you and your family. The National Resource Defense Council’s website for pet owners, www.greenpaws.org, offers a comprehensive list of commercial flea and tick products, their ingredients, and whether they are safe. You’ll be surprised to learn that most of them contain harmful chemicals.

The most popular treatments require expensive monthly applications during flea season, for the life of your pet. Frontline Plus, for example, can cost from $10 – 15 for each application. This means flea control can become costly, very quickly.

What’s the alternative? Natural Flea Control!

Natural flea control uses natural techniques and substances in the fight against fleas. In most cases, you will find that natural substances are commonly available and, as a result, are much cheaper than commercial products. Natural substances are often far less toxic as well. It’s important to point out, however, that “natural” doesn’t always mean safe.

Here is an example. Natural substances effective for flea control include “essential oils,” which are botanical compounds in highly concentrated form. One of these essential oils, pennyroyal, has been proven effective in flea control – but pennyroyal is toxic when applied to the skin of a dog or cat. In fact, it can be deadly if ingested. Since animals commonly lick themselves when they have fleas, they could lick the pennyroyal with dire consequences. You might make the assumption that pennyroyal is safe because it is a “natural” oil. You would be dead wrong. That’s why you need to carefully evaluate any natural flea control substances before you use them on your pet.

Frontline and Frontline Plus are among the most popular topical flea control products. Yet over and over again on discussion boards and in forums, you see comments from dog and cat owners claiming that Frontline isn’t working.

Commercial topical products such as Frontline, Advantage, K9 Advantix, and Revolution are, of course, formulated to control fleas. Each of them contains different chemicals, many of which are hazardous. (See the post about dangerous chemicals.) Some of these chemicals may be more effective than others in flea control.

A flea is a very resilient creature — difficult to control because it reproduces so rapidly, and difficult to kill because of its bodily structure. Can a flea build up a resistance to chemicals such as fipronil, a key ingredient in Frontline? Quite possibly. Evidence exists that insects can become immune to certain chemicals over time.

If you are using a commercial topical product like Frontline, be sure you are following the manufacturer’s application instructions precisely. If you suspect it is not controlling your pet’s fleas, you may, in certain cases, be able to reapply it in as little as two weeks and try again. Speak to your veterinarian about this first.

One alternative is to switch to another topical product. Another alternative is to supplement the topical product with another product that works internally, such as Capstar.

Based on the research conducted for our Flea Control book, however, we believe the best alternative is a natural one. We think it is safer and more effective to switch from commercial products with potentially unsafe chemical ingredients to natural products — products that nature designed to control fleas. For example, using predatory nematodes in your garden is one way to control fleas naturally outside your home. A way to control fleas naturally inside your home is to apply diatomaceous earth or salt to your carpet. A way to control fleas naturally on your pet is to use neem oil.

These natural substances have been proven effective for controlling fleas for a long time — longer than the chemicals that are used in most commercial flea control products. The natural substances mentioned here are just a few alternatives to chemical products — you’ll find others in the Flea Control book.

There are many commercial products available to prevent, control, and kill fleas, but the majority of these products contain unsafe, harmful ingredients. In fact, most commercially available pesticides contain toxic chemicals. Often these ingredients are toxic to the very animals they are supposed to protect – and can even do harm to you and your family.

According to the Natural Resources Defense Council (NRDC): “Many Americans believe that commercially available pesticides, such as those found in pet products, are tightly regulated by the government. In fact, they are not. Many of the products sold in grocery, drug and pet supply stores, even when applied as instructed on the box, can cause serious health consequences to pets and humans. Just because these products are on store shelves does not mean they are safe.”

The EPA did ban six types of organophosphates from the pet products market because they were found to be extremely harmful to pets and children. The banned substances are: chlorpyrifos, dichlorvos, phosmet, naled, diazinon, and malathion. One organophosphate has not yet been banned: tetrachlorvinphos (TCVP). Be certain you avoid pet products with any of these ingredients. Carbamates, another dangerous class of chemicals, should also be avoided.

The NRDC offers the following advice:

Products with the following chemicals should be avoided:

Amitraz, fenoxycarb, propoxur, and tetrachlorvinphos (TCVP)

Products with the following chemicals should be used sparingly:

Fipronil, imidacloprid, metaflumizone, pyrethrins, selamectin

Products with the following chemicals are considered generally safer:

Lufenuron, nitenpyram, pyriproxyfen, s-methoprene, spinosad

Note that cats are particularly sensitive to the adverse effects of pyrethrins and pyrethroids (synthetic versions of pyrethrins). If products with these ingredients are used on dogs with cats in the home, cats can still be exposed to toxicity.

If you are planning to use ANY flea control product, it is advisable to read the label not just for warnings, but for a list of ingredients. Refer to the NRDC’s website, http://www.greenpaws.org, for detailed information about pet products with harmful chemicals.

Diatomaceous earth, sometimes referred to as “DE,” is a natural substance that is actually created from the remains of diatoms, microscopic water plants that are like algae. It contains such minerals as silicon, calcium, sodium, and magnesium. It has a consistency similar to talcum powder and is available at most garden suppliers.

This is a remarkable substance that is a desiccant – it actually dries out the waxy outer layer of fleas so they dehydrate and eventually die. As an added benefit, diatomaceous earth can eliminate other insects.

So yes, in some respects, it is a miracle cure for fleas.

But even though diatomaceous earth is a natural substance, its dust is dangerous to breathe for both humans and animals. Using it requires gloves and a dust mask. Be certain to read any cautions that come with the product and use it only as directed.

Outside the home, spread it around the foundation and entry points. Inside the home, spread it around windows, doorways, and baseboards and rub it into the carpet. If you use this method, always use gloves, a dust mask, and goggles, and leave the house for several hours after use. It is not safe to inhale this substance when any particles are floating in the air. Fish, birds, and animals should not be left in the house. When you return, vacuum thoroughly.

Some people spread diatomaceous earth directly on their pets, essentially using it as a flea powder. If you do this, be aware of the potential risks. Since it is a drying agent, diatomaceous earth can dry out your pet’s skin. It can also be irritating to the eyes and lungs. Make sure you are using “food grade” diatomaceous earth if you want to try it on your pet.

Watch the accompanying video for an interesting if lengthy explanation of diatomaceous earth.

Diatomaceous earth is one of the natural substances discussed in Flea Control: How to Get Rid of Fleas Naturally.
