How to Get Rid of Fleas - as part of the expert series by GeoBeats. The number one problem with flea products, when a person goes to the store is they want to get as little as possible to take care of the flea problem. And that is problematic at best because you are going to have to deal with more… The flea world is more complex. I will just be honest with you. So, sometimes, you know, years ago people would come in and buy a tube or a little container, a six ounce container of diatomaceous earth because it kills fleas. And it does kill fleas. It kills fleas very well, as well as other, you know, cutworms and different little bugs in your environment. And they would come back, maybe a couple weeks later, and say, “This product did not work.” It is like, “Well, okay. Let’s look at the big picture now,” because remember, holistic means all the parts that equal the whole. So we have to concern ourselves with the environment. If it is true, as one of the popular numbers go, for every flea you find on your dog or your cat, there is 200 in your carpet, ok, it is going to take more than one little thing to kill all those fleas. So, we are going to have to deal with all of the environment, not just the carpet. One time I used our boric acid powder on the carpet at my home, and I went into the bathroom that night, which is linoleum, and I got a flea bite because the fleas vacated the carpet and went to the linoleum in the bathroom and the kitchen, and then down to the concrete in the garage. So, the best thing to do is put boric acid powder on the carpet, and then diatomaceous earth or pyrethrin powder on all the other surfaces, whether it is hardwood or linoleum or concrete, so that every time a flea jumps he is going to land in some kind of dust. Diatomaceous earth is a desiccant, so it is just going to dry him out. There is no potency at all. In fact, one time I used diatomaceous earth in my garden because for some reason my garden had a lot of fleas in it. I just got a metal sifter thing and put diatomaceous earth, and I just sifted the whole garden area. It looked like white when I was finished, but that took care of the flea problem out there. So, even when diatomaceous earth gets wet and then it dries again, it is still effective. As long as the diatomaceous earth is there, it is effective.
