Citrus peel extract is an excellent choice against fleas for dogs, because its components—d-limonene and linalool—kill all stages of the flea's life cycle. I have completely eradicated our home and dogs of fleas using citrus peel extract—I don’t think anything else works as well. Still, you must use caution: while it is a natural material, and much safer for health and the environment than toxic synthetic pesticides, it is not without problems, especially for asthmatics (see “Caution,” below). Citrus shouldn't be used around cats.
For Fleas from and on Dogs Assuming you don’t own a cat, and you keep your windows open when using citrus peel extract products, get rid of fleas in your house by washing floors twice a week with a solution of 1/4 cup citrus peel extract (available in health food stores--citra solve is one brand) in 1 to 2 gallons of water. Spray bedding with a mixture of 2 teaspoons citrus peel extract and 2 cups of water in a spray bottle.
To make a fur rub for the dog, cut up 4 lemons, and simmer for one hour in 1 quart of water, adding more water as it evaporates. Cool the mixture, strain, and massage into the dog’s coat. Note that there are a number of pure citrus-peel-based pet products on the market
Most modern synthetic cleaning products are based on age-old formulas using natural ingredients that were passed down through the generations because the chemistry was right. Going back to the original naturally-derived ingredients is a way to make cleaning products that work, don’t pollute, and save you money. Most are found in your kitchen cupboards. Mix and match with well-chosen and environmentally-friendly green cleaning products found in health food stores, and you can easily and simply transform your home into a nontoxic and healthy haven.
Learning to clean from scratch—making home-made recipes—can truly work if you take time to understand a bit about the chemistry behind how the materials work. Here are the five ingredients that I find to be the safest, most effective, and useful for cleaning.
