safer flea control methods
I stay away from chemicals in flea repellants. Fleas can become resistant to the pesticides, and the flea still has to get on the dog for it to die. I think prevention is the better method. My dogs get 1/4 a clove of garlic and 1 tbsp of brewer's yeast per day, and I have never seen or heard of any problems with gas, and surprisingly, they don't stink either. I think this has to do with their lack of sweat glands.
Dogs do have a natural resistance to fleas, we've just over vaccinated, medicated, fed poor quality dog foods, and stuck "bandaids" over things for so long that these natural resistances they once had have diminished. I believe the answer is to improve the dog's base health so it can fight insects, intestinal parasites, and heartworms on its own. A weak dog is a good target for a parasite. It bothers me that the frontline and other pesticide boxes warn me against touching or inhaling the fumes of their product but it's okay to put it on my pet...it just doesn't seem right. Even if all these claims about harsh chemicals used for flea repellants on pets aren't true, I'm not about to risk it. I just know that I've seen outstanding results by avoiding commercial pet products and chemicals.
Another thing I do that works very well is making my own flea repellant spray. You can spray it around the house, pour it on the dog after a bath, spray it on between baths, and even put it in the rinse load in the washing maching. It's perfectly safe for dogs and I know many people who use it. Just boil one orange or lemon peel for 10mins in 1 pint of water and let it cool. Leave the peel in as you use it. The fleas can't stand the citrus scent, and also there's no nasty pesticide residue on their furr.
Another helpful method is to use natural essential oils. Just put a few drops on a nylon collar once a week and you have a natural flea collar. Neem oil and citronella are good to use for this. You can get them at natural healthfood stores or just type it in google for internet sources to buy from.
Always make sure the sources of fleas are cleaned. Steam clean carpets, and wash all the pets' bedding in hot soapy water and dry on the hottest setting to kill flea eggs. Ants also eat flea eggs and larvae, so if you can stand a few around your yard, don't discourage them.
I like these methods because many have been used for years and years, and it's impossible for fleas to become resistant to a less appealing dog.
