My wife is very allergic, though the fleas don't bite me and I rarely even know there are some in the house. Is there anyway to make her less of a bite target? Like eating garlic or something? Or is that just vampires?

Why do you have fleas in the house? From an animal?

Best idea is to get rid of the fleas.

Researchers tell us that people attract fleas just as they attract mosquitoes, some are more attractive than others. There aren't any really effective flea repellants that I'm aware of.

Here are some tips I gave another questioner about getting rid of fleas(sorry it's a little long):


Flea Biology 101 - Fleas pupate inside a cocoon just like a moth or butterfly. They do not leave that protected cocoon until it's time to get the blood meal they need to breed and lay eggs. Bombs, sprays, powders, etc. cannot penetrate those cocoons. You need to get the flea to hatch itself out so it can be affected by the pesticide.

Research has shown that there are three main factors in getting the adult flea to hatch out: temperature, humidity, and the vibration or pressure from a potential blood source passing by. As far as temperature and humidity go, guess who likes the same things we do? Yep.

Setting up vibrations in your carpets and rugs can best be accomplished by the beater brush on your vacuum cleaner. The vacuum also sucks up eggs, some of the larvae, and the dirt the larvae feed on.

To keep the ones you vacuum up from surviving, the flea powders for carpets help in a couple of ways: killing fleas and showing you spots that need more vaccuming.

Keep in mind that every couple of days more pupae inside their cocoons will reach maturity, so vaccuming once won't do. Fleas spend an average of two weeks in the pupal stage, so vaccuming daily for at least that long is essential.

Sorry about the book length answer, but if you know why you're doing something you can do it better.

Summary:

Keep the animal treated. With neighbor animals you MUST keep it up.
Treat the home with a product to kill adults and a growth regulator to inhibit maturation.
Sprinkle flea powder liberally on the floors after the spray/bomb has dried.
Vacuum, Vacuum, vacuum, vacuum, vacuum, vacuum, vacuum, vacuum, vacuum (14 times) every day for at least two weeks, maybe three.

Have you used Frontline? Or checked with the vet for a fast treatment for the animals? We had three cats with fleas (one cat passed on the fleas to the other two), and with thorough cleaning and vacuuming, managed to get rid of the fleas over a weekend.
