How Does Yeast Kill Fleas?

How Yeast Kills Fleas

Fleas are the natural enemy of dogs and cats. They are not a favored houseguest of human owners, either. Getting rid of fleas can sometimes seem like a never-ending battle. Yeast is a simple household remedy that can greatly reduce fleas and repel them. It is safe and effective, and can be used both internally and externally as a flea-eradication or flea-prevention tool. For maximum effectiveness, yeast treatments should be continued throughout the flea season, from early spring to late fall.

How Yeast Works to Fight Fleas

The primary ingredient in yeast that kills and repels fleas is the vitamin thiamine. Thiamine is a member of the B vitamin group and does not kill fleas the way insecticides do. What thiamine does is overpower fleas while at the same time boosting your dog or cat's own immune system.

How Yeast is Given Internally and What It Does

Yeast can be used internally by sprinkling it directly onto your pet's food. By introducing yeast to your pet's diet, it will be ingested by fleas when they bite. Fleas do not like the taste of brewer's yeast, so they are repelled by it, and the thiamine in the yeast kills them.

Amount of Yeast to Feed Your Pet

The proper amount to use on your pet's food is 1mg per 5 lbs. of body weight.

How to Apply Yeast as an External Flea Repellent

Sprinkle brewer's yeast over your pet's coat and rub in thoroughly for an effective flea repellent. Fleas do not like the smell or taste of yeast, so they are less likely to stay on your dog or cat.

Why Use Yeast?

Yeast is much safer than commercial flea products because it is natural and safe for human contact. Even if a child happens to get some on his hands or in his mouth. it is perfectly safe.
