A flea pupa while in the cocoon is impervious to treatment and can live for eight months without feeding. Veterinarians are skeptical of homemade flea remedies such as garlic, vinegar, vitamin C and kelp. Call on a professional exterminator for severe indoor and outdoor infestations. Read directions carefully. Never apply a flea product to a cat or kitten unless it is labeled as safe for cats.
Cats are very sensitive to insecticides.
