If your four-legged friend is hounded by fleas in spite of treatment, it’s time to go over your flea control plan with a fine-toothed comb.

Resistance isn’t a problem with the newest flea products. Instead, the number one reason for stubborn flea infestations is incorrect use of products by pet parents.

Many over-the-counter products were developed decades ago and knock out only a small portion of your pet’s fleas. Newer products kill almost all fleas on your pet within one day and get rid of both adult fleas and eggs. All furry pets in your household should be treated with a pet-safe product. Even if you can’t see fleas, routinely treat your pets as directed by your veterinarian. And remember that any flea control program includes treating your house and yard too.

A little scratching beneath the surface can boost the fight against fleas.
