Where do fleas and ticks live?

You may not see them, but they're there.

Fleas and ticks can be nestled in hiding places inside and out without you ever knowing it. See below for some of their more common hideouts:

  • On other pets and animals
  • Around shrubbery and bushes in your backyard where other infested animals frequent

In addition, developing stages of fleas may be lurking out of sight:

  • In carpets, floors and sofas of your home

That's why you need flea & tick protection like FRONTLINE brand products that can attack fleas and ticks on your pet. Anything less just won't do.

The flea life cycle—break it, or else.

Flea infestations start with just 2 fleas laying hundreds of flea eggs within a matter of days.1 FRONTLINE brand products prevents an infestation by not only killing adult fleas—which comprise only 5% of the total flea population—but also by killing flea eggs and larvae too.1

This diagram demonstrates the 4 main stages of the common flea life cycle including flea eggs, larvae, pupae and adult fleas.1

Flea bites can lead to diseases.

These nibbles start out as a simple itch but can lead to a wide range of diseases or other parasites, including:

  • Flea Allergy Dermatitis (FAD)3
  • Anemia3
  • Tapeworm4
  • Rickettsiosis5

These conditions can deprive your pet of energy, cause skin problems or adversely affect your pet’s health in a number of ways.

Other Flea and Tick Protection Tips

To keep your pet even more protected, take aim at fleas and ticks in and around your home. Here are a few tips:

  • Periodically, wash your pet’s bed cover in hot water and dry it on a high heat setting to kill any flea eggs and larvae
  • Make your yard less appealing to ticks by cutting grass short and eliminating brush piles
  • Vacuum frequently in your home, especially carpets where your pet tends to lounge
  • Cover up all outside crawl spaces and garbage cans to deter wildlife that may carry fleas and ticks
