Flea Collars: What to Know Before Purchasing

How Flea Collars Work

  • Imidacloprid/flumethrin is a chemical that is slowly released from the collar to disorient insects enough so that they stop feeding. It’s considered low toxicity for humans (unless it’s ingested). Imidacloprid/flumethrin can reduce flea count by 95%.
  • Deltamethrin is made from chrysanthemum flowers, which are commonly planted in golf courses and ornamental gardens. It’s safe for humans, but highly toxic to fish. Deltamethrin’s effectiveness is about 89% in reducing fleas over a period of eight months.
  • Propoxur is used to fight agricultural, forestry, and household pests, including fleas, moths, and mosquitoes. Propoxur is highly toxic to humans. Propoxur is the least effective-it only reduces flea count by roughly 85%.

Benefits of Flea Collars

  1. Are readily available over the counter (or online) — No medical bills and no prescription needed.
  2. Promote long-term health — Excessive scratching can damage your dog’s skin and could even lead to infections and hair loss and anemia from blood loss.
  3. Can save your home and your yard — Cleanups after an infestation can be timely and expensive. Flea eggs can easily roll off your dog’s body and into your carpet, couch, and even your yard, then hatch and develop for up to 90 days.

Best Ways to Use Flea Collars

  • Active ingredient — Some ingredients that are safe for dogs are not safe for cats. If you have a mixed-pet household, make sure the ingredients are safe for everyone.
  • Lifestyle — Does your dog like to play rough? Do they like to swim or go for walks in the rain? Your collar will need to accommodate your pet’s play style and you might consider getting a waterproof one. Collar efficacy can decrease if it gets wet while bathing, being outside, or even being licked by your other pets. If you know that your dog’s collar has gotten wet, consider buying a new one.
  • Fit — Your dog’s collar should fit snugly around their neck so it can make contact with their skin. You should be able to place two fingers under the collar and any extra length should be cut off and thrown away. Occasionally re-check the fit, especially in growing puppies. The collar will be completely ineffective if it gets too loose or falls off.
  • Special features — Do you need a collar with all the bells and whistles? Some collars only kill fleas, but not ticks, so that’s something to keep in mind. Also, collars may or may not be able to kill eggs and larvae-read carefully.
