Do Flea Collars Get Rid of Fleas on Cats?

A lot of pet parents ask themselves this question, and the answer isn’t always cut and dry. Flea collars can be effective at repelling and killing fleas, but not all of them are equally effective. Also, because each cat is different, they don’t work for everyone.

There are a few things you need to take into account when deciding if a flea collar is the right choice for your cat.

The 3 Questions to Ask if You’re Considering a Flea Collar for Your Cat

1. How bad is your flea problem?

If you only have a few fleas, a collar might be enough to get rid of them. But if you have a heavy infestation, you’ll need to use other methods in addition to the collar.


2. How will your cat react to the flea collar?

Some cats are very sensitive to the chemicals in the collar and can react to them. Others simply don’t like wearing them and will try to take them off. If your cat falls into either of these categories, a flea collar is certainly not the right choice.


3. How often are you willing to put the flea collar on and take it off?

Flea collars need to be replaced every few months, and some pet parents find this to be a hassle. If you’re not willing to put the time and effort into using a flea collar correctly, it’s probably not the right choice for you.

So, do flea collars work on cats? The answer is yes, but they might not be the best option for everyone. Consider your situation before making a decision.

Why Does My Cat Still Have Fleas with a Flea Collar?

You’ve tried flea collars, but your cat still has fleas. What gives? The truth is that there’s no way to stop fleas completely. Flea collars can help to reduce the number of fleas on your cat, but they’re not 100% effective. There are a few things you can do to help reduce the number of fleas on your cat:

  • Speak to your vet about your cat’s specific needs. They can prescribe medication that will help to kill fleas and prevent them from coming back.
  • Vacuum your house regularly. This will help to remove any fleas and larvae that are living in your carpet.
  • Treat your house. Use a special flea home flea spray that stops the development of flea eggs and larvae and kills adult fleas in those areas that are especially hard to reach. Read the instructions carefully and keep your cat and family away while it works.
  • Wash your cat’s bedding in hot water. This will kill any fleas that are living in their bed.
  • Treat all the pets in the household. Otherwise, you won’t keep parasites under control.

If you’re still having trouble with fleas, talk to your vet. They can prescribe medication that will help to kill fleas and prevent them from coming back.

How Do I Know if My Cat’s Fleas Are Gone?

Okay, you’ve tried the flea collar, but you want to make sure those fleas are gone for good. Here are a few things you can do to check:

  • Check your cat’s fur and skin for any signs of fleas or other parasites. If you see any, remove them with a fine-toothed comb, check if they are dead or alive, and dispose of them. If they are dead, your flea product is working. If the fleas are still alive, you should speak to your vet and change your strategy. 
  • Inspect your cat’s coat, bedding, and sleeping areas for any flea dirt. If you find any, wash the bedding in hot water and vacuum the sleeping areas thoroughly. You should stop seeing flea dirt as the fleas die off.
  • Watch your cat’s grooming habits. If your cat is still itching and overgrooming, chances are they are still suffering from an infestation.

If you follow these steps and fleas are still bothering your cat, it’s possible that the flea collar is not working. You may need to try a different method of flea control, such as oral medication or spot-on treatment. Talk to your vet about which option is best for your cat.
