Future Flea Prevention

So now you’ve got rid of the fleas, it’s time to make sure they don’t come back. Remember, animals can catch fleas from lots of places, and being indoors-only or not having contact with other pets is no guarantee of avoiding fleas.

Let’s look at some ways we can prevent flea infestations from recurring.

Regular flea medication

The simplest way to prevent a future flea infestation is to make sure all animals are covered by flea treatments reapplied according to the packet guidelines. Any of the flea treatments discussed in the medication sections for cats and dogs can be used for this purpose.

This can be expensive, but in most cases regular preventative treatment is cheaper and less stressful than reactive treatments every time an infestation happens.

However, there is also an argument that regular flea treatments are bad for the environment, and aren’t always necessary.

Flea prevention without flea medication

If you think that year-round prevention isn’t possible or necessary for your pet, you could try applying flea products in the summer only, and depend on household management and repellents to protect in the winter. Here’s a prevention plan that may help protect your pets if they’re at low risk of catching fleas:

  • Make sure that new animals entering the house are treated to ensure they’re flea-free.
  • Weekly grooming will ensure you spot a breakthrough flea problem quickly, so you can act fast.
  • Repellents should be considered whenever your pet is leaving the house. However, not all repellents on the market are effective, and some are unsafe. Choose products with clinical trials and evidence of safety where you can.
  • Apply medication if pets get fleas or are at high risk of catching fleas – for instance, if going into kennels or daycare.


Once you’ve got rid of your flea infestation, it’s time to prevent it from coming back. Some people have high-risk pets or lifestyles, and decide to use flea treatment year-round. In this situation, try to choose products that suit your pet’s lifestyle to minimise environmental contamination. Others use combinations of grooming and repellents for some portion of the year, reserving flea medications for when there’s a problem or when the risk is higher, like in the summer.

Key Takeaway

The only way to be sure of preventing a future infestation is by using flea products year-round. However, some pets may get away with using products for only part of the year, depending on their lifestyle.
