Yes, a flea collar can still be effective if it gets wet. The waterproof layer in the material of modern flea collars protects the active ingredients from being washed away. However, some older or cheap flea collars may not be as effective if they get wet as the active ingredients will become much less potent or even ineffective.
In addition to being waterproof, many modern flea collars also provide long-term protection against fleas and ticks for up to 8 months. This is due to the slow-release of the active ingredients that gradually seep out over time and spread over your pet’s fur, providing continuous protection against pests.
To ensure your flea collar continues to work effectively, it’s important to follow the product instructions carefully, particularly when washing/bathing your pet while wearing a flea collar. Usually it’s best to remove the collar and put it in a sealed container until you’re ready to use it again.
Additionally, replace any weak or broken collars immediately as they won’t be able to protect your pet from pests effectively anymore!
To conclude
When used correctly, a flea collar can help protect your pet from fleas and other parasites regardless of whether it gets wet or not. However, take care when using one to ensure its effectiveness and remember to remove it when your pet goes swimming.
