Do Flea Collars Really Work?

Flea collars are designed to kill fleas on dogs. Some types are effective in keeping fleas off pets for three to eight months. The long-lasting versions are especially useful for busy households or pets that spend time outdoors. However, there are some important things to consider before deciding on a particular collar.

Flea collars are easy to apply and release a chemical that kills fleas. They are not as messy as topical spot-on treatments, and they are usually less expensive per month. It is important to note that even the cheapest collars do not guarantee successful flea control.

Flea collars work differently for every type of dog. Some will start working within 24 hours, while others may take up to two weeks before their full effect becomes apparent. While most collars are safe for dogs, some can cause negative reactions. For example, some ingredients can irritate a dog’s skin, so it’s important to read the labels of any collars you purchase.

While many flea collars contain chemicals, some are made of natural ingredients, and these are generally more effective. Some of these products contain essential oils such as lavender or citronella, which swats off tiny nasties.
