fast facts


For tick and flea awareness month, has a list of the best-rated flea preventions and remedies on Amazon.

It’s flea and tick awareness month. May’s warmer weather and longer days will tempt pet owners into spending more time outside with their furry friends, but spring weather also marks the start of flea and tick season.

Fleas aren’t just uncomfortable for your pet, they can also carry disease. Your pet can pick up fleas from contact with an infested animal or their environment. Prevention is a good place to start. Keep your yard landscaped so pests have fewer places to hide; and don’t keep pet food outside, which could attract wildlife. Give your pet a quick brush before coming back inside. If your dog or cat has long hair, consider keeping it shaved in the summer so you can spot any problems. Shampoo frequently. Vaccum your home regularly, as well as your car if your pet comes rides with you.

When it comes to treatments, it’s important to learn about the flea’s life cycle as some products will only work on certain stages. Check out the top-rated treatment and prevention products below, selected based on customer reviews.
