Fleas and pets at home

Your pet is like family, and just having a pet in your life can have health benefits, like boosting your mood. However, if you have a dog or cat, fleas—even just the fear of them—are likely the bane of your existence, especially during the warm, humid summer months. You likely start to panic every time Fido or Fluffy scratches, and with good reason.

“If your dog or cat has fleas and you don’t treat it with something strong right away, 30 fleas will breed to a quarter of a million fleas within a month,” says John Howe, president of the American Veterinary Medical Association and manager of North Country Veterinary Clinic in Grand Rapids, Minnesota. This means eliminating fleas and immature forms of fleas from your pet and your indoor and outdoor environment. (Here’s how to reduce indoor air pollution.)

Understanding the flea’s life cycle

Fleas are tiny, wingless insects that feed on the blood of animals and people. Their life cycle comprises of four phases. The adult fleas lay eggs, the eggs hatch into larvae or tiny worms, the larvae turn into pupae, and the pupae spin a silk-like cocoon and eventually turn into adults. An adult flea must attach to a dog or other mammal to complete its lifecycle, but will also jump onto a human for a snack while waiting for its mate. “Fleas will usually pick one person in a family and attack them viciously with bites up and down their legs, so it’s important to use really good flea products in the home too,” says Howe.

Without a host, adult fleas live for up to two weeks. They live an average of eight days on short-haired cats and dogs and longer on long-haired animals. The female flea begins laying eggs within two days of her first meal, and these eggs can spread in your home and yard every time your dog or cat scratches, shakes, or lies down.

How do I prevent fleas in my home?

Preventing fleas starts with making sure your pet is on a fitting flea prevention regimen all year round. “Brush your pet often, shampoo your pet regularly, use preventative insecticidal pills (or treats) or spot-ons [medicinal liquids],” says Coby Schal, PhD, Blanton J. Whitmire distinguished professor, entomology & plant pathology, North Carolina State University, Raleigh. (Here’s how to tell the difference between a bed bug and a fleabite.)

Whether you want to prevent or get rid of fleas, our flea experts explain what to look in a product when trying to protect your pet and home from a flea infestation. Here’s a roundup of our expert-recommended flea products for pets and for humans to protect the home.

Combing through Fido or Fluffy’s coat after a bath is a good way to find any stowaway fleas, flea eggs, or flea dirt, says Carol Osborne, a holistic veterinarian based in Chagrin Falls, Ohio.  However, you don’t necessarily need a specialized flea comb to do this, she adds.

That said, the Flea Comb for Cats Dogs Fine Tooth Comb Pet Comb Grooming Set offers multiple options depending on your pet’s hair length, and is an Amazon’s Choice product. Its round teeth can break up any mats in your pet’s hair and there’s an added bonus: It includes a tick removal tool too.

Vacuuming can remove up to 30 percent of the larvae and up to 60 percent of flea eggs from a carpet along with the larvae’s food supply, according to Osborne. The Shark Navigator Lift-Away Professional includes a high efficiency particulate air (HEPA) filter, which is a mechanical filter that can trap dust, indoor allergens, like cockroaches, pet dander, without trapping gases. This is important since fleas could potentially get in and out of the vacuum canister or bag.

Don’t miss any spots especially below your drapes, underneath your furniture, and anywhere your pet sleeps. If you opt to use another vacuum cleaner, Osborne suggests to “throw out the vacuum bag if your vacuum requires one.” “If your vacuum uses a cylinder, thoroughly clean it with bleach when you are done or the eggs will hatch in there,” she adds.

Osborne recommends NexGard for flea prevention in dogs. “It’s given monthly as a chewable, and the active ingredient is afoxolaner, which targets and kills adult fleas before they can lay eggs,” she says, noting that different flea treatments target different parts of the flea life cycle. NexGard is only available with a prescription from your veterinarian.

Other oral prescription flea prevention products for dogs include sarolaner (Simparica), fluralaner (Bravecto), and lotilaner (Credelio), adds PetSmart’s resident veterinarian Jennifer Freeman, who also owns Higley Groves Animal Hospital in Mesa, Arizona. Bravecto lasts up to 12 weeks and comes in a chew as well as a topical solution. Credelio tablets are for dogs and cats, she says.

All of these medications are in the isoxazoline class, and the U.S. Food and Drug Administration recently warned that dogs and cats who are treated for fleas with medication in this class are at risk for seizures, tremors, and other neurological side effects.

“When it comes to oral preventatives, I always recommend pet parents consult their veterinarian to decide what the best preventative is for their pet. Your pet’s age, pre-existing health conditions, and dosing interval preference (i.e. monthly doses versus doses every three months) play a role when deciding what product to move forward with,” Freeman says. (Got allergies? Pet dander can actually be a trigger.)

Fleabusters Rx for Fleas Plus is an Amazon top seller. This contains boric acid which can be effective at killing flea larvae, says Merchant. “Boron salts are stomach poisons for insects, so they have to be ingested to work,” Merchant explains. Since adult fleas are blood feeders only, these salts are ineffective on the adult stage. That said, the pre-adult stage is susceptible. “When flea larvae are foraging in carpeting or pet bedding, they ingest the salts along with their normal food of adult flea poop. This lethal combination can help break the flea life cycle. Make sure to vacuum all carpets and floors and throw away the vacuum bag, he says. “You usually need a follow-up treatment within 7-10 days or sooner with shorter-acting insecticides,” Merchant adds. (Beware of these germy everyday items.)
