Wondering whether you have a flea outbreak in your home? Learning the warning signs of fleas is key to spotting an outbreak early and nipping it in the bud before it spreads.

Signs of Fleas

Fleas are tiny, bloodsucking insects that can be a real nuisance to both pets and humans. If you suspect that you have a flea infestation, it’s likely time to call a flea exterminator to eliminate the problem before it gets any worse. Here are the key warning signs of fleas to be aware of: 

1. Itchy Pets

If you notice that your dog or cat is scratching more than usual, it could be a major indicator of fleas. Take the time to closely inspect your pet’s fur for signs of fleas, including tiny black specks (known as flea dirt) or red skin irritation.

2. Flea Bites 

Small red bumps or pimples may appear on your pet's belly, under their legs, at the base of their tail, or on their behind or groin area. This is a clear sign of a flea infestation, and you should hire a local flea removal professional immediately. While uncommon, humans may find small, itchy bumps surrounded by a circular ring of discoloration.

3. Flea Dirt

You may find a substance resembling black pepper on your pet’s skin on their favorite places to sleep. These tiny black specks look very similar to dirt, so you’ll need to test it to ensure it’s residue from pesky fleas. Place some of the suspected flea dirt on a moist white tissue or paper towel and if it stains red, it’s the result of fleas.

4. Skin or Hair Issues

In some severe cases, you may notice hair loss, dry skin, lesions, or infections. Consult a doctor to determine the root cause of new skin or hair problems and whether it’s the result of a flea infestation.

5. Anemia

Blood loss from fleas may trigger anemia, which causes pale gums and is most commonly found in puppies and kittens. Consult your pet’s veterinarian if you notice signs of anemia in them.

6. Visible Fleas

In severe infestations, you may be able to see the fleas themselves jumping on your pet or around your home. If that’s the case, don’t hesitate to call a flea control professional to start the flea removal process as quickly as possible.

7. Eggs

You might find tiny, white ovular eggs around places where your pet sleeps. Inspect your pet’s bedding or favorite cozy spot for flea eggs, and if present, hire a flea control immediately.

How to Know If You Need to Hire a Pro for Fleas

If you suspect fleas on your pet, take them to the vet as soon as possible to get treatment. Your vet will be able to recommend the best course of treatment for them, as well as the best preventative treatments to keep the fleas from coming back.

For the fleas around your home, you should hire a pest control pro as soon as you spot the warning signs of fleas. These pests can spread quickly, and due to their tiny size, may go undetected for longer than you’d like. If you’re unable to tackle the problem on your own, or if you just want the fleas gone ASAP, a professional flea exterminator is the right person to call to get rid of fleas fast.

While you wait for flea control to arrive, wash your and your pet’s bedding, curtains, and any other linens that may have come into contact with fleas in hot water. Dry them on high heat to kill any remaining fleas and eggs. Vacuum your carpets, furniture, and floors frequently to remove fleas and their eggs. Be sure to discard the vacuum bag or empty and sanitize the canister after each use.

Can I DIY Flea Removal?

There are a few effective DIY methods for getting rid of fleas. Firstly, giving your pet a bath with flea shampoo can help get rid of the tiny buggers and their eggs on contact. Apply dish soap around your pet’s neck to deter fleas from crawling up their face to escape. You can also purchase flea collars and topical treatments to kill fleas and prevent future infestations.

As for getting rid of fleas around your home, there are a few different methods to consider. Chemical traps, flea powders, and spray insecticides are all good options, but they can be hazardous around humans and pets, so it’s best to hire a local flea exterminator to ensure they’re used safely. 

If you found flea bites on yourself, know that fleas won’t infest humans. The best course of action is to find and treat the source of the fleas, which is most often your pets. You can treat your flea bites with antihistamines, hydrocortisone cream, and an ice pack to reduce pain and swelling.

How to Prevent Fleas

Preventing fleas is much easier than waiting until they become a serious problem. Here are the best ways to prevent flea infestations in your home and pets:

  • Regularly treat your pets with flea prevention products, such as flea collars, topical treatments, or oral medications.

  • Keep a close eye on your pet after they've been targeted as the host and speak with your vet about the best way to follow up with flea care, especially in theweeks after the first treatment.

  • Vacuum your carpets and furniture regularly, wash your pet's bedding often, and keep clutter to a minimum.

  • Steam clean your furniture and rugs on a regular schedule after an infestation.

  • Keep your yard well-maintained and free of things that attract fleas, such as weeds, tall grasses, wood, and leaf piles.

  • Maintain a regular house cleaning checklist to keep your home and belongings clean and flea-free.

  • If you do not have pets at home, spray a potent flea deterrent such as heavily diluted lemon, eucalyptus, or rosemary essential oils in flea-prone areas.

  • If you have pets, look for pet-safe sprays with similar scents at your pet store made from ingredients that will not affect your furry family members.

  • Seal up cracks in your home, including in screens and around doors.

  • Regularly check for signs of fleas and address potential infestations the moment you find a bite on yourself or your pet.

Frequently Asked Questions

A flea can live as long as 100 days when it has a live host to feed on. They tend to live a much shorter life when they’re on a short-haired dog or cat versus a pet with longer hair. Without a host, fleas will typically only survive for about one to two weeks.

There is often confusion between fleas versus ticks, bedbugs, carpet beetles, lice, fungus gnats, and flea beetles. Learning how to identify and differentiate between these insects is key for effective treatment. If you are unsure, it's always best to consult with a pest control professional who can properly identify the pest and provide the best treatment options.

While taking a shower can help wash away fleas and their dirt from your body, it may not completely get rid of all of them. However, if you wash your clothes and bedding in hot water and dry them on the highest heat recommended for the fabric, it can further reduce the possibility of an infestation. However, even if just a few are left, they can reproduce and take over again, so it’s best to take additional measures and call a flea exterminator to ensure they’re gone for good.

According to the Centers for Disease Control and Prevention (CDC), fleas can carry human disease-causing pathogens for Plague, Flea-borne typhus, and Cat scratch disease. These diseases are caused by fleas such as Oropsylla montana, Xenopsylla cheopis, and Ctenocephalides felis, and are commonly found in rural areas of the western United States, California, Texas, and Hawaii. Fleaborne parasites like tapeworms can also be spread to people and animals if they accidentally swallow an infected flea, and small children are at a higher risk. Symptoms may not be present in most infected people.
