Fleas are found in every state across the U.S., making flea control a widespread necessity.
Fleas are tiny pests that survive by feeding on the blood of their hosts. They often infest animals, causing irritation through frequent biting. Pets can easily pick up fleas from outdoor environments or other animals, bringing them into your home.
If you suspect your pet may have fleas, focus your inspection on three key areas: your pet, your home, and your property. Understanding where fleas thrive and identifying infestation hotspots will help you target your treatments effectively.

How to Remove Fleas from Your Pet, Home, and Yard
Successfully eradicating a flea infestation requires treating all areas where fleas may be present, including your pet, your home, and your yard. If any of these areas are overlooked, the infestation will likely persist.
For the best results, begin by treating your pets, then move on to your home and yard. Ensure that all treatments are carried out around the same time to achieve maximum effectiveness.
Flea Treatment for Pets
Flea control often begins with treating the pets living in your home or on your property. When starting flea treatment, it’s essential to consider your pet's species, age, and health. Always read the product label to ensure the treatment is safe for your specific pet. There are three primary treatment options for pets:
The best flea treatment for your dog or cat will typically involve using at least one of these methods.
1. Flea Bath
Flea Baths for Dogs, Cats, & Other Pets
A flea bath is one of the fastest and most effective ways to treat pets for fleas. Using a medicated shampoo provides an immediate solution, killing biting fleas on contact, and is the recommended first step for pets with heavy infestations.
Important Tips for Flea Baths:
Challenges with Flea Baths:
2. Flea Drops
Spot-On Flea Treatments for Dogs, Cats, & Other Pets
Spot-on treatments, commonly referred to as flea drops, are a convenient and effective method of flea control. These treatments are designed to be low-stress for pets and provide lasting protection against fleas. Most products are species-specific and should not be used on animals under 12 weeks old.
How to Apply Flea Drops:
What to Expect:
Maintenance:
Reapply flea drops every 4–6 weeks as directed to maintain protection.
3. Pet Flea Spray
Flea Sprays for Dogs, Cats, & Other Pets
Flea sprays are another effective option for eliminating fleas on pets. These sprays kill adult fleas quickly and offer short-term protection against reinfestation.
What to Know About Flea Sprays:
Choose the treatment option that best suits your pet's needs and follow the product instructions carefully to ensure effective flea control.
teps for Treating Fleas in Your Home
Getting rid of fleas inside your home is a crucial part of an effective flea control program, especially if your pets have been infested. To succeed, it’s essential to treat all areas where your pets have rested, played, or groomed. Indoor flea elimination may take anywhere from 2–8 weeks, depending on the severity of the infestation. This process involves a combination of insecticides and mechanical control methods.
1. Natural Flea Control Options
Non-Chemical Treatment Methods
Vacuuming Tips:
Vacuuming is a critical step in a flea control program. Thoroughly vacuum the entire home before applying insecticides, then continue vacuuming every other day for at least 14 days. Vacuuming brings fleas and their eggs to the surface, stimulates immature fleas (pupae) to emerge from their cocoons, and exposes them to applied insecticides.
Recommended Product:
2. Use a Concentrated Flea Spray
Applying Flea Spray Indoors
There are several types of flea sprays available, including liquid insecticides, aerosol sprays, and flea powders. To control fleas effectively, we recommend using at least two products:
Many aerosol flea sprays combine these two products for convenience. Adding a dust to your treatment plan can further speed up elimination and prevent reinfestation. To simplify product selection, consider using an Indoor-Only Flea Kit or an Indoor/Outdoor Flea Kit available from DoMyOwn.com.
Steps for Treating Fleas in Carpets and Rugs:
Pro Tip
It’s natural to avoid infested areas, but doing so will only prolong the infestation. Flea larvae and pupae need stimulation from activities like vacuuming, walking, and body heat to become active and expose themselves to the applied products.
Avoid Using Foggers or Bombs:
Flea foggers are only effective in empty areas without furniture, boxes, or other obstacles. These obstacles prevent the fog from reaching many areas, leaving parts of the infestation untreated.
Steps for Outdoor Flea Control
A comprehensive outdoor flea treatment involves targeting areas where fleas may be present, including places your pets frequent and locations where stray or wild animals may roam.
To achieve the best results, it is highly recommended to use a combination of two products:
To simplify the process, consider using an Outdoor Flea Kit containing the necessary products.
1. Clear Yard Debris
Prepare the Area Before Treatment
There’s little need to spray open, sunny areas, dry or dusty locations, or hard surfaces like patios or driveways since fleas cannot develop in those environments.
Application Steps:
Pro Tip:
2. Repeat Treatment Every 14 Days
Ensure Long-Term Control
Flea infestations take time to eliminate. You should start noticing a reduction in the flea population within a few weeks, but follow-up treatments are essential.
Mow Your Lawn: Mow 24 hours after applying the insecticide to encourage immature fleas to become active, exposing them to the applied products.
Control Moisture: Avoid overwatering your lawn, keep grass short, and trim trees and shrubs to allow more sunlight to reach the ground. Excessive moisture can accelerate flea population growth.
How to Prevent Future Flea Infestations
After successfully eliminating fleas from your pet, home, and yard, it’s important to take preventive measures to avoid another infestation. Follow these steps to ensure your environment remains flea-free.
Keep Your Dogs, Cats, and Other Pets Protected
Protect your pets from flea infestations by ensuring they are on a regular flea treatment schedule, such as using flea drops or sprays. With a variety of flea control products available, it’s important to read the product label carefully, as some sprays may only provide short-term protection. Additionally, use a flea comb to check your pet’s fur weekly for live fleas or flea dirt.
Pro Tip
If you take your dog to a park or wooded area, give them a quick combing with a flea comb afterward to ensure they don’t bring fleas home. You can also apply a repellent spray to their fur before heading out to help keep fleas at bay.
Prevent indoor flea infestations by regularly vacuuming carpets, rugs, and furniture your pets have access to at least once a week. This helps eliminate flea eggs and flea feces that may have been brought into your home by pets or even on your shoes. Additionally, wash your pet’s bedding frequently to remove any flea eggs that may have been left behind.
Preventing fleas in your yard can be challenging, as wildlife like rabbits, raccoons, and stray cats may visit your property and leave flea eggs behind. However, maintaining your yard regularly can discourage these animals and make the environment less appealing to fleas.
If your yard tends to become infested each year, consider applying a preventive treatment to flea-prone areas in the spring. Continue treating every 30–60 days through the fall to keep infestations under control.
