Riding your yard of fleas can be a daunting task, especially if you're not sure where to start. Learn where fleas can be found in your yard and how to get rid of them for good!

Youโ€™ve taken the steps to de-flea your house, but the battle might not be over yet. Fleas are pests that can endure and breed in the outdoors until they find a new furry home. It is reasons like this that make monthly flea preventatives like Comfortis or Revolution for dogs so crucial.

If your pets spend a lot of time in your yard, it might be necessary to treat everything from the lawn to your lawn furniture for these parasites. Learn where fleas can be found in your yard, how to eradicate them, and how to prevent future invasions of fleas on dogs.

How to Check Your Yard for Flea Infestation

Itโ€™s important to make sure the yard is not the source of your flea infestation. Walk around your yard wearing white socks pulled up to your calves, and linger in the areas your pet hangs out most. Youโ€™ll easily spot fleas against the white cotton of your socks if they are present.

Fleas prefer cool, shady, moist places. They especially like shrubs, leaves, and trees, and donโ€™t fare well in sunny areas or in open grass.

The first place to look for fleas is the spots your pets frequent most. Anywhere your pet likes to sleep, rest, dig, or run is where fleas will likely be. Poke around the doghouse, kennel, outdoor furniture, and shady trees or gardens. Also check out the patio, underneath the porch, along fences, and around your houseโ€™s perimeter.

Preparing Your Yard for Flea Treatment

After you treat your pets with something like Advantage for cats and declare them flea-free, begin treating the yard. It's best to keep pets out of the area until you eradicate the pests completely. If a few lingering parasites jump on your dog or cat, the whole process could have to start over again.

Begin by thoroughly cleaning your yard. Itโ€™s probably on your to-do list anyway! Mow the grass and pick any weeds you see. Remove debris from the garden as well as your lawn. Stacked wood, piles of leaves, and mounds of rocks are the ideal breeding ground for fleas. The more clutter, the more places fleas can take refuge. You should also keep the yard free of pet and child toys during this process.

Treating Your Yard for Fleas

Once you choose your method of flea removal, be it insecticides or a more natural solution (see below), focus on the places your pet frequents first. If you have a giant yard, you may not need to treat the entire area. If your pet doesnโ€™t frequent the front yard or is fenced off from certain areas, it wonโ€™t be necessary to treat those places. Doghouses and kennels should be sprayed with the same non-toxic product you use to treat your pet.

Using Insecticides to Treat Your Yard

If you choose to use a pesticide to eliminate outdoor fleas, follow the directions on the product label, and make sure to abide by all safety warnings. Most flea pesticides come in the form of hose sprayers or tank pumps. You can hire a professional to administer the treatments, but if you prefer to do it yourself, make sure to cover up. Wear a dust mask, protective clothing, and gloves.

Make sure you remove toys from the yard before spraying and keep children and pets off the treated areas until those areas are dry, or until the product instructions indicate it is safe. Most applications of insecticide will need to be repeated in two to three weeks after your first round.

Flood Your Yard to Remove Flea Eggs

Once youโ€™ve eradicated fleas from your yard, you still have to contend with their offspring. Fleas breed in those moist, shady areas we discussed earlier. Hose down garden beds, around trees, rock mounds, and anywhere else you suspect fleas are hanging out. Next, water your grass until it slightly floods. Eggs and larvae will not survive when flooded with water.

Diatomaceous Earth for Fleas

Diatomaceous earth or DE provides a natural way of dealing with fleas dwelling in your yard. Free from harmful toxins, diatomaceous earth is a fine dust that's made from fossilized remains of a type of algae called diatoms. This natural pesticide kills fleas while being completely safe for mammals. You can spread DE using a garden dust-spreading tool on areas that are heavily infested. These areas are usually near the doghouse or any places where your pets spend the most time. However, DE only works when itโ€™s in dust form. Therefore, you should avoid using it during the wet months.

Beneficial Nematodes and Flea Removal

Nematodes are a natural, non-toxic defense against fleas. These microscopic worms are harmless to humans and pets, and will not cause damage to trees, grass, bushes, or plants. They feed on flea larvae and attack other pests in your yard as well, like termites. Nematodes typically come in spray form and should be applied to the shady areas that fleas frequent, as they cannot tolerate the hot sun either.

Cedar Wood Chips and Fleas

Cedar chips are another natural way to keep fleas at bay. These parasites are repulsed by the scent of cedar chips and do their best to avoid them. Sprinkle the chips in those shady areas that fleas frequent in your yard, as well as under the porch, dog bedding, and outdoor furniture. You can mow right over cedar chips, turning them into a finer powder that will still repel the fleas. Sprinkle them along your fence to keep fleas from neighboring yards out.

Prevent Future Flea Infestations in Your Yard

If your pet is prone to fleas, take these measures to make your yard less flea-friendly.

  • Keep Your Lawn Dry: Fleas thrive in moist places, so do not over-water your lawn. Youโ€™ll create a flea-friendly breeding ground for these parasites.

  • Use Cedar Chips Decoratively: Given fleasโ€™ aversion to their smell, try incorporating cedar chips decoratively so they have a permanent place in your yard.

  • Consider Planting Pennyroyal: Pennyroyal, also known as fleabane, naturally repels fleas once itโ€™s fully established in your yard. This plant is a member of the mint family, and fleas do not like its scent. Use pennyroyal with caution, as it is toxic to cats if ingested, and is not recommended around pregnant animals.

  • Prune, Trim, and Mow: A sunny yard is not an ideal habitat for fleas as they cannot tolerate hot sun for long periods. Frequently mowing your lawn exposes the soil to sunshine, keeping it dry and flea-free. You can also prune bushes and trim trees to increase the sunniness of your yard, and keep fleas out.

How to Kill Fleas in the Yard

The impressive jumping abilities of fleas allow them easy entry into your home, hitching a ride on your pants leg or on your petโ€™s fur. Once inside your home, fleas will torment your cat or dog, and multiply at a swift and overwhelming rate. Ticks, which can be more frightening from a disease perspective, hide in grass and can also easily attach to you or your pet. Prevent your backyard from becoming a comfortable breeding ground for these harmful parasites, and find out how to eliminate these pests if theyโ€™re already cozily in place.

Preventing Fleas & Ticks From Inhabiting Your Yard

Your lawn can be tempting for fleas and ticks, particularly if it is somewhat overgrown. Try following these easy tips to ensure that your backyard stays free of pests:

  • Keep grass well-trimmed: While fleas and ticks like to lurk within the grass, direct sunlight will make the soil and grass too hot for them to survive. Mow the lawn frequently to maximize sun exposure.

  • Water Abundantly: Flooding areas with a flea population can be another strategy since it drowns and destroys flea larvae.

  • Be Deer-Free: Deer are prime tick-carriers, so prevent deer from coming on your land with fences. Avoid planting fruits and vegetables that are particularly appealing to deer, such as tulips and lettuce.

  • Organic Matter: Compost, piles of leaves, and other organic matter are a  prime breeding ground and home for fleas and ticks. Avoid having organic matter where your family or pets walk and play, not that we'd want to deter you from composting altogether!

  • Separate play areas: Your deck, playground equipment like slides, and the grassy areas you and your pets walk on, should be kept separate from complete nature with a barrier of wood chips or gravel. The CDC recommends keeping this barrier 3-feet wide.

Eliminate Fleas in Your Yard

But what if itโ€™s too late to prevent fleas, or if you live in a warm climate, where fleas and ticks are nearly unavoidable? Try one of these solutions:

  • Chemical Remedies: To remove fleas and ticks from the yard, you can spray an Insect Growth Regulator (IGR). These treatments are generally safe for people and pets and will inhibit the fleaโ€™s life cycle and prevent further offspring. Be cautious about applying these near a water source, and note that IGRs are harmful to fish. Acaricides, or a tick pesticide, can be applied on a yearly basis to ward off and destroy ticks in your backyard.
  • Diatomaceous Earth: While hazardous to ingest or breath in, this natural product can be used as an insecticide without harm to humans or pets. Apply food-grade Diatomaceous Earth on dry days to areas of the garden where you have spotted fleas and ticks. Wear gloves while sprinkling it around to avoid irritating your skin. When fleas, ticks, or insects encounter or ingest Diatomaceous Earth, it dehydrates and shreds their bodies, eventually destroying them completely.
