You may connect this spray to your garden hose and use it to spray your lawn. It’s a touch more expensive than some of the other options, but it gets rave reviews.

You might be asking why it’s so low on the list with a 4.5-star average review, but the spray is only legal in Connecticut, Maryland, Vermont, and a few New York counties. It’s unclear why they’re ineligible in all of these states.

Connecticut requires all pesticide products to be registered with the state, which could explain the difference, but Vermont and Maryland do not have such rules. They do, however, have certain regulations on pesticide use.

Overall, the product looks to be safe based on the positive evaluations, but the limits on use in some jurisdictions may deter potential buyers.

Choosing the Best Flea Killers for Your Yards: A Buyer's Guide

While it comes to flea killers, there are numerous aspects to consider when deciding on the best treatment for your yard.

The most important considerations are flea killer kind, chemicals, coverage area, and application method.

Pet owners might also consider utilizing an Insect Growth Regulator (IGR) treatment, which will eliminate not just adult fleas but also flea larvae and hatching flea eggs.

IGR treatments can help in the fight against an infestation by killing fleas as they develop.


One of the most important considerations for pet parents is whether to use an all-natural spray or a synthetic chemical spray.

However, it’s vital to realize that the term “chemical” has a poor connotation among the general public.

Chemicals are used in the manufacture of everything. Water is a chemical, and we wouldn’t hesitate to give it to our pets!

To protect your and your dogs’ safety, whether you use a natural or synthetic flea killer, it’s critical to follow the instructions to the letter.

Avoid over-treating your lawn, and keep your dogs inside until the spray has completely dried. Only you can determine whether you’re comfortable using synthetic chemicals near your pets.

Furthermore, many pet parents are wary of employing sprays containing pyrethrins or pyrethroids.

While these substances are harmless for humans and pets, the EPA warns that they can be lethal to beneficial insects such as bees. As a result, we’ve excluded any pyrethrin sprays from our list.

Area of Coverage

If you have a large yard, you may require more than one treatment container to cover the entire area.

A smaller, less expensive container may be appealing, but if you undertreat your yard, you will not eliminate the fleas.

When choosing a flea killer, consider the size of your yard. If required, measure your yard to ensure that the flea killer you’re purchasing can treat your entire property.

Type of Application

Most flea remedies for the yard connect to your garden hose. You treat your yard by spraying it with your hose through the applicator.

Some treatments are available as granules or through specialised spray systems. Pet owners should think about how the treatment will be applied.

People with mobility or lifting issues should avoid granule treatments and dedicated spray systems in favor of hose applicators.

Insect Growth Control

In your yard, particularly stubborn infestations may necessitate the use of an IGR treatment to inhibit the growth and hatching of young fleas after the contact has killed the adults.


Flea treatments are crucial for many pet owners, whether they are attempting to prevent a flea infestation or are already dealing with one.

Choosing the correct treatment for your yard is a responsibility that owners take seriously because the health of their family members is at stake.

Vet’s Best Flea and Tick Yard and Kennel Spray is our favorite overall product, and if you’re looking for a solid value at a decent price, Ortho BugClear provides enough of flea management bang for your buck.

BestForPets (bestforpets.org) hopes this best flea killers for your yard list was able to help you narrow down your options or locate the best flea treatment for your needs.
