Searching for the best flea killer for your yard is something that most pet owners do at some point in their lives. Flea and ticks are both pesky parasites that plague our dogs the moment they step outside. If you don’t deal with a flea infestation, it is going to be an unpleasant time for your pup and other animals in the house. On top of reading through these reviews, you might also want to schedule a trip to your local vet and get them prescribed some flea and tick medication as soon as possible.

    Form: Granules

    Ortho Home Defense Insect Killer for Lawns comes in many different container sizes that keep you stocked for the entire year.

    Wondercide Ready to Use Flea & Tick Yard Spray

    While the packaging looks like other chemical yard sprays, the Wonderside Ready to Use Flea & Tick Yard Spray is a 100% natural solution with organic ingredients like cedarwood oil that deters pests. Because there are no chemicals, this product isn’t going to work as quickly or be as effective as other formulas. However, the ingredients kill bugs going through each stage of the life cycle and not just adults. This spray covers 5,000 square feet and is suitable for small or medium-sized yards.

    Pros
    • 100% natural ingredients
    • Kills bugs in all life stages
    • 5,000 sq. ft. coverage

This yard and kennel spray contains cinnamon oil that is surprisingly effective at deterring bugs but not so much killing them. It is listed as a reasonable price, yet it is probably better to use it inside the house to repel pests rather than kill them outdoors.

    Pros
    • Affordable
    • Clean formula
    Cons
    • Only covers 4,500 sq. ft.
    • Repels bugs instead of killing them

    • Highly effective
    • 13,000 sq. ft. coverage

    Buyer’s Guide: Choosing the Best Flea Killer for Your Yard

    Purchasing such harmful chemicals to use around your pet is a daunting task. On one hand, you want to kill all the nasty pests outside, but on the other, you don’t want to cause any harm to your pets. Always follow the instructions exactly as they are printed on the container’s packaging. These guidelines are put into place so that you don’t cause any harm to your, your family, or your pets upon application.

    Listed below are several different factors for you to consider before purchasing the best flea killer for your yard. Pay attention to each one and think about how they are going to work around your property.

    Ingredients

    Ingredients are the most vital part of the buying process. Without the right ingredients, the fleas won’t go away. You also don’t want them to be so powerful that they make you or your pet sick. Flea treatments come in either chemical or organic options. As you probably guessed, the chemical treatment is often more effective. Still, such strong products aren’t always necessary, and you could easily amend them with more natural solutions.

    Coverage

    All the various flea killer formulas are complex and will work differently depending on the coverage area. Make sure to only use brands that are suitable for the area you’re working on and have enough product to be effective.

    Application

    Flea treatments usually come in the form of a spray. You might have to supply your own garden sprayer or spray bottle so that you can mix the solution.

    How Long Does Flea Spray Take to Work on Your Yard?

    High-quality flea killers should kill most adult bugs within one to three days. Products with all-natural ingredients could take up to two weeks and multiple applications to be effective. Remember to always check the instructions to determine how much and how often you should be spraying.

    What if it Rains After I Spray My Yard for Fleas?

    It’s possible that you go out and spray your entire yard only for the rain to come and wash it away. Light rain isn’t likely to wash away the flea killer. However, heavy downpours can significantly reduce its effectiveness. You may have to apply to solution again, so check the weather each time before heading outside.

    If you happen to apply the treatment about a day before the rain comes, it will most likely still be effective. When in doubt, there are some more weather-proof solutions on the market that aren’t easily affected by rain and sunlight.
