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.

Conclusion

After reading our top reviews, this article should have helped guide you in the right direction. There is no shame in wanting to use more potent chemicals to take care of the job the first time as long as you follow safety protocols and ensure that your pets won’t come into contact with them.
