The Best Flea and Tick Killer for Lawns: Is It Safe for Your Family?

Getting rid of a flea and tick problem means more than just buying Fido or Fluffy a collar. If the problem is inside, it could well be outside, too — especially if your pets go in and out. If you have fleas and ticks, you need to treat your house and possibly even your yard. But there are a lot of products on the market. How do you find the best flea and tick killer for lawns?

Fleas and ticks can hide in the tiniest nooks and crannies, so you want a strong spray to get them to matter where they are. However, many sprays on the market right now contain ingredients toxic to pets and humans. What are the chances those same chemicals won’t hurt your lawn, your pets, or other unwitting critters just passing through? Is there a lawn treatment that’s effective, affordable, and relatively safe, as well?

How to Choose the Best Flea and Tick Killer for Lawns

Plenty of products claim to be the best flea and tick killer for lawns. However, you need to consider a few factors before deciding which one is the best for your needs.

Is it user-friendly?

First off, you need to see if the flea and tick killer is easy to handle and use. Is the dispenser easy to use? Do the buttons require extra pressure? Does the handle fit your hand? What about cleanup? Does the spray leave a potentially harmful residue that will leave you with a second messy job to do?

Is it fast?

The best flea and tick killer for lawns will act at once. No one wants to torture animals, and even fleas or ticks are living creatures. An effective product will deal with them swiftly and mercifully.

Does it kill fleas at all stages?

Some products only kill off the adult specimens, leaving the eggs and larvae. The best flea and tick killer for lawns will eliminate each and every trace of those pests, thus ensuring that they’re unlikely to infest your property again.

How long does it last?

The killing impact of the best flea and tick killer for lawns should last for some time. That will prevent any new uninvited pests into your area.

Are there any health risks?

Look at the ingredients of the flea killer to decide whether it’s safe enough to spray in your yard. Since you’re going to apply the product directly on your lawn, it should have a relatively low percentage of active ingredients and insect growth regulators. Organic flea killers are available as safer options, but they might not last too long or be as effective.

How large an area does it cover?

You don’t want to have to re-spray or run to the hardware store for more halfway through the job. The best flea and tick killer should cover a large area.

Safety First!

There are several precautions to take before treating your lawn with insecticide. Even organic pest control can have side effects, so, whatever you buy, know how to handle it safely.

Restricted area

Make sure no children or pets go into the lawn for around 24 to 48 hours after you’ve sprayed it. Even after the smell has faded away, some pets might experience allergies and other negative reactions. Both children and pets also run the risk of putting leaves or grass in their mouth, which may cause them to ingest the spray.

Lawn upkeep

The best way to make sure the spray is effective and your lawn stays pest-free afterward is to keep everything under control. Mowing the grass, trimming the shrubs, and removing anything that could attract stray animals is a wise idea. The latter includes trash, debris, and dead plants. Rodents and strays usually carry fleas and ticks, so they might be the cause of a reinfestation.

Treat everything

When you’re spraying the lawn, make sure to include the dog’s kennel, porch, patio, and any bedding. Make sure you get to every place where pests can hide. You shouldn’t spray the animals themselves, but if you find fleas or ticks on your pet, treat them with the appropriate product. It’s also good to keep the crawl spaces and other damp, hidden areas in mind while spraying the tick killer.

Overall Pricing

The price ranges for the best flea and tick killers vary according to the brand and the ingredients they include. The stronger, more concentrated ones last longer and are generally more expensive. The expected price range for these sprays is between $20 and $110.
