How To Choose The Best Lawn Grub Killer

It can be pretty daunting figuring out which grub killer is the best for your lawn, with plenty of options to pick from it can be a little overwhelming, especially since many people don’t know how to choose the best one.

There’s a few things you’ll want to consider when choosing the best grub killer for your lawn:

Types Of Grub Killers

Grub killers will typically come in two different types, they either come in liquid form or a granule type of form.

Liquid types of grub killer products usually need to be diluted before you’re able to apply it onto your lawn, liquid based concentrated grub killer products can be easy to apply with a sprayer, however they can be hard to evenly spread throughout your yard.

Granular types of grub killers are usually top picks for many homeowners, they’re very common as they can easily be spreaded on your lawn. For granular grub killer products, you’ll want to pick one that doesn’t clump up much, but also isn’t a pure powder. After spreading it across your lawn, you’ll just need to water it and let it dry for it to begin killing grubs.

Grub Killer And Preventer

Grub Killer And Preventer

Many products have split between being a grub killer, that doesn’t last long but does kill grubs and other products are able to prevent grubs from intruding in your yard altogether. However, the best types of grub killer products typically have both of these abilities in one, meaning it will be long lasting and kill effectively.

Chemical Grub Killer vs Organic Grub Killer

There’s plenty of grub killer products that use chemicals to kill insects, many of the best lawn grub killer products will include chemicals in them to effectively kill off grubs that are intruding in your yard, but with chemicals being spreaded in your yard, this does mean that there is some drawbacks to using grub killer products with chemicals in it.

They use chemical insecticides, which can kill off beneficial bugs such as earthworms and bees. The chemicals used are also toxic to other aspects other than just bugs, meaning you’ll want to ensure you don’t use chemical based grub killers around waterways.

When it comes to organic grub killer products, you won’t find many that effectively do the job that grub killers with chemicals can do. However, if you’re having issues with Japanese grub beetles, then it may be worth your while to try an organic milky spore.

When And How You Should Apply

Regardless of what grub killer you decide to get, applying it as quickly as you can when you notice grub worms in your yard will help prevent a lot of damage that could potentially happen by waiting.

Many grub killers will only be affected when grubs are young and feeding. Typically you’ll see this happening in the Summertime. The time frame depends largely on the area you’re located in.

Once grubs begin to grow larger, they can dig deeper into your soil. This usually happens in fall, so it’s best to not apply grub killer in the fall as they won’t be actively feeding so it probably won’t kill them.

If you apply the grub killer too early into the year, it will begin breaking down before any eggs can begin to hatch. Whenever you apply grub killer granules to your lawn or landscaping, you’ll want to ensure you’re watering it enough as failing to do so will result in it not breaking down completely.

Since grub killers have chemicals in them, you’ll want to make sure you don’t allow children or pets to roam on the lawn while it’s wet, wait for it to completely dry before allowing them to play in the yard again.

It’s also not recommended to use liquid based grub killers while it’s windy outside, as this could make it go into areas like waterways and gardens.

Of course there could be other reasonings on why your lawn could be turning brown, but it’s typically from grub worms. If you notice any C shaped type of worms, then your lawn has grub worms in it. However it should be noted that grubs aren’t the only reason why your lawn may be brown and withering, it could also be because of shade. Since shade can prevent grass from having strong roots, this means you will be able to easily pick the grass from your lawn.

  • What To Do After Grub Damage Has Been Done

Whenever grubs intrude on your lawn and begin damaging it, it can certainly be upsetting. When your lawn has become damaged severely, then you’ll have to do some renovation to your lawn. Taking away all of the dead debris will be the start, then water your lawn. Just because the roots of the grass are damaged doesn’t mean they’re completely useless, they can come back and begin getting stronger.

  • How Do I Keep Grubs From Coming Into My Lawn?

How To Tell If You Have Grubs

If you’re suspicious that your lawn may be suffering from grubs, then you want to do an inspection to see if there’s any grubs and how many are in your lawn. An inspection should be done in spring.

If it’s more than 5, you’ll want to monitor your yard for them as they’ll become a major problem to your lawn.
