How to Choose The Best Grub Killer For Lawns?

How to Choose A Best Lawn Grub killers?

It’s not easy to dig out the best grub killer for your lawns among all the markets. To make this job really easy I will suggest you follow my 3 simple tips.

I hope by following all of these, you may able to find the perfect grub killer you’re searching for your lawn.

Know Types of Lawns Grub Killers

Before purchasing a grub killer, make sure which type you would love to go for your lawn; you’ll find 2 types of grub killers in the market. These are granular and liquid.

Granules are the most common type and easy to use in the affected area via a spreader.

From my experience, I can say the best lawn grub killers won’t clump together too much nor be too powdery. This characteristic of a good grub killer makes this easy for even distribution.

You just need to water them lightly as they dissolver into the soil where it comes to touch with the cruel grubs.

On the other hand, a liquid grub killer comes as either a concentration that you have to dilute before applying or a ready-to-use grub spray. Like the Bayer Crop Science 700280B listed above, some concentrate bottles come with a special attachment to make it simple for you to attach your hose.

Remember spraying grub worm killer over your grass is really quick and easy to do. But it may result in less precise in getting balanced coverage over all areas, so it’s good to be careful when applying it.

Organic Grub Killer Vs. Chemical Grub Killer

I found multiple best lawn grub killers use chemical pesticides as their primary active elements.

They are much effective in killing all the disturbing grubs and various insects. So they work well to killing many insects if you’re a sufferer of multiple insects as well as grubs.

But wait! I found there are also some disadvantages as well.

First of all, sometimes they may cause to damage the life of some beneficial organisms like wigglers and bees.

And they’re poisonous to more than just insects. So you should be careful applying them beside waterways. And you usually have to remain for the treated area to evaporate before allowing children and pets back onto the lawn.

Unfortunately, there aren’t many effective organic grub control products available in the market. But, if you’re experiencing Japanese beetle grubs, then it’s worth considering Gabriel Organics Milky Spore. This will do the task of defending your lawn without the necessity for insecticides. And organic grub killers work slowly but surely, and their existing capacity is much longer than chemical ones.

Grub Killer or Grub Preventer?

Some pesticides kill all insects they come into touch with after they are applied but only have short-term effects. Simultaneously, other pesticides have a surplus action to protect an area for a more extended period.

The best grub killer for lawns consolidates both capabilities. They are giving you quick results, killing any bug that’s active in your lawn— keeping them off for the rest of the season or more.

When & How To Apply Grub Killer?

When & How To Apply Grub Killer?

No matter which product you choose, it’s essential to implement it immediately once you see grub infestation signs to decrease the destruction they do to your lawn.

I found most of the products work effectively only when the juvenile grubs are actively feeding beside the soil’s surface. It’s a common period between summer, with the first week in August being an expected time to attempt control. But it always varies depending on your region and product.

While the grubs turn mature and warmth start to drop later in late September, they dig deeper into the soil and make them harder to kill.

So applying all the pesticides too early in the year is not a wise step. Because it may cause breaking down all the chemicals before the grub eggs have had an opportunity to hatch.

The next common but most importantly after implementing granules to the soil, just remember to water the field sufficiently to dissolve into the ground perfectly.

If you follow all the instructions written in the product’s manual, then all of these grub killers are not a matter of health concern. But it’s always a great practice to be extra cautious about handling any toxic elements. For your child and pet safety, let your lawn dry before allowing them.

Another great suggestion from my end is that try to avoid using them when windy. Especially with a spray as it will flow all into your fields that you don’t want to deal with.

Checking Procedure For Lawn Grubs

If you presume that you are experiencing the grub problem, it’s best to check during spring as it’ll give you a better sense of their number.

To test the root area properly, cut your lawn grass via shovel or spade and roll back the turf. Now it’s time to count the quantities of the grubs between 1 sq. ft. Continuously do this job until your satisfaction in different areas and take an average note. 

If you find less than 06 grubs per square feet, then my experience says it’s not going to happen a major problem later in summer for your lawn. Otherwise, if the average number is 06 or above, then carefully observe the situation and be ready to fight with all the nasty grubs.

There are also some great tricks to check out your lawn is affected by the grubs or not. You can apply soapy water around the edges of the affected area. If grubs exist there they should surface 10 minutes or so. There is also a wet towel/carpet method you can apply to know your lawn condition. You can also apply it by seeing the suggested video below.

Let’s watch a video review from Lawn Solutions Australia to understand more about this one –


Grubs are the most dangerous evil for your beautiful lawn. If you’re facing grub activity, such as Japanese beetle grub, curl grub, army grub, or chafer grub, make a quick bold step against these.

Besides, it’s not only grubs that hurt your lawn. All the leaving big rust-colored pieces of dying grass will attract creatures like moles, raccoons, and skunks. They will try to tear up your lawn as they can feed on them.

So what’s the best grub killer for lawns for me?
