Apply Grub Control Pesticide
Grub control insecticides that contain bifenthrin, imidacloprid, or carbaryl are very effective at killing grubs in an already established lawn. Insecticides containing these active ingredients such as GrubEx, Merit, and Sevin are mostly systemic and kill when they come in contact with the grub worms.
There are liquid grub killers and granular grub killers on the market. Therefore, to get rid of grubs in your lawn, do the following:
- For granular pesticides, apply using the regular garden spreader and water the treatment into the soil to kill the grubs.
- For liquid grub killers, mix with water according to the label and spray the infested areas thoroughly to ensure the pesticide goes deep into the soil.
It is important to choose the best, most effective grub killer for this purpose. Scotts GrubEx is one of the industrys most trusted grubworm destroyers.

Timing is key
When using a pesticide to control grubs, you have two options: a grub preventer, or a grub killer.
Grub killers act almost immediately, meaning you need to apply them as soon as you see lawn damage from grub worm activity. But for grub preventers, they have a lasting effect and mostly prevent grubs from the next season.
As such, make sure you apply grub control at the right time as per this guide and the label of the insecticide youre using.
Use Neem Oil Or Azadirachtin
Azadirachtin is a component of neem oil. While many people think neem oil and Azadirachtin are the same things, neem oil contains very little Azadirachtin.
As such, people usually buy concentrated Azadirachtin to use on their lawns. According to one study, Azadirachtin application on Kentucky bluegrass killed Japanese beetles at 5x the products label rate.
Neem oil is another pest control option. Pure neem oil deters the grubs from feeding, growing, and laying eggs. For best results, mix neem oil with water and spray the diluted solution on affected areas.
Cons: Both neem oil and Azadirachtin require regular reapplication despite its efficacy at killing larval Japanese beetles, Azadirachtin wont kill mature beetles or deter them from laying eggs.
What Do Grubs Look Like
You likely wont see grubs unless you go digging since they live beneath the surface. They are the larvae of Japanese beetles and are white in color with brown heads. Up to one inch in length, they look a bit like caterpillars. Their parents, the adult beetles, deposit their eggs beneath the surface of the soil so when they hatch and turn into grubs, they can use the roots of your turfgrass as food. When these grubs reach adulthood, they no longer look like caterpillars and instead look like beetles with metallic green heads and bodies. The adult beetles will dine on the grass above the surface while their larvae destroy it from below, which is why being proactive and calling your pest control service is so important.
Grubs and their adult parents create a two-front battleground for your grass, and if you dont do something about it, you could have extensive lawn damage. Unfortunately, many homeowners dont realize that the garden-variety beetles they see are actually producing the dreaded lawn grubs. Our experts will help you identify if youve got a grub problem on your hands.

What Chemical Products Can I Use To Control Grubs In My Lawn
If you have a severe grub infestation and want to use a chemical product to control grubs, you have a number of widely available options.
From about late April into early June, you can effectively use a product with the active ingredient chlorantraniliprole to control all species of white grubs we have in New Hampshire. This chemical also controls caterpillars such as webworms and armyworms. This product is most effective when the grub is actively feeding so applying it 2 to 3 months in advance of severe grub feeding from June to August is recommended. This ingredient is in two widely available products: GrubEx® and Roundup® For Lawns Bug Destroyer. The U.S. EPA designates this chemical as a low risk pesticide due to its low toxicity to bees and other beneficial insects.
Some products registered for controlling grubs just have a pyrethroid, such as products with the active ingredient Gamma-Cyhalothrin, commonly found in the Spectracide® Triazicide® Insect Killer For Lawns. According to research from Michigan State University, products that only contain lambda-cyhalothrin, gamma-cyhalothrin, bifenthrin, deltamethrin, cyfluthrin or permethrin do not work for grub control.
In most cases, whether its early spring or fall, its preferable to simply wait until the next appropriate window for using a preventative product that gets better results and is more targeted. Learn more about current insecticide approaches for white grubs from UMass Extension.
How Can I Control Grubs While Protecting Bees And Other Pollinators
Before applying any insecticides, the lawn should be mowed prior to application so there arent weeds flowering in the lawn while the product is being applied.
Also be conscious of drift. If its windy and you spray an area of your lawn, theres a chance the product could drift onto flowering plants nearby. Likewise, if youre using a spreader for a granular product, ensure you limit your application to lawn areas that have been mowed and do have a grub infestation.
Theres little reason to apply any of these products to your entire lawn if only a section of the lawn has a grub infestation. Only use chemicals to control grubs if necessary, and always follow all instructions on the label.

Signs Of Grubs In Your Yard
Noticing sponginess after watering your lawn? Finding brown patches in the middle of green? Grubs do their damage by eating the roots of your grass. With how rapidly grubs can spread, this can become an issue – fast. The presence of grubs can also bring along other problems. Birds, raccoons, and moles are just a few animals that are attracted to grubs because they eat them. Unfortunately, this doesn’t mean that they’ll just eat the grubs and kill them for you. While theyre looking for the grubs, theyll tear up your grass in the process.
Often times, grubs will have become a problem before you even spot them. Their eggs are typically laid late summer, and after hatching, they begin feasting. The grubs feed all throughout the fall. If you dont catch them when they start doing damage, you may end up having dead patches until next season. With this in mind, its better to inspect your lawn or call a professional earlier rather than later if you think you might have a grub problem.

How Do I Know If I Have Grubs
Many lawn issues that resemble grub damage can be caused by something else, including disease, drought stress, hairy chinch bugs, sod webworms, shade, compaction, and more. In the early spring, for example, many homeowners suspect grub damage because of the condition of their lawn after snow melt.
The only way to be sure that you have grubs is to scout for them in your lawn.
Depending on the size of your lawn, you may want to scout for grubs in several places in the lawn. Just because there are a lot of grubs, or not a lot of grubs, in a particular square foot doesnt mean that the entire lawn either does or doesnt have a grub infestation. You can focus your scouting on areas of the lawn that are showing symptoms of grub feeding.
As youre scouting for grubs in your lawn, take notes so you remember which areas of your lawn have high counts and which dont. This is important if and when you decide to treat the lawn.

Beneficial Nematodes Can Kill Other Soil Pests Too
By inoculating your garden soil with beneficial nematodes, youre likely killing several birds with one stone! And by birds, I mean pests. The strain of beneficial nematodes we use can effectively control many other pests including: cutworms, fungus gnats, fire ants, weevils, root maggots, flea larvae, crane flies, white grubs, and many more!
One study even showed that the beneficial nematodes also help reduce the population of root-knot nematodes in soil. We previously had an issue with root knot nematodes in our garden soil, and that has seemingly gone away with the grubs too! Other species of nematodes target different pests. For example, Steinernema carpocapsae Is great for organic flea control. As discussed in our introduction to organic pest control series, it is always important to identify your garden pests before acting.
If you have a pet, dont fret! Beneficial nematodes are not harmful to anything except their target pest species. They will not harm mammals, aquatic life, birds, reptiles or amphibians. When applied correctly, beneficial nematodes should not negatively impact beneficial insects such as ladybugs, who have very different above-ground life cycles. They do not harm earthworms either!
