How to Get Rid of Grub Worms

Worms have been around for a long period. They can be seen in every type of environment, including fresh water and snow. There are approximately 4,000 different species of worms that exist on our planet, which is more than any other animal group in the world. Most types of worms are not harmful to people affecting only certain insects. However, grubs are the larval form of beetles, and they can cause millions of dollars worth of damage to crops each year. If left untreated, grub infestations kill plants and make them more susceptible to disease and damage from future pests.

If you have a garden, then you know that grub worms can be a major nuisance. These little critters can wreak havoc on your plants, and they can be difficult to get rid of. On this page we will discuss how to get rid of grub worms using natural methods. We will provide some tips on preventing them from coming back in the future. So if you are dealing with a grub worm infestation, read on for some helpful advice.

What are grub worms?

A grub worm is an insect larva that is the larval form of scarab beetles. Grubs have cylindrical bodies, thick skin, and no legs or antennae. They are small, white, and C-shaped. The head of the grub is an elongation of the body which has mouthparts and hook-like claws. Based on the size of the grub and other factors, this larva stage can last anywhere from a few weeks up to a year before it turns into an adult beetle.

Grub worms are common lawn and garden pests. They can be found in both soil and water. They are most commonly found in areas that have been disturbed, such as gardens and lawns.

They come in different colors, but most are black, brown, or grayish-white. Grub worms thrive during spring when warm days and the soil is moist.

Signs of grub worm infestation

If you see any of the following signs, then you likely have a grub worm infestation:

  • Wilted plants
  • Dying grass patches
  • Circles of dead grass
  • Mud tubes on or near the surface of the soil

When to treat grubs

The best time to treat grubs is in early spring before the eggs hatch into larvae. If you wait until later spring or summer, you risk killing beneficial insects such as bees and butterflies pollinating flowers and plants. You also run the danger of treating too late because by then some types of grubs will have already laid their eggs in the soil.

In order to determine when to treat grubs, take a look at your lawn frequently during spring. Examine the grass closely to ensure that you catch any infestation early enough to treat it without harming your property and landscaping. One way to do so is by looking at the underside of leaves for white grubs.

What can I do to get rid of grub worms?

There are several methods that you can use to get rid of grub worms. The following are a few of the most effective techniques:

Check for beetle activity

If you notice a lot of beetles around, it is likely that there are grubs being produced as well. They tend to fly around in large numbers in search of areas where they will lay their eggs. Look out for flying beetles late in the evening or early morning when they’re attracted to light sources such as porch lights and streetlights. Once you notice beetles flying around these areas, turn off all unnecessary lights at night so they won’t be attracted and pollinate your lawn instead of laying their eggs.

Apply milky spore powder to your lawn to control grubs

Milky spore powder is a natural product that can be used to control grubs. The spores will penetrate the soil and infect the larval stage of the grub, eventually

killing them. It may take a few weeks for the milky spore powder to take effect, but it is a long-term solution that will continue to kill grubs for several years.

Treat your lawn with nematode spray to get rid of grub worms

You can also use nematodes, which are tiny parasitic worms, to control grub worm populations. Nematodes can be applied through irrigation systems or as a soil drench. They kill the grubs by entering their bodies and releasing bacteria that cause them to die from septic shock. You can buy them online or at garden stores.

Nematode sprays can be purchased at most garden stores and are easy to apply. They should be watered into the lawn and will take effect within a few days.

Remove grubs manually

If the population of grub worms is not too large, you can remove them by hand. This can be a tedious process, but it is an effective way to get rid of them if they are only present in small numbers.

Use a chemical grub killer

If you have a large population of grubs or the other methods don’t seem to be working, you may need to resort to using a chemical grub killer. There are several types available, so be sure to read the label carefully and follow all instructions. Always wear gloves and protective clothing when applying any type of chemical.


Rototilling is a process where you till the soil with a rotary tiller. This will disrupt the life cycle of the grubs and kill them.  It is an effective way to get rid of grubs, but it will also kill the grass in the area. You may need to reseed the lawn after rototilling.


Solarization is a process where you heat up the soil by using solar energy. This will kill the grubs and any eggs they may have laid.  It is a long-term solution, but it can take several weeks for the soil to heat up enough to kill the grubs.

Soil Amendments

Adding organic matter, such as compost or manure, to your soil will help to improve its structure and make it less hospitable for grub worms. 

One option is to add lime to the soil, making it less hospitable for grubs. Another thing that you can do is add sand or grit to the soil; this will help make it harder for the grubs to move around and survive. You can also add organic matter to the soil, such as compost or manure, which will help to keep the soil healthy and make it less appealing to grubs. Finally, you can try using a nematode spray; these microscopic worms will attack the grubs in your lawn and hopefully get rid of them.

Cover your lawn with plastic

This can also be an effective solution to get rid of a large population of grub worms. You can cover your lawn with plastic to suffocate them. This is only a temporary solution, but it will kill the grubs quickly. Be sure to remove the plastic once the grubs are dead.

How can I prevent grub worm infestations?

Grub worms will eat up all the nutrients in the soil, so they need to be removed before they continue to thrive. Remove as many as you can but don’t waste time waiting for them all to come out because they will just keep coming back until there is nothing left for them in the soil.

  • First, try to remove any debris or objects that might be providing a home for grub worms.
  • Eliminate excess moisture by repairing leaky faucets and fixing drainage problems.
  • Make sure your lawn is mowed regularly and kept free of clippings.
  • Finally, you can use pesticides to get rid of grub worms, but always follow the instructions on the label carefully. Never apply more pesticide than is recommended, and never use it in areas where children or pets might come into contact with it.

Having a lawn and garden of your own is a great privilege, but having grubs in it can be quite disheartening. These things develop in several garden plants, and they aim to devour virtually everything in the plant. The worst thing about it is that it does not kill the plant itself but simply forces it to grow poor crops. Aside from this, these worms have been known to carry diseases that can be harmful to humans as well.

Getting grub worms out of the lawn is much quicker and easier than you might think. As soon as you notice them, get after them with these simple methods to eliminate these pests for good.
