How to Get Rid of Lawn Grubs (Natural & Organic Methods)

By Sabrina Wilson / July 27, 2022

Lawn grubs are small white or cream-coloured creatures that live in soil and feed on grass roots. They are the larvae of various types of beetles, including Japanese beetles, European chafers and May/June beetles. A single grub can eat up to half a metre of grass roots a day, which can severely damage or kill a lawn. In an infestation, grubs can quickly destroy a lawn, leaving behind brown patches of dead grass. Lawn grubs are most active in late summer and early fall, when they are mature and ready to pupate into adults. As they feed, they damage the grass, making it more susceptible to disease, pests and drought. lawn grubs can also make it difficult for new grass to establish itself, as the grubs will simply eat the new roots. Overall, lawn grubs can cause a great deal of damage to a lawn, and should be controlled as soon as possible.

Organic methods for getting rid of lawn grubs are preferable for several reasons. First, they are safer for children and pets, as well as for the environment. Second, they are usually more effective than chemical methods, since the grubs are not resistant to them. Third, they are more sustainable and eco-friendly, since they do not rely on artificial chemicals that can end up polluting the environment. Finally, organic methods are often less expensive than chemical ones, since you do not have to purchase expensive pesticides.

Beneficial Nematodes

If you're looking for a natural and effective way to get rid of lawn grubs, beneficial nematodes are a great option. Beneficial nematodes are tiny, parasitic insects that kill grubs by infecting them with bacteria. They're safe for people, pets, and the environment, and they're easy to use. Simply mixing them with water and sprinkle them over your lawn. You'll need to reapply them every few weeks, but you'll soon see a decrease in the grub population.

Neem Oil

To use neem oil to get rid of lawn grubs, mix 1 ounce of neem oil with 1 quart of water in a pump sprayer and apply evenly over your lawn. Repeat this process every 2 weeks until grubs are no longer present. Neem oil is a natural insecticide that will kill grubs without harming your lawn or other beneficial insects.

Insecticidal Soap

Insecticidal soap is made from the fatty acids of plants, typically coconut oil or palm oil. These oils are mixed with potassium hydroxide to create a soap that can break down the cell walls of insects. This soap is effective at killing most soft-bodied insects, such as aphids, but can also be used on harder-bodied insects, such as whiteflies. Insecticidal soap is typically used as a last resort, as it will also kill beneficial insects, such as bees and ladybugs.

Insecticidal soap is an effective and fast-acting solution for eliminating lawn grubs. Simply mix up a solution of insecticidal soap and water and soak the grubs in it for a few minutes. The soap will kill the grubs quickly and efficiently.

Horticultural Oil

Insecticidal soap is a special type of soap that is designed to kill insects. It is made with a very specific blend of ingredients that are known to be effective at killing a wide variety of insects. The most common ingredient in insecticidal soap is potassium salts of fatty acids, which are known to be highly effective at killing a wide range of insects. Other ingredients that are often used in insecticidal soap include oil of lemon eucalyptus, clove oil, and neem oil.

To get rid of lawn grubs, first mix 1 teaspoon of horticultural oil with 2 cups of water. Then, using a gardening syringe, inject the mixture into the grubs' holes. Be sure to do this in early morning or evening, when the temperature is cooler and the grubs are less active. Finally, water your lawn heavily to wash away any remaining grubs.
