Signs Of Grub Worms In Lawn
A lawn thats developing brown patches and showing signs of weakening could be suffering from disease. Fungal infections commonly produce brown spots, but even white grubs in your lawn can cause similar signs.
Here are signs of grubs in your lawn and how to check for these destructive worms:
- Dead patches in the lawn: Youll observe patches of brown or dead spots as the grass starts to thin out, turn yellow, and die. This occurs because grubs feed on roots, thus killing your turfgrass easily. Check out this great article I did on other causes of brown patches in lawns.
- A spongy turf: Grubs will damage the roots of turfgrass, leaving the grass easy to pull and roll up just like carpet. To test this symptom, you can do a tug test on your grass to see if it pulls up too easily.
- Increased raccoon and bird activity: Birds, moles, and raccoons feed on worms and other insects in the lawn. If you notice theres increased activity of these predators digging your lawn, it could be a sign there are grubs in your lawn.
- Presence of many grubs in the soil: A major sign of grub infestation in your lawn is the presence of the milky-white, C-shaped worms in soil samples cut from your yard. A few of these pests shouldnt stress your grass, but a large number of them can cause serious damage. More than 5 grubs per square foot of lawn soil will produce symptoms of white grub damage.

TheEuropean chafer and Japanese beetle larvae are especially notorious when it comes to destroying lawns and they also represent the biggest grub worm beetle threat in North America.
Grub infested turf is at its worst around August. This is the part of their life cycle when they start to surface, destroying pretty much anything they can get to grow up and finish their metamorphosis.
The fact that the grub worm is destroying roots and anything it can find in the ground areas is bad as it is, but they bring another negative aspect with them. That is the other predatory animals that like to feast of them.
This can be a very bad combination for your lawn and the grubs living in the garden. The damage will be doubled if you let these happen.

Use a Garden Rake
Use your garden rake to get rid of the brown, affected spots and remove the dead grass. Make sure to rake the damaged area a bit more to remove the extra thatch and loose soil.
Sprinkle Grass Seeds
The next thing you can do is sprinkle new grass seeds over the raked area. We recommend sprinkling 10-15 seeds per square inch for a completely bald area and 5-10 seeds per square inch for a semi-bald area. Sprinkle less if the surrounding turf is healthy
Tamp the Seeds
Once youve sprinkled enough grass seeds, tamp them with your foot. Next, it is good to sprinkle topsoil over the grass seeds.
Water Your Lawn
Lightly water your lawn every day until the grass is a few inches tall. It is recommendable to water every day for two-three weeks.

Grub Killer Vs Grub Prevention
The lifecycle of grubs, also called grub worms, begins when the grub worms from last year appear as June bugs, also called Japanese beetles. This happens in the spring between May and June. While the Japanese beetles do not harm turf grass, they will damage trees and ornamentals as they feed on them.
June bugs and adult beetles lay eggs in healthy lawns. The eggs hatch in the summer and become white grub larvae. Those are the grubs that are going to damage your lawn. They feed on your lawn from July and September.
As winter moves in, the soil starts to freeze, and any grub worms that have survived bury deep into the soil and put themselves in a vegetative state over winter. When springs rolls in the next year, the newly hatched grubs come out of the soil as beetles around May to June. And so the life cycle of white grubs and June bug beetles continues.
As the grubs feed on your grassroots during the summer and fall, you will see irregular patterns of brown patches all over your lawn. You will also be able to peel your grass back like a carpet. You can see the grubs around the edges of the damaged turf.

Heres a good test, from the University of California Integrated Pest Management Program: Pull up about 1 square foot of the earth around the base of your sod . If you notice more than 6 grubs in this space, its a good time to consider preventive methods or treatments to reduce overpopulation.
Shetlar, however, recommended that lawn lovers should be even more vigilant, especially in order to prevent large critters from eating them. When talking about the maximum threshold of tolerance for grubs, I always chuckle about , in that skunks and raccoons havent read about this threshold.
As such, it may be worthwhile for homeowners to be just a little warier on account of skunks and raccoons. Shetlar added, If there are four to five grubs per square foot, thats usually enough for them to be digging around.
