The thick grass is attractive to the grubs. As soon as the grubs hatch, a healthy root system is what they feed on. The more severe your lawn damage will be, the higher the concentration of larvae.

Why does my grass 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. Many homeowners suspect grub damage in the early spring because of the condition of their lawns. Grubs are small insects that feed on the roots of grasses and other plants.
They are not harmful to humans or pets, but they can cause damage to your lawn if you don’t take steps to control them. If you suspect that your grass is infested with grubs, contact your local Extension office for help.
What causes grubs to come out of the ground?
When grubs go to town on the roots of your grass, the lawn dies and can often be peeled off the ground. Grubs can also be found under the bark of trees and shrubs.
If you have a tree or shrub in your yard, you may notice that it is covered with a thin layer of grub poop. This is a sign that the tree is being eaten by a grubby insect.
Grubs are attracted to the smell of rotting food and they will eat anything they can get their mitts on.
Do grubs come back every year?
The grubs come back up to the surface in early may after tunneling deep in the soil for the winter. In early to mid- June, the grubs build an in-ground “cocoon” and transform into beetles that emerge from the soil and start to feed on the roots of the plants.
June and early July, when the beetles are ready to pupate, they come out of their cocoons and begin to eat the leaves and stems of plants that have not yet been damaged by the winter. This is the time of year when plants are most vulnerable to frost damage and are at their most susceptible to disease.
If you have plants in your garden that are in good condition, you should be able to plant them again in late summer or early fall. However, if your plants have been in poor condition for a long period of time, it may be difficult to get them to grow back to their full potential.
Will grub damaged lawn grow back?
Grass can be damaged and killed by grub counts from six to 10 per square foot. If you have a grub problem, treat it with beneficial nematodes or pesticides that are allowed in your area. It is best to repair your grub-damaged lawn in the fall or early spring.
Do grubs leave holes lawn?
They will strip away your grass or dig tunnels underneath in search for one of their favorite delicacies. Birds and other animals dig your lawn to find earthworms. Before embarking on a grub hunt, be sure to confirm that grubs are present.
Where do grub worms come from?
Japanese beetles lay their eggs in the summer in sunny areas of the lawn.
To take care of this problem, you need to know how to detect grub worms and when to apply pesticides. Japanese beetles are the most common cause of lawn beetle infestations, but they are not the only culprits.
Other insects, such as grasshoppers and aphids, are also responsible for infesting lawns, and they can be controlled with the same methods as grubs.
Do coffee grounds attract grubs?
Many gardeners use coffee grounds in their garden to give their garden an added boost of fertilization, but be warned; this can end up attracting more grubs to your garden. If left unaddressed, the grub worms will quickly take over your lawn.
Coffee grounds can also be used as a natural insect repellent. Coffee grounds are a good source of calcium, magnesium, potassium, and manganese. They are also rich in vitamins A, C, E, K, B1 and B2.
What is the best time to treat for grubs?
The best time to treat is in the late summer or early fall, when the grubs are most vulnerable to the worms. The best time to treat is during the first few weeks of June or July. This is the time when most of the larvae are still in the pupal stage, so they are less likely to be eaten by predators.
If you do not have access to a garden hose, you can use a spray bottle filled with water and a few drops of an insecticide such as DEET or picaridin. The spray should be applied in a well-ventilated area and should not be allowed to sit for more than a minute or two before rinsing off. You can also apply the spray directly to the soil, which will help to kill any remaining larvae that may be present.
