Grub damage is by far the most common type of damage sustained in turf grasses throughout the United States. Customers who choose to add grub control to their scheduled services will receive it along with control of all turf feeding and subsurface feeding insects. White grubs and many other subsurface feeding insects usually go unnoticed until the results of their feeding on the root system in your lawn are observed in late August and into early fall.
An active population can easily destroy your lawn in a very short period of time. In addition to these subsurface feeding insects causing damage themselves, their presence tends to attract animals, such as birds, mice, rats, gophers, groundhogs, raccoons and skunks, who love to feed on an active grub population; ultimately, causing even further damage to your lawn.

Grub Control – FAQ’s
- Grub Control
- 1. When does grub damage occur and when is the best time for a grub control application?
White grubs, the larval stage of beetles, come out of the ground in early June and return back into the ground in August. It is at this time when they return back into the ground that they do their destruction by feeding heavily on grass roots before they barrel deeper into the ground. Late August and throughout September is the prime time for grub damage. We treat for grubs late May thru Mid-July typically during our 4th lawn care treatment, which provides season long control of grubs.
- 2. Are only white grubs controlled with this service?
We use a commercial grade insecticide that is the industry's longest lasting residual control for all types of subsurface and turf feeding pests. Some of the most common subsurface and turf feeding pests controlled are: Billbugs, European crane flies, hairy chinch bugs, mole crickets, white grubs, including black turfgrass ataenius beetles, European chafers, Japanese beetles, May and June beetles, Northern masked chafers, Oriental beetles, Southern masked chafers.
- 3. How can I tell if I have grub damage?
Grub damage can happen almost overnight, where your lawn looked great and next thing you know it turns brown. The best way to test for grub damage is by pulling on the grass plant, if it comes up easy with no roots chances are you have grub worm damage.
- 4. Will a grub control application prevent me from getting moles in my lawn?
No, moles have two food sources: grubs and earthworms. By eliminating half of their food source it will push moles to look for food that is more plentiful elsewhere, but if your lawn has a good source of earthworms you still may get moles.
- 5. One morning I looked out over my lawn and noticed square patches of sod cut out and rolled back, what happened here?
In addition to the grubs causing damage themselves, their presence tends to attract animals, such as moles, voles, birds, mice, rats, gophers, groundhogs, raccoons and skunks, who love to feed on an active grub population; thus, causing further damage to your lawn. In this particular case, it sounds as if the lawn has been victimized by a skunk; they do just that, cut square patches of sod and roll it back to get to the grub worms.
- 6. My neighbor doesn't take care of their lawn and this year I had major grub damage and they didn't, why?
When beetles look for places to return back into the ground they look for a plentiful food source to feast on. If your neighbor doesn't take care of their lawn, it is like your neighbor is offering bologna for them to eat but you are offering steak, chances are they are coming to your lawn for dinner and not your neighbors.
- 7. I didn't get a grub control application this year and my lawn died off in about 1 week and now there are grubs everywhere just below the surface of the ground. Is there anything I can do at this point?
Yes, for starters a granular insecticide needs to be applied to your lawn ASAP! This will need to be watered in, thus making it effective, which will kill off the grub population. Then the excess dead grass should be raked up and removed; then your lawn will be ready for re-seeding.
