Grub Control
What is a grub?
Grubs are small, soft-bodied, and white or cream-colored, with a distinct C-shaped body. They have a brownish head and three pairs of legs near the head and are typically found in the first few inches of soil. Grubs are the larval stage of several insect species, particularly beetles. In upstate NY, Japanese beetle and June beetle are two major species encountered.
Why are grubs bad?
Grubs eat away at the root system of our beloved lawns. A healthy lawn can tolerate some level of grub activity but a high population can cause large dead patches where the exposed turf becomes loose or spongey and can be easily pulled up. Often, other animals that feed on grubs will add another layer of damage to turf.
How many grubs are too many?
Grubs are considered a pest when they reach populations high enough to cause visible dead spots in the lawn. While it depends on the overall health of the turf, generally, more than 10 grubs in one square foot is a problem. You can count for yourself - measure out a square foot at the edge of a dead spot where it transitions to health turf and dig away.
How to deal with a grub infestation
There are a couple methods you can use to deal with a grub infestation on your own before applying pesticides:
- Mow correctly. Keeping grass 3-4" high will promote healthy roots and will also shade the soil, making less appealing to egg-laying beetles.
- Water properly. Avoid overwatering, as soggy soil attracts egg-laying beetles. Water deeply but infrequently (about 1 inch per week) to encourage deep root growth.
If you are still having trouble, give us a call. We can confirm the infestation and utilize appropriate chemical controls.
