As a horticulturist with years of experience in lawn care and pest management, I've encountered various signs that indicate the presence of grubs in a lawn. Here's how you can identify if you have a grub infestation:
1. Damaged Lawn: The most obvious sign is a lawn that looks as if it's been chewed. Large patches of grass may be lifted or rolled back, revealing the soil underneath.
2. Irregular Brown Spots: Grubs feed on the roots of grass, which can cause irregular brown patches that may seem to appear overnight.
3. Bird Activity: Birds like starlings and robins often dig up grubs, so if you see a lot of bird activity in your lawn, it could be a sign of grubs.
4. Standing Water: If your lawn has areas that consistently hold water after a rainstorm, it might be a sign of grub damage because the soil structure is compromised.
5. Mushrooms: The presence of mushrooms can indicate grubs because the fungi often grow in the decaying organic matter that grubs create as they feed.
6. Earthworms: While earthworms aren't a direct sign of grubs, an absence of earthworms can be a sign because grubs can outcompete them for food.
7.
Physical Examination: The most definitive way to check for grubs is to physically examine the soil. Dig a few holes in different areas of your lawn and look for the grubs, which are typically white and C-shaped.
If you find that you do have grubs, it's important to take action to protect your lawn and prevent further damage.

To check, lift a piece of your turf. If grubs are the culprit, the dead patch will roll up like a carpet, or you'll be able to pull up the grass and see that it has no roots. Irregularly shaped dead patches appear in your well-irrigated lawn in late summer or early fall.
