Grubs may be small, but they can cause big problems for your lawn. These tiny, C-shaped larvae of beetles (like the Japanese beetle and June bug) live beneath the surface and feast on grassroots, leading to weak, patchy turf. If left unchecked, a grub infestation can devastate your lawn, making it more vulnerable to weeds, drought, and further pest damage.
So, how do you know if you have a grub problem, and more importantly, how do you get rid of them? Let’s dig in.
Identifying Grub Damage
Grub damage can be sneaky at first, but there are some telltale signs to watch for:
- Brown, Patchy Grass – If your lawn has irregular dead spots that don’t respond to watering or fertilizer, grubs could be the culprit.
- Spongy Turf – Since grubs feed on grassroots, affected areas of your lawn may feel soft and pull up easily, almost like a loose carpet.
- Increased Animal Activity – Skunks, raccoons, and birds love to dig up grubs for a snack. If you’re noticing more of these critters tearing up your lawn, it’s a red flag.
- Grub Sightings – If you peel back a section of turf and find more than five to ten grubs per square foot, you’ve got an infestation that needs attention.
Effective Grub Control Strategies
Once you’ve confirmed grub activity, it’s time to take action. Here are the best approaches for prevention and treatment:
- Preventative Measures
- The best way to stop grubs is to prevent them from hatching in the first place. Applying preventative treatments in late spring to early summer can target young grubs before they begin feeding on your lawn’s roots. However, it is always important to check your local bylaws to ensure that the product your using is allowed for use in Ontario.
- Curative Approaches
- If grubs have already started feasting, a curative approach is needed. Treatments work best in late summer or early fall when grubs are still small and feeding near the surface.
