Grubs: What Are They and What to Do

May 6, 2022

What are grubs?


Grubs are June bug larvae.

June bugs will lay hundred of eggs in late spring/early summer. These white grub larvae will then hatch and happily feed on the roots of your lawn, causing the grass to easily be pulled loose due to the damaged roots.  

Grubs are large C-shaped beetle larvae that feed on roots of turf grass plants. These grubs are white, up to 1 inch (2.5 cm) in length, with dark translucent dorsal stripes, brown head capsules and legs 




Grubs feed on the thatch layer of the grass, resulting in irregular dead patches. Symptoms resemble drought stress and persist even where there is sufficient irrigation. By August, patches of dead grass may also appear throughout your lawn, wilting suddenly and erasing any hard work put into maintaining your landscape. Additionally, these grubs serve as the perfect source of food for pesky racoons, boars, and moles.  These critters will then add their share of damage as they gobble up the delicious white grubs. 


You can prevent some damage from raccoons by placing fruit netting over your lawns. They have very sensitive paws so the texture of the fruit netting is often enough to deter them from peeling up your lawn. We can help assist with mole activity with our mole control service. As for boars, unfortunately there isn’t much that can be done besides getting rid of the grubs.

We find it best to do a preventative treatment for grubs in late May or early June. This is because the eggs will have just been laid and the treatment we perform prevents them from maturing into adult June bugs. We do offer an emergency fall treatment if there are grubs present in your lawn as well. These treatments are included in our Lawn Care Program!
