How to Deal with Lawn Grubs in Summer: Effective Solutions
Lawn grubs, the larvae of various beetles, can wreak havoc on your lawn during the summer months. These pests feed on grass roots, leading to brown patches and weakened turf. If left untreated, a grub infestation can cause extensive damage to your lawn. In this blog, we’ll explore how to identify and effectively deal with lawn grubs in summer, ensuring your grass remains healthy and green.
Identifying Lawn Grubs
Before you can tackle the problem, you need to confirm that grubs are the cause of your lawn issues. Look for these signs:
Brown Patches: Irregularly shaped brown or dead patches that don’t improve with watering.
Soft, Spongy Turf: Grass that feels soft or spongy when walked on, indicating root damage.
Increased Wildlife Activity: Birds, skunks, and raccoons digging in your lawn, searching for grubs.
Pull Test: If you can easily pull up sections of grass, exposing white, C-shaped grubs underneath, you have an infestation.
Effective Solutions for Dealing with Lawn Grubs
Once you’ve identified a grub problem, it’s time to take action. Here are some effective solutions to manage and eliminate lawn grubs:
1. Biological Control
Beneficial Nematodes: These microscopic worms are natural predators of grubs. Apply nematodes to your lawn according to the manufacturer’s instructions. They will seek out and infect grubs, effectively reducing their population.
Milky Spore: This naturally occurring bacterium targets and kills grub larvae. While milky spore can take a couple of years to establish, it provides long-term control by multiplying in the soil and infecting future generations of grubs.
2. Chemical Control
Insecticides: Use a targeted insecticide labeled for grub control, such as imidacloprid or chlorantraniliprole. Apply these products in late summer when grubs are actively feeding near the soil surface. Follow all label instructions for safe and effective application.
Preventive Treatments: If you’ve had grub issues in the past, consider using a preventive insecticide in early summer. These treatments target newly hatched grubs before they cause significant damage.
3. Cultural Control
Proper Lawn Maintenance: Healthy lawns are more resilient to grub damage. Maintain a robust lawn care routine that includes regular mowing, watering, and fertilization.
Aeration: Aerating your lawn can improve soil drainage and reduce compaction, making it less attractive to grubs.
Overseeding: Fill in bare spots with overseeding to promote thick, healthy turf that can better withstand grub infestations.
4. Natural Predators
Encouraging natural predators, such as birds, to visit your lawn can help control grub populations. Install bird feeders and bird baths to attract insect-eating birds that will feast on grubs.
Preventing Future Grub Infestations
Preventing grub infestations is just as important as treating them. Follow these tips to keep your lawn grub-free:
Monitor Regularly: Regularly inspect your lawn for signs of grub activity, especially in late summer and early fall.
Maintain Healthy Soil: Healthy soil supports a healthy lawn. Conduct soil tests and amend your soil with organic matter as needed.
Water Wisely: Avoid overwatering your lawn, as excessive moisture can attract beetles to lay eggs. Water deeply but infrequently to promote deep root growth.

Dealing with lawn grubs in summer requires a combination of biological, chemical, and cultural controls. By identifying the signs early and taking proactive steps, you can protect your lawn from these destructive pests and enjoy a lush, green yard all season long.
