If you live in Baringa, Beerwah, Landsborough, Nirimba, Beerburrum, Peachester, Bells Creek, Mooloolah Valley, or the Glass House Mountains, this blog is for you. In this blog, we're diving into the topic of lawn grubs and how to manage them to keep your lawn healthy and beautiful.

What Are Lawn Grubs?

Lawn grubs, also known as white grubs, are the larval stage of various beetles, including Japanese beetles, June beetles, and European chafers. These pests live in the soil and feed on the roots of grass, causing significant damage to your lawn. Signs of a grub infestation include brown patches of grass, spongy turf that pulls up easily, and an increase in animal activity as birds, raccoons, and skunks dig for grubs.

Identifying Lawn Grubs

Identifying lawn grubs involves inspecting your lawn for the following signs:
Brown or Dead Patches: Look for irregular brown or dead patches of grass.
Spongy Turf: The affected area may feel spongy or soft underfoot.
Increased Animal Activity: Animals such as birds and raccoons might dig up your lawn to feed on the grubs.
Grubs in the Soil: Dig up a small section of your lawn (about 30 cm square) and inspect the soil. Healthy lawns typically have 0-5 grubs per square foot. More than 10 grubs per square foot indicate a problem.

How to Manage Lawn Grubs

Managing lawn grubs requires a combination of preventative measures and treatment options. Here are some effective strategies:

1. Maintain a Healthy Lawn

A healthy lawn is more resistant to grub damage. Keep your grass well-watered, properly fertilized, and mow it at the correct height. Healthy grass can withstand minor grub infestations without significant damage.

2. Biological Control

Beneficial nematodes are microscopic worms that naturally kill grubs. These nematodes enter the grubs' bodies and release bacteria that infect and kill them. Apply nematodes to your lawn in the early morning or late evening when soil temperatures are moderate.

3. Milky Spore

Milky spore is a bacterial disease that specifically targets Japanese beetle grubs. Once applied to your lawn, the spores infect grubs and multiply, providing long-term control. This method can take a few years to become fully effective but offers lasting results.

4. Chemical Control

Chemical insecticides can provide immediate relief from severe grub infestations. Look for products containing ingredients such as imidacloprid or carbaryl. Apply these treatments according to the label instructions, usually in late summer or early fall when grubs are actively feeding.

5. Preventative Measures

Preventative treatments can help reduce the risk of future infestations. Apply a preventative insecticide in the spring or early summer before grub eggs hatch. This approach can help keep grub populations low and protect your lawn pest control Glass House Mountains from damage.

6. Watering Schedule

Adjust your watering schedule to make your lawn less attractive to beetles. Beetles prefer to lay eggs in moist soil, so watering your lawn deeply but infrequently can help deter them.

7. Regular Monitoring

Regularly monitor your lawn for signs of grub activity. Early detection allows you to take action before the infestation becomes severe. Check your lawn in early summer and fall for any signs of grubs or damage.
