Lawn grubs, also known as white grubs, are the larvae of various beetles and can wreak havoc on your lawn by feeding on grass roots.

In this guide, we’ll explore the best lawn grub killer Australia  how to identify a grub infestation, and tips for proper application and prevention.

Identifying Lawn Grub Infestations

Before applying a lawn grub killer, it’s important to confirm the presence of grubs. Common signs of a grub infestation include:

• Brown or Dead Patches: Irregular brown patches that can be easily pulled up due to root damage.
• Increased Animal Activity: Birds, raccoons, and other animals digging in your lawn to feed on grubs.
• Spongy Turf: The turf feels spongy underfoot due to root damage.

4. Application Method: Use a spreader for granular products to ensure even coverage. For liquid concentrates, use a garden sprayer and apply evenly across the lawn.
5. Safety Precautions: Wear protective clothing, gloves, and a mask during application. Keep pets and children off the lawn until the product has been watered in and the grass is dry.

In addition to treating existing infestations, taking preventive measures can help protect your lawn from future grub problems:

• Healthy Lawn Maintenance: Regular mowing, watering, and fertilizing can keep your lawn healthy and more resistant to pests.
