Introduction
Lawn grubs, also known as white grubs, are a common pest in Australian lawns. These destructive insects can cause significant damage by feeding on the roots of grass, leading to brown patches and weakened turf. To maintain a healthy, vibrant lawn, it’s essential to identify and effectively treat lawn grub infestations. This guide explores the best lawn grub killers Australia, their benefits, and tips for application to help you protect your lawn.
Understanding Lawn Grubs
Lawn grubs are the larval stage of various beetles, including African black beetles, Argentinian scarabs, and curl grubs. These larvae feed on grass roots, causing the grass to become thin, yellow, and eventually die off in patches. Common signs of a lawn grub infestation include:
- Brown or dead patches in your lawn.
- Grass that feels spongy or lifts easily from the soil.
- Increased bird activity as they feed on the grubs.
