Frequently Asked Questions FAQ

How often should I apply insecticide to my lawn?

This depends on the product and the type of pest you're dealing with. Some insecticides offer protection for several months, while others may require reapplication every few weeks. Always check the product label for specific application intervals and consult with a professional if you’re unsure about timing or dealing with a recurring infestation.

How do I get rid of pests that are killing my lawn?

Identify the pest first. Some of the common signs include brown patches, loose turf or visible insects like grubs or armyworms. Then, choose a lawn insecticide suited to that pest and apply it as directed. For severe infestations, a follow-up treatment may be needed.

How do you safely apply insecticides to your lawn?

Follow all label instructions carefully and avoid contact with skin and eyes, washing your hands after use. For liquids, calibrate your sprayer to ensure even coverage. For granular products, use a spreader or spread by hand, then lightly water the area. 

Will insecticides affect other plants on my lawn?

Most lawn insecticides target pests in the soil or turf and won't harm other garden plants when used correctly. However, it’s always best to avoid over-spraying onto garden beds or edible plants unless the product specifically says it’s safe.

What are the most common lawn pests in Australia?

Some of the most common pests include lawn armyworm, curl grubs (African black beetle larvae), funnel ants, billbug larvae, Argentine stem weevil and sod webworm, all of which can cause serious damage if left untreated.
