Lawn Pest Control Services in Perth (Armyworm & Beetle)

Stop lawn pests before they strip your turf.

Lawn Pest Control Services

You spend all year watering, mowing, and feeding your lawn, only to walk out one morning and see huge brown patches appearing overnight. Or perhaps your lawn feels loose, like a rug that isn’t attached to the floor. These are the classic signs of a pest attack.

In Perth’s warm climate, lawn pests like Lawn Armyworm and Black African Beetle are aggressive and destructive. They can destroy a healthy lawn in a matter of days if left untreated.

BYRNE Turf & Maintenance (BTM) provides rapid-response pest control for residential lawns. We don’t just spray and pray; we identify the exact pest, use the correct commercial-grade insecticide to break the breeding cycle, and help your lawn recover from the damage.

Call us immediately if you suspect pests. Speed is everything.

The "Big Two" Lawn Killers in Perth

Lawn Armyworm (The Surface Destroyer)

Armyworms are caterpillar-like larvae that move in huge numbers (like an army), eating the leaf blade of your grass.

Signs: You will see eaten leaves (transparent tips), green droppings (frass) on the ground, and birds pecking at the lawn. Damage usually starts near outdoor lights or trees and spreads rapidly.

Speed: They feed at night and can strip a lush green lawn back to dirt in less than 48 hours.

Test: Throw a wet towel on the lawn overnight. In the morning, lift it up—if you see caterpillars underneath, you have an infestation.

Killer Two

Black African Beetle (The Root Destroyer)

These are even more dangerous because the damage happens underground. The beetle larvae (white curl grubs) eat the roots of the grass.

Signs: The lawn turns yellow or brown in patches. Crucially, the grass pulls up easily like a toupee because it has no roots left to hold it down.

Season: The grubs are most active in late Spring and Summer.

Impact: Because the roots are gone, the lawn cannot drink water. It essentially dies of thirst, no matter how much you irrigate.

Ant Control

Ant Control (Coopex / Fipronil)

Ants are less deadly to the grass but can ruin the look and usability of your lawn.

Funnel Ants: They create mounds of dirt that ruin your levels and blunt your mower blades.

Bull Ants: Aggressive and dangerous for kids and pets.

Coastal Brown Ants: They undermine paving and brickwork.

We can apply granular or liquid ant treatments that wipe out the colony, not just the ants you see on the surface.

We treat common Perth lawn pests including Lawn Beetle / Black Beetle, whose larvae (white curl grubs) feed on the roots and leave irregular dead patches that lift up like loose carpet. Armyworm are fast‑moving caterpillars that can strip a lawn from green to brown in as little as 48 hours if they are not controlled promptly. Mounding ants also cause problems by pushing up soil, ruining levels, creating uneven areas underfoot, and smothering the grass beneath their constant activity.

Prevention vs Cure (Acelepryn)

The smartest way to handle lawn pests is to stop them before they establish, rather than waiting until you see brown patches and thinning turf. A preventative program using Acelepryn puts a protective layer in the soil that targets grubs and caterpillars as they hatch and begin feeding, giving you peace of mind through the main growing months. With a single, well-timed application, you can dramatically reduce the risk of sudden lawn collapse caused by unseen insect activity.

Acelepryn is considered a gold-standard product because it offers long-lasting control—up to six months of protection—without the harsh side effects of many traditional insecticides. It is highly targeted in the way it works and has very low toxicity for bees, birds, and pets, making it a safer choice around families and high-use lawns. In many cases, one application in spring is enough to protect your lawn for the entire season, so you enjoy healthy, even growth without constant re-treatments or emergency call-outs.

  • Safe: It is highly targeted and has very low toxicity for bees, birds, and pets.

  • Effective: One application in Spring can protect your lawn for the entire season.

Lawn Pest Control Frequently Asked Questions

Is the spray safe for my dog/cat?

We use professional products that typically require you to keep pets off the lawn until the spray has completely dried (usually 1–2 hours). Once dry, it is safe. We will always give you specific safety instructions on the day.

Will the grass grow back after Armyworm?

Yes, usually. Armyworms eat the leaf, not the root. If we catch it early and feed the lawn, it will bounce back quickly.

Will the grass grow back after Beetle damage?

This is harder. If the roots are gone, the grass often dies completely. This is why preventative treatment or early detection is vital.

Can I just use the hose-on stuff from Bunnings?

You can try, but the concentration is much lower. For a heavy infestation, you might knock them down but not kill the cycle. Professional application ensures the right dose reaches the right depth.
