A Guide to the Most Common Turf Pests in Queensland

Queensland is renowned for its beautiful climate and stunning landscapes, whereby the climate creates the perfect conditions for lush and green turf.

However, along with the beautiful outdoor environment comes a range of turf pests that can cause extensive damage to your lawn. These pests can make your lawn look patchy, brown, and unhealthy if left untreated. In this blog, we’ll discuss the most common turf pests in Queensland and how you can get rid of them before it is too late.

While there are many types of turf pests here in Brisbane, below are the top pests with tips on how to identify them and remove them from your turf safely.

Armyworms: Armyworms are a type of moth larva that feed on grass blades, causing extensive damage to your lawn. You can identify armyworms by their greenish-grey colour and the stripes that run along their body. They’re most active during warm and humid weather conditions and are particularly prevalent during summer.

To treat armyworms, you will need to apply insecticides that contain the active ingredient bifenthrin or cypermethrin. It is important to apply the insecticide during the early morning or late afternoon when the armyworms are most active. Be sure to water your lawn before and after using the insecticide to help it really penetrate the soil for best results.

Black Beetle: Black beetles are one of the most common turf pests in Queensland. They feed on the roots of your lawn, causing significant damage and often killing the grass you and your family enjoy. You can identify black beetles by their black or dark brown colour and their hard shell-like exterior.

To treat black beetles, you will need to source and apply insecticides that contain the active ingredient imidacloprid or chlorantraniliprole. These chemicals work by disrupting the beetle’s central nervous system, which eventually leads to death. The beetles are most active during the spring or early summer so this is the ideal time to apply insecticide to your lawn. You need to water your lawn before and after applying the insecticide to help it penetrate the soil and to prevent any unwanted burning of your new turf.

Lawn Grubs: Lawn grubs are the larvae of several types of beetles, including the Japanese beetle and the scarab beetle. They feed on the roots of your lawn, causing it to die and turn brown. You can easily identify lawn grubs by their C-shaped body and their white or yellow colour.

To treat lawn grubs effectively, you will require insecticides that contain the active ingredient carbaryl or trichlorfon to apply to your turf. These chemicals work by killing the grubs before they can cause any significant damage to your grass.

Lawn grubs are similar to the black beetle as they are also most active during the spring or early summer which is the perfect time to apply the insecticide to get on top of them. You should also water your lawn before and after applying the insecticide to help it really penetrate the soil.

Sod Webworm: Sod webworms are the larvae of small brownish-grey moths. They feed on the grass blades, causing your new turf to turn brown and die. You can identify sod webworms by the small holes they leave in the lawn and the silken webbing they create on the grass blades.

Insecticides that contain the active ingredient carbaryl or bifenthrin are necessary to manage these turf pests. It works by killing the larvae before they can cause any significant damage to your lawn. It’s essential to apply the insecticide during the early morning or late afternoon when the sod webworms are most active which will also avoid burning your new turf in the hot sun. Watering your lawn before and after applying the insecticide is essential to ensure its effectiveness.

Mole Crickets: Mole crickets are a type of cricket that burrows through the soil, which can cause significant damage to your lawn’s roots. They are most active during the spring and summer months and can cause extensive damage to your turf if left untreated.

To treat mole crickets effectively, apply insecticides that contain the active ingredient carbaryl or bifenthrin. The insecticide works by killing the mole crickets before they can cause any significant damage to your lawn. Avoid applying the insecticide in the middle of the day when the sun is at its strongest as this can cause burning of your lawn.
