Most Common Lawn Pests

Having a perfect lawn is a dream many homeowners strive for. While managing all the basics, including watering, mowing, and fertilising, is fairly straight forward, there’s one aspect of lawn care that’s less easy to control – lawn pests.

Lawn pests can be numerous and varied. For example, underground, your grass could become a meal for White Curl Grubs and Mole Crickets.

Other lawn insects, including Armyworms and Two Spotted Mites, could attack the stalks of your favourite turf grass.

With a little understanding of the different lawn pests that exist within your area, you can easily keep them under control with good lawn management or an effective pre or post-emergent insecticide.

Wondering what pests may be the problem? read on for a comprehensive list of Common Lawn Pests and solutions to get rid of them!

Top 10 Most Common Lawn Pests & Treatment

MOLE CRICKETS

mole cricket

What Are Mole Crickets?

The Mole Cricket is a brown elongated insect pest with a hard, shiny head, wings and a body up to 50mm long.

They possess large front legs with jagged claws for digging, and powerful hind legs that are used for removing loose soil while burrowing.

Female Mole Crickets lay their eggs from the beginning of November throughout the warmer months.

The adult male Mole Cricket dies after mating and the females die after laying their eggs. 

Mole Crickets are most prevalent in your lawn from mid to late spring until the end of summer and prefer the habitat of moist soil.

How to Control Mole Crickets?

To protect your lawn from Mole Crickets, keep it well feed with a good fertiliser.

As soon as you see signs of Mole Crickets myhomeTURF recommends a suitable insecticide for long-term residual control that has the Common Active Ingredient Abamectin.

myhomeTURF recommends Thumper, an effective insecticide that can be purchased through our Partner Lawn Pride.

army worm

ARMY WORMS

What are Army Worms?

Army Worms are caterpillar grub pests found in lawns.

Army Worms vary in colour from green to brown to black, can reach a maximum length of about 40mm, and will become plump as they feed and mature.

Large numbers of Army Worms are possible due to their moth parent being able to lay up to 500 eggs in a single laying, and then repeat the same process the following night.

These lawn grubs get their name because they form large armies, devastate large areas of lawn, and then quickly move onto the next lawn.

Ideal weather conditions during summer and autumn can see Army Worms appear in plague proportions where they leave brown patches all over your grass.

How to Control Army Worms?

Army Worms are very difficult to find, they spend their days hiding at soil level, and deep inside the thatch layer of the lawn.

It’s at night that Army Worms will come out and spend their entire night feeding on your lawn.

Once Army Worms have been identified, they are treated with a lawn insecticide that has the Common Active Ingredient Chlorantraniliprole.

myhomeTURF recommends using Acelepryn, an effective insecticide that can be purchased through our Partner Lawn Pride.

cutworm

CUTWORM

What are Cutworms?

Cutworm is a caterpillar-like pest and is typically yellow, green, brown or grey and has stripes.

The larval stage of Cutworm appears as a smooth bodied, dark coloured caterpillar with longitudinal lines and brown to black spots on back and sides.

When mature the adult black Cutworm metamorphoses into a brown moth with a wingspan up to 55mm.

Adult moths lay their eggs in clusters in grass at night and are attracted to the light, making lawn surfaces around night-lit buildings more susceptible.

Cutworm larvae hatch and usually feed on the lawn during the night and take shelter during the day. 

These larvae typically cut off your lawn’s leaves at the crown level and pull them into a burrow before feeding hence the name Cutworm. 

Cutworms have two generations per year and overwinter as pupae in your lawn. 

Some species of Cutworm produce enough generations so adult moths are present throughout the year.

Conditions favouring Cutworms on your lawn are pro-longed summers, early-autumns and humid weather.

How to Control Cutworms?

To control the Cutworms myhomeTURF recommends a suitable insecticide with the Common Active Ingredient Chlorantraniliprole for long-term residual control.

myhomeTURF recommends using Acelepryn, an effective insecticide that can be purchased through our Partner Lawn Pride.

The earliest damage of White Curl Grubs will appear as patches of turf which seem to be dying off with an appearance of the drying out of the lawn’s leaf.

As damage to your lawn from the White Curl Grub progresses you will be able to pull up your lawn easily from the soil as the roots have been severed away.

ant on blade of grassANTS

Some Info about Ants

Ants can be beneficial in your lawn by moving organic material into the soil, creating tunnels and aerating the soil.

Ants, however, can cause cosmetic damage to your lawn as they create tunnels and mounds of excavated soil on the lawn’s surface.

Ants are small, long and thin insects ranging in size from 1-50 mm in length and vary in colours of black, brown, yellow, and are sometimes metallic.

Ants prefer well-drained soil in lawns that is not compacted – so healthy lawns are not removed from ant damage.

How to Control Ants in your Lawn?

Homemade Ant killer is an option and can be done by simply pouring boiling water onto the Ants nest that is on your lawn. This homemade method can take several attempts and result in wet, boggy areas in your lawn as well as cause your grass to turn brown through scalding.

Using both dishwashing detergent and olive oil to control Ants in your lawn is another option, however, this can have detrimental affects to your lawn by making the treated section paler in colour.

There are other homemade methods but, myhomeTURF also recommends a suitable insecticide for long-term residual control that has the Common Active Ingredient Fipronil.

myhomeTURF recommends Fipronil, an effective insecticide that can be purchased through our Partner Lawn Pride.

About Grasshoppers

Grasshoppers are large, hard-bodied, chewing insects, typically 50mm to 120mm+ long with two large compound eyes provided for quick reflexes.

A Grasshopper’s powerful hindlegs which are used for jumping make a snapping noise, as do their wings.

During the day, male Grasshoppers make a chirping sound produced by rubbing their legs and wings together.

Female Grasshoppers lay eggs in either the ground or on leaves of grass, their eggs then hatch into nymphs (young) that grow through various stages similar in appearance to adult forms, often developing wings in adulthood. 

There are many different species of Grasshoppers that can cause damage to your lawn, generally in colours of greens, browns and blacks, sometimes in oranges, blues, and reds, all in varying patterns.

Grasshoppers can be found hiding in the ground, on stems or on leaves of your lawn and cause the most damage from spring until autumn.

As soon as you see signs of Grasshoppers damaging your lawn myhomeTURF recommends a suitable insecticide for long-term residual control that has the Common Active Ingredient Bifenthrin.
