A Guide to the Most Common Lawn Pests

lawn pestsHaving 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!

African Black Beetle

What are African Black Beetles?

The African Black Beetle is a shiny jet-black scarab soil-dwelling pest, up to 15mm long, with serrated front legs and looks very similar to a cockchafer.

African Black Beetle’s larvae are white to creamy-white, soft bodied curl grubs up to 25mm long.

The most active time of the year for African Black Beetles in your lawn is during spring and summer.

The female African Black Beetle can lay up to 80 eggs that hatch in 2 to 5 weeks.

How to Control African Black Beetles

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

Ants

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

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.

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.

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.
