The Army Is Coming!

Lawn armyworm are caterpillars of night-flying moths which lay their eggs amongst turf leaves. The caterpillars grow up to 4cm long and range in colour from green to brown, with darker and paler stripes running along their back and sides. Adult moths are brown and attracted to lights at night.

There can be multiple generations of armyworm in a year, with caterpillars being most active during summer and autumn. In large numbers, armyworm can advance like an army (hence their name), strip the turf foliage and cause rapidly expanding bare patches.

In addition to bare patches, if you see birds pecking at the lawn, it can be a sign that lawn armyworm are present (the birds are searching for the caterpillars).

Yates Baythroid Lawn & Garden Insecticide is a concentrated formula that will control common lawn pests like armyworm. See back of pack for details on dilution rates.

Water the lawn both before and after applying, to help move the insecticide down into the thatch where the armyworm can hide.

And there’s no need for a brown and crispy lawn during summer! Providing the lawn with adequate water and nutrients will help keep it looking lush and green throughout the warmer months. Here’s how:

In the tropics and sub-tropics during summer’s wet weather, delay fertilising until the drier months arrive. And during January, using a soil wetter and aerating or coring the lawn can help to move the rainfall down into the soil, rather than sitting on the lawn surface, which can encourage diseases.
