How to control Armyworm

The second type of lawn grub is the armyworm. These army-coloured, khaki-green caterpillars are the larvae of moths of the Noctuidae family. They are a nuisance throughout Queensland and New South Wales and sometimes occur in plague proportions. Armyworm consume the leaves, stems and seed heads of grass. They can decimate entire lawn areas, leaving behind practically nothing but bare earth.

How to detect armyworm

If you notice patches of lawn suddenly dying, this could be evidence of armyworm activity. You may also notice small, grey moths flying around your lawn. (These moths are armyworms in their adult stage, looking for a place to lay their eggs.)
