Try Yates Grub Kill and Protect for the control of Black Cutworm larvae in lawns. All treatments are way more effective if you can catch an infestation in its early stages. Regular monitoring of your lawn and garden will ensure that a major infestation of Cutworms doesn’t occur ‘overnight’. There are several things that you can do to prevent serious damage from Cutworms (see How to Prevent Cutworms Appearing). Prevention is always better than cure, and you are more likely to be able to achieve that if you are out and about in your garden regularly.
If you find insects you will need to know what Cutworms look like (see Description). If you find damage you should have a closer look to see if you can find some insects. For this to work you will need to know what to look for (see Symptoms of Cutworm Damage).

The secret to pest control is to keep an eye on your plants, including your lawn, so that you can detect pest incursions early. Larvae feed on a wide range of plants including lawn grasses, vegetables and ornamentals (especially at seedling stage), and broadleaf weeds. The adult moths of Cutworms are completely harmless and feed on nectar from flowers. Black Cutworm is thought to be resident in warmer sub-tropical and tropical parts of Australia, and migrate into southern regions during the warmer months there. Pink Cutworm and Black Cutworm are found throughout Australia. A significant number of the adults (‘Bogong Moths’) in south-eastern Australia migrate to mountainous country to shelter over summer. Black Cutworm aka Greasy Cutworm ( Agrotis ipsilon)Ĭommon Cutworm is found in the southern half of Australia, including Tasmania.
