How to control armyworms
In large numbers, armyworm can advance like an army (hence their name), strip the turf foliage and cause rapidly expanding bare patches.
Curl grubs are the larvae of beetles, like the African Black Beetle. Sometimes they are incorrectly referred to as ‘witchetty grubs’, they are C-shaped creamy coloured grubs that live in the soil and eat through the roots of your prized lawn.
In addition to bare patches, if you see birds pecking at the lawn, it can be a sign that lawn armyworm and curl grubs are present (the birds are searching for the caterpillars).
