Once they find a lawn they are happy with, they will lay huge clumps of eggs. These will hatch within 2 to 5 days becoming grub larvae, better known as caterpillars. It is this stage of the lifecycle that you will find the most damage is dealt to your lawn. They will chew through your lawn for about 18 to 24 days until they finally become pupae and then about a week later, moths.

So, what are the signs of lawn grubs?

• Increased bird activity on your lawn shows they’ve clued onto the increased amount of snacking opportunities on your lawn.
• Seeing greyish-brown moths flying around, especially at dusk, is a sure sign they are scoping out your lawn.
• Brown patches of lawn that can be easily lifted from the ground indicate that lawn grubs have chewed through the roots of that area.
• Or, a spongy lawn. A spongy lawn can also indicate thatch build up but it’s definitely worth checking a grub infestation isn’t the issue.
