Lawn Grubs: What are they, how to get rid of them.
Lawn grubs are a seasonal problem in the south east of Queensland from around November to May. This year after the heavy rainfall experienced, Morton bay residents are reporting that their lawns which were lush and green are now being devastated by lawn grubs.
What do Lawn Grubs eat?
Lawn grubs feed on the roots of grass in your lawn. As the lawn grub population increases the lawn will start to die off in patches. The infection will increase until the lawn dies or the lawn grub is treated successfully.
What damage can Lawn Grubs cause?
Lawn grubs can have a devastating impact on your lawn in a short period of time. Signs of lawn grub include:
- Large masses of birds on your lawn
- Chewed leaves
- Patches of dead grass with no thatch layer
- Evidence of grub or beetle in thatch layer
- Moths on the lawn area at dawn and dusk
- Moth eggs under the eve of your home
- Sightings of a small orange wasp dancing above the lawn, this usual indicate lawn grubs are present, as the wasp is looking for a host to lay its egg.
Treating Lawn Grubs
If you believe you have lawn grubs you will need to have your lawn treated, with a follow up treatment in seven to 10 days to help break the life cycle.
