Inspecting for Lawn Grubs
An early indication that you may have a lawn grub problem is an increase in bird acitivty on your lawn. This is due to the birds consuming the Lawn Grubs.
If you can pull sod away from the ground, the root system may have been eaten by grubs. Cut into the soil and look for their presence. More than 100 grubs per square metre would mean you have a well-established population and quite a problem. Grub damage can also appear as small irregular patches of lawn appearing brown and dry.
Another way to check for grubs is to use a hessian bag or piece of old carpet and lay it on the grass in the late afternoon. Wet the bag or carpet thoroughly and leave overnight. The following morning the lawn grub will have been drawn to the surface.
Check your house eaves and fences for moths nests, if you find any of the white fluffy cocoon like nests hose and broom off. This will help prevent laying of the larvae and possible infestation
Keep your lawn mowed and groomed
After mowing, water your grass as this will encourage the grubs to move from the area

How to Kill Lawn Grubs
Mix Webzone Termiticide & Insecticide in water and apply evenly over the area to be treated using spray equipment. Apply at a rate of 12mL Webzone into 2L of water per 100m2. It is best to apply the solution after mowing to minimise loss of insecticide in clippings. Do Not apply to soils if excessively wet or immediately after
heavy rain. To ensure optimum control, after application, wet the treated area with up to 4 mm of water soon after application. Inspect treated areas for continuing activity, if activity continues re-apply as required.
