African Black Beetles...

I couldn't figure out why my lawn looked so dead and was drying out all the time, but I think I have discovered african black beetles in my kikuyu lawn. Can I use Confidor Hose-On now even though the bugs have already began devouring my lawn? Will it damage the grass any more than already is already done? Also, is it ok to hose in after rain and or after hosing seasol into the lawn? Thanks in advance...

Answer: Dear Rod.

The damage you are seeing in your lawn would be from the larvae of the African Black Beetle (the curl grub) This grub is present in lawn from mid spring to mid summer. The adult beetle lays the eggs in the soft soil in early spring, the young larvae feed on dead organic matter in the soil and the older larvae feed on the grass roots.

Confidor Hose-On Insecticide should be used on the young larvae from mid spring to mid summer. Once you have applied the product it should be watered in thoroughly afterwards. It is too late to use this product now as it is likely that this grub has gone into the pupal stage and is now emerging as a beetle. Baythroid Lawn Grub and Garden Insecticide is the product to use now to control the African Black Beetle. Neither of these products will damage your lawn.

To encourage the grass to grow and self repair where the areas are bare, applications of Nature’s Way Seaweed Booster as well as a good lawn fertiliser (Dynamic Lifter Advanced for Lawns) will help your grass to recover.

This lawn pest seems to appear every year and needs to be detected early. By spraying your lawn in spring with Confidor Hose-On Insecticide you will be able to eliminate the curl grub and save your lawn from being damaged.

Good luck in elimating this nuisance pest. I am sure you will have your lawn area looking good again before we go into the winter months.
