Lawn eating Chafer Grubs

We are approaching the time when you can apply nematodes for the control of Chafer grubs. They are normally applied late July - Sept. The Chafer grubs need to be in the lawn i.e just under the grass surface. You need to ensure the lawn is moist and water it afterwards for a number of days. This ensures that the nematodes can move through the soil to infect and kill the chafer grubs. You will most likely have to do the treatment each year for a few years until the local population is reduced. Harrod sell the product as Nemasys Chafer Grub Killer. I hope this helps.
