Grass grub

I have a grub problem. I have removed all the dead grass from the large patch they killed. What do I do next?

I asked Reg Lewthwaite, one of our horticulture lecturers what he thought. Reg suggested that first of all you take the grub into a garden centre to get it identified properly (just to make sure it is grass grub). Once you have done this, you might be able to use one insecticide which is available to home gardeners. It is diazinon (a common material for spraying food plants and treating farm animals). It comes as a pellet and can be mixed into the soil.
