Are you sure you have grubs? You could have brown patch which you really don't need to do anything for. Only way to be sure is a soil test.
If it is grubs you can often tell by rolling back the the sod like a piece of carpet to expose them. As far as control, that's best done in August when they're feeding near the surface. Here are links to information. But before you apply any other chemicals, I'd take a soil sample so you know what you're dealing with.
