There is a product called Milk Spore or Milkey Spore, something to that affect that I picked up at local nursery. Its supposed to kill grubs and there larvae for up to 7 years. Its an organic powder, I do believe, and is safe to put on your lawn if you have kids and pets. You may want to check this out. I know damage to lawns by grubs, moles and other pests has been horrible in my area this year.
Milky Spore will only kill Japanese Beetle larva, not all species of white grubs.
It will take about 3 years to be effective.
 
To late in the season for Grub X.
Not to mention it only has a one month window for correct use.
The 2012 main ingredient in Grub X is generally used only when warranted for future control like fall. Not to be aplied during fall but from April 15 to May 15 because of it's ingredient having chelated properties and interaction with SOM. It will stick to the horizon's OM before reaching the grubs if applied past the window of opportunity
 
This thread has plenty of misinformation.

To the OP: Use dylox this time of year. It is the most effective

Products like grubex and merit must be timed correctly with the lifecycle of the grub. I would consider using one of these products next year as a preventative.

Merit and Grub X have differeing ingredients now.
he's got worms and birds.... : ]

I'd stray away from using long range residual insecticide poison with free ranging groceries on the same turf. The likes of grub x {W/2012 ingredient} are an unlikely candidate for control in the particular situation. Same with products containing Carbaryl which are more toxic. Pets kids and the like must stay off the lawn for at a minimum of 24 hours after aplication of Sevin. Chickens scratch when foraging etc etc. Bad idea IMO. on both products.

There has been considerable
debate among turfgrass entomologists about the use of insecticides such as Grubex that are designed to be used
before the size and damage potential of the insect population are known. That is, these products are applied
when the adult beetles are still flying, eggs not yet laid. There is a great potential for abuse of this product if
turf managers use it indiscriminately, that is, without regard to the likelihood of having damaging populations of
insects on treated areas some time in the future. Since white grub outbreaks tend to be localized and sporadic,
preventive control often results in areas being treated unnecessarily.
