So far we are debating what to use before we put on new top soil and seed that area. I guess milky spore will be out because of experiences of previous posters. We my try the Grub EX. I have heard that the grubs prefer dryer areas and will leave the wetter ones alone.. I guess that must be true as they never touched the back, which is wet.

There are two type of grub control products. One kills the grubs as they are present and feeding. You would use that after seeing damage. I believe that one is called Dylox. The other one is a preventive, kills the grubs before they get to the feeding stage, and it has to be timed correctly or it will deteriorate before the grubs appear in your lawn. Beneficial nematodes are another option, but research them well, because when you see how you need to apply them (at night, in the rain is best!) you may opt to just use the Grub-X. If your grub feeding season seems to be over or is coming to an end, you can do nothing, or you can use the Dylox. The use a preventive product in late summer. That would contain Merit (imidacloprid), but you might alwo want to know that's the chemical most closely linked with pollinator deaths.
We always spot treated for grubs, treating areas that had been hit before. They seem to appear in the same spots from year to year. We have never treated a whole lawn for any pest, insect or weed.
