In the end you have to measure your level of tolerance. You can have grubs and beetles and not necesarily have a problem. But if the damage level does require action,,, then the options are not pretty.

You'd have to pull out the big guns for that. I hate the thought of putting chemicals on my yard.

But if someone was in the position that they had to do something, I would recomend doing a good amount of research. Grubs are a tough problem and it's going to take more strategy and planning than picking up a bag of Home Depot grub control.

Fact is, depending on the grub you have, you may not be able to get rid of it.

Ick.

I think there isn't really any effective way even if we were able to kill all the grubs in our lawn. Problem is that they can come from anywere. :(

I use a pyrethrin-type spray at regular intervals, usually applied at night to minimize effects on bees. The deterrent effect lasts for several days. I avoid Sevin because it's more toxic to humans and can leave whitish deposits on leaves.
