They ate up about 20% of my st augustine in spite of the fact I used Scotts Grubex and Aloft. I could NEVER find any significant grubs at any time although the yard kept going into decline. So I ripped up a section got some aloft and put the zoysia sod down in Sept. Now for some reason the zoysiz didn't take so I lifted a piece to see if there was any roots and found 5 of these little guys playing dead. I took em and put em under the hot light and away they went.
HOw do I get em good
