We're currently battling a racoon who is tearing up our lawn in big clumps. Were told that he is going after grubs that live in the soil beneath the lawn. We've tried trapping the racoon, but he's too smart for that! Please advise.

Raccoons love to peel up the soil to look for grubs. Once they find a stash they tend to come back for more. Sampling for grubs is a good first step in determining whether or not that's what the raccoon is finding. You can cut a square foot of turf out, pull it up and look on the soil surface and on the roots for fat, white grubs; less than six grubs per square foot can usually be masked by water and fertilizers. Populations between 10 and 15 per square foot can cause significant turf damage in September and October. Of course, populations occasionally reach 40 to 60 grubs per square foot and these levels can cause significant damage to your lawn, as well as attracting raccoons. If you find grubs you can treat your lawn with a product like Grubex or Bayer Advanced Season-Long Grub Control granules, applied according to label directions.
