Grubs – In Fescue Sod

Q: We are getting ready to plant fescue sod. When we were taking core samples we discovered a couple of white grubs. What should we do?

A: The right answer is: do nothing. It’s true that high numbers of grubs can damage grass roots but finding just a few is no reason for concern. Fescue can tolerate eight grubs per square foot with no visible effect. The ones left in your lawn will likely die this winter. I my opinion, grub control products are vastly over-sold and overused.
