I live in Columbia. Large areas of my lawn have turned brown and roll up like carpet. When do grubs lay their eggs and what is the best time to treat my lawn to get rid of them. Is it too late in the year to put down a treatment?

Hi - It is too late to put down grub control products now; grubs will be deep in the soi at this time of year. Grub controls are best applied as a preventative between mid-June through August. Look for a season-long grub control that contains the active ingredient Chlorantraniliprole. This product is more environmentally friendly than some others on the market. See our publication on Japanese beetles for more information, https://extension.umd.edu/hgic/topics/japanese-beetles.
