Practical tips
- Tug a brown patch gently; if the turf lifts easily with few roots, look just under the soil for C-shaped white grubs.
- Count grubs in a small square cut of sod before deciding on treatment; a few is normal for many lawns.
- Skunks, raccoons, or birds digging at night can be a sign grubs are present.
- Ask a local lawn pro about timing; treatment and overseeding work best when matched to the grub life cycle.
