Cream-white, C-shaped larvae with a tan head capsule and three pairs of legs near the head. Range from 10–40 mm depending on species and instar. Found in the soil 1–3 inches below the turf.
Soil under turf across all Florida lawn types. Adult beetles fly and lay eggs in summer; larvae feed on roots through fall and winter before pupating.
- Turf that can be pulled up in mats because roots have been eaten away
- Spongy, irregular brown patches that don't respond to watering
- Raccoons, armadillos and birds digging up the lawn — a reliable grub indicator
- White larvae revealed when brown turf is peeled back
Grubs destroy the root system of Bermuda, Bahia and St. Augustine grass, and the secondary damage from wildlife digging for them can devastate a lawn. Heavy infestations can require complete turf replacement.
Rhino's lawn program applies preventive and curative grub treatments timed to larval development, stopping damage before it becomes visible and protecting the root zone year-round.
