What stage do most grub control products target?

• A. Egg stage
• B. Larval stage (grubs)
• C. Pupal stage
• D. Adult beetles

Answer: (B)

Grub control products work best when the insects are actively feeding in the soil as larvae. Grubs are the white, C-shaped larvae of scarab beetles that live in the root zone and chew on grass roots, causing damage. The products are designed to reach these feeding larvae, either by being ingested or by contacting them in the soil. Eggs and pupae aren’t feeding and are harder to reach with typical turf treatments, and adults are above ground and not the stage these products target. So, targeting the larval stage captures the point where they’re feeding and vulnerable, providing the most effective control. Timing matters too—apply when grubs are young and actively feeding, usually late summer to early fall for many species.
