Reseeding + Grub Preventer: Wrong Product, Wrong Time

Homeowner seeded patches 2 days ago. Sees grubs on walkway edges. Bought Bayer Grub Preventer. Okay to apply?

No. Preventer (imidacloprid) stops *future* grubs (eggs → larvae). Does nothing for current grubs. Won't hurt seed, but wastes money.

Correct sequence:

**Now:** 24-hour grub killer (Bayer Dylox/trichlorfon) for active grubs
**Next June:** Preventer (imidacloprid or chlorantraniliprole) for next generation

Match product to life stage. Preventer ≠ cure.
