Grub control — preventative
Season-ahead grub product, before larvae are large enough to chew roots.
Timing An hour, plus watering in
Typical months: Apr, May, Jun, Jul
Before larvae are large. Exact month depends on the active (April vs early summer) — read the label.
Soil gate: Soil temp unknown — Using calendar windows only
your lawn: Preventative products need to be down before larvae are large. Japanese beetle timing varies; the label’s window wins.
Why
Preventative actives need time to work. Waiting until the lawn peels up is a different job.
Steps
- Apply in the product’s window (often April–June; some actives want earlier).
- Water in so the material reaches the root zone.
- Keep a note of what you used — curative products are a different chemistry later.
What you need
Equipment
- Broadcast spreader
- PPE — gloves, eye protection, long sleeves
Buy before you start
- Preventative grub granule (imidacloprid or chlorantraniliprole type)
How much

Caveats
- Preventative and curative bags are not interchangeable. Match the timing to the active.
- If you had no grub history, this is optional — not every lawn needs an annual insecticide.
