What is GrubGone and How It Works
GrubGone is a soil-applied grub control product that targets the larval stage of beetles responsible for lawn damage. Once applied and watered in, the active ingredients move into the root zone where grubs feed. When ingested or contacted, the product disrupts their life cycle and reduces infestation levels.
Key benefits include:
- Targets grubs below the soil surface
- Helps prevent root destruction
- Reduces brown patches and turf thinning
- Works as both preventive and curative control (depending on timing)
- Safe for most established lawns when used correctly
Why Spreader Settings Matter
Using the correct spreader setting ensures:
- Even distribution of the product across the lawn
- Proper dosage per square meter
- Prevention of over-application (which can waste product)
- Avoidance of under-application (which reduces effectiveness)
- Reduced risk of lawn striping or patchy results
Incorrect settings are one of the main reasons grub control treatments fail, even when high-quality products are used.
Best Conditions for Applying GrubGone
For best results, always consider environmental conditions before application:
- Apply when the soil is slightly moist, not dry or waterlogged
- Avoid application during heavy rain or strong winds
- Mow the lawn 1–2 days before treatment for better coverage
- Water immediately after application (essential step)
- Apply during active grub periods (spring to late summer, depending on region)
