Long-Term Japanese Beetle Grub Control — Naturally
If Japanese beetle grubs are destroying your lawn, turf, or landscape, Milky Spore Powder offers a proven, organic solution. This 50 lb kit — two 25 lb drums — contains Paenibacillus popilliae, a naturally occurring bacterium that specifically targets Japanese beetle grubs in the soil before they emerge as destructive adults. Apply once, and let nature do the rest.
Key Benefits
- Long-lasting grub control — targets Japanese beetle larvae at the soil-dwelling stage before they cause surface damage
- Self-perpetuating action — once grubs ingest the spores, the bacterium continues to propagate in the soil while grubs remain active
- Safe for people, pets, and beneficial insects — highly target-specific with no known impact on non-target organisms
- Safe around food crops — can be applied in vegetable gardens, orchards, and edible landscapes
- Compatible with most fertilizers, pesticides, and herbicides — fits into existing lawn and garden programs
- Unaffected by freezing or adverse weather — remains viable through seasonal temperature extremes
- Bulk value — 50 lb kit covers large properties, farms, golf courses, and commercial turf

Why Choose Milky Spore Powder?
Milky Spore has been trusted by organic growers and turf professionals for decades. Unlike broad-spectrum chemical insecticides, it works exclusively on Japanese beetle grubs — leaving earthworms, pollinators, and other beneficial soil organisms unharmed. It requires no repeat annual applications once established in the soil, making it a cost-effective, low-labor solution for large properties. The 50 lb bulk kit is ideal for anyone managing significant acreage who wants reliable, long-term results.
Pro Tip: Pair with beneficial nematodes (NemaSeek) for enhanced grub control, especially in high-pressure situations or during initial establishment.
