How to Apply Milky Spore Powder Using the Lawn & Garden Dispenser Tube (sold separately)

Protect your lawn naturally with Milky Spore, an effective solution for controlling Japanese beetle grubs before they mature into destructive adults. Once applied, the beneficial Bacillus popilliae spores multiply and remain active in the soil, providing years of continuous protection. Safe for use around pets, beneficial insects, and the environment, this easy-to-apply treatment covers up to 2,500 sq. ft. for dependable, long-lasting lawn care.

Japanese beetle grubs feed on grass roots below the surface before damage is visible. Early treatment helps protect lawns before adult beetles emerge.

Beneficial spores establish themselves in the soil, creating lasting protection that continues working below ground season after season.

The easy application pattern helps achieve even coverage across your lawn, making treatments quick, consistent, and easy for homeowners.

Protecting grass roots from grub feeding helps maintain a thicker, healthier lawn that can better withstand everyday outdoor activity.

Milky Spore doesn’t just kill grubs, it builds a natural defense system in your lawn. Once applied, the spores multiply as grubs ingest them, creating a self-sustaining cycle of protection. Over time, your soil becomes naturally fortified, helping to reduce future infestations for years to come with minimal maintenance.

It’s a smart choice for gardeners who care about pollinator safety and overall soil health.

Milky Spore is powered by Bacillus popilliae, a naturally occurring bacterium that specifically affects Japanese beetle larvae. It’s a targeted, biological solution that aligns with organic gardening practices while being highly effective at reducing grub populations.
