Milky Spore Powder, manufactured by St. Gabriel Organics, is a select one time application and ready to use powder that targets the larvae of Japanese Beetles. 

Contains the active ingredient Bacillus Papilliae 0.02 %, which is a natural bacterial that will not harm other insects when feeding on the product or food crops. Once ingested the spores within this product will quickly multiply inside the grub killing it from within. Another unexpected benefit is it helps to rid your lawn of unsightly brown spots.

Milky Spore Powder provides a long term Japanese beetle grub solution for up to 20 years making it an economical product. Safe to use on grassy areas at any point in the season and remains dormant until feeding activity begins ensuring the next wave of infestation is eliminated. 

Tools Needed

Milky Spore Powder is a ready to use product that can be used right out of the container. You may also need a dispenser tube to release the powder from the container more easily.

How to Use

• Step 1: Locate areas where insects are traveling and hiding and then calculate the size of the area you wish to treat in square feet. To do this, measure the length and width of the treatment area in feet then multiply them together (length x width = square footage). Milky Spore Powder is recommended to be applied at a rate of one level teaspoon every 4 feet along rows four feet apart on the ground between plants or top of grass. Apply 10 oz. of product to treat a 2,500 sq. ft. area. For 4,000 sq. ft. use 1 pound of Milky Spore Powder. For 10,000 sq. ft. use 2.5 lbs. of Milky Spore Powder. For one acre of lawn use 10 pounds of this product.
• Step 2: Evenly shake the Milky Spore Powder from the container or dispenser tube until plants and grass have an even coverage on the top of leaves and on the ground in between plants. Once applied water the powder in gently for about fifteen minutes.

Where to Use

Milky Spore Powder can be used on lawns, grassy areas, ornamental gardens, flower beds, mulched beds, and ground cover beds.

When to Use

Milky Spore Powder can be used anytime of the year when the ground is not frozen. Typically this will be in spring or summer, when insect activity is most frequent. Apply on calm, warm days when rain is not expected for 24 hours.

Safety Information

Milky Spore Powder is safe to use around children or pets when applied according to the product label. Always make sure to wear the appropriate personal protective equipment (PPE) when mixing or applying this product.

Special Considerations

Uniform, highly efficient control cannot be expected until the entire treatment area including the ground between grass and plants has been treated with Milky Spore Powder. Reapplications may be necessary if not properly applied or the product being blown or washed away by rainfall within 24 hours of application.
