Japanese beetle larvae live in the soil feeding on tender grass roots. Milky Spore is a bacterium that infects and kills grubs. You apply milky spore to your lawn and water it in so grubs become infected by swallowing a spore when feeding on grass roots. The grub is killed 7 to 21 days later. As the grub decomposes billions of new spores will be introduced into the soil from one grub.
Milky Spore is approved by the EPA. It is a safe material to kill grubs. It is not toxic to insects, birds, pets or humans. It will not affect wells, ponds or streams. Also, it is harmless for food crops.
As the spores multiply in your soil, they spread to cover the entire lawn. As time passes, the spores will spread to neighboring lawns. This bacterium becomes more effective over time and has a life span of 15 years.
Important! Make sure to purchase the Lawn and Garden Milky Spore Powder Dispenser for application! *Sold Separately*
"One of my favorite places to get plants! The people there are always friendly and helpful. They are pet friendly, so I always bring my dog. She can be a bit much to handle in public, so I don’t take her out often. BUT whenever I go to Bath the people there always help me out with her! Every time I go to Bath I leave happier and with a new plant!"
