In a bid to combat the pesky Japanese beetles, a natural biological control called Milky Spore Powder has gained attention. This powder, containing the bacterium Paenibacillus popilliae, is specifically designed to target Japanese beetle grubs in the soil.
When the grubs ingest this bacterium, they develop a milky white appearance and eventually perish, helping to reduce the population of Japanese beetles over time[2][3]. However, it's important to note that the effectiveness of Milky Spore in controlling Japanese beetles is limited and inconsistent.
The bacterium's survival, reproduction, and ability to infect grubs under suitable soil and temperature conditions can vary widely. Milky Spore is effective only against Japanese beetle grubs (not adults or other grub species), and its persistence through cold winters, especially in northern climates, is often limited, thus affecting long-term control. Coordinated neighborhood use is often necessary to see notable population suppression[1].
Multiple university studies, such as those from the University of Connecticut, University of Vermont, and Cornell University, have shown inconsistent or relatively poor field results for Milky Spore[1]. In contrast, alternative products like beetleGONE! contain other beneficial bacteria that target a broader range of grubs and beetle life stages and are less dependent on specific soil conditions.
When using Milky Spore Powder, it's crucial to follow the application instructions. The powder should be applied to the soil near the base of the affected plants, but not on plants that are in bloom or are about to bloom[1].
Milky Spore Powder is available in three sizes: 10 oz, 40 oz, and a 40 oz option is suggested for larger infestations of Japanese beetles. For treating a small infestation, the 10 oz size is recommended[1].

- Transitioning from pest control, creating raised beds in your home-and-garden could provide a safe haven for beneficial insects and plants, contributing to a more balanced lifestyle in your garden.
- Incorporating home-and-garden practices like maintaining raised beds can help diversify the types of organisms present, reducing the reliance on single solutions like Milky Spore Powder for Japanese beetle control.
