The problem with the honey bees is when they gather nectar and pollen from treated plants. In this case you will likely be treating your lawn and not flowering trees and bushes which should limit the exposure to the honey bees. The other option would be to use Milky Spore
to control the grubs. Milky Spore is not harmful to anything except for Japanese beetle grubs. Milky Spore Powder is a natural, safe, effective grub control product that can remain in the soil for up to twenty years. This is an OMRI certified organic control of Japanese beetle grub control that is safe to use with other herbicides and insecticides that is safe to use around birds, bees, pets and fish and around pools and ponds. Milky Spore Powder contains Bacillus popillae, a bacterium that kills grubs by multiplying inside the grubs, causing them to die. The spores are then dispersed in nearby soil, which is how the product is able to exist in your soil for so long and even comes with a ten-year guarantee.
