If you’ve noticed some pests chomping away at your garden in July, check to see if they’re Japanese beetles. July is the month when adults emerge from the soil, feed, mate and lay eggs, according to the University of Minnesota Extension Service.

These pests will be most active throughout July and August. The live only about 60 days, but can do much damage in that time.

The Japanese beetle was introduced to the United States from its native Japan in 1916. In the eastern United States, protozoans that live in the soil are a natural predator that keep the beetle under control. However, these protozoans are not present in Minnesota soil. So it’s up to gardeners to take care of them.

Because Tonkadale Greenhouse recommends green solutions for pests, we sell Bonide’s Japanese Beetle Bagger Kits. These kits use a pheromone to attract the beetles, which then fall into a bag and are trap there. One kit protects 5,000 square feet.

Each kit includes:

  • 1 set of interlocking vanes
  • 1 dual lure system with a  natural sex attractant and proven floral lure
  • 2 bags
  • 1 hang tie

The bags are perforated so they don’t collect water. Replacement lures and bags can also be purchased separately.
