Your grape vines can be completely ruined if infested by Japanese Beetles. A sign that they are attacking your grape vines is the skeletonizing of the leaves of your grape plants. The Japanese Beetle will eat away at the leaves of the grape plant from the middle of the plant outward avoiding the veins, leaving your grape leaves looking like skeletons. To kill Japanese beetles on grape plants you must first kill the adult beetles and then attack their grubs.
Things You'll Need
Spectracide Bag-A-Bug
Warm water
Dish Soap
Glass jar or bowl
Milky spore
Milky spore dispenser tube
Prepare a mixture of warm water and soap in a glass jar or bowl.
Go out to your grape vines right before dusk and flick all of the Japanese Beetles that you find off of the leaves into the warm water and soap mixture.
Assemble the Spectracide Bag-A-Bug Japanese Beetle traps and hang one downwind and another close to where your grape vines are growing.
Fill your dispenser tube with milky spore. The milky spore will kill the Japanese beetle grubs.
Open the tube and apply a teaspoon of milky spore every four feet of lawn.
Allow the milky spore to absorb into the soil before watering or cutting your lawn.
Tips & Warnings
Milky spore is safe for pets, plants and humans.
Reapply milky spore to your lawn in spring, summer and fall.
Change the Spectracide bag once it contains over one hundred beetles.
Even though milky spore is safe for pets, humans and your yard, you still do not want to ingest it.
