UW-Extension says manual removal is best way to rid plants of Japanese beetle
The Portage County UW-Extension is warning homeowners about the presence of Japanese beetles.
According to a news release, the adult Japanese beetle feeds on over 300 varieties of fruits, vegetables, trees, shrubs and flowers, eating the soft tissue between the veins leaving a lace-like skeleton.
The beetles stick around through the end of summer.
According to UW-Madison Entomologist, Patrick Liesch, the best way to remove them from your garden and plants is to hand pick them from the plant. He stated the presence of beetles on a plant attracts more beetles. However, daily removal will reduce the number by half.
Beetles can be killed by putting them into a bucket of soapy water.
Liesch warns while beetle traps work, they do attract more beetle than normal to plants.
