The weather guessers lied.
Our local news said last week that we wouldn't be seeing Japanese beetles this season since they didn't make it through the harsh winter. I was very skeptical when I heard it and sure enough a few days ago they arrived in droves!
I finally broke down and got Sevin concentrate. I will just spray it on my raspberries and Honey Crisp apple trees though because I know it kills beneficials. (I will spray in the evening) I will just let them devour my hibiscus again this year because I don't want to use Sevin in my flower gardens.
I have two traps hanging and after just 2 days, they are both full. I am wondering if they indeed draw more beetles to the area than would otherwise come. I think I will just toss them.
