Japanese beetles are popping up in gardens a little bit early this year, according to agriculture.com.
The site is reporting that farmers in Illinois and Iowa have laready seen the pest, which usually arrives in mid-June. The Black cutworm and European corn borer have also been spotted, as have soybean aphid nymphs.
Besides the traditional insecticides and hormone traps (which may actually make the problem worse), milky spore bacteria can be used to exterminate the beetles and their larvae.
