Japanese Beetles started hatching a few weeks ago and will be around until September. They are extremely heavy in middle to South Naperville, Aurora, Batavia, Geneva and St. Charles at the moment.
They love a variety of trees and shrubs but their favorite is the Linden followed by White Birch, River Birch, Elm, Purple Plum and certain varieties of Maple and Crab. They also attack certain shrubs too numerous to list. If you see these trees displaying a ‘brownish hue’ toward the tops of the trees (as they like to feed in the sun) then you have Japanese Beetles.
You can also look for lacy leaves laying in the yard under the tree. The photo shows five beetles feeding on a Linden leaf creating that ‘lacy’ appearance.
We normally perform two spray applications to limit Japanese Beetle damage. Pictured below is a photo of a Linden tree which was taken last year in Naperville. This is the kind of total defoliation and damage Japanese Beetles are capable of if a tree is left untreated.
