Although still around, the Winter Moth issue on Cape Cod has seen a significant decline and is only a problem in isolated areas.
However, the damage from Cankerworm caterpillars is now more noticeable. Their activity causes significant defoliation of a variety of deciduous landscape and forest trees.
Cankerworms typically hatch at the end of April and into May and begin feeding by chewing many small holes on the newly forming leaves of the trees. Most damage occurs about the time the leaves become fully developed and trees can be completely stripped of foliage.
If you begin seeing any black dots resembling pepper on your cars, deck furniture or deck, you most likely have cankerworm caterpillar activity and should schedule a spray.
