Last year one of our neighbors had gypsy moths in their oak tree. They contacted the City of Lakewood. And they came and spayed the tree. The owners believe that the City of Lakewood sprayed too late because as of today, my whole street is infested with gypsy moth caterpillars. One reason for my concern is that the gypsy moths can kill a tree in just 2 years. They can take all the leaves off of your trees before you know it. And then when they are done with your trees they will go for your bushes. My two front oak tree are infested. I have photographed the caterpillars for you to examine your trees. The caterpillars live in the ground all day and come out at night and climb up your tree and eat your leaves. On a cloudy day like this morning they will on the tree trunks and even on the side walk. Look for leaves that been chewed on under your tree. Look for little brown dots on your sidewalk that you usually see in the fall not the summer (see my photo blog). We believe that this is the Caterpillar feces.
