Answer: What you spray really depends upon what kinds of bugs you are finding. Aphids and pear slugs are common on cherry trees but some beetles dine on the leaves, as well. The control measures are different for each pest so the best thing to do is collect a few of the bugs, put them in a plastic baggie and take them to your local cooperative extension office or well staffed nursery for positive identification Once you know what the bugs are, you can choose the proper control measure. Best wishes with your cherry tree.
