Carpenter bees are normally present in the spring and possibly again in the early fall, depending on what region you are in. It would be a good idea to consult the cooperative extension office in your area for more information on the best time to apply in your specific area. You may also want to look over our Carpenter Bee Control Guide if you have not already done so.
