Wasps and most insects are repelled by Demon WP. They do not like it and most of the time won't come near it. It also kills them when they contact it. For best results, spray the exterior of the building - around eaves, doors, windows and other areas where wasps could enter. Spraying inside the building will not prevent them from getting inside.
