I have two swarm traps out, both "baited" with Swarm Commander. I've been re-spraying every 7 days +/-. Question: if the swarm trap is actively being checked out by scouts when I go to check on them and re-spray, should I re-apply the Swarm Commander or wait and come back another time?

Opinion only. Spraying IN the trap is too strong. Once a month on the outside would be enough. NO to your question. Once they are checking it out, the smell is no longer needed.
