One thing I’ve learned over the past few years of chasing swarms is to never get tunnel vision on a swarm call. Especially during prime swarm season. Always walk around and look up into the trees and at nearby buildings for a beeline. If you find one, you’ve very likely found the source of your swarm. Then, keep looking around for other swarms that the caller did not see. Below is a video of what started out as a call to remove a single swarm. Then, plans changed. Also, always have more than one swarm box setup in your vehicle. I never leave home without at least 5.
