I know a lot of people use nucs for catching swarms, but many swarms are too large for a nuc so they don't get caught. If it was me, I'd use a deep box for the swarm trap. Most swams like to land 6 to 10 to 15 feet up in a tree, so if you have the ability to hang a box that high up, that's what I'd do. Check on it once every couple of weeks or a month is fine. If you get one, then remove the box and place it in your beeyard at dusk.
Live life with gusto, having no regrets, being thankful every day, and cherish each moment as it happens.
