I've started using the Walter T. Kelley metal disk entrances on swarm traps. I'll tell y'all how I mount them and I'm looking for ideas on how others do it. I drill a 1/8" hole and drive an 8X32 screw, 1" long, from the inside of the box. It's hard to get started but once you do, you can drive it home with a drill. Then I push the disk on the outside, it's a tight fit, and drive it home with an 8X32 wing nut. To select the desired entrance just loosen the wing nut half a turn and turn the disk, then tight the wing nut. Any other ideas out there?
I"ve tried the plastic disks but they don't last in the sun and were hard to get for a while. I made my own for a while but that got old. These metal disks will outlast the boxes on which I install them and will probably end up in my will.
