I have had success with trapping HOSP when they “take over” a box to roost in for the wintertime. Excellent time to use the Van-Ert inbox trap – not an easy job in the wintertime because have to monitor closely, but worth it when you can rid them, even if it is one at a time. Although, many here then use them as decoys in a ground trap. I believe it would be too cold at this time of year for a decoy to survive very long, though.
