Infrared game cam...
I bought a motion detected game cam and set it up where I thought the entrance was. It accomplished two things...
1. It showed photos that confirmed their entry point
2. It established a pretty reliable pattern of the hours they used their "door". Around 10pm, 1am and 3am.
They also establish a latrine for the entire colony to use. Look for brown streaks on your walls or ceilings. Their nest will be near there.
.22 bird shot should not hurt your siding. Try a test somewhere.
