The original folks who came during the first year were very careful to show me exactly what they were doing. They also came back a number of times to get rid of wasps. The new folks are fine also but do not really show me what they are doing. However I assume mice traps are baited since we don't have any mice. We didn't need them to do much inside this time since all the bug critters are still in winter mode. Everyone is very polite and well mannered.
