Re: bee hive in the wall of my house
Welcome Steve, I have visited Nevada city many times. Beautiful town. We used to camp just outside Nevada City every year at Diamond Arrow.
It woudl almost be worth the trip to check out your colony of whatever they are just to visit the town again.
Yes bees can get testy when food runs short, they loose there queen or they are otherwise being harassed on a regular basis. My bees got pissy for the first time yesterday and I really don't know why. the only thing I can think of is the heat. Maybe a bit of robbing going on so they where a little more on guard and jumping at anything that moved. This would not be good for the passer by.
