I was quite tardy about putting on the mouse guard, figuring that with my hive entrance nearly two feet off the ground it was no big deal. When I checked the sticky board today there were two "turds" on there. They were black and a bit smaller than a rice grain. Did not really look like mouse poop, but possibly could be. So my question is: is there anything else that could account for that. With a mouse I would expect lots of droppings and they normally look bigger. If it turns out to be a mouse, should I open the hive and get it out, or do something along the lines of poison?
