Usually, wasps build their nests under roof overhangs and eaves, and some of them end up getting inside and dying. Despite our efforts to keep up, they are often quicker than us. Typically, there is a can of wasp spray available, and maintenance can also handle wasps. On the other hand, carpenter bees - which are large, noisy, and black - pose no threat to humans because they lack stingers. However, they do cause damage to wood by creating holes in it. Fortunately, they seldom make their way inside the cabin.
