Killed around 40-50 yellow jackets the last week there. All were in the bedrooms. My girlfriend was actually stung on the foot after accidentally stepping on a yellow jacket. We also found mouse droppings in the kitchen the day we moved in and we inevitably saw the mouse a couple weeks later. Ended up having to live with a mouse defecating on our stove tops for much of the summer and the help that she offered was pepper mint spray and 3 mouse traps (one of which was broken). The mouse was never caught.
