MOSKILA Mice Cube 4 Pk - Reusable Humane Mouse Trap

does it come with the bait?

Used to use these and they worked everytime. Years later now with new cubes and this mouse is getting out after eating bait. How?

Are there air holes? I want the mouse to be able to breathe.

Is there a way to add additional ventilation holes without a drill? My drill is broken, and I like these, but want to make sure I can ventilate it.
