What type of snake is this

Seeing cracks on the walls or ceiling is fairly obvious, but the common hidden gaps that let insects in are usually hidden from sight. They are usually around light fixture electrical boxes and under moldings around windows or exterior doors.

The best way to stop these unwanted pests is to remove device covers and light canopies and caulk around the electrical boxes. A thin carefully applied bead of painter's (latex) caulk (do not use silicone caulk because it can't be painted) can seal up gaps around window and door moldings.

Not only will you close up places for bugs to get in, but you will help stop outside air from entering the room, thus lowering with your heating and AC costs.

Wear a thick glove, the gardening kind is preferred. Flip a Ziplock or similar plastic bag inside out and cover your glove with it. Firmly grab the mouse (and its associated trap) with your gloved, "plasticked" hand and with your free hand, roll the Ziplock back out so you can seal it completely, with the mouse trapped inside.

Lay it on the floor, preferably a driveway or garage. Whack the poor thing with a heavy magazine or a shoe; make sure you hit its head for near-instantaneous death. It has already suffered enough; this will help it pass on quicker.

After you do this, please make sure you remove all the glue traps your pest control folks installed.
