There is also an access point for mice in the rear bumper. Take a look at this:
https://www.youtube.com/watch?v=wUT1hErSwtg . To solve, you will need to take off the
mud flaps (held on with plastic clips), followed by the bumper (held on by ~4? screws/bolts
and at least 5-10 plastic clips). Note that not all plastic clips are the same size. Keep track
of where you are removing them from... Also, when attempting to remove the bumper, start
at the top of the wheel-well and start pulling the bumper up and out (directly away from the
side of the car). There is a stronger plastic piece under the bumper. It DOES NOT come
out with the bumper. If you pull too hard, you will damage the plastic holding the bumper to
that piece, or that piece to the rest of the vehicle. Instead, attempt to look in between the
bumper and the panel above it. You will be able to see some clips there. Using a screw
driver, you can depress the clips that slot into the holes in the bumper and carefully
remove the bumper. Note which parts the bumper is on top of/under/inside. You may want
to walk around the bumper and take a video, especially from the underside of the bumper,
to ensure you put it back on right. Once the bumper is safely removed, you will see the
vents from which mice may be entering (1 on each side, identical). The next step is to
remove that vent, place some thin, strong metal mesh on it, and put everything back
together. You may wish to place some foam pieces on the metal mesh to prevent it from
contacting another component and vibrating, creating noise.
