Mouse Hole?

I have a 2018 double cab and I’ve only had it to the mountains a couple times and both times I end up with a mouse inside the cab and/or headliner. Any ideas where the critters are getting in? It’s stock with no mods to create any holes.

 

Under the wiper cowl, you will need to pop off the wiper arms and there's where you will than need to grab some gutter guard from Home Depot/Lowes and cut to fit over the holes...I used silicone caulking and gorilla tape on top of that to seal it off...I haven't had mice infiltration since. It's also a good idea to activate your recirc button in dash to close off acces to them or at least make them work harder to get in. Check your cabin filter in the glove box and start there...each side of truck under wiper cowl presents a wide open hole that needs caged up...

 

This has been a problem for awhile, not even sure they fixed this for the new gen. Here's a good link to figure out what to do.

Just wait until they chew on your washer fluid hose and wiring.

Seems like every winter I’m replacing hosing.

 

I keep those square rat trap baits on the plastic engine cover in hopes they will go for that over anything else. I learned they melt a bit though so I put duct tape in the grooves so its easy to clean up when I want to put a new one.
