Mice - Any advice on where to look for points of entry?

Just got a text from my wife, who says she's found evidence of mice in drawers in the TT. We have an enclosed underbelly that has been parked in our paved driveway - and everything has been closed up since our last trip in August. I won't be able to get home to look until later, but I'm having trouble imagining where the entry point might be.

Any suggestions on where to look for points of entry?

Also, any suggestions on how to make absolutely sure that we eliminate any mice that are there?

    Even a new battery couldn't save this one ...

  • Has your TT been plugged into AC? On my previous TT mice would just walk up the electrical cord and into the mouse hole especially made for them by the manufacturer. I made the modification with the Marinco type plug and no more mice in our TT. That mouse hole we pulled our electrical cord out of was just under the couch. Direct entry from outside. That is why they put rat shields on ships when they tie up in port. Mice and rats crawl up the mooring lines.

    OK - some people are just smart-aleks and can't help themselves!!!!:D
  • Mice can come in through the tiniest of holes. What I do (did this in my home), is put steel wool in some of the small crevices. Haven't had to use this the RV and hopefully won't!

    Now I also have a mini-schnauzer who is excellent at ferreting these little vermin out, and he will get them and then once they stop moving it's no more fun for him....not only is he man's/woman's best friend, but he's a champ in my book!!!

    Hope this helps

    Mice aren't the most significant issue (although they are a concern). The real issue is the snakes that could follow! If DW ever finds a snake in the trailer it will be the last time it is ever used!
  • Ant place hoses, wiring, gas lines, etc enter the trailer from the under side. The enclose under belly is not likely to keep mice out. We had them come in ours where the intake for the water pump comes up from the tank. Wad up some window screen around the pipe and cover/fill with expanding foam. Mice can chew through the foam, but the screen stops them.
  • I would wait until it's dark outside. Turn on the lights inside TT, put a lantern in storage bins and close doors. Any place that you see light escaping can be a route for insects/rodents. Also, make sure the furnace vents are covered, (make sure to uncover before using again).
    I plug the holes with copper/steel wool that I've placed inside a plastic bag. The steel can make a rust stain if not in a bag. The mice can't chew thru metal.
    Make sure to clean TT. No food,( even canned), soap, candles, firewood, etc. I don't use traps or poison, as they either have an attractant or require bait, which just attracts more mice.
    I also use those electronic, sonic things. That requires the TT to have power.
    I park over a concrete pad, avoid long grass/weeds/overhead trees, etc.
    I don't bother with moth balls or dryer sheets.
    I put rubber snakes under the trailer to give the mice a little scare.
    The biggest things are to plug entrances, and remove any thing that will attract them-as mentioned above.
  • Look anywhere anything runs through the underbelly skin. Low point drains, wiring are the most common items that will do this. You can use expanding foam in moderation to sure these areas up.
