Found a mouse nest! GRRR!

IMO, seal the trailer to keep them out in the first place. I went all over our trailer and sealed every spot where a pipe or wire went through the floor. Some of these can be hard to get at - requiring removing false panels, and crawling around underneath it, and my trailer had one underneath the tub that proved tricky. I did that four years ago and haven't had a single mouse in the trailer since. (They still nest in the wheels, spare tire, and bumper. That last one proved interesting one year when I went to use the sewer hose...)

I used expanding foam (Great Stuff) and it's worked great.

I was trying to be sensitive to anyone who hates the thought of killing an animal/rodent. Gloves will take a mouse off a sticky trap.

The key to sticky traps is to put one bit of dog food in the center of the trap, but you have to check the trap so the mouse can be either dispatched or released (your choice) without suffering.

I am not aware of any "sticky trap" that you can release a mouse from. The ones I know of are a shallow, rectangular tray filled with goo that is incredibly sticky - once a mouse gets caught in that, no way can it be released. The recommended "dispatch" method is drowning the mouse, tray and all, in a 5 gallon bucket full of water.

I prefer the traditional snap traps. I use your basic American cheese - break off a small square and squish it onto the trigger. After a short while it will harden (you may want to actually let it harden before setting out the trap) and when the mice have to chew on it the trigger gets tripped.

As to baiting, I found the "Ramik" and "One Bite" bait bars to be much more effective than "De-Con". As another poster mentioned, but the bait outside of the camper if possible. If there is a concern about other animals (especially pets) getting to the bait, you can buy bait containers that will prevent anything larger than a mouse or rat from accessing the bait.

I use Irish Spring soap and Bounce original scent sheets in our trailer... I don't know if they are keeping the mice out, but the trailer smells great in the Spring!

For Mice,We have had good luck with Irish Spring soap. I read about it on the fiver forum. Open box and placed around any where they might enter. Under the sinks, water line entry's etc. It has worked for us any way.

Wear a mask when messing with those droppings

I could see on this trailer all sorts of openings they could get in. I was able to see all the lines that run under the floor are not sealed, water, drain, gas. Big holes with no foam sealing. I looked down through the floor where the Aux gas line comes in and could see light. I saw a place where the bottom trim of the trailer would allow a rodent could get under the trailer to the drain lines and into the camper. I feel that at least they didn't have to chew their way in, they had an "open door". Also nothing seems to be damaged other than the rugs. I have set a trap an haven't caught anything...yet. Glad the sofa and beds are untouched!

Might have the opposite effect. I think rodents are pretty opportunistic. I had 2 gerbils in college. One died and the other...well...I think you probably get the picture. Sorry.

I've found that decon UNDER the RV works best. Keep it in a ”mouse accessible” container and they dine there and don't even bother coming in...been working so far. Get them before they even get in.

With that amount of droppings you are going to need more then one trap. Better look for the nest and check all your systems before you head out. A friend of mine just found a big mouse nest in his furnace this year.

I just went through my spring ritual. Every year they fill the cooling fins on the Kohler powered mower that I keep in a shed at the MIL's. Full of soybean husk. At least this year he didn't eat the insulation on the spark plug wire. Now if someone finds something that does keep them away, I'll be making a trip to the store after verification.

Path1, I like your thinking, super glued peanuts. I may have just found a new use for Gorilla Glue. I wonder if a half a dozen traps laying around all winter, each with a deceased relative would be a deterrent for the rest of the family.
