LIke everyone, I have put the boat away for the winter. It's kept inside a shop with the covers on. The other night I had a Nightmare That a rat got in the boat and, you can figure the rest. My question is, what could I put in the boat to deter them from looking to make a home in it?

A snake

Then the wife won't get in it ??????? Hmmmmm Then the wife won't get in it. Hmmmmmmmmm That will work

I have always used dryer sheets every where
just make sure the area is dry where you place them

also helps take away the smell in hte spring time

I used moth-balls/moth crystals in various places in the cabin, cockpit, and engine compartment. I made sure to get some down in the stringer area in the engine compartment so they wouldn't have a party underneath. It worked well.

What smell?

From the Rat pizz of course!

I have put those little boxes of rat/mice poison in key locations inside the cabin and cockpit. Figured if they got in there, they would do too much damage before they croaked.

i use the dryer sheets to. seems to work. also use them in the summer and i dont get any boat spiders.

Never use poison, traps only..if you poison them they will crawl somewhere and die, leaving no trail to find them but a smell that will absolutely drive you insane. With a trap all you do is pick the sucker off and reset for another.
