Thread: Closing holes in boat storage

How big are the holes you are talking about? If they are "quite large", one option for you with the electric will be to use a combination of PVC pipe and electrical grommet. Let me see if I can verbally describe what I'm talking about. First, you'll need some electrical grommets. They are rubber plugs with a hole in the middle and a cut from one side to the hole. Next, you'll need some PVC pipe with an inside diameter the size of the outside of the rubber grommet. Cut the pipe as long as the thickness of the intended spray-foam "wall" and cut a slit down one side of the pipe so that you can fit the pipe sleeve over the wiring.

Now, just fit a pipe sleeve over the wires and insert a grommet to seal that up. Slide that assembly down to where you want to spray foam and build your "wall" around that. You now have a sealed wall with a permanent channel to run wires.

...or you could "Smooth Out" a gob of RTV Silicone on each side, with or without the aforementioned grommet that could all be removed if needed later on down the road...
The grommet could be home made, piece of flat material, hole in the middle, small slit from middle to the edge, you get the idea...

Rats will eat thru anything plastic or soft enough to sink a tooth into. Setting and checking some nearby traps will give you an indicator as to what’s around. I use to get some mice in my boat during the winter in TN and they liked to unravel the edge of the carpet to make their nest. If I was to plug a hole, I would cut a grommet as previously stated but it would be aluminum and silicone into place. Part of your best defense is to not call it done til spring and check on it every couple of weeks to see that nothing is developing. And they like peanut butter in the traps.

Go to a big box home improvement store and buy a lot of fine steel wool. Stuff it in all the holes. The rodents will not even try to chew it.

I put dryer sheets all over my boat in the garage and keep poison out as well. I arrange the poison in a certain way to know if there has been any activity. If I have a problem I would use steel wool as well.

thanks for the response the steel wool is what i think i will use. the foam will get in the carpet.

You will never seal it tightly enough to keep rats out. If they are there and want in, they’ll find a way.

The secret is to kill them all, and take away anything inside that might attract a passing rat to come inside. If you have one, you have dozens. Traps, poisons and cats will take care of them.

I finally got rid of my mice in my workshop. I get little green cubes from the COOP. They seem to change brands every so often, but they work. I used to use glue traps, but mostly caught black snakes. I had to pour used cooking oil on them to release the snake.
