Several friends have sent me the URL to Howards trial of a product called Mouse Free that he is testing . It is sprayed onto the underside of the RV. It should be interesting to read about his evaluation after a month of having the fiver parked on a ranch lot while he and Linda are gone.
It did not look very easy to apply. He also mentioned that he had sealed any entry cracks and holes he could find with steel wool. So if he has no mice when they come back he really won't know if it was his steel wool work or the Mouse Free. (if he had wanted to do a real test he would not have put the steel wool in, but his main concern is to discourage the mice from getting in any way he can!)
I wonder how long it would be effective and how often you would need to reapply it.
So I've done some reading on The Mouse Free web site and found their warranty. "The product is guaranteed only if applied by an authorized dealer" (estimated cost is $10 per foot which would come to $360 for our rig.) And it must be reapplied by a dealer within 12 months to keep the warranty in effect.
There are a number of exclusions in the warranty and can be read here. Including not applicable if you park within 48" of an overhanging tree or leave a door open. (for how long?)
You can apply it yourself, for what looks like about $130 plus shipping. That's for one gallon and a sprayer. They also have a free shipping and free sprayer deal with two gallons for $199.
For now I'm going to stay on a very vigorous bait and trap program.
At this point the RV is very clean.
No food is in it, and there is no water.
I am not dealing with a BIG infestation. Only a few droppings were spotted, and one mouse was quickly caught.
Yesterday I added six traps in the RV and bays, and bait under it.
I also put three blocks of bait, each on a white paper in two of the largest bays.
This morning I checked them, and the three blocks in the bays were GONE! The traps were undisturbed. I got down and checked the blocks I had put on plastic lids and slid under the rig. From what I could see, none of them looked disturbed.
I replaced the three in the bays and anchored them with string. We shall see if they are disturbed tonight. Sometimes it takes a second feeding.
The good thing is it rained last night, for the first time in months, and the information on the bait package said that after eating it, the rodents will seek water.
The only water is outside. I hope that is where they will go to die!
We shall see.
So thanks for the advice.
For my followers who are not into RVs this may all seem a bit disgusting. Mice are not talked about in "polite" society, but they are a fact of life in the RV world.
