Fresh Cab scent pouches- how many do I need?

[63air]

In the past I used moth balls for rodent proofing but I don't like the odor so I have decided to use the Fresh Cab product this year. All the implement dealers in our area carry them and the farmers really swear by the product when it comes to protecting their equipment. I was able to get them at the local Airstream dealer ( Adventure RV ).

Will 4 pouches be enough for my 19" Globtrotter and will they last until spring.

Information from the company web site:

You worked very hard to afford your recreational vehicles, protect your investment with the rodent offending qualities of Fresh Cab. If you have ever had to repair a chewed steering wheel, seat cushion, rewire electrical or clean up the filth of mice droppings you will appreciate the simple prevention Fresh Cab offers.
The advantages can be applied to campers, trailers, boats, jet skis, snowmobiles, summer cabins, classic car interiors and any other small enclosed place where mice dwell!
Just add 4 pouches in the enclosed area and the odor will discourage mice from calling it home! Each box containing 4 pouches will last one season (about 3 months).
