:evil: I have been told that the best lessons learned are the hard ones.I learned first hand about mice. I had a hive that was weaker and struggling going into winter.I did not put any kind of mice guard on the hives. When I did my fisrt inspection last week the weak hive was dead and had some unwelcome guest in it. They did not get out of that hive. I could not believe the damage though. They completly eat up six out of ten frames. I would like to know any ideas that would work to keep out the mice that is cheap but effective.
I also had a stronger hive that a mice tried to get into but I found it dead under the hive top.

I use hardware cloth, a roll is cheap. Cut to 4" X width of hive entrance or better make two at 3/4 entrance width and overlap. That way you can get a tighter fit without messing about for an exact cut fit with each hive. Fold lengthwise and staple in place. I'm not sure of the exact size, perhaps 3/8" hardware cloth.
1/4 inch hardware cloth is the cheapest and easiest to come by, all I use this year was entrance reducers with the 1 inch opening and had no problems but my hives are from 12"-22" inches off the ground also.
This is the best you can go. Metal mouse guards which also make great entrance reducers. Considering the cost of a hive, this is small potatoes cost wise.

You could try the above plans for an open mesh floor design, which has an 3/8" wide 'underfloor entrance'. So no need for mouse guards at all.

Andrew this underfloor entrance is great, I am swiching to it this year. You can see them the video in http://www.beemaster.com/beebbs/viewforum.php?f=45. I wondered whot were those big front openings for . Now I know.
I was looking but did not see,Is there a way to close it up during the winter to conserve heat in the hive?
