insulation works - see the result.

That's a good question Vance.  I assume you mean a good hive wrap for wood hives?  I don't know, I hadn't thought about that.  It might.  The stuff I saw was at a local lumber chain here in Michigan called Self Serve Lumber.  I haven't noticed it for sale at the national big box stores, but then again I haven't looked real closely.  I believe the price was about $50 for a 100' roll.

I figure I could protect about 42 of my jumbo sized foam brood bodies with a roll of the stuff so the cost would be about $1.20 per box to wrap/protect.  So far that is cheaper than the alternatives I've stumbled across if I can get it to stick to foam and if I can get paint to stick to it.  These two things I do not know.

Now THAT will be interesting to see!  Close off that bottom vent, give them a little top venting, and let's see what you find!
