Plus it's between 85 & 90 degrees F so it's too hot for formic acid.

This is correct, the upper temperature limit for formic pro is 80. A bit lower is better.

With a small hive (nuc) you only use 1 strip of apivar.

I have had mixed luck with all of the mite treatments I have tried. Some years apivar seems to work, and others it has not. I have had problems with formic with a well ventalated hive (quilt box) or when it was very large, but it has worked fine when I close the top and use the 2 pad method with large (5 box) hives. OAV works most of the time, but it is more work. OAV with a wand also does not seem to get to the top of large (5 frame) hives as well.[/QUOTE]
