In the hives that I have treated with Menthol on the bottom board (daily temps are 80+), the
bees are staying on the outside, rather than going in.  Will this affect treatment?  and will
brood rearing be affected?"
 
Yes, menthol is alien to the beeses, and they will carry it out if it is not in a mesh bag.
 
However, it is normal for them to sit on the front porch, (and up the front wall,) when it's hot
outside.  It allows them to ventilate the place better, (which they probably want to do about
now...)
