Hi there a pretty quick one, I have used a ispm HT treat wood as entrance reducer…Is it going to be armful for the bees?
Thanks in advance for you tips…
HT is a non-chemical heat treatment. Not harmful for bees and not an armful either…

Two is better than one entrance!!
Also notice the yellow strip in top of the entrance…is it pollen??
I can’t zoom in close enough to see what you are talking about, but I doubt that it is pollen…
