I put a swarm into a TBH about a week ago. They have built comb on 5 bars. Unfortunately, they are building double combs and crossing over to the next bar! The queen is laying good and I don't want to rip out all their work, but I can't remove the bars one at a time to examine them without ripping the new combs. What to do?
I bet your bars are somewhere between 1 3/8" and 1 1/2". That's why I went to 1 1/4". What kind of comb guide do you have? It's worth having some frames around to tie errant combs into.
The bars are 1 3/8 inch and I use popsicle sticks rubbed with wax for starter strips.
