check with major bee equipment suppliers,, they make bee escapes that can be bought and used, but these take up to 24 hrs to be effective.
I have seen people use a leaf blower to blow the bees off the frames.
I use a FUME board and Fishers Beequick sprayed on it, it works in about 10 minutes on a sunny day.
whatever way you choose to get the bees off the frames,, think about how you are going to keep the bees off the supers and frames until you can get them inside.
I take one outer cover, turn it upside down in the back of my truck. then use the beequick spray on the fume board. after about 10 min,, I check to see if the bees have been driven down, if so, I take the super off, put it on the upside down cover, and then immediately cover it with a regular cover. then go to the next super.
IF you have only a few frames that are ready, , you could have an empty super and put in on the upside down cover, put the frames in it, cover them,, and after you extract, put the frames back in the super,, the bees will clean them up and repair comb damage,,
let me know if you need more info
