greg, i use fisher's bee quick and fume boards. if you have a queen excluder on, take that off. i saturate the fume boards, it says criss cross i think. i give it more.
i set it on and hit the top (metal) with a propane torch and heat it up.........i wait for a bit and peek in to see if every one was chased out, and if need be, hit the top again with the torch. the supers are carried to the truck, stacked and covered with plywood tops that fit the boxes so bees can't get back in, anything will work to cover them. there will always be stray bees in the frames, i might repeat the process on the truck, from the top of the stack, usually not necessary or with 2 or 3 of us taking supers off, someone is checking and brushing them off the frames if i was impatient on chasing them out of there. this works really slick for me, i have a number of fume boards, and i just go down the hives, put them on, heat each fume board, it's pretty efficient. go back to the first one, take the super off, replace the fume board, hit with the torch, go to the next hive, repeat the process.
it sure beats using honey robber or bee go.......like to gas yourself with that stuff.....
