mike, I tried using a friends today on my palletized hives and I cant fit the vaporizer in with the core-plastic insert that I used to cover the screen bottom on the pallet>the same for screen bottom boards? mine are on screened bottom pallets! '
Make an insert you can slide in the door to block the bottom.
It's fast if you have two, I sit the battery between, start one, then start the other while the first cools. While the second cools, move to the next set. I use a small car battery with a handle. Never needed more battery. I do like to have a wet rag or water bucket available to really cool them off. The only time i've ever made the bees mad is sticking a hot unit into a hive and hitting a cluster of bees.borrowed a friends today to try and I got to tell u that if u are doing over 25 hives you are gonea need a larger battery and another vaporizer if u are going to make time.
