jj, another member, cracker, used a garden hose and a bucket of soapy water on an ahb hive. like jack said, " a garden sprayer mixed with water and dish soap sprayed on them will do the trick." also, never tried this, but some beeks have used dry ice set on top the inner cover with a box over top and closed up. sulphur, i went digging around for some of tecumseh's post's on how this is used:
"just a pinch of sulfur incorporated into a 'hand rolled' cigarette which you can then place in a bit of copper pipe and then light and insert this into the front entry after lighting. you pretty much plug up everything else and hopefully trapping all adults inside. When I have done this I typically go in right at sunset when everyone is at home and by sunrise the dirty deed is done."
"make up a hand rolled cigarette, lace the tobacco with a bit of sulfur. I like to insert the 'cigarette' in a loose fitting metal sleeve or copper tube. stick one end of the tube in the hive entrace and plug the cracks. light the cigarette. the fumes are hydrogen sulfide, so don't be taken no puffs . very quick, very cheap and very effective."
"the product that kills the bees is called hydrogen sulfide, and you definitely will get lousy results and a headache if you attempt to put it in a smoker. it is the same by product of natural (food) decomposition that on occasions kills a navy man since it is heavier than air and accumulates at the bottom of the compartments where the food stuffs are stored. since It is heavier than air and disperses easy. the hive will need to be sealed fairly tightly. it can be 'applied' either at the top or bottom of the hive. the last time I applied hydrogen sulfide I did it via a hand rolled cigarette with a bit of sulfur added to the tobacco. if the hive is tightly sealed the results should be 100% after about a 30 minute wait."
if it were cold enough in florida, (which it probably isn't), take the lid off.
