Practise with it in the open air a few times. Time how long it takes to fully vaporize the OA with your particular setup.
While I understand I dont want to take a big whiff of it , is the general consencus that it is a fairly safe and "organic" method of treatment a fair statement ?
I had to make up a jumper cable from a 25' extension cord. It's fairly small gauge wire, maybe 16ga. With a small car battery, it takes 3 min. I let it cool down in the hive for a minute, then pull it out and dip it in a jar of water to really cool it off. Then I wipe it out and move to the next. Most object to having something shoved in their front door, others not so much. I've watched through an observation window in a TBH and they don't seem to react much at all.
Certified Naturally Grown.
I went back and edited my post to add that.
edited to add that while I've never bothered to go for certification, I do try to apply their standards.
But do not mess with the dribble method; use the vaporizer. Read Part 2 for the vapor method:
I got my oxalic acid (wood bleach) at Ace Hardware..... Seemed to be the only hardware store in my area that carried it....
Probably a dumb question, but are you supposed to remove the supers before you OA vaporize?
I don't know what other people are doing, but I treat with OA after I remove supers in the fall and then again early in the spring.
If I use OA it is after I have removed the harvestable honey for the season. The OA I use is 100% OA. Vaporizing is the only method used on the colonies that look like they need it in the late summer/early fall.
I got one for 90.00 had to put clips and a cord 10.00 works great just did my 2nd treatment very easy.
Yeah, the Heilyser is 90.
I am glad to hear OA vaporizing can be done with sbb.
Does the acidic vapour corrode the screen?....break down the white plastic?
How do you insert the vapourizer? Seems a really stupid question but with my sbb when I poke something into the entrance it hits a board about 1" in.
If I can get it to work with sbb then I will order a vapourizer post haste.
You need a 3/4 in. entrance and just slip it in.
do you treat while they still have brood in the hive?
why vaporize it ?
This is what I ave gleaned from folks in the know...I am not.
OA kills phorectic mites on adults...not in the brood. It doesn't harm brood but if you treat when there is brood you need to treat a few times to get the emerging brood with mites.
Formic acid..MAQS....use once...7 day treatment...gets mites both on adults and in brood...but is greater chance of bee loss, especially newly emergent bees and ones soon to be dead anyway.
So use OA in late fall when no brood, or use repeat Q 7-14 days.
Hope I have it correct.
