Homemade oxalic acid vaporizer for mite treatment

Homemade oxalic acid vaporizer for mite treatment from the back of beehive. The bees are much calmer when treatment is from the rear of the hive. Check the hive condition before treatment. High mite population can cause the bees to abscond. You don’t want to treat an empty hive.
Don't over treat!
Use black iron, copper or stainless steel for the pipe and cap (or the entire device); do not use galvanized steel.
Use propane, the lower heat will create a longer evaporation and less toxic gas.
Don't over heat, gradual heat is better.
Preheat the outside of pipe to prevent condensation before heating the cap.
Thank you for all your comments and suggestions. Let’s take the bit out of mites!

    Good job, thank you for showing your method of construction. I know that we are using these outside, but inhaling zinc is not a good thing - much safer to use black iron instead of galvanized pipe.

    Or you can thread the pipe cap for a large Ford Diesel engine glow plug and apply 12 volts from a fully charged Semi Truck battery. It will shoot the vapor better than the professional models. While the regulated dose of Oxalic Acid is in fact 1 gram…. The University of Florida has done years of testing in which observations were made indicating that this is not a substantial enough dose. Their observations are that 4 grams provide a lethal enough dose (to veroa mites) of Oxalic Acid to be effective against 70% of veroa mites in a large 2-4 frame hive

    I like the idea of being able to build something myself, that doesn't cost an arm and a leg. I've seen a couple of comments somewhere else saying the vapor isn't as effective if above a certain temperature. Using a propane torch as the heat source, it seems it would be easy for me to be over the optimum temperature and not even know it... Do I have a valid concern? Thanks!

    I love making things cheaper than you can buy in the shops or online. This is wonderful and it works but he cost of the initial plumbing fittings and ongoing use of the propane are dearer than a factory made one from Amazon at less than £20. That seems the way now, cheaper to buy stuff ready made than save some money and make it yourself ☹️ They are taking the fun out of everything ☹️☹️😭

I know that the probate 110 is costly but this is definitely not a good alternative. The idea overall I understand is a good idea but it’s not practical enough

    If you have ten hives, just make ten of these. These look cheap to make. When you treat just leave the thing in the hive and move on to the next hive and treat. Do this right down the line. If you have more than ten in one location, Im confident the first one is cooled down by then.
