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!
