The pan vaporizer generally run ~15A at 12V = ~200watts with initial cold htr inrush of ~20A. But the lawn mower battery should handle it. I have used modified Harbor Freight chargers on the switch...

The unit I made has the "snout" coming out ~1/2" from the top edge at a 45deg, running down the side of the cup and bend at a 90deg to go in to the hive. The main cup is surround by a 2nd copper...

Oxalic Acid Vaporizer for honey bee mite treatment. 3 prong grounded 115vac supply, copper cup (cucu) with 250Watt 52761527655276352767(2Amp)(380W available for $20 additional), and temperature...

I am assuming that you are trying to run a ~2"x2"x1/2" 12vdc "pan" heater. The ones that finish the vaporizing in ~3min draw ~15Amps at 12vdc for the 3min. With is in mind, maybe a lawn tractor...

I believe that moisture is a problem if it condenses on the inner cover, rains back down on them and then gets cold and freeze on the outside of ball. Thsi will conduct the heat away from the inner...

Didn't mention that I have 3/4” hole in most of my supers just to left of handholds for upper entrance in winter and summer. The front insulation, in winter, has a ~3 x3” hole to allow bees in and...

I run heaters under my screened bottom boards on each hive. Use PID temp with thermocouple (tc) on the 100 watt heater with temp set price at 90F Have reduced entrances and at top let intercover...

Been using oxalic acid for as long as approved in USA and maybe awhile before. I have used Formica acid too. Nasty to handle. Use the WVU method and make up my own pads. Back to OA. have bought pans...

Interesting, I have handled 10 fr and 8fr deeps, medium (Ill size) and shallow for comb honey for 50yrs. As I got older and weaker the deeps got too heavy and the mixture of sizes got to be a pain. ...

I use the harbor freight charger no 60653. Cost about $30 on sale. They have to be “modified” to work without a battery connected and selected to the Em Start position. The nice thing about using a...

I have commented on the PID controller. Several types are available. The C100 is generally the least expensive $6 to 15. There are 2 output types available, relay for max amperes & SSR ~5vdc. The...

As to items on the market, they are expensive if many hives (2 or more?) are to be monitored. My son and I have a way to monitor the temperature on 48 hive and more if required 24/7 every 1min and...

Pictures of my 120v vaporizer

I like the new 120vac band heater method of Oxalic Acid . The speed that it can be applied; and the minimizing of "upsetting" of the bees during application are the pluses. The cost and the need for...

Parkersburg, WV for past 55 years born in Pa about 50mi south of Penn State and 60mi west of Harrisburg. My dad got bees in 1952 as payment for a funeral. He was and untertaker.

Have been around honey bees since 1952. I am running up to 48 hives. Want to follow the treatment of mites, small hive beetles, and other items such as heating hives in the winter, monitor heat in...
