[ You are not allowed to view attachments ]80 count on 24h varroa drop count after 2g (1/4 teaspoon) OA vaporized using my DIY vaporizer on a 2 mediums langstroth hive.
:say a 12-16oz can with one end and contents removed, church key or pocket knife, wide mouth Mason jar lid, two 1/4" x
2-1/2" dowels, stilt 2-3/4" tall by 1", beeswax tea light candle, doses of OA.
Punch 2 holes in can with church key, see attached for locations, place 1/4" spacers inside of mason jar lid (i hot glued my kits), see attached for locations, those spacers provide a gap for an oxygen intake, place stilt 2-3/4" tall by 1" in center of mason
jar lid (hot glue), see attached, place tea light candle on stilt. Apply OA dose to top of can, light candle, place can on top of candle, cover hive and seal.
One may use an empty Super for the shim allowing placement of vaporizer unit in the hive.
Note 315 degrees to vaporize so flame tip needs to be within 1/4" of can's surface with that spacers, penny etc, may be necessary to tweak for proper heat at burner as candle burns down.
