Video: Oxalic acid trickling
Here is a great little video that shows how to apply an oxalic acid trickle. It features Bee Craft Deputy Editor, Margaret Cowley (UK). She has the coolest little plastic squirt bottle that dispenses exactly 5 ml of the solution at a time. She just squeezes the bottle until the upper chamber is full, then she applies the measured amount into a seam of bees. After each seam, she refills the chamber and repeats.
The treatment is being applied on a December day with temperatures around 42-43 degrees F in a hive with one brood chamber and a super for winter. She treats the entire hive in a matter of moments—as fast as she can re-load the dispenser. Also of interest in this four-minute video is the cat and the woodpecker netting. (I love cats and never heard of woodpecker netting!)
Then too, Margaret cracks me up. As she trickles the solution, a little bee pops up between the frames and Margaret interrupts her narration to say, “hello.” So cute.
Be sure to enjoy.
