    Default oxalic acid dribble

    Being the straight shooter I am, I would never consider using an unapproved compound in one of my hives. On the other hand, I have a friend who isn’t so proper. My friend applied an oxalic acid dribble to about 15 of his hives yesterday. Afterward he put clean corrugated sheets underneath those with screened bottoms. We stopped by that yard today and pulled sheets from beneath the hives that had screened bottoms. A half a dozen mites here…a few there and I….er… we were beginning to think the whole exercise was a waste until we got to this hive.

    Some of the hives had solid bottoms, so we weren’t able to look at those but nine had sbb and this was the only one with a big fallout but my-oh-my did they fall out.

    Mites will continue to fall for a couple of weeks.

    Ahhhh...you've had a friend who's done this too.
    PS...this was less than twenty four hours....makes me wonder why this hive dropped so many so quickly.

    From this which do you think is more effective? Dribble or sublimate OA?

    It's a shame the mites can't live in harmony with the bees instead they choose to over run them.

    Give the mites another 50 years they'll learn

    I really don't have an opinion. I've managed to get by with a single, late summer/early fall treatment using a thymol product. But then, last spring my mite loads exploded....and by the time I realized it, the flow was on and there wasn't anything to do. I ended up doing a post harvest, hopguard summer treatment that I didn't complete because of the heat.
    So this year I ....my friend decided to be proactive...in case this winter ends up as mild as last.
    And to answer your question....this is my friend's first experience using oxalic acid. He plans to apply it to his remaining hives over the next couple of weeks. Since his hives are broodless...or nearly so....the dribble method looked good.

    My friend likes to split a big double and flip the top box upside down and trickle down through the bottom bars and then between the top bars in the lower box. I'm sure he said he uses a 3.2% solution. Boy are his bees looking good right now. Darn if his name dosent escape me at the moment.

    How long did you use the thymol? I'm wondering if the mites developed a tolerance for it?

    Could you please give a little more detail on the dribble process.

    Here's a pretty good writeup on oxalic acid for varroa.

    I don't doubt that I have some. There's usually a small patch all winter. It is just as little as I'm likely to see.

    Oxalic acid dribble is hard on bees. It works only on phoretic mites. You can only do it once during winter or you may not have enough bees in the spring. Need to first dissolve OA in alcohol then add it to sugar water making sure your measurement are perfect then apply the right amount between each frame. If it's cold you could kill your bees with wet sugar water.

    I have oxalic acid vapor as a standby. You can use it at any temp. Any time of the year. It also only works on phoretic mites but you can use it once a week if you need to. It's quicker, don’t need to take hive apart. Just measure 2 grams per double and vaporize. The only down side is the vapor is bad for human and respirator should be used.

    I made a vaporizer out of copper pipe and no fittings, crushed the end and folded it over a few times. Took about 30 min make.

    The best thing is I did not need to use it this year.

    Unless you have 100's of colonies to treat gallons are not nessessary in fact any solution you mix has to be used or dumped. It doesn't keep for long. As for how much I measure with a triple beam scale in grams so no one is going to give you a recipe like one tablespoon to whatever. To apply you need a syringe. 5CC will work fine. A cc and a ml are the same. You apply 5 cc's or ml per seam for total of 50ml.for a double deep. You just need to count out 10 shots of 5. I do not break the doubles apart. This causes to much disruption at the time I do this which is Nov in michigan.
