Message: <blockquote data-quote="John B" data-source="post: 13500" data-attributes="member: 207">I have been wanting to do some experiments with oxalic fogging for a while so I deliberately left some lives at home under treated. I may have got a bit carried away with the under treatment as when I finally got around to making my testing gear three of the four was showing signs of PMS. I had intended to monitor the natural drop for a couple of weeks but they would have died if I had left them (they still may). Two hives were weak to start with and are only two frames of bees but had a natural Average drop over three days All of 26 and 7 followed by 170 and 105 the day after the first treatment and the two that were one box of bees were 1 and 50 followed by 27 and 310 . All hives still have brood. Frankly I'm amazed that three of them are still alive. It's my fault I just got busy with other projects. At least I now know for sure that six random fogs over the autumn is not sufficient. The only good thing to come out of it so far is that the hives with the least mites is the one I used for breeding in the autumn.I intend this to be an ongoing project and I may have to bring home some new hives in the spring. The main thing I'm trying to find out is how many days do the mites keep dying after a fog . There is too much conflicting information out there and like Alistair says it can be very difficult to treat to a regular program. I have seen suggestions for everything from only immediate knockdown to 5 or six days with the highest mortality being on the fourth day.Please note some of those higher numbers might be out by the odd Mite or two.</blockquote>
