I am perhaps the most vocal in the school "No Coumophos U" and have been taken to task by many over my statement of "I will watch my bees die before I use coumophos!". I suppose I should clarify that statement a bit, and no, I am not backing down. I WILL watch my bees die before I use coumophos. I never cared for the chemical merry-go-around as Andy called it, but I am on that merry-go-around; TM treatments spring and fall (dust, no patties), fumidil-B (2 gallons medicated syrup 2:1 in the fall if I can get my bees to take that much and 1 gallon medicated syrup 1:1 in the spring) and currently Apistan(R), spring and fall. I'm simply drawing the line at coumophos. There are a lot of alternatives to combat mites before resorting to coumophos. IPM is the hot topic in the industry these days. Drone trapping, queen confinement, screened bottom boards, oils of essence (which I have not yet tried), and at long last the gel formulation of formic acid will be available next season! I suspect there may be some mite relief associated with shook swarming too by breaking the brood cycle, although reinfestation will be a problem. Only after I have exhausted all the alternative methods will I be forced to watch my bees succumb to the enemy. A strategy currently being promoted is the possibility that you want some hives succumbing to mites anyway - culls out the weak bees and propagates less-than-super mites.
