Hello Mike & All, Mike wrote: Do you know if they did two packets one after another or only one packet? All the beekeepers I have talked to only used one packet and all but one used the repackaged packets. I have pointed out on Bee-L and at meetings that Bob Stevens of BetterBee listed two treatments for better varroa control in his catalog. All beekeepers reported excellent Tracheal mite control with the *Apicure*. I believe the *Apicure * might have worked better if two treatments had been used but in my opinion the infestations levels of varroa were to high from fluvalinate resistant mites for ANY treatment to work. None of the beekeepers I talked to did any testing before, during or after treatments. Several used BOTH Apistan and Apicure. Two tried Coumaphos after they saw their treatments were not working but most the hives died any way. Using Apistan this year might work in your area but if you use apistan you need to test with rolls or sticky boards (like you would with IPM controls) to make sure your controls are working. I personally disagree with much of the published data on the amount of infestation before treatment should be done and still save the hive. The best research I have found is still some of the oldest information. The research done by Dr. Marion Ellis of Nebraska has proven the best information on testing I have come across. Hope I have helped. My back hurts like Ulee Jackson in * Ulees Gold*. Only up on the net for short periods now when I come in taking a break. Good luck with the bees in the coming season!
