I'm approaching my 5th winter with bees. The first two autumns ('08 & '09) I fed thymolated syrup to the few hives that I had and I did a few sugar dustings.

No thymol was used after October '09

I may have done some sugar dusting in 2010 but I'm not certain. I believe I would have, but I overlooked doing them. Comb suspected to contain thymol syrup have been culled out.

2011: No treatments... went into winter with eight colonies and seven made it to spring.

I don't practice any drone management for mites.

Would my colonies be considered treatment free at this point?
