Installed package on May 30TH.I have been feeding 1-1 SS with HBH,I did not treat the new package with Fumagilin-B at install.My question is should I go ahead and treat them now or wait untill fall.The package is 7 weeks in since I installed them in a 8 frame med. and foundation.Two weeks ago I added the 2nd. med. with foundation but swapped out 2 frames of brood from the bottom with 2 foundation from the new med. on top.
