jen, it is not about the foundation, or any foundation. bees will strip the wax from any foundation, and from beeswax foundation right to and around the wire, when there is little or no flow on, or when you have given them too much foundation to draw without feeding them 1:1 syrup. the best time to give them foundation and get them to draw it out, irregardless of the type of foundation is in the spring. feeding them 1:1 syrup will help them draw it out, so they are stripping it to use elsewhere. if you are feeding them and they are still stripping it, my guess is too much foundation all at once to draw. don't feed them winter patties. just keep 1:1 syrup on until all of the foundation is drawn.
