Sorry to hear you lost your girls this winter. Between mites n yellow jackets I at a 50% colony loss over here in Western Washington State.
I really don’t think your going to enjoy the mix on that tooth pick … bees like it but not really my taste or choice. Now as for tossing your valuable resourse (those full drawn out comb) don’t do it or toss them over here to me in Puget Sound region.
I’m going to post some pretty icky looking frame that are safe n reuseable. We have very damp conditions here in the greater Seattle n Cascade Mtn area n yes the pollen mixed that’s left in a die-out can look very nasty.
That stuff in your tooth pick sure doesn’t look
anything like European or American fowl brood to me (but there are smells n test for both some written in the inner searches of this Forum.
I don’t see wax moth issues either n a frame can get very nasty … and those you need to freeze for several days to kill off any live larva or eggs.
Let me add several photos for you to see n others to comment on … I love being the devils advocate n see what happens when I toss ideas n pix’s out …
It’s totally amazing how my bees can cleanup n rework comb n frames of nasty wax. My wax isn’t old enough to cut out n render to beeswax blocks yet.
