I have some nice old brood frames from a dead out that have very little nector but still have pollen in them.
If I put these frames into some swarm traps, will the pollen get robbed out ?
I'm in Wisconsin so we don't have high numbers of SHB, but will have wax moths.
Don't know how to get these frames clean other than putting them out and let them get robbed if they will rob pollen. ..
Pics may not show pollen all that well, but I'll try.
