It has been an unusually warms fall/winter and now that all the flowers have died off I have been getting tons of bumble bees in my feeder. I know they flock the the food because of the dust but I am wondering if anyone else is having this issue and if anyone has any solutions. In the spring we usually have a good enough amount of flowers bloom early enough for the bees to not swarm the food but how do I manage this in the winter when nothing is blooming?
