I've been feeding birds cracked corn all winter but as the temperatures get above 40 the corn is covered with honey bees gathering or eating the corn dust. They are very enthusiastic and leave covered with it, but don't seem to be filling their pollen sacks with it. I have a couple hives that look very good this spring but I'm concerned about any insecticide problems from the corn. I spoke with the farmer who told me he does plant non-GMO treated seed (neonics?) that have a lowest level treatment available and he does spray a minimum amount during the summer. Does anyone have any knowledge or experience with bees consuming corn dust? What are they getting? Any known effect on the hive, brood, etc.?
