Just received notice today that in a few weeks by county road commission will be spraying an herbicide in my area - Tordon 22K. Is anyone familiar with this product and has any suggestions about whether or not to confine bees on days when they are actively spraying? And if so, what method have folks used to confine their bees in the past? I can imagine it getting really warm inside the hive on a hot summer day if the bees can't get out and aren't able to ventilate properly. Thanks.
