I just started out with four hives. They are located in my hayfield a few hundred feet from my apple orchard. The orchardist has informed me he sprayed his orchard nearby today, and will be spraying mine tomorrow, and said I should confine the bees in their hives for three days. I took beekeeping class last year and was told having bees near an orchard would not be a problem, just confine them during a spray and after it has dried they could be let loose. I have the hives outfitted with robber screens that can be closed off to confine the bees. Last night I shut them in. Other than a few who showed up today and are buzzing about, the mass are inside the screen. I took off the sliding board off the bottom screen last night thinking it would help them moderate hive temperature. Any advice on how to proceed? For at least this apple year this will be an issue.
