, other than that, I did have a night earlier in the year when I smelled pesticides on the air. If it is that, about all I can do is change out frames come Spring if they make it through the Winter I think.
Along those lines, are some strains of bees more tolerant to the common pesticides then others?
Too bad they aren't more like cockroaches. I seem to have some of those that are resistant to anything short of a sledge hammer.
Although this isn't a heavy agricultural pesticide use area, there are still too many people that have an aversion to "eewww bugs!!".
