I bought some bt from sundance (thanks sundance). I saw a moth in some old comb. So far no damage to anything but I should really get the bt applied. So my question...is there a period of time after an application that it should avoid contact with bees? My bees may be coming in the next week. I feel like I would rather be safe than sorry now that things are warming, but don't want to apply it if it will have some effect on bees so soon after application. I suspect it's ok for bees no matter how long after application but again better to be safe than sorry.
