I second the last post. When I feed I don't, quick peeks don't. I hived 20 packages and no smoke and that was a disaster. Don't think the smoke would have helped. SW would have though.I put no. But that's not completely accurate. I use smoke very sparingly. If I go into a hive and they are bouncing off my veil and get that angry sound, then if I HAVE to be in that hive I will start the smoker. 95% of the time I can do what I want to do with out smoking. I did a split the other day, 2 hives involved and no smoke. I also don't bother them much anymore. Not like I used to when I first got started. Oh I'd be in there once a week, looking for the queen, Just to be sure. Now I see the queen more often than not and i'm not even looking for her.
