New beek here. I got two strong hives from a friend and I have two nucs that I've had for a couple of weeks. The weaker of my established hives appears to be quite aggressive recently(first couple of months were fine), so I plan to re-queen in a little while. There is some brood still, but from what I've read, re-queening might be the answer. However, while checking honey supers on the other colony, I dropped a super and really made those bees angry. I got one sting and they really got on me. I quickly put it back together and retreated into the woods to shake off the followers. I went into the house, showered, washed my stuff and dried it. I went back out to the hive and I used cool smoke to the front of the hive and waited a few, then I cracked the top super and smoked a bit. When I lifted up the top super, those bees came rushing out like they were going to kill me and about 8 bees immediately started stinging my gloves. Again, I closed up the hive and retreated to the woods. So, my question is, how long after really pissing off the bees should I wait to go back in? A day, a week? Clearly, we have learned that two hours isn't enough time. I've been in there plenty, the weather conditions were okay, maybe slightly breezy, I've never had them come after me like that though, let alone twice. What am I doing wrong here?
