Hello, I'm 50 years old. Live in Oxford Connecticut and I always had an interest in honeybees, but never took the responsibility of having my own.What changed that was seeing Silence Of The Bees. This made me decide to give beekeeping a try,so I purchased two 3lbs packages and installed them on 4/19/08.Everything has gone well up till now, been having some problems with defensive bees trying to work it out. This forum is fantastic. To all I say Hello and Thank You.
Welcome to Beemaster!!
As colonies grow in size they generally do become more defensive as there is more to defend and protect.
As spring gives way to summer, then fall, and there isn't as much nectar available the bees don't quite have as much to do, and seem to be more aggressive.
I believe this is your case, but if for some reason next spring your bees are much more aggressive than you like, you could requeen them with queens that have been bred that exhibit gentle tendancies.
Good luck to you, we are here for you.
