Ive had bees for more than 20 years.
#1. The calmer YOU are the calmer THEY are. So....If you need a space suit from NASA to work the bees, by all means get one. For most everyone else, light colored clothing and a net to keep bees out of your face is good enough. (angry bees tend to go for dark spots and CO2 like your breath...you are breaking into their house...wouldnt YOU be angry???))
#2. Gloves are OK, but you are cumbersome with them. If they make you comfortable, by all means wear them!!!!!
#3. A Smoker is an absolutley MUST HAVE ITEM!!! The smoke "calms" the bees as in it makes them go for the honey....a full bee is a happy bee.
#4. slow deliberate movements keep bees calm.
#5. as soon as you open the hive you will have a 6 foot circle of swirling NOT SO HAPPY BEES flying around. Dont stand in front of the hive, they dont like that!
#6. Your bees will either bee calm or nasty....If they are nasty close it up and try another day. Bees get moody too.......BUT if they are AGGRESSIVE all the time then you have another issue.......THere is a GREAT difference between a defensive hive and in aggressive hive. Defensive bees will be all over you but leave you alone if you move 20 or 30 feet away. Aggressive hives will follow you for a half mile or more.
I just LOVE sitting next to a healthy happy hive...smelling the smell and listening to the busy buzz of the whole thing. LOVE IT!!!
