It is too bad they can be such a nuisance, because they really aid in managing other pests. On to the point, a few factors that can help when dealing with them. Light-colored clothing is a good choice. Beesuits are white because of thermal reasons and white is not a recognized typical 'threat' color. All the animals that would harass them are darker colored. And, as others have mentioned, colder weather is a good time to deal with them. They can still sting, but they need to group up to generate heat and are clumsy and slow without it.
