Wear red clothes when working outside if u can. Bees and wasps/hornets can't see red. They love white or yellow!. Also grow mint or any kind of mint in your garden or border around the house. They repel all kinds of wasps and also mice. Wasp do not like the smell of cucumbers either. Remember a wasp can only sting once. They leave the sting inside you. Bees can keep stinging repeatedly. Don't wear a lot of cologne, perfume or aftershave. They LOVE it and think you are a flower to pollinate. Always work early mornings as bees and wasp don't move to much until mid afternoon when the heat and humidity is higher. Also baby powder is another smell wasps do not like. They are repelled by the talc in the powder. They are SO beneficial in the garden and try not to kill them if possible. I know sometimes it can't be helped.
