Well, wasps can bite and bees can sting, can't they? Enough reason to not welcome them to my garden I think. To be honest I have never been sting by a bee but.... I hate when one disturbs my peace of mind while I am sunbathing because I think/fear it could sting me. I don't even like flies nor mosquitoes even if those won't bite me.
Wasps are dangerous and need to die by fire, but bees don't want to sting you as it is their last defense and then they die from using the stinger. Don't bother them and you can walk right through them. I had one queen Bee sting me when i was young but I sat on it! Damn that hurt.

If where you live supports bats then put up some bat houses and that will take care of the mosquito's. And making sure there is no standing water on your property keeps the mosquitoes and flys away as well.
