Food debris will be a major attraction to some of these insects, especially in autumn. If an insect lands on you or your food, do not become alarmed. They are only investigating or foraging. Blow or gently brush the insect away. DO NOT swat or wave at the insect.
Slow movement is best.
Do not destroy them unnecessarily. They will not sting without cause. If you are allergic to a particular stinging insect, carry an epinephrine kit with you or have immediate access to one.
