No! Unlike honey bees that live in large hives, solitary bees do not aggressively guard where they live and will only sting if handled. In fact, Ryan - one of the founders of Scopa - is deathly allergic to bees, but doesn't have any concern about being around these bee homes! (He's the one that does most of the video footage we have on Instagram with up-close shots of them.) That being said, be safe and don't try to catch them!
