My neighbor just purchased a vibrating pollinator machine, like an electric toothbrush, that comes with plastic spoon and stick, retail $50 — but on sale! It’s great for massaging his shoulder, we discovered. I’d rather just avoid killing pollinators with pesticides and encourage pollinators. I bought a mason bee house. How do I attract mason bees? We grow vegetables and flowers (mainly dahlias). We put the mason bee house in a clump of evergreens.
