Hey. Are these the same as the carpenter bees here in GA? Ours look like bumble bees and are actually a type of fly. They get by on their looks! Anyway, I have about 30 holes in my new pergola and I'd love to find a way to divert their digging.
I have Mason Bees. I thought I lost them the second year. The following year or three years later I found them nesting by choice in my hiding places in cedar shakes. Apparently they liked the wood home over the tubes provided by the seller.
I gave up keeping honey bees with all of their present problems and concerns.
I have one, I believe it's the same one that comes back every year. When I couldn't kill it, because of fear, I looked it up and found out it's a solitary bee that does not attack and does not bore their own holes. So that was cool and I named her Lucille. She gets confused when I move a hanging plant but finds her wood beam with-in the minute. Sometimes she stops in front of my face to check me out. But goes about her business as soon as she sees I'm not a threat. Or maybe she's trying to tell me something. I'm definately building the 4x4.
