Re: Mason Bees & Wasps
I am just getting my feet wet with mason bees. Isnt there a point where you can open the tubes and remove the cocoons? That would let you know real quick. Also, how large of a tube are you using. I think 5/16" is supposed to keep most wasps out. Again, just starting out. Way more questions than answers.
I moved this thread to the Alternative Pollinators forum. You may get a better response to your question here.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
