Hello, First time mason bee host here. They seem to be doing quite well so far in Nanaimo and a couple tubes have already filled up. I do however have many unwanted flies in my yard, and am thinking of getting a couple of those non-toxic scented fly traps where you add water. My question, if anyone can help, is will these traps attract the mason bees, or any other bees for that matter? I am looking to target the flies but do not wish to harm anything else. Thank you Dave
