Motor oil / diesel stain on my barn and they are gone. I use the traps as well. I try to stain once a year and they don’t like that.
Yes, at one point I used to pay my son $.25 for every carpenter bee he swatted.I have a trap (they really work!) and tennis racquet. I wear them bees out!
But you know what? I still have as many as I ever had. Maybe I'll see fewer for a day so but then I get reminded that nature is vacuum...it's a losing battle .
