I can only speak on the carpenter bee traps. We put out four this year (early April) when the carpenter bees came back. Last year we filled, treated and put fresh stain on wood soffits
after season in November. We put out traps this year hoping to deter more holes and more bee infestation. The traps didn't work. We swatted them with a tennis racket, put the dead ones
inside the bottle in hopes the phermone smell would attract other bees, it didn't. We took dead bees smash and wiped the four holes of each trap, still didn't work. Our last resort is to restain
the wood again now before any get inside the wood. We hope the smell of the new stain will
be a deterrent. At this point we have sprayed inside the old holes with Sevin Dust, put Seven
Dust in the wood filler when filling the old holes last year and coated over with a clear stain.
They are driving us crazy.
