I know Delta Dust is the thing to use then plug hole, but I had someone come and treat my porch and they used a wet spray that dried to a powder that was called "Tri-Die". I read the label on the can for what it kills and it never listed carpenter bees (or any bees for that matter).... Although they were dropping left and right... Is it safe to say that "Tri-Die" will also work in killing these carpenter bees?
Tri-Die contains the active ingredients Pyrethrins and Silica Gel. This combination of active ingredients offers a pretty fast knockdown and residual control of lots of insects, even those the product is not labeled for.
