I just wanted to say thanks again for your website and information. I found it last year when combating carpenter bees on our kid’s playset. I did everything you suggested and put the NBS30 additive on the playset when I restained it. We have NO BEES this year and all the neighborhood kids have been back and playing on it like crazy!!!
I actually came back to find the link to more NBS30 as one of our neighbors asked what we used. =D
Thanks again for all your help!
