I need some help. I am looking at the Demise Dust 1lb vs the PT-230 Tri Die 8z. I have 2 nests of carpenter bees in my soffits and I don’t know which product I should purchase. I will need to treat again next year. But I was not sure which product I should use. your advise would be appreciated.
I think the PT-230 will handle your needs fine. A good rule to follow here is that the PT-230 can usually treat at least 5 nests. One can never tell for sure unless you are certain you know just how deep each nest is in the wood. The depth is what dictates how much material will be needed; nests which are 2 feet or longer will require a lot more drione compared to a nest which is only 6-12 inches deep.
Based on the limited information you provided, I believe the PT-230 will suffice and handle your problem for now most definitely. If you only have 1-2 holes to treat next year, it should be more than enough for you at that time as well. But if you end up finding 5 or more holes, get the 1 lb DEMISE, along with a good HAND DUSTER, to insure good coverage and proper product distribution.
