If you research it there are some strong beekeeping followers in Canada who swear by it.It could well be safe, who knows? As they do not say what is in it, let alone that it is safe to use for bees, it is not possible to say. One always has to bear in mind that generally, wood preservative prevents infestation by insects, if it works, by killing them.
If, as has been suggested elsewhere, it contains some mixture of disodium octoborate tetrahydrate / boron / boric acid then it is good for killing termites, powder post beetles and carpenter ants. It is an American product and I suspect may not be licensed for use in Europe (Disodium octaborate tetrahydrate). A European assessment of one of the main consituents merely states:

There was a paper published back in 1987 suggesting that the L50 dose (enough to kill 50% of the bees in the experiment) for boric acid was around 362 μg / bee (Atkins EL. Laboratory Bee Adult Toxicity Tests (BATDT) for boric acid, powdered, 100% technical. MRID 40269201. 1987.)
It would be interesting to see how you get on with it. Meanwhile, I may choose to stick with the natural protection afforded by (even UK grown) western red cedar.
I was only ever going to use it in pine if I went down that route but many on here have suggested the English Cedar is a better option. That is unless I get six numbers tomorrow then it’s WRC all the way
