I use FormicPro sometimes, and it is very easy to use and organic. The biggest benefit is that it is the only treatment (that I am aware of anyway) that kills mites under the brood cappings. It also will kill sick bees, so I always use it if a have a hive that is acting sick along with having a high mite count. Plus, it's safe for supers (although I personally still don't treat with supers on, since I'm worried about the smell of it being transferred to the honey). The downside is it's very temperature sensitive and will release too quickly if the temps are too hot, potentially leading to queen supersedure, excessive brood mortality, and absconding. I only use it at the lower end of the recommended temperature range, and I've never had any of these problems. That price is about the same as over here, actually it's a little bit cheaper for you guys (and yes, I did remember to convert AUD to USD

). It's a very efficacious product, so I've never treated a hive more than once a year with it.
