Max,
Bee careful with this product. It bought it in 2012. I did a test run with one of my empty hives. After just one day I had a big hole in the screen top board and the screen bottom board.
If this was 2012 that you had this experience, Jim, then that wasn't FormicPro, it was Mite Away Quicks Strips. MAQS was the precursor to FormicPro and had a different formulation. I used MAQS the last year it was available around here, before it was replaced by FormicPro, which I think happened in like 2020, and MAQS was much less nice of a product. Also it now says on the FormicPro instructions not to use screened covers during a treatment, although screened bottom boards are fine as long as the entrance is fully open and the insert is in. I have mostly screened bottom boards, and I've never had any trouble with it.
How many hives do you have?
I have 10 hives.
Does the product come as a bulk pack ( looking for savings )
I think I have seen bulk purchasing available on their website or from big bee suppliers. I don't know what the deal with shipping to Australia would be, but I'm sure you could find out. The company that makes it is called NOD Apiary Products, here is their website.
