Re: My Hopguard experience
The mineral oil fogging thing hit my country in a big way around 2 years ago when heaps of people rushed off and bought one, thinking a great way to solve their varroa issues. Nearly all those foggers are sitting in sheds / up for sale now, just wasn't that effective. To kill a few mites, it will work. To actually eradicate mites from the hive, it has to be done every three days for several weeks, not particularly good for the bees.
44 years, been commercial, outfits up to 4000 hives, now 120 hives and 200 nucs as a hobby, selling bees. T (mostly).
