Re: Hop Guard
I like hopguard for use on nucs, swarms, and weak colonies. I have found that it gives a good kill on exposed mites, it's main problem is the strips dry out by the 3rd day. If I were doing a single treatment on strong field colonies I would use another product, such as the thymol or formic acid treatments. For hobby beekeepers with only 1 or 2 colonies it is not all that bad a product. I don't mind spending .75 or .80 cents on a colony to knock back the mite population and slow their growth for a month or two.
It is like a lot of other items used by beekeepers, one man's meat is another man's poison.
