Formic Pro is a great treatment with high efficacy - it kills mites under the brood cap, where they reproduce. Comes in handy ready to use strips, is made with all-natural ingredients and is also biodegradable.
Not only is this a quick treatment (7 days), there is also no need to remove the strips from your hive immediately. After the treatment period, used strips become inert so you can leave them in the hive until your next inspection and then simply compost.
