So the first year the mosquitoes were fewer, we still had most of the dragonflies from all the larvae that had overwintered. The second year we had hardly any dragonflies, and the few mosquitoes we started with were back around. It's impossible to eliminate every source of mosquitoes, but by eliminating the biggest source- the pond - we took away the primary food supply of the dragonflies.
It took two years to get the dragonflies back. The first year the mosquitoes were pretty bad, but the second year the dragonflies had returned, the mosquitoes are back down to just a few, and balance is restored. So yes, the Dunks work as advertised. And no, they didn't poison anything else - the fish, frogs, birds, skunks, deer, racoon and cats all seemed unaffected. But - when you interrupt the natural food chain in an ecosystem, there are consequences.
These would be great if you have standing water that's just enough for mosquitoes but not enough for the dragonflies. But if you enjoy your dragonflies and recognize that they do a pretty awesome job at hunting mosquitoes, you may want to think twice before taking away their food source.
