Responsible Solutions 110-12 Mosquito Dunks, 6 Piece - 2 Pack

I have a Koi pond and was afraid to use these at first, but the mosquitoes were so thick. I tried it anyway, these work so well it cut down on the mosquitoes in my yard by at least 70% very happy with the purchase. Update; before using these, I would lift up the flat rock underneath my waterfall to clean algae in. There would be 1 million mosquito larva, so I put some of these dunks under that rock in three later there were only a few larva, I’d say the product works extremely well! I highly recommend.

Works great for Mosquitoes

Anyone who owns a greenhouse knows the biggest battle you will have are the flies/gnats/whiteflies, etc. We still have to use the sticky yellow fly catchers, but putting these dunks in a few containers around the greenhouse has been amazing. After two years, I can say we have the flies under control. Not that there aren't any, but there are hardly any. You might see one a day. I'm okay with that also because I have some carnivores out there.

Buy these every year. Perfect for keeping ponds and water features free of mosquito s without harming plants or birds.

Kill the nasty mescito

I hope to eradicate the mosquito population near my camp this spring.

I'm hooked! I have several rain buckets and small pools for plants and outside pets and these dunks are life savers.

Seems to work as advertised.
