Mosquito Dunks

You have to keep after it but if you use this as directed it works very well.

these really work. I had an empty container left in my bake yard it rained and fill with water. I noticed that there was mosquito larvae swimming in the water. I broke of a piece of this dunker crumbled it up a little and sprinkled in the water. checked it the next day and they all where dead. I could see the wormy looking larvae at the bottom. I use this in my pool to help prevent mosquito larvae. I put in a Caroline dispenser and just let it desolve

These seem to work good. I have notices a decrease in new born mosquitoes. So I guess overall it does help with control

They work great for my backyard water keeps mosquitoes away

Bingo! Exactly what I was looking for. Outdoor hot tub w/o heat in natural setting a/k/a no electricity. On a hot Florida day, all you want is to float on a raft with an umbrella drink.A large hot tub size and easy in/easy out. I moved it to a back section with concrete pad. Mosquitoes zeroed in within 2 days. Now I can basically keep it chemical free and use the water drained on grass or shrubs. Far less expensive to change water than add electric, chemicals. By the way, the Mosquito Dunks don't kill tree frogs, birds, or animals.No mosquito larvae; no mosquitoes.

I don’t know that these work to keep the mosquitoes from laying there eggs

These worked so well for us last year, that we bought them again this year. We can spend time on our porch without being bothered by the mosquitoes. We'll definitely buy them again.

I used in a small water feature by our front porch. Did a great job of stopping mosquito production. Lasted 30 days. Worked as expected.Wasn’t as good for the bird bath as it fell apart faster - maybe picked at by squirrels?
