    • Try them! Huge reduction in mosquitoes when used regularly!
Size: 6-Pack
Nothing harmful, except for to the blood-suckers! Help tremendously! I have a reminder set to add one to the ornamental pond monthly. (Based on size / gallons, as to how much to use.). No harm to the "fancy goldfish" in the pond, no harm to birds, nor dogs who drink from pond. But - yes - prevents mosquito breeding. Our winters aren't cold enough, long enough, to rid us of mosquitoes. Yet other chemicals harm humans and other life. Yes, I'm a hypocrite. Love life, but ... mosquitoes? Grrrr. BTW, if there is anywhere that standing water can't be avoided, you can easily break off bits of these for those areas, too. They last! Work for at least a month, when used as directed. WELL worth this cost! Follow their instructions or ask. here, and someone will reply! ... show more

    • We use these each month in all of out water features
Size: 6-Pack
We use these each month in all of out water features. We have much less mosquitoes when we use them than when we dont use them. Seem to be working and will continue for the foreseeable future.

    • Effective and Easy to Use
Size: 6-Pack
I bought these for my waterfall trough. Sometime I dont run the waterfall for a few days. This helps keep mosquitos from breeding in the trough. Easy to use.

    • Highly recommend
Size: 6-Pack
Has a midge issue in our turtle tank...these dunks are amazing! Only used 1/4 of a dunk for a 75 gallon tank. Not only did the midge problem disappear but the water in the tank is clear and the turtles are happy and healthy!

    • Mosquito dunks

I am not crazy about these. they tend to clump up and look gross. I will buy the granuals from now on. These just clog up when wet.

    • Effective & Harmless to wildlife!
Size: 6-Pack
These are ideal for our small, in ground, fountain. (2ft x 3 ft x 18” deep) break them into thirds and drop one into the water from time to time, removing worry of mosquito larvae, without concern it could harm wildlife.
