responsible solutions 110-12 Mosquito Dunks, 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!

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.

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.

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.

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!

These are a must in an area withstanding water. Great value for your money. I personally have not sensed an oder. It is very effective and can help with maintenance with a regular routine.

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.

I was looking for a safe and effective way to deal with mosquitoes, and these dunks are exactly what I needed. Effectiveness: These mosquito dunks are highly effective. I placed them in my pond and rain barrels, and within a few days, I noticed a significant reduction in the number of mosquito larvae. They really work to break the mosquito life cycle. Functionality: They are incredibly easy to use. You simply drop a dunk into any standing water source. I found them perfect for a variety of water features around my yard. The dunk dissolves slowly and releases the active ingredient over a long period. Natural Ingredients: One of the best features is that they use a natural, biological larvicide. I was concerned about using harsh chemicals, so knowing this product is safe for my fish, pets, and other wildlife gives me great peace of mind. The 6-pack is a good value and provides enough dunks to treat several areas.
