Summit...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!

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.

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.

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.

This is a great product for controlling mosquitos. Be patient, it takes a few days for it to work.

They worked great in the past when I used them but something has changed. Was still eaten alive

I use them to keep the bugs at bay.

I buy these regularly to try to keep the mosquitoes at bay. I can break them up easily to put just a small amount into various outside containers and it works quite well at killing the larvae. It is odorless and easy to use. I appreciate being able to keep our mosquito population down without spending a lot of money.
