Summit Chemical Company Pond Mosquito Dunks - 2 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!

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.

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

ممتاز

Half of the packaging is missing. I hope the product is not complete dried out. I thought it was very weird.

We have a small water feature in our garden, so for the second year I am adding one of these periodically. They certainly do seem to keep the mosquito population under control. My only quibble would be the claim that one lasts for “30 days or more.” They absorb water and presently begin to break apart. Perhaps the active ingredient remains in the water even after that? Don’t really know, so once the dunk is entirely reduced to just floating debris, I scoop that out and add another. That means the six-piece card doesn’t equal a six-month supply. Possibly this is just my misunderstanding, however.

Perfecto lo recomiendo para matar los mosquitos tigre . Lo uso en hidroponia . Los mata en un día , no queda ni una larva . La única pega que se deshace el corcho muy pronto

Perfecto para lo que toca. Lo utilice en un estanque de riego, donde había muchas larvas ya que el agua no se recambia demasiado. Ya no quedan larvas, el producto cumple las expectativas, una amarilla tiene un buen tamaño y alcanza para un mes. Muy contento con la compra.
