Stop emptying your water trough daily!
This spring the mosquitos were terrible in the Midwest. I would have to completely empty out the horses 100 gallon water trough daily because there would be baby mosquitos swimming around in there. Threw 1/2 of one of these in the trough and BAM! no mosquito spawns! I replace it about every 2-3 weeks as it does start to break apart slightly. The horses don't seem to mind it floating around. I also use pieces to throw in puddles, bird baths, and basically any standing water around the farm.

Really Works

Lifesaver!
I have used these mosquito dunks for two summers now, I just ordered more in preparation for this year. Nasty mosquitoes like to plant their babies in my horses' stagnant water tanks and these dunks solve that problem flawlessly. When these float around in my water, not a single mosquito will touch my tanks. LOVE these. The horses don't mind them at all. They float around while the little pellets slowly fall off day by day and disintegrate until they are gone. One dunk lasts about 30 days. If you have mosquitoes, this is your solution!

I use these dunks Spring through Fall to minimize mosquito growth in the water troughs. I also think it helps keep my water troughs cleaner and thus healthier for my horses. They really do work!

Could this product be potentially dangerous for animals if it is in their troughs and buckets? It says for use in animal watering troughs, but then it says do not contaminate water or food supplies to dispose of product

BEST ANSWER: The Mosquito Dunks are non-toxic to animals and can be placed in animal watering troughs. It is advised to not apply directly to treated, finished drinking water or water receptacles if the water is intended for human consumption.
We change the water in our paddocks everyday... but would it make sense to put an extra bucket with water in it with these dunks to help control the paddock mosquito problem? Also, can they be put into the pond? It is safe to put into their drinking water???
TORRI D on Apr 27, 2016
BEST ANSWER: I used the dunks in a pond to prevent mosquitoes. The frogs thrived. It is supposed to be safe for mammals, although I have never put them in water troughs. I don't think your mosquito problem is coming from the water, especially if you change the water every day. I change my water either before or no later than when I see larva swimming in the water trough, about twice a week in the heat, and I don't have mosquito problems.
Your mosquitoes are coming from someplace else, I would expect. I would definitely put the dunks in the pond. I would think the mosquitoes would be breeding in the pond.

I don't know if the dunks would change the taste of the horses' water, either. I would not put the dunks in the horses' water.

My daughter who is grown up now, drank thuricide when she was 4 years old. My husband says the dunks
are made from the same active ingredient. We called poison control. They said not to worry about it. She would be fine. She was fine after drinking it.
Will this harm my chicken s or ducks?
Lisa L on Apr 4, 2017
BEST ANSWER: I use the Dunks in my stock tank where my mini horse and goat drink. Also it is where I get water for my chickens. I have not noticed that any of them appear to be sick from drinking the water. If you change your chicken and ducks water each day you shouldn't have problems with mosquito larva. Since I change my chicken's water daily I don't add any Dunks to the container for them. Hope this helps with your question.
Good for use in catch basins?
A shopper on Jun 24, 2016
BEST ANSWER: I would think it would be ok for a catch basin. We used them when we had large amounts of rain and the water stayed everywhere. Worked like a charm at killing the larvae
A large pond near our house supplies water to our horse, cows and garden, unfortunately it is a major breeding ground for mosquitoes. The animals don't drink from the pond directly but through water pumped from the pond to their troughs and the garden gets the pond water pumped through hoses & sprinklers. We do not drink this water ourselves but would this product or mosquito dunks be safe to use in it or would it contaminate our vegetable garden or harm our horse and/or cows?

BEST ANSWER: We use the dunks in the big water bucket at the back of the paddock (it is close to a canal) and my daughter's horse drinks fine. Just one note -- the dunks float at first, but after a month they start to decompose. It does not hurt the horse (ducks or cats that also drink from the same bucket) but it looks like pieces of dirt.
how much of an area will one dunk treat . ???
A shopper on Jun 22, 2017
BEST ANSWER: Effective treatment area is listed in the instructions. My usage is for large rain puddles on my property that don't drain. I used two dunks for an area about 100 square feet and the water is 3-5 inches deep. I highly recommend this product. Works well. The residue stays and works for the next rain shower or two. You can purchase it at any Feed Supply store, but it's a much better deal to buy at Stateline Tack. No harm to wildlife or any other insects. That was important to me.
Can they be used in a fidh tank?
Liz F on Jun 3, 2017
BEST ANSWER: I am presuming you mean an outside pond with fish. I have ponds but I have never used the "dunks" in them so not sure how they would work with fish. I do use them in my stock tanks that I water my horse and goat from and they seem ok.
Probably could contact the manufacturer and see what they tell you.
Good luck

Is it safe to be around dogs?
A shopper on Jun 27, 2016
BEST ANSWER: We use them in our horse water tank for our horses to drink out of, so I'd expect they'd be okay for dogs as well. The wild birds also drink from the water tank and they do fine and they're very sensitive. The description indicates okay for pets and wildlife and so far it's been okay for our horses.
