As riders and online shoppers, we know it can be tough to buy a new bridle or pair of boots without trying them on. That's why we moved the fitting room to your living room (or barn)! From breeches to blankets, if you or your horse can try it on, you can return it, free! Just use the pre-paid return label included in your order within 60 days from the purchase date. And of course, please make sure the item is in like-new condition with original packaging (we said 'fitting room', not 'war room'!).

Why We Love This

Dunks, along with B.t.i. Briquets, are the only sustained-release B.t.i. mosquito larvicides available. Safe to be used in drinking water.

Mosquito Dunks is rated 4.3076923076923075 out of 5 by 13.
Rated 5 out of 5 by from They do work I placed half of one dunk in my 100 gallon stock tank and it does work as advertised. I have the luxury of keeping the outer edge of my tank outside of my fence, so was able to tie the dunk to a string and attach it to a stake - keeps it out of reach of the horse, but then I can easily retrieve it and remove it if l feel it doesn't need to be in there or while cleaning, etc.

Rated 3 out of 5 by from They are ok I'm a bit disappointed. I bought 2 packs, thinking I would use them all summer & share a couple. The amount to put in is based on bucket/tank size so I had to break them in halves & quarters. This would be great for large stock tanks and ponds. And, they float. That's not good when the animals think its something to eat. So I sunk a few in empty butter containers with holes in the lid - even though I don't know if they only work if they are on the surface. They are holding up & I do see some particles floating in the water. No mosquitos :)

Rated 4 out of 5 by from Works well The disks float and can be broken into smaller sections for smaller water sources. Some horses may play with it if bored.
