Summit Chemical Company Pond Mosquito Dunks - 2 Pack

I use these in my pool when we are not using it. It helps to keep the mosquitoes away and they don't breed in our pool

I have this in my Lily pond and there are fewer mosquitos. The water retention is great and effective. I like that I can buy a smaller size for my tiny pond.

No complaints this product its been working good

These work great to keep the mosquitoes out of my little porch ponds.

How in the world did I receive a completely sealed package with only one dunk in the two holes? While I've used this product before and found it effective, this seller apparently isn't doing quality checks at all.

So far so good, I'll definitely buy these again

Mosquitos leave. That's the whole idea

Why yes they work for that too! We live in the middle of a mosquito breeding ground; coupled with 3 pups that run in and out all day mosquitos are a big problem inside. They inevitably find the water in our commode. I thought I'd give this a try. I snapped 1 disk in half, used some ribbon (Don't judge, its all I had) and tied that around the 1/2 disk then dropped in the tank and left quite a few inches hanging down the back of the tank so the disk did not get caught up when the float moved up and down. In less than 24 hours, no more mosquitos and since then (3-ish weeks later) we have have seen zero return. Its been perfect.Update 53 days later: these are PERFECT for the toilet tank if you have issues with mosquitoes getting water from the toilet bowl. 1/2 of one lasted about 53 days. I knew it was time when there were small black, almost like dirt floating in the bowl. There was some residue around the inside of the tank, I rinsed that out and flushed a couple of times and then restrung another 1/2 if a disk and bit it back. We love these and couldn’t be happier!!
