Summit Chemical Co. Mosquito Dunks Set of 20

I collect water in large trash cans and these work well at preventing mosquitos. I also have a large trashcan filled with tadpoles (baby tree frogs) and these are safe for them.

Cheaper than other brands but work just as good. Have been using for months with noticeable results in mosquito reduction.

I like how the dunks work in standing water and not being harmful to animals.

We used these in the little stream that was beside our home and in our pond. It greatly reduced the mosquito population this year. Nothing really eradicates the pesky creatures. TIP: You can crush these up and distribute in your yard/grass. Mosquitos love moist places and we think it really worked in our backyard area, which held moisture.

Goodbye Mosquitos.

This product is well known for mosquito control but how happy was I when I discovered a dual use?! So I have some potted plants, some are outdoor and others are indoor that I set outside on occasion for natural sunlight (my windows do not get direct sun). These darned flies started infesting my plants, flying everywhere, with the occasional up the nose. I tried neem oil (also from trying on mosquitoes with zero effect), the sticky things, watering less, and mulch. none of it has worked. One day, I’m bucket watering, you know setting pots in a bucket of water as a gnat prevention (instead of watering from the top where the gnats live) and in goes a dunk for mosquitoes. Before I knew what was going on, no more gnats! So, now I grab a dunk, mash it up and it goes in the watering can. Also take some of the grinds and sprinkle liberally in the plant pots - right on top. Stuff is amazing!

I think it works really cannot tell if it works or not, I can't count mosquitoes

Excellent results from product but very hard to open package.

I am a great fan of these dunk's. they work well and as long as you remember to drop one in every 3 weeks or so (rather than once a month as recommended) they will keep your pond free from the dreaded mozzie plague on a permenant basis. These Dunks seem thinner than the 8 pack but seem to work just as well and are considerably cheaper per dunk.
