Kills mosquito larva
Living in the woods with lots of damp leaves and places for water to accumulate is a mosquito birthing ground. I'm a bug magnet. The two don't go well together. These are a must for my small pond (even though it has has small fountain - moving water is supposed to discourage mosquitos & three wonderful frogs!) and the bird water feeders. We have a large covered water barrel for catching rain water from the gutters, but the top is recessed enough for water to lie there after a heavy rain. It is located right below where the outdoor water facet is located and every time I have to turn on the hose I'm horrified by all the larva swimming in that small amount of water. I broke off a 1 inch piece of this dunk and the next day checked & nothing was moving in that water! Now I place a small piece in anything that tends to collect water! Anything that can help discourage the production of mosquitos & works has my vote. This product does work! They have increased in price, but some things are worth the money.

It works like it said it should.
This stuff actually works. I know it was wrong for me to allow so many mosquitoes to grow in my water cooler for so long before buying this, but I had to get that bum out of my yard, like I said on my youtube video. Farro Wife But soon as he stop sleeping in my yard, because he could not take the mosquito infestation, I dropped two of these in my water cool, full of rain water I catch to water my plants. Those babies that be moving in the water were dead in a few hours. After a day or so, I no longer see the parents flying around either. No bum, no mosquitoes, my life is a much happier place now. Thank you for a product that works like you said it would. Sincerely, Farro Wife The comedian

Awesome stuff!
This stuff really works. I used to go sit on this tire that we rarely move. It's hard to imagine that it's there for looks now. Anyway, it's become a seat in the shade and has always had mosquitoes inside it because of the stagnant water. The simplicity of dropping a couple of these things in that water is self explanatory. They work. No mosquitoes!

Knocks Down the Population
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.

These WORK!
These are necessary for the maintenance of my rain barrel. All standing water, fountains, ponds and barrels are subject to mosquito infestation. Mosquito Dunks are harmless to pond fish, pets, plants but deadly to mosquitos in the larval stage. Use Mosquito Bits to make “tea” using cheese cloth. Water plants with the tea to kill fungal gnats too!

Use for fungus gnats too!
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!

They work very well in my pond and don't harm the wildlife in it! Happy frogs!
So easy to use...just throw one in any standing water source and they last several weeks!

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.

Tengo aproximadamente un mes que apliqué medio aro de control de larvas en un estanque de aproximadamente 120 litros y desde el tercero o cuarto día empezaron a aparecer las larvas muertas. En estos días no he visto larvas en el estanque. Falta comprobar si es efectivo durante 60 días. En este momento me parecen que son altamente recomendables para controlar las larvas de mosquito y evitar las enfermedades que transmiten.
