Review: 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.
Review: 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!
*by B***. on August 21, 2024*

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!
