You can get picked up and carried away by the mosquitoes on my property. THEY GET BAD! But we have a 1/2 acre fish pond so I thought it was just going to be a fact of life. Ponds = blood suckers in the summer.

Swampy and perpetually muddy areas abound around us and this product worked very well to broadcast over the mud and still water when the dunks were too compacted to help. It rains frequently and when it does, these muddy areas get about an inch of water and are perfect for mosquitos breeding. I started early this past spring and was very pleased with the lower mosquito count this summer.

This product does an excellent job killing the mosquito larvae that grow in standing water. You can put it into puddles that have nowhere to drain after rain. We have far fewer mosquitos on our property since we started using this product.

I live in one of those towns that is in the local news every year for having illness-born mosquitoes.

I’ve been battling gnats in my houseplants for a looooong time. I live in a very dry climate, did not overwater, and let the topsoil dry out between waterings to no avail. I also tried those awful sticky traps – useless. I put all my plants in one room that the dog could not access and used a toxic spray on the soil (Liquid Sevin) many many many times. The gnats could no longer fly far from the plant but they could still breed and the spray did nothing to kill the larvae. So I tried these Mosquito Dunks Bits. I sprinkled them liberally on the top of the soil then watered well to wet all the Bits. I then let the plants dry out as I always did and I have no more gnats in less than two weeks! I wasn’t worried about the adult gnats because they die so quickly, but the Bits kill the larvae and break the cycle – if they can’t hatch, they can’t breed. I’m going to leave the bits in the soil and although these are supposedly safe for pets, I’ll put a little more new soil on top to discourage the curious dog from noticing the bits. I’ve frozen the new soil for a week and then thawed it (without opening the bag) in the hopes that the new soil doesn’t come with more gnats. I’m so happy I can have my plants all around the house now. I highly recommend these Bits.

Finally found a solution to getting rid of annoying fungus gnats from indoor plants! I just sprinkled a little into each potted plant (just on the soil surface) and watered the plants as per normal. Easy! After a short time, no more annoying gnats flying around in the house.

Works for me 🙂

Worked great for me – I live in a rural area with a lot of woods around the house. Just spread it around – specially in those still standing water spots (even if they seem dried out, or just “moist”). I had results after about a week. Will buy this again …!

Spill their cellular contents and let your plants drink them!

These are incredible for getting rid of fungus gnat in house plants. My recommendation is to take an old pair of panty hose, or a sock, and fill a tennis ball size mass inside of it with granules. Take a bucket and mix a spoon full of sugar and a light dose of fertilizer. Crush up the granules in the sock and then teabag the water. Get it nice and murky. Throw a few granules on top of the soil and you can treat with some of the bacteria broth right away, but I saw the deadliest results by allowing the broth to sit for a couple days so that the bacteria had time to multiply (warning: bacteria broths get stinky so use a lid). There was incredible bioactivity witnessed by bubbling on top of the water. This stuff is alive. Make the broth and this will spill the contents of all the larval cells. The bugs will persist for a couple days as the last batch flee the soil. Within 3 days or so, they were all dead. You can combine with these traps to see how many are left:
