2-Pack Summit Mosquito Dunks

Have used these with great success in a catch basin that always has about 1-1/2" of standing water in it. I suspend the dunk with a piece of twine from the grate that covers the catch basin so that it sits in the water. After the first use, the mosquitoes in that area of the garden were gone! Have to replace every month, or more often if there's a heavy, heavy rain (we're talking 3-4 inches). I like that it's safe to use.

Product arrived promptly and works as advertised...

We’ve had a lot of mosquitos in our yard this summer, and have a water feature (semi-moving water). We put these mosquito dunkers in it and the problem lessened. Then, because we misplaced them, the problem returned after a couple of weeks. We ordered more and will never let them lapse again! They work!

These work pretty good if you have any pools of water nearby. They did not eradicate my mosquito problem but I definitely noticed a difference after use.

The media could not be loaded. These work.Period.Add to any standing water and the mosquito population will dwindle. It's non toxic and safe around the kids and pets.The hole in the middle is useful to tie the dunk to the handle of a 5 gallon bucket so it stays afloat in the water.I also break these into pieces and add to the bird bath, chickens water dish and the water tray for my succulent collection.Try the dunks, have patience and pay attention to where the mosquitoes lay their larvae and these will work for you. The natural bacteria in them is safe for us and I do recommend these.

So these are two inch round donuts that look and feel like they are made out of sawdust. I saw online somewhere to put them in buckets full of stagnant water to eliminate mosquitoes. As they dissolve, I believe they release an enzyme that attacks the larvae that hatch from the eggs that female mosquitoes unwittingly lay in your buckets. Ultimately they are for use in larger stagnant ponds and large swampy areas, but I break one up and place in several various coffee cans that I have painted woodland colors and placed around the house and property. It takes about ten days for the mosquitoes to fall for the coffee cans, lay their eggs, and everyone to die off, but once the process starts, the mosquito population (and seems like a few other flying pests too) legitimately drops away to almost nothing. Best $25 I've spent all summer and I think I've only used three of them. One dunk covers like 100 sq. ft., so the top of a coffee can is about one sq. ft., so one dunk goes a long way. I put some more in the cans about every two weeks.*Pro Tip- Create some kind of small roof for you cans or buckets so when you have a heavy rain, they don't overflow washing all your stagnant water and dunks away.They work great for this, can't say enough about them. Safe for animals too.

Hard to quantify, but I did see a drop in mosquito activity after using. I used this in about 5 locations around the perimeter of my yard. Refreshed them every 30 days. I used this product in combination with Cutter backyard bug control (which I only used once this season). Normally, we could not go outside without spraying ourselves with bug spray, but this summer we were able to stay out well after sunset without spraying.

OK.....these do work, however they look gross when they get wet.(Imagine dark brown donut floating around in clear water- imagine the pool scenein Caddyshack and you'll get the picture). Not appealing whatsoever.Also, I had to cut them down, because of the amount of water I was using,it was a mess. These might work in a large Koi pond or something, whereyou do not need to cut, but not to good for smaller bird baths.
