Answer This Question

A:  Yes, you can use Mosquito Dunks in evaporative coolers. There will be no issues with your cat, as this is also recommended for use in animal watering troughs.

    Q:I've had the dunks in standing water, but I can still see new larvae. How does it work and how can I tell if it actually works?
    by|Aug 16, 2023
    1 Answer
    Answer This Question

    A:  The Dunks slowly dissolve releasing the active ingredient - BTI. Once it dissolves enough, it will start releasing the BTI and will continue for 30 days or more. To quickly kill mosquito larvae present in standing water, treat will Mosquito Bits which is a quick kill and follow up with Mosquito Dunks for maintenance. Or to help get the BTI in the water quickly, pulverize a Dunk and place the crushed Dunk in the standing water. It will not last as long but will quickly kill the mosquito larvae currently in the water

      Q:It's been 30 days, but my dunk has barely dissolved (and there does not seem to be any less mosquitoes terrorizing us). What should I do?
      by|Aug 12, 2023
      1 Answer
      Answer This Question

      A:  Dunks are designed to dissolve very slowly and it is not unusual for them to last far longer than 30 days. The Dunks will only kill mosquito larvae in the water in which they are placed. Mosquitoes breed in standing water so to reduce mosquito populations it is important to remove or treat any areas of standing water no matter how small. There are many possible areas where mosquitoes may be breeding such as slightly clogged rain gutters, the ridges in corrugated drain pipes, small amounts of water in storm drains and irrigation control boxes, and from the neighbors who may not be as diligent in removing and treating water as you are. Find and treat those areas of standing water and you will finally greatly reduce your mosquito problems.

        Q:How fast does this work? Meaning it's August. Can I put them out and have reduced mosquitos in 3 days? Or is this a "must place at beginning of the season" product
        by|Aug 10, 2023
        1 Answer
        Answer This Question

        A:  This product is used to treat areas of standing water to kill mosquito larvae. If you have water with visible mosquito larvae, we recommend treating that water with Mosquito Bits, a product with the same active ingredient that works as a quick kill for mosquito larvae. After that use the Dunks to maintain long term control over mosquito larvae in that standing water. This will work very well in August but keep in mind that this product does not kill the adult mosquitoes that are already around. To kill adult mosquitoes you would need to use a chemical spray specifically labeled for mosquito control use.

          They Really Do Work!!
          Mosquitoes love to bite me. But now I use Dunks. Put one in standing water, or just 1/2 or 1/4 depending on the amount of water to be treated. Lasts for month. Doesn't kills mosquitoes BUT, kills their eggs and larva. Will not harm animals. Love 'em, been using Dunks for 5 years!! To discourage already flying mosquitos, put several dryer sheets into your pockets. Works for me!

          Fungus gnats solution!!
          These helped immensely with my fungus gnat problem in my house plants. Just soak them in a bucket of water for 24 hours and water your plants. Worked wonders!

          Product works amazingly but I feel like the package claims you need to use way more than you actually do. We have a 28 ft wide pool, according to the package, we needed to use all 6 dunks but I opted to use only two and it worked like a charm!!

          We found the best way to eliminate mosquito populations was to keep a single point of water open (eliminate all others) and available (ours is about 3-4 inches deep and 2 ft2 surface area, and containing these mosquito "dunks." I replace the dunk every 2-3 weeks. Female mosquitoes choose the spot to lay their eggs and all larvae die, eliminating the problem at the source. We spend evenings on our Atlanta patio free of any mosquitoes.

            An excellent product for preventing and treating mosquito's in small bodies of water.  I have used these for years with tremendous success in a small outdoor fish pond as well as a variety of pots/planters filled with aquatic vegetation. My wife has a problem with water plants, she really likes them and despite my absolute hatred of mosquito's, she insists we maintain a small armada of planters outside.  These are a staple in my arsenal to combat the wretched flying bloodsuckers that are so often associated with stagnant water.  Here in Northern Virginia, I replace them on the first of every month from April to September.  They work very well as long as they are used according to the instructions.  Though they say they treat 100 square feet, I generally double the dose for a small pond of about that--adding two tablets at alternate ends of the pond.  This strategy has worked exceptionally well with no detriment to the plants or fish.  For smaller applications, one dunk does the trick.

            MOSQUITO DUNKS really work
            These MOSQUITO DUNKS really work and they are safe for birds and pets. They are not toxic and work as a biological control. We live on the Texas gulf coast and we have been using them for at least five years. Since we have been using them we haven’t seen a wiggle tail in or bird baths. We normally add ¼ of a “dunk” per bird bath every six weeks throughout the 9 months of summer we have here. The dunks come in a sealed up bubble pack that lets you open and remove them one at a time. We store all the unopened and opened dunks in an airtight plastic bag. They will crumble if you let them get damp.
