Summit Mosquito Dunks 6's - Biological Mosquito Control

Bought this as I have a pond in the garden. I put half a dunk in and it seems to have gotten rid of the mosquitoes for now. Fish are still alive, so that's good too. Would recommend.

I didnt submerge mine underwater..I broke it in 3 pieces and let it float...there was rain water in my fish pond...I hadnt had time to clean it out so I was trying these pucks....thd pond was also full of mosquito larvae....I put the puck in the water in late afternoon. By the next afternoon...they hadnt really worked...but by the next afternoon every larvae was dead.. I read the fine print on the box...it recommends submerging them and they will work in 48 hours...this is true I found. I recommend them and will buy again when needed.

These work! The tiny wriggling mosquito larva were gone in 24 hours and haven't come back. I am using them in my 15 Gallon mini-garden pond tub inhabited by a Bronze Frog. Got rid the the mosquito larva and did not harm the frog or pond plants . I cut one dunk into 4 pieces since the pond tub is only 15 gallons. I do a 50% water change every week, treat the water used to refill, and add a fresh piece of Mosquito dunk once a month.

These work, but slowly. The female mosquito lays her eggs in the bucket where I have the Dunk set up. None of the eggs hatch, so there is a noticable reduction in the mosquito population, but it takes about 7-10 days to be noticeable. But it is safe for the environment and animals, so the wait is worth it.

Using this in my outdoor shower holding tank and definitely see a diminished mosquito presence. Great relief that we’re not bitten by mosquitos any more. These work great. Adding new one every month.
