Mosquito Dunks 6's - Biological Mosquito Control

Yes they work great

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.

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.

I've noticed a slight decrease in the number of mosquitoes since using these, so they do seem to be helping. I think the key is using several around the yard rather than relying on just one, especially if you have a larger outdoor space. Keep in mind they also need to be replaced about once a month to stay effective. I use mine in a Home Depot bucket filled with water along with some grass and plant matter to attract mosquitoes to lay their eggs there instead of elsewhere in the yard. Overall, it's a good product and a nice chemical-free option for mosquito control.

These arrived promptly and in good condition. We have deployed them for 3 weeks now and we believe they are making a difference in the mosquito population. We put chunks of them in dark buckets filled with water and rotting vegetation to attract female mosquitoes. Four buckets around our standard suburban yard. In shady spots.

Seems to cut down some of the mosquito population

This is working. I am very happy about it. Didn't seem to have any negative effects on my duck.

Not sure yet. Wind keeps knocking the bucket over. So far so good. Will do a revision of my review in a couple weeks

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, 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.

They’ve been helping with the fungus gnat issue in my apartment (thanks to the one plant that infested the rest 😞). I’ve been soaking them in the water I use to water the plants (probably about 5 waterings in). I would say I only have 10% of the population left.

I put four of these tubs around our deck between our cottage and the lake with 1/4 of a mosquito dunk in each. After one month, we’ve noticed a significant decrease in the mosquitoes! The path to the lake was terrible because of the mosquitoes in June, but now one month later there are very few. I just added a second round of the dunks to each tub. This was a reluctant purchase but I’m convinced now!
