As an avid gardener and outdoor enthusiast, I've tried countless products to combat mosquitoes, and I can confidently say that Summit Mosquito Dunks are an absolute game-changer! These little wonders have transformed my backyard into a peaceful oasis, allowing me to enjoy my plants and patio without being constantly harassed by those buzzing, biting pests. What I love most about Summit Dunks is their incredible effectiveness and ease of use. Simply drop a dunk into any standing water source – bird baths, rain barrels, decorative ponds, even puddles – and let it work its magic. Within hours, the Bacillus thuringiensis israelensis (BTI) in the dunks targets mosquito larvae, preventing them from ever maturing into adult, biting mosquitoes. It's truly satisfying to know I'm breaking their life cycle safely and efficiently. I'm also incredibly impressed by how long-lasting they are. One dunk lasts for weeks, even a month or more, meaning less frequent application and more time enjoying my outdoor space. Plus, they're completely safe for pets, wildlife, and beneficial insects, which is a huge priority for me. I can use them around my koi pond and know my fish are unharmed, and the birds still flock to my bird bath without any issues. Since I started using Summit Mosquito Dunks, I've noticed a dramatic reduction in the mosquito population around my home. I can finally relax on my porch in the evenings, garden without being swarmed, and even entertain guests outdoors without a single complaint about bites. If you're looking for an effective, safe, and long-lasting solution to your mosquito problem, look no further than Summit Mosquito Dunks. They're a five-star product in my book, and I recommend them without hesitation!

I recently used the Summit Mosquito Dunk Tablet in my backyard pond and was so pleased! It’s easy to use—just pop it in the water and let it work. It effectively controls mosquito larvae without harming plants, fish, or pets. I noticed a big drop in mosquito activity within days. The tablet lasts for weeks, making it a cost-effective and low-maintenance solution. Great peace of mind during outdoor season. Highly recommend

I love these. I put them in containers of water on the dark corners of my patio and in my birdbaths. By keeping them current I now have very few mosquitos and can go out without dousing myself in repellant. I had multiple swimmers in my birdbath a few days ago. A few minutes after putting in 1/4 of a new pellet they were gone. I'd like to give them 6 stars - except it is almost impossible to remove them from the packaging

The mosquitoes in my new greenhouse were violent until I put this product in a bowl on th ground. It definitely kills the bug and it's babies. Closed wet spaces farm as well as I would imagine a body of water. Great rec!

This little things have saved my marriage!! I love to be outside in the evenings, but my husband is a mosquito magnet. We can be sitting next to each other and I won’t get any bites, but my husband will be swatting the air and getting nibbled. He started refusing to go outside in the evenings. I love to be outside. I learned about building environmentally friendly mosquito traps and they are incredibly effective. You fill a bucket from Home Depot or Lowes (I picked Lowes because the blue blends in better that blaze orange does) half way up with water. You add some grass and leaves to make it swampy. Then you add half a dunk each month. It makes such a difference. I have them around our perimeter of our yard in bushes where they are concealed. I also have one right behind the outdoor seating where my husband sits (hidden behind the sectional). They make such a difference! He can be outside in shorts and is not bothered at all. Who knew mosquito dunks could be so romantic! If your special someone is delicious to mosquitos, show your love.

We have a drainage problem on one side of the house. We had drains created years ago but over the years they’ve silted in. When it rains, which it has done more often than usual this year, we end up with standing water on one corner of the house. Coincidentally we’ve noticed that mosquitoes are a much bigger problem this year as well. Until we can have the drains dug again, we needed a temporary solution to the mosquito problem. A relative suggested these and they were a good price, so I figured we had nothing to lose in ordering them. We’ve been using them for about a month now and the mosquito problem is significantly better.

I was a little skeptical, but I needed to try something. My 2 year old would be bitten at least 3 times or more in less than 10 minutes being outside. My wife also was getting bitten when working in the garden. I placed buckets approximately every 100 ft along the wooded perimeter and some around the house. Within a day there was a difference. I was amazed. My daughter could be out for long periods of time and no bites. This product is very effective. It could not be any easier to use. I do not know the full life cycle of these tablets. There are many factors of how much rain and sun that can impact how effective this type of product can work. I can say it has been over a month, and they still work and most of the tablets are still intact.

What Customer should know is that this product is fantastic! It works exactly as it says it does and is very easy to use. I use these every year in my rainwater buckets to kill and or keep mosquitos out of my yard. If you buy the little granules you can broadcast them in your grass to kill the larvae to prevent mosquitos from breeding and hatching in your yard. Excellent product! I would (and have) recommend this to anyone interested in keeping mosquitos away. Not only would I recommend it I have bought these for others who needed them but didn't have the means to get them! That's how well they work. And they are safe around wildlife, pets and kids when used according to the label directions.
