Reduced moskitos
Seen a reduced number of moskitos in the area since using these. I pop one in my drain ever month.

Huge difference in mosquitoes and safe to use around kids
Before getting into the nitty gritty of my review it’s worth noting that I live in eastern NC and the mosquitos are insane compared to what I am used to when I lived in south New Jersey. My youngest child has skeeter syndrome.I started using these around mid-April of 2025 and the difference in our yard has honestly been massive. We went from getting eaten alive by mosquitoes to being able to stay outside in the evenings without being eaten alive by the bugs. My kids are out there for hours, sometimes until after 8pm, and we’re usually coming inside because it’s bedtime, not because of mosquitoes.One of my kids is very sensitive to mosquito bites, so finding something that actually helps without spraying the whole yard has been a big deal for us.I use them by breaking a dunk into 4 pieces and placing them in buckets of standing water around the yard (sometimes called “doom buckets”). The idea is that mosquitoes lay eggs in the water, and when the larvae hatch, they eat the BTI in the dunk and die. It works quietly in the background without much effort once it’s set up. I noticed a change in the mosquito population in my yard within 10 days. We had no new mosquito bites by week 3.I also like that it’s safe to use around kids, pets, and wildlife, which was important to me. I just refresh them about once a month and don’t have to think about it much in between. I have a calendar event in my phone that goes off every 25 days to remind me to toss in a new dunk piece.It’s not going to make your yard 100% mosquito-free, but it has made a very noticeable difference for us and made being outside much more enjoyable.Pros:Noticeably reduces mosquitoesEasy to useLow maintenanceSafe to use around kids and petsInsanely cheap compared to yard sprays that don’t workCons:Have to consistently use if you actually want to control mosquitosIf humidity is high (like within 24 hours of rain) mosquitos will still be hanging out around your property.You need to keep leaf litter cleaned up as mosquitos are attracted to the smell of decaying leaves.

If you want rid of mosquitos do this
Okay people if you come across this let me tell you exactly how to use theseGet a big bucketFill bucket a quarter way up with waterAdd in some fruit rinds like lemon orange etc and some leaves and grass from your areaAdd quarter of a dunkPut mesh over the bucket small enough so an animal can't get in but big enough for skeeters and flies and duct tape it downIt will cover a good size area and within a week no mosquitos anywhere near our house... we live in goa thats 💯 mosquito territory and we have one bucket in front and one in back and we have almost eradicated the little demons

superb product & great price
great product appeared to work straight away.Update:- 3/06/20 just finished this card of dunks, only use on a large Koi pond to maintain, all the aquatic bugs ( mozzies, black, fruit flies etc.... ) Again only use in the spring/summer here in the UK, very temperature dependant, but they certainly break up the life cycles, I bought an expensive U/V, professional light tube zapper, before finding these! The zapper has not been used for years?The downside is that the product only appears to be available in USA? So the price with shipping, has more than doubled? Why? This makes them prohibitive now. Looks like the Zapper will make a comeback!!!

Buen producto pero demasiado caro
Mata a las larvas de mosquito sin toxicidad para otros animales. Precio exagerado. En EEUU vale la mitad
