Mosquito dunks kill larvae. It's used as a mosquito population control in warmer areas. Me and a few neighbors used it this year with good results.

Get a 5 gallon bucket, add water/grass/leaves/dunk and let it sit for a few weeks. Every few weeks add more dunks. Put a stick in there so small animals don't get stuck when trying to get a drink.

Some horse barns put little fishes in the drinking water troughs. The fish eat the larvae. The horses ignore the fish.

They just started doing this in Florida to deal with dengue cases this year. Mosquito fish!

I've read this is safe for animals and bees.

Yes, the bacteria target mosquito larve.

Though:

- It won't stop breeding in other standing water

- Depending on where you live, it could decimate the food source of other animals

- It attacks all mosquito's not just blood suckers

- I understand that there are conflicting reports on its effects on amphibians. I'm not sure how reliable the negative reviews are, or if it is "big citronella" sourced scare, but you may want to be cautious of which water sources you use them in.
