We live in South Louisiana. I am convinced that sometimes it is humid enough here for mosquitoes to breed in the air! Ok, so it may not be that bad, but they definitely don't need much water to multiply quickly. We use several rain barrels around the yard for refilling the watering systems for the rabbits and chickens as well as watering our fruit trees and vegetable garden. While there are many fancy (and expensive) rain barrels that have mesh on top to keep mosquitoes out (and I'm not convinced that always works), we use mostly old trash cans with open tops to collect and redistribute water. This creates a huge problem for mosquito breeding!

Thankfully we found a simple and inexpensive solution that has worked AMAZING! This will set your bank account back by around 10 cents. That's right, less than a quarter! Go to your local pet store and buy a goldfish or two and drop them in your rain barrel. The fish will eat all of the mosquito larvae, taking care of the mosquito problem as well as feeding the fish. We have had our fish in the rain barrels for over a year now. We have never fed them, and they have lived through even the coldest temperatures when the rain barrels were completely frozen over! If you want to get even cheaper, you can always catch some minnows and put them in there, just be careful that you don't scoop them out when you are getting water- they blend in a lot better than goldfish do!
