Mosquitoes are a common problem in many areas because they breed rapidly and can carry disease. While there are chemical ways of reducing the mosquito population, these should only be used as a last resort because not only do they kill mosquitoes, but also destroy other beneficial insects.
A good way to reduce your mosquito population is by using goldfish. These fish eat mosquito larvae and can keep your area free of mosquitoes without the harmful effects of chemicals.
You can put Goldfish in your rain barrels to eat the mosquito larvae. Clever. Plus, fish poop is good for your plants. 😉 Be sure to follow the directions for acclimating the fish to their new watery home. And you might want to keep some fish flakes on hand in case there is not enough larvae to feed your gold fish.
