How to Make Mosquito Larvae for My Fish

Growing your own mosquito cultures for your fish can be an easy and very affordable supplement to flake or pellet diets. In fact, with a single culture bucket, you can provide free food for your fish year-round with minimal time and effort. The following guide will walk you through the process, and make sure that you don̵7;t become a meal yourself in the process.

Instructions

    • 1

      Fill the bucket 3/4 full with dechlorinated water (or old tank water) and place in a sunny spot protected from falling tree leaves and other detritus, which can make it more difficult to collect larvae later on.

    • 2

      Stuff a piece of nylon stocking with a few chunks of apple, watermelon rind, lettuce or any other fruits or vegetables you have around. Tie tightly closed, and drop into the bucket. This will encourage the growth of bacteria and algae that the mosquito larvae feed on, and the stocking makes removal easier later on.

      Allow the bucket to sit undisturbed for five to seven days, and check progress. You should have plenty of larvae at this point, but if not, simply continue to check the bucket every three days. Always make sure there are no free-swimming pupae left in the bucket at any point.

      Strain the larvae through a clean piece of nylon stocking, reserving the water to place back outside.

      Feed your fish as many live larvae as they can consume in a few minutes, and separate the rest out into ice cube trays to freeze and feed later.
