Minnows will eat mosquito larvae in large quantities causing devastation in their population. Minnows are heavy eaters that eat a large amount of food, especially with food they like.

Will Koi Fish Eat Mosquito Larvae?

Koi fish will eat mosquito
larvae when they come across them. Mosquito larvae are tasty and will fill their bellies, keeping them from hunger. Minnows will also eat other stages of mosquitoes.

These stages include;


The egg is the first stage of a mosquito life cycle. The female gets loaded with eggs and lays them in water. She tries to get stagnant water that will pose no harm to her eggs.

In the quest of getting a safe place to birth her eggs, she finds ponds, stagnant water, and other water bodies with little or no flowing current suitable for her eggs. After she lays the egg, the eggs grow and mature into the other stages of the mosquito life cycle before getting to the adult stage.

However, the journey does not get completed when they are in the same pond with minnows. Minnows start their eating adventure from the egg stage of mosquitoes. They will eat the eggs when they find them in the pond, putting the larvae at a low chance of survival.

The mosquito eggs are in the string, jelly-like forms, ready to hatch into larvae at the right time. Also, mosquito will lay about 100 to 200 eggs, providing more than enough meals for your minnows.


The pupa stage is the stage right after the larvae stage. When the eggs hatch, they hatch into the larvae stage of mosquitoes. However, larvae stage is the wiggling stage of mosquitoes, where they all perform the wiggling motion.

The larvae further develop into the pupa stage. The mosquito pupa, also known as the tumbler, floats at the top of the water. It is less dense than water, allowing it to float at the surface.

The pupa has two breathing tubes, called trumpets, that enable it to breathe oxygen while in water. Although the mosquito pupa does not eat, it is not in an inactive state. The pupa will also make a tasty meal for minnows, though they love to eat larvae the most.

Minnows will eat every form of mosquito they can find. There is a high tendency they will eat adult mosquitoes if they can find them. However, adult mosquitoes do not seem to be on the list as they are difficult to catch.

John has kept fish all his life (since he was about 5). He started with keeping guppies and fell in love with fish keeping almost straight away. That was 40 odd years ago. These days John still keeps fish and currently has two large tanks where he keeps many different types of fish such as Angelfish, Neon Tetras, Goldfish, Guppies and many more.
