What can kill mosquito larva?

Answer 1

There are fish that eat these little bugs. If you have a pond and need to have these pests gone these fish can do it for you. Killing these is easy if you can dump the standing water they live in. They need the water to live and grow.

Answer 2

You can disinfect water that contains mosquito larvae. More bleach is required the older the larvae get. Older stages of larvae require a lethal dose of 250ppm so it is best to use this concentration as a one-off treatment. CloroxTM is 5.25% w/v sodium hypochlorite so this equates to 4.76 ml of bleach and made up to 1 liter of water.

Or just under 2 tablespoons (or 24 ml) of bleach per 5 liters of water.

This can be followed up with weekly doses of 50ppm bleach (or approx. 1ml of bleach per liter).

It is better to clean the container first, wherever possible as this will also help to remove the nutrients in the water that the larvae feed on.

Answer 3

Pest control is important. How to kill insects in their larval stage depends on what insect they are to become, however, many stores carry general full cycle insect treatment for pools.
