How to cultivate wigglers?

Wigglers are the larvae of Anopheles mosquitoes, which develop in water and breed a large number of larvae almost as long as there is a little sewage. Because they often wiggle in the water, they are vividly called "heel worms".

Its cultivation method: the use of plastic pots and old tanks, injected with clean water 4x5, put in a small amount of rice straw to improve the quality of water, can attract female Anopheles mosquitoes to lay eggs, and soon there will be a large number of larvae. After that, every 10 days, the wiggler was fished out with a net bag and fed to the fish. However, we should pay attention to control the period of collecting larvae, so as to prevent the harm caused by feathering into mosquitoes.
