How to prevent mosquito and fly breeding during organic fertilizer composting?

A few days ago, a friend inquired about what to do if mosquitoes and flies breed during the organic fertilizer composting process. Today, we will investigate the causes and solutions.

cause analysis

Places with water are prone to the breeding of mosquitoes and flies. Areas with high moisture content such as rainwater, wastewater, and wet materials are all places where mosquitoes and flies survive and reproduce. Generally speaking, fly eggs can hatch larvae in an environment with a humidity of over 35%, and the optimal hatching humidity is 70%. In addition, adult flies have a tendency to lay eggs on immature materials. Fresh compost raw materials cover the surface of the pile, the lowest layer of the pile (with high moisture content), and the periphery of the pile (where mosquitoes and flies can easily lay eggs), all of which are places where mosquitoes and flies can easily breed. Sometimes maggots can also be found growing inside the pile.

Solution measures

Growing maggots or pupae during the fermentation process is not good, but it is still common. Due to the possibility of parasitic insect eggs in the material being placed, the eggs will naturally become extinct as the fermentation temperature increases and the food source matures. Measures such as rapid processing of raw materials, increasing the frequency of flipping (once every 4-7 days), flipping the bottom material to the middle and upper layers, and covering the surface of the static pile with more than 10cm of decomposed organic fertilizer (to isolate mosquito and fly eggs) can also be taken to reduce or eliminate the production of mosquitoes and flies.
