Why are there maggots in clear water?

The main reason why there are maggots in clean water is the influence of weather conditions on insect reproduction. For example, rising temperature, heavy rain and high humidity may lead to a large number of red nematodes. The red nematode mainly crawled into the tap along the wall of the tap water pipe. If tap water is not used for a long time, red nematodes will multiply in large numbers. This is why at some time, even in clean water, you can observe maggots or other insect larvae.

Please note that although maggots in clean water usually come from the pollution of the external environment, in some cases, these larvae may also come from the natural pollution of water, such as microorganisms or organic matter in water. Therefore, keeping the water clean and avoiding not using tap water for a long time is helpful to reduce the problem of maggots or other insect larvae.
