Red nematodes Generally speaking, it is impossible for red nematodes to exist in clean and disinfected water. Users who use water tanks above the third floor or other secondary water supply facilities (such as reservoirs) find red nematodes in tap water. The main reason is that the water tank or other secondary water supply facilities are poorly managed and not cleaned in time, resulting in pollution, and the eggs deposited in the water tank hatch and develop into red nematodes. Users who directly supply water below the third floor find that there are red nematodes in the water, mainly because of the high temperature and humidity in summer, which are suitable for the growth of red nematodes. There are a lot of red nematodes in sewers and pipes. Every night, they often climb out of the sewer, climb to the outlet of the user's tap water along the wall of the pool and tap water pipe, and get together. When users use water for the first time in the morning, they flush it out, causing the illusion that red nematodes flow out of tap water. Secondly, if the faucet has been turned on for a period of time, there are still red nematodes flowing out, which may be related to the aging and corrosion of water pipes and the growth of microorganisms in water, reminding users to replace indoor pipes.
The key to prevent red nematodes is to clean and disinfect secondary water supply facilities such as water tanks in time, strengthen the management of secondary water supply facilities such as water tanks, and maintain, clean and disinfect them in time. General disinfection shall not be less than once every six months to prevent the growth of red nematodes in water; If red nematodes appear in the water, bleaching powder can be used to kill insects; Conditional users can also often use "84 disinfectant", bleaching powder, bottled household disinfectant and so on. Disinfect long-term wet places such as sinks and sewer pipes to prevent red nematodes from crawling out. In addition, if the household solar water heater is not used for a long time, the water should be completely drained, and attention should be paid to disinfection and cleaning when it is used again, otherwise it may breed red nematodes.
Most of the water worms are caught in the shallow water of river branches and silt ponds. Use a fine net to shovel it from the silt surface of the riverbed and two centimeters below the silt. There are a lot of water bugs in the residue after rinsing with water. Collect enough mud and earthworm mixture, put it in a big basin, fill it with water, and cover it for shade. After the earthworm is enriched on the water surface, it is fished out by hand and placed in two places. Earthworms are exhausted, and the rest is water and mud.
In the south, earthworms are often used as food for goldfish, koi fish and eel fry, and the price is higher. Some catch red worms, some wear conjoined Shui Bo, and some professionals wander in ditches where sewage flows through rivers and branches.
Red worm differential editing
Red nematodes generally refer to water worms, and they are still water worms when they grow up. That is, red worms become mosquitoes, shorter and thicker than red nematodes. Both of them are used to raise fish, and more people use red worms than red nematodes, because red worms have high nutritional value and are suitable for a wider range of fish. Most importantly, the growth environment of red nematodes is silt, and the possibility of carrying harmful bacteria is much higher than that of red worms.
