The reason why snails are harmful, unkillable, and difficult to preventOn the one hand, shelled snails belong to snail mollusks, not to our common harmful insects, if we farmers use the usual insecticides to kill insects to control snails, it is impossible to kill and get rid of snails;

On the other hand, because snails will crawl everywhere on the surface of crop leaves, fruits, stems and other surfaces and leave polluting mucus, thus bringing pollution and diseases to fruits and vegetables; It will gnaw and bite on the fruits and vegetables, so that a large number of holes appear on the fruits, stems and leaves of melons, fruits and vegetables, or the fruits and vegetables are uneven and uneven, so the snail will seriously affect the yield and appearance quality of fruits and vegetables.
