The African giant snail, also known as the brown cloud agate snail, is a medium-sized and large-sized terrestrial snail. The adult shell is usually 7-8 cm long, and the largest can exceed 20 cm. It is the largest snail in the world. It is the intermediate host of many parasites and pathogens, such as whipworms, pinworms, nematodes, etc., which can parasitize the human central nervous system or cerebrospinal fluid and cause meningitis, which is extremely harmful. In addition to carrying viruses, their mucus or feces may also carry many parasites and pathogens, especially Angiostrongylus cantonensis, which can spread diseases such as meningitis.

Prevention and control methods of African giant snails

1, mechanical control

Snails can be hunted artificially at dawn, dusk, at night or after a thunderstorm, and their habits can also be used to trap and kill with food.

2. Agricultural control

Use agricultural cultivation measures to change the ecological environment.

3. Chemical control

In this respect, we can use the medicine "Tetraacetaldehyde" to control snails. Some people worry that the medicine will pollute the environment, but there is no need to worry about it. Because of its characteristics, crops will not absorb it.

4. Biological control

It has been found that many organisms can parasitize or prey on snails, such as bacteria, nematodes, arthropods, mollusks, mammals and so on. Toads, frogs, ants, birds, chickens, ducks and geese can be used to control African snails.
