The giant African land snail (Achatina fulica) is a threat to the sustainability of crop systems and native ecosystems, having a variety of negative impacts on native fauna, from competition for resources to the spread of diseases to direct herbivory of native plants. Native snails in fragile island ecosystems such as Hawaii and the French Polynesian islands are particularly susceptible to the negative effects of A. fulica and other introduced snails. The best way to prevent the further spread of A. fulica is by strengthening international quarantine systems.
This species has been nominated as among 100 of the World's Worst invaders

Suggested preventative measures must include strict quarantine measures to prevent introduction and further spread. Many methods have been tried to eradicate the Giant East African Snail. Generally, none of them have been effective except where implemented at the first sign of infestation. Methods include hand collecting, use of molluscicides, flame-throwers, and the failed attempts at biological control discussed below. In some regions, an effort has been made to promote use of the Giant East African Snail as a food resource, collecting the snails for food being seen as a method of controlling them. However, promoting a pest in this way is a controversial measure, as it may encourage the further deliberate spread of the snails.
One particularly catastrophic attempt to biologically control this species occurred on South Pacific Islands. Colonies of A. fulica were originally introduced as a food reserve for American GI's during the second world war, but naturally escaped. A carnivorous species from East Africa, a known predator of the East African Land Snail was introduced, but instead heavily predated the native Partula, causing the loss of some species.
