According to Chitty, the population in Pasco County likely originated from the illegal pet trade. Giant African land snails are illegal to own as pets in the United States. But some exotic pet owners still keep the invasive pests. If the owners discard them into the wild or accidentally lose them, they can quickly establish a foothold, feeding on over 500 different plant species and even consuming the paint and stucco off houses as a source of calcium.
Chitty said the department is currently investigating the population and determining how many snails are in Pasco County. The snails are native to east Africa and can grow up to 8 inches long.
The quarantine took effect June 25 and prevents residents from moving the snail or related items, like plants and soil, in or out of the designated quarantine area. Residents who think they have spotted a giant African land snail are advised to call the FDACS hotline and avoid touching the snail without gloves on due to the meningitis risk.
According to Chitty, FDACS plans to spend three years eradicating the population in Pasco County, using the pesticide metaldehyde to treat the soil.
