The snails were first sighted in the Donner and Chacahoula areas in 2008. A separate population was also found in Bayou Black. Apple snails have been sighted in other parts of Louisiana, including Gretna, Lafitte and in the Barataria Basin.

The first sign that apple snails have established themselves in a waterway is their eggs, Massimi said. The snails crawl out of the water during warm months and lay bright pink eggs a few feet above the waterline.

In the lush swamps of south Louisiana, tropical invasive plants and animals can cause problems in the environment, thriving to the point where they outgrow native species.

The aquatic snails can lay between 200 600 tiny eggs in one bunch. They continue to lay eggs as long as the weather is warm and could be reproducing through fall. They do have some local predators, including raccoons, minks, otters, wading birds, turtles and alligators. When they very small, even crawfish may eat them.

There are some effective pesticides, but they also kill all other species in the process, Massimi said.

Massimi said, and that likely how they reached Terrebonne, probably dumped into local waterways by a disenchanted aquarium owner.

Enola Elliot, a Houma resident, said her sister spotted the eggs near her house in Schriever. When she called to report them, wildlife officials told her to knock the egg clusters into the water.
