It looks like a piece of gum or rubber stuck to the wall or the ground, but it is actually an egg cluster of the Apple Snail. These egg clusters are usually near a water source so that when they hatch they will fall into the water where hundreds of tiny baby Apple Snails will thrive and grow. These invasive snails are having a huge impact on the ecosystem of Louisiana's waterways. They are invasive and indiscriminate in their food source. They eat vegetation that fishing habitats depend on to thrive and survive. These snails, originally from South America were sold as aquarium pets in the United States. They were introduced in the wild when people no longer wanted their aquariums and dumped them into local canals and other waterways. They are currently in Louisiana bayous as well as in the National Wildlife Reserve. It is only a matter of time before they are in the Intracoastal canal which will only exacerbate the problem as they spread to many other waterways. There is no magic pesticide that can control these invasive snails.
