Invasive snails found in pond

Last week, Washington Lakes Watershed Association was alerted that Chinese mystery snails were found in Washington Pond. Chinese mystery snails, also called Japanese or Oriental mystery snails, are a highly invasive species which interferes with food webs and competes with native snails for food and habitat.

They can transmit parasites and diseases to waterfowl. Chinese mystery snails give birth to live young and quickly form dense colonies, which can clog the screens on water-intake pipes and cause other mischief. They are 100% bad news.

Identifying Chinese mystery snails

Chinese mystery snails are a good size – from 1.5 inches to 2.25 inches in length, from tip of shell to tip of whorl, think walnut-ish. Their shell color is olive green to brown. They have six or seven whorls and no banding. Their operculum (trapdoor) is hard and, when closed, it seals the snail inside its shell where it can survive for at least several days.

Amazingly, they have been documented as living as long as nine weeks out of water. Chinese mystery snails seem to select soft, muddy or sandy bottoms of shallow quiet waters.

These snails are not likely to be misidentified using this description.

How to prevent snail invasions

First, make sure boats, equipment, swim toys and all such items you bring into our waters are free of “passengers,” such as these snails and any other aquatic plants or animals that might be clinging or in the bilge.

Second, if you find Chinese mystery snails, do not transport them to any other location. Gather them into buckets if you can. If you can’t gather them, just leave them alone. Please send an email to and state the location and when you spot them; someone will follow up.

Getting rid of Chinese mystery snails

Getting rid of these destructive creatures is very difficult and will require a commitment for the long haul. The recommended way for Washington’s situation primarily is to hand harvest them into buckets and kill them. It’s imperative to make sure they will not survive to reproduce. They will dry out without water, but that can take a long time. Crushing them will kill them, also, but be aware that they stink extravagantly.

One resource suggests putting them in strong plastic bags, sealing the bags securely and putting the bags in the trash. Here, TriCounty sends our bagged trash to Eco-Maine, which incinerates it although the process can take a lot of time.

According to the Maine DEP, they can be composted live in a really specific manner that would ensure death, contain the smell and come up with a useful end product. Watch our Facebook page for the method and more updates at

The urgent, important, necessary response to these snail colonies is to make sure they are not introduced to any other areas. So far, they seem to be in the southern end of the lake.

Also, please watch for posters around town and on the town website with details about these snails.
