Human trade and movement of items that can contain these worms (for example potted plants and soil) has aided their movement across the world. Terrestrial flatworms are most diverse in the tropics, especially SE Asia, Australia, Africa, and South America. These worms are often variously called land planarians, terrestrial flatworms, or hammerhead worms (specific to a particular group see Identification section for discussion). Although most are fully aquatic, there are many species that exist on land in moist, terrestrial habitats, particularly those in the family Geoplanidae.

WESH received photos of a suspected New Guinea flatworm found in Grant, Brevard County, inside someone’s house.

This method may remove flatworms without damaging the roots of plants however, this method will not discriminate between native and nonnative species of flatworms.Ī University of Florida report said not only are they an invasive species that can cause real environmental damage, but they also are known to carry a parasite called rat lungworm that can cause a form of meningitis in humans.

Property owners may treat soil in potted plants that contain flatworms by soaking with boiling water for 5 minutes. Do not move plants from an area where New Guinea flatworms have become established and you do not want to introduce plants or plant debris into managed public lands or undeveloped private lands. We recommend carefully inspecting all new plants and/or gardening materials before bringing plants into a new area.

They can also be spread by machinery, vehicles, shoes, gear or equipment moved from one area to another. They are typically spread with agricultural, ornamental, and other potted plants, either in the living plant, cut landscape trimmings and debris, or in soil, sand, or mulch associated with plants or plant care.

New Guinea flatworms are a nonnative species to Florida and are not a protected species.
