Slimy Invader Alert: New Guinea Flatworm in Collier County

Residents near the fairgrounds are spotting the invasive New Guinea flatworm in driveways and yards. Originally from New Guinea, the flatworm likely arrived in Florida via potted plants and is now established in multiple counties.

Experts warn these worms can carry the rat lungworm parasite, which can cause serious illness in humans and pets if ingested.

Tips if you see one:

• Kill it with salt, boiling water, or crushing.

• Don’t cut it—it can regrow.

• Wash your hands thoroughly if you touch it.

• Hot water can treat potted plants to prevent infestations.

No need to report sightings—the species is already widespread in Florida.
