Here are five things to know about the flatworm

2. It is nocturnal and has no known predators. The flatworms are believed to be susceptible to citrus oil and white vinegar mixtures that are directly sprayed on them. Salt and slug repellent is another option to get rid of the flatworm.

3. The flatworm has been found in Texas, Florida and Puerto Rico. The southeastern United States is a great habitat for the flatworm due to the presence of snails.

4. The flatworm has the potential to carry parasites. The New Guinea flatworm is known to be a paratenic host of the rat lungworm. It is not advised to handle the flatworms bare-handed. It's recommended to wear latex gloves, or use a stick or disposable forceps.

5. The flatworm ranges in size from 1.6 to 2.6 inches. Both ends of the flatworm look similar, but the end with its head is narrower and has two eyespots. The underside of the flatworm is a pale tan and the upper side has a faint stripe.
