LUBBOCK, Texas (KCBD) - Pet owners are urged to keep a close eye on their animals as the New World Screwworm crosses state lines.

Texas Governor Greg Abbott declared a disaster and escalated the state's response to the parasite after it was confirmed in South Texas last week.

The New World Screwworm is a parasitic fly which lays eggs on or near open wounds and body openings, such as the eyes, ears, nose, mouth or genitals.
