A specially trained dog spent Wednesday inside the Tulsa Central Library sniffing out bed bugs.
The bugs were discovered on several chairs yesterday on the third floor.
So the library was forced to close for extermination.
Wednesday, a dog named Ms. Liberty Belle, was called in to check all floors for any remaining bed bugs.
The beagle is Oklahoma's only bed bug-sniffing dog.
Visitors who were in the library Tuesday are asked to call the health department with any questions.
The Central Library remains closed until further notice. Other libraries are open.
