There is a news of another bed bug scare at Tulsa's Central Library downtown.
Library administrators have sent an internal email to staff members saying someone found part of a "suspicious" bug.
It's not clear what kind of bug it is, but in the email obtained by News On 6, officials say they are not taking any chances.
Oklahoma's only bed-bug sniffing dog, Ms Liberty Belle will go back into the library after hours on Saturday. Because it could alter her smell, the library will not treat any of the floors until the dog can make the rounds.
The Central Library at 400 Civic Center closed for several days in mid-July after a bed bug discovery on some furniture in the library's third floor.
