The library in Oak Park will reopen Thursday.
"We feel that taking every available action to ensure our public spaces are safe, comfortable and accessible for both our staff and community members goes without question here," the library said on Facebook.
Bedbugs were confirmed to be in chairs that were swiftly removed from the Oak Park library on Tuesday. Pest experts found no evidence of other bugs, but the library still decided to clean the building.
The pests found at the Royal Oak Public Library were cockroaches.
