A medieval abbey in Hungary is battling a beetle infestation threatening its ancient book collection. Workers at the Pannonhalma Archabbey are removing around 100,000 books for disinfection after the drugstore beetle was found damaging the volumes. The beetles are attracted to adhesives in books and have infested about a quarter of the abbey's 400,000 works. The library at the UNESCO World Heritage site houses Hungary's oldest books, including a 13th-century Bible and pre-printing press manuscripts. The abbey blames rising temperatures from climate change for contributing to the infestation. Damaged books will undergo restoration after the six-week, oxygen-free treatment to kill the pests.
