The method described uses oxygen absorbers only, achieving an oxygen level below 0.5% for a prolonged period so insects die. Practical guidance covers suitability, risks for Prussian blue and certain colourants, and precautions for paper-based and small-scale object storage.","cbCaifTaudnUEcw2","https://ap.wps.com/l/cbCaifTaudnUEcw2","pdf",1420230,1,6,"English","en","# Introduction\n# Materials\n# Tools","[{\"question\":\"What principle makes anoxia effective for pest control in collections?\",\"answer\":\"Insects die when exposed to a low-oxygen environment below 0.5% for a prolonged period.
