No there is nothing wrong with the pest strips ,flea collars,cedar chips,microwave,freezer treatments. It seems this comes up often and we get the same replies. Many of us have hides,necks capes,and expensive feathers stored in 38 qt plastic tubs in a garage attic or basement and none of the above would help if we found one bugs. I believe the post said he found bugs in one plastic bag---the above would help that bag. I would treat everything---in my tying room with something better that will kill bugs eggs and larvae. I store my surplus with ENOZ moth ice crystals BILL
