Well I am glad to report that whiting told me to toss the bag I bought and a replacement will be in the mail. He also told me that if I wanted, putting the contaminated feathers in the freezer for 3 weeks would kill the bugs.
Today while thinking about this problem, I realized something. I have used a kind of insect killer that you spray along your baseboards and cabinets and such. It is poison when it is wet, but when it dries it is not supposed to have any affect on pets or humans but still deadly to insects. Safe to use near food and in the kitchen. Well has anyone tried this in their material cabinets/rubbermades? Seems like it may be a better choice for me as I was worried about the pest strips toxicity. I remember I bought a gallon pump spray jug for about $8 at the garden center a couple years ago, even if I have to spray my containers once a year, it would give me reason to check everything out and cull unwanted materials. Any thoughts?
