Chris:
I would give these a try. Click the link, and there's a video showing the moths killed by these traps (which look just like yours...)

Also.... traditionally, people have used cedar as an insect repellent for years (remember cedar chests for storage?) I use cedar balls and/or discs in my pennant bins as an additional safeguard. I don't want to jinx it, but have never had a moth issue in 30 years of collecting ...

Hope this helps... And don't let them get anywhere near that Cap collection!!
