There's also a chance they're coming from the OTHER direction. Egyptian moths (pantry moths) can affect the chiles outside, infesting them with eggs. They then hatch & the larvae bore through the bag heading OUT in search of greener pastures. Freezing the chiles for a minimum of 20 days makes them non-viable. Heating the dried chiles to 190 F for a bit can also do the trick. Cycling is the most effective- store frozen for a couple of weeks, thaw for a couple, & then freeze again. I've seen the moths in commerically prepared, sealed, glass containers as well. -Jim C Mild to Wild(R)
