take all of your packaged food (cookies, cereal etc) and put it in the freezer overnight.

wipe out your affected cabinets with a 4:1 water and white vinegar mix.

most stuff in ytour cabinets can be frozen.

we had this problem a few months ago.
it was bugs/moths that came in with sunflower seeds that we use for the birds.
EVERYTHING went into the freezeer............cereal, cookies, birdseed, bisquick, oatmeal, flour, sugar, cake mixes , crackers, chips, pasta.....EVERYTHING.
of course everything did not fit at the same time.
it took us 3 days to get all the stuff done.

we did not reload the cabinet until all had been frozen.
