You might have purchased some old grain/noodles at the grocery store. Rice, flour, noodles, cereals...they are grain moths. Depending on the
length of time you've had the item in your pantry....they may have infested other items. Any dry grain, cereal even spices are at risk. One year I
bought some crushed red peppers at the grocery store...imagine my shock when I examined the container closer and saw the whole top part of
the bottle was filled with grain moths. IN PEPPERS! I threw the container away. YUCK!
You might have to check your dry grains and toss them. See if you bought any old dry goods at the store and toss them too. If you've had them
for the past couple weeks, it is possible they infected other boxes/packages/bags. You might have to throw away anything that's been stored in
your cabinets.
There must be a number for moths - pests - winged insects...and I hope you hit it good because putting up with that problem, you deserve it!
Good luck!!
