FYI: The most common source for "pantry pests" come into the house in pet food/treats and bird seed. Keep these items tightly sealed outside the house (in a garage/shed) if you don't want them invading your kitchen. Or have your kitchen professionally sprayed for insects on a regular basis.

Try to vacuum the moths off the ceiling. I can place a long wand on my Dyson so I can reach my ceiling without a ladder, along with a brush attachment, and would use something like that for removal from a ceiling. Thoroughly clean the kitchen shelves - vacuum any cracks and crevasses where small amounts of food particles can hide that would feed the pests. Dump the contents to the vacuum/bag outside so they don't end up thriving in the vacuum to re-infest your home.

I've practiced home food storage for decades, including hundreds and hundreds of pounds of grains/seeds/beans, and have never had an insect infestation. I practice good storage principles and store everything in airtight or vacuum-sealed containers. Insect pantry pests AND their eggs cannot survive the oxygen-free environment of a vacuum-sealed jar/bag/canister. Everything from the store purchased in plastic bags, paper bags, and paper boxes, needs to be stored in something that can be sealed with an air-tight lid since pantry pests (once you have an infestation) can chew through plastic bags (like pasta comes in) and paper bags (like flour bags).

The up side.... I took a class at the Extension Office about "pantry pests" and the entomologists said the insects were a good source of B12, which can be important in the diet of vegans and vegetarians, albeit somewhat gross! Swallowing a few gnats when you are out in the garden or on your bike is another way to supplement B12 in the diet, according to a class I took about vegan/vegetarianism.
