Food Storage Pest Prevention Checklist

Grains and rice: Freeze newly purchased rice, flour, and grains at -18C for 48 hours before storage — this kills any existing eggs; then transfer to airtight containers at room temperature

Airtight containers: All opened dry goods (rice, flour, beans, nuts, dried fruit, spices, cookies, cereal) must go into sealed glass jars or hard plastic containers — original packaging is not pest-proof

Monthly inspection: Check food storage areas once per month — look for live insects crawling, moth webbing, clumping, or fine powder piles (all signs of stored product pests)

If pests found: Immediately seal infested food tightly and dispose of it in an outdoor bin — do not just pick out the bugs and continue eating; eggs and feces have contaminated the entire package

Cabinet cleanup after infestation: Empty the cabinet, vacuum all crevices thoroughly, then wipe all shelves and interior walls with a 1:1 white vinegar and water solution

First In First Out (FIFO): Label food with purchase dates and use older items first — do not hoard more than 3 months of dry goods; the older food gets, the more likely infestation becomes

Natural repellents: Place a few bay leaves or dried chili peppers in cabinet corners — natural pest deterrents that repel rice weevils and grain beetles

Pet food: Transfer dry pet food from original bags into airtight containers immediately after opening — do not scoop directly from the original bag; pet food is a hotspot for stored product pests

Temperature and humidity: Keep food storage areas cool and dry — temperatures above 25C and humidity above 60% accelerate egg hatching; avoid placing food cabinets near refrigerators or stoves

Buy smart: Bulk bin dry goods (from open markets) are far more likely to carry pest eggs than factory-sealed packages — choose vacuum-sealed products whenever possible
