Do a quick pantry check every few weeks, which is how often USDA suggests checking your canned goods, and give the shelves a full empty-and-wipe clean every three months. Clean sooner if you find a spill, sticky jars, or any sign of moths or small beetles. An infestation means emptying that cupboard the same day.
Three months isn't arbitrary. University of Minnesota Extension suggests buying dried foods in amounts you'll use within two to four months to keep pantry pests out, so a quarterly clean lines up with the point where anything older should be getting used or questioned.

The quick check (five minutes)#
Do this when you put groceries away. Bring older items forward and put new ones behind them. Then look for:
- Cans that are bulging, leaking, rusted, or deeply dented. USDA says not to buy cans in that condition, so don't keep them either. Never taste food from a suspect can to check it.
- Bags and boxes with holes or open seams. USDA's advice on storing dry goods is to check packaging for holes that could let in moisture or bugs, and to move foods like rice, cereal, and pasta into plastic or glass containers for extra protection.
- Sticky rings under bottles of oil, honey, and syrup. These attract ants and glue packages to the shelf.
- Anything labeled "refrigerate after opening" that got opened and put back.
How to deep clean a pantry#
- Work one shelf at a time so you aren't covering the whole kitchen in packets.
- Take everything off and set it on the counter.
- Vacuum the shelf with a crevice tool, getting into the back corners and the gaps along the walls. University of Minnesota Extension recommends vacuuming cracks and corners specifically, since that's where spilled flour and crumbs hide.
- Wipe the shelf with warm water and a little dish soap, then dry it. Let it air out for a few minutes before anything goes back.
- Sort as you return items. Toss anything stale, smelling off, or in damaged packaging. Group by use: breakfast, baking, snacks, cans, sauces.
- Wipe sticky jars and bottles before they go back on a clean shelf.
- Wash and fully dry any storage containers before refilling them.
Extension's guidance has one surprise: washing shelves with bleach, ammonia, or disinfectant doesn't prevent insects, and those chemicals can be dangerous if they get on food. Soap, water, and a vacuum are all a pantry needs. Treat the cupboard doors themselves the way you would kitchen cabinets.
When you decant into containers, keep the product name, best-by date, and cooking instructions. Cut the panel off the box and tape it to the jar, or write it on masking tape. If there's a recall, you'll want the lot code too.
How long does pantry food last?#
Dates on pantry food are mostly about quality. USDA's food product dating page says that except for infant formula, dates aren't an indicator of safety. That doesn't mean old food is good; it means you judge it by condition and storage, not the date alone.
USDA's shelf-stable food chart gives these quality guidelines for unopened food:
| Food |
On the shelf |
After opening |
| High-acid canned goods (tomatoes, fruit, juice, pickles) |
12 to 18 months |
5 to 7 days in the fridge |
| Low-acid canned goods (soup, beans, vegetables, meat) |
2 to 5 years |
3 to 4 days in the fridge |
| Rice and dried pasta |
2 years |
3 to 4 days in the fridge, once cooked |
| Home-canned food |
12 months |
3 to 4 days in the fridge |
Storage temperature matters more than people expect. USDA says canned goods keep best below 85°F, and temperatures over 100°F are harmful to them. A pantry that shares a wall with the oven, or a cupboard above the fridge, runs warm. Keep cans somewhere cool and dry.
What to do if you find pantry moths or bugs#
Small moths fluttering around the kitchen, silky webbing in a bag of oats, or tiny brown beetles in the flour all mean the same thing: something in the pantry is infested. University of Minnesota Extension lays out what to do:
- Check every susceptible food, not just the obvious one. Pour suspect products onto a baking sheet or shine a flashlight across the top. Pantry pests can get into unopened paper, thin cardboard, and plastic-wrapped packages.
- Throw away anything infested.
- Vacuum the shelves thoroughly, especially cracks and corners, then empty the vacuum or throw out the bag so the bugs don't come back out.
- Store what's left in sealable glass, metal, or heavy plastic containers, or in the fridge or freezer, until you're sure the problem is gone.
- For food you're unsure about, freeze it at 0°F for at least four days, or heat it in a shallow pan in a 130°F oven for at least 30 minutes.
Skip insecticide sprays in food cupboards. Extension says they don't reach insects inside packages and any food they touch has to be thrown out. Bay leaves and spearmint gum don't work either.
Seeing the odd moth for up to three weeks after a clean-out is normal. If you're still seeing them after that, there's another infested package you haven't found. Check the less obvious places: birdseed, dry pet food, dried flowers, and decorations made from seeds or corn. If you keep pet food in the pantry, inspect it every time.
Keep the fridge on the same rhythm#
Your pantry clean is a good moment to check the fridge too, since opened jars often move from one to the other. The refrigerator has its own cleaning schedule, and doing both on the same day saves a trip.
A quarterly ChoreLists.com reminder for the pantry, with a note listing which shelves you did last time, keeps the job from turning into an all-day project.
