Decant into an airtight container — pests chew through packaging“Stored product pests can easily penetrate thin or broken packaging.” — NC State Extension
Unopened dried pasta keeps about 2 years in the pantry“Rice and dried pasta — 2 years (shelf) — after cooking, 3 to 4 days in the refrigerator” — USDA Food Safety and Inspection Service

How to tell if Dry egg noodles has gone bad
Specific to Dry egg noodles, published by NC State Extension:
Webbing through the noodles — that means moth larvae“When larvae are feeding, they produce a lot of webbing across the infested foods which makes damage easily identifiable” — NC State Extension
Shed skins or gritty specks of frass in the bag“Larval activity can be identified by the presence of silk or webbing on contaminated foods, as well as by the presence of shed skins and frass (excrement).” — NC State Extension
Small beetles in or around the packet“This beetle can infest a wide array of stored products. Examples include cake mixes, candy, cereals, cocoa, cookies, dog food, egg noodles, grits, macaroni, spices, yeast, etc.” — NC State Extension
And the general signs for grains, beans & pasta:
A rancid or musty smell
Insects, webbing, or larvae in the package
Clumping or visible moisture
Mould, or a slimy surface on cooked grains and pasta
The first list is quoted from NC State Extension, with the page each line came from linked beside it; the rest are the general signs for grains, beans & pasta. Never taste something to test it — when in doubt, throw it out.
Air and warmth are what shorten an opened item's life — the right container buys back the days the packaging gives up once the seal's broken.
About 1–2 months in the pantry, according to USDA FoodKeeper v128.
