About 1 year in the pantry, according to USDA FoodKeeper v128.
Lentils (dried) are shelf-stable at room temperature: cool, dry pantry, sealed — refrigerating after opening is optional and mainly preserves quality. Refrigerating it mainly preserves quality rather than safety.
Look for: 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. Those are the general signs for grains, beans & pasta — USDA FoodKeeper v128 publishes no spoilage note for Lentils (dried) specifically. Never taste something to test it — when in doubt, throw it out.
