Wood pellets don’t last forever but they last longer than most people think.
If stored properly, Traeger pellets can stay usable for 6 months to 2 years.
In the grill, a 20-pound bag can power anywhere from 6 to 20 hours of cooking, depending on the temperature.
In this guide, we explain what that really means for your backyard cooks.

Shelf Life: How Long Do Traeger Pellets Last in Storage
Traeger pellets are made from compressed hardwood sawdust.
They contain no fillers or chemical binders.
That’s good for flavor but it also means they absorb moisture easily.

Stored Properly
If kept:
-
In a dry space
-
In a sealed container
-
Off concrete floors
-
Away from humidity
They can last a year or more without problems.
Stored Poorly
If left:
-
In a damp garage
-
In an open bag
-
Outside in humid weather
They may swell, crumble, or turn into sawdust within weeks.
Moisture is the enemy.
Once pellets expand, they won’t feed correctly through the auger.
Worse, they can cause jams.
Quick Test
Drop a pellet in a glass of water.
-
If it breaks apart quickly, that’s normal.
-
If it was already soft before the test, it’s compromised.

Burn Time: How Long a Bag Lasts While Cooking
This is what most grill owners really want to know.
Burn rate depends on temperature.
Here’s a simple breakdown:
-
180–225°F (Low & Slow): ~1 pound per hour
-
250–325°F (Roasting): ~1.5 pounds per hour
-
400–450°F (High Heat): 2–3 pounds per hour
Since most Traeger pellet bags are 20 pounds:
-
At 225°F → about 20 hours of cook time
-
At 300°F → about 13–15 hours
-
At high heat → as little as 6–10 hours
Cold weather increases pellet use.
Wind does too.
A well-insulated grill burns fuel more efficiently.

How Long Do Pellets Last in the Hopper?
Technically, pellets can sit in the hopper for weeks.
But that doesn’t mean they should.
If your grill lives outside, humidity can sneak in through small gaps.
Pellets left in the hopper for long periods may absorb moisture even if they look fine.
Best practice:
-
Empty the hopper if you won’t grill for several weeks.
-
Store pellets in an airtight bin.
This reduces the risk of auger jams and startup failures.

Signs Your Pellets Have Gone Bad
Watch for:
-
Excess sawdust in the hopper
-
Pellets that snap easily instead of breaking clean
-
Difficulty igniting
-
Excess ash buildup
-
Inconsistent temperatures
Good pellets feel hard and solid.
They should snap with a firm break.
Flaws but Not Dealbreakers
Traeger pellets are well-compressed and consistent.
But like all hardwood pellets, they are vulnerable to moisture.
They are not waterproof.
They are not designed for long-term outdoor storage.
If you live in a humid climate, you’ll need better storage habits than someone in a dry region.
That’s not a Traeger-specific issue. It’s true of all BBQ pellets.

How to Make Pellets Last Longer
A few small habits go a long way:
-
Store in a sealed plastic bin with a lid
-
Keep indoors when possible
-
Avoid storing directly on concrete
-
Buy only what you’ll use in a few months if humidity is high
If you grill weekly, buying multiple bags at once is fine.
If you grill once a month, smaller, fresher purchases may make more sense.

Bottom Line
Traeger pellets can last up to two years in dry storage.
But once moisture gets in, they can fail quickly.
In the grill, expect a 20-pound bag to deliver 6 to 20 hours of cooking, depending on temperature.
The key isn’t just how long they last.
It’s how you store them.
Keep them dry, and they’ll reward you with steady heat and clean smoke every time.
