It is important to make sure that the seeds are kept in a cool dry area that isn’t prone to extreme fluctuations in temperature.  

To ensure that the seeds last for as long as possible, make sure that you keep them in an airtight container. 

This will help to keep them, fresher, for longer.

Again, they should be stored in an airtight container to maintain their freshness. 

If you are preserving the raw pumpkin seeds with a view to planting them the following year, they should be stored in a plastic container that has holes in the lid to prevent moisture from building up.

The rest of the seeds should not be eaten. 


In general, pumpkin seeds do not smell of very much. 

However, if you notice an unusual smell when opening the container, it is a good indication that the seeds have gone bad. 

If you can smell them, they are no longer edible and should be discarded. 

How To Store Pumpkin Seeds

Once you have opened the original packet of raw pumpkin seeds or if you have removed them from your pumpkin, it is important to store them properly. 

There are three ways of storing pumpkin seeds to help them remain fresh for longer. 

Airtight Container

This is a method of storing them that can be used at room temperature, in the refrigerator, or in the freezer.  

Plastic Bags

It is also possible to store pumpkin seeds in a plastic bag that has an airtight seal. 

A good example of this is bags with a ziplock seal. 

It is important to make sure that all the air has been removed from the bag before sealing it shut. 

This will help to maintain freshness for longer. 

Freezer Bags

An airtight freezer bag is a great option for when you are storing your seeds in the freezer. 

Again, with this method, it is important to make sure that you remove as much air as possible from the bag before sealing it.
