Does Pepper Spray Expire?

Pepper spray does expire! This is because, the active ingredient in pepper spray, oleoresin capsicum (OC), can degrade over time. Additionally, aerosol cans will become less pressurized over time. With a high-quality pepper spray like Guard Dog Security, the shelf life for pepper spray is 4 years. 

It is also important to check the expiration date on the canister. Usually, the date is located on the bottom of the can. You should replace your pepper spray before it has expired to make sure it's still effective. 

The best practice is to replace your pepper spray or pepper gel earlier than the expiry date. By purchasing a new can every 1-2 years, you'll guarantee that you'll always be prepared with a fresh can of Pepper Spray or Gel!
