There is no expiration date on the box or the cans. I looked over it fully and found no dates. Please allow me up to 24 hours to answer a question if there are still a few days left on the auction. I have a condition that has been needing medical attention.
I just bought it last summer so I couldn't imagine it would be expired, even though there was no expiration date found. The reason it is listed is because I don't want to bomb my house for fear of it affecting my daughter.
