do they have an expiration date?

I don't remember, as I've already sent them back. But we bought them on Prime and used them within a week, so I can't imagine they were expired...

There is no expiration date printed anywhere on the box or individual patches.

I'm not sure but I have used the same box for the last two summers and they still work just fine

I dont remember but they weren't expired. I've ordered more than once and all were prior to expiration.

I've been purchasing these for a long time from Amazon, and they are always well within their expiration date. The ones I have now expire late in 2015, but these might have an even better expiration date. I guess to get the exact answer to your question, you could call Amazon.

I can only tell her that they have a long expiration date... But absolutely doNot buy if expired.

I believe they do. Products do not last long. They always have an expiration date. Mine says 11/17.

I gave my last ones to a family member and I can't remember if there is. Most things do have an expiration date so I checked some sprays I have and they don't have an expiration date.

No they don't, they have no expiration date on the package when I received them, also I did not use some of mine in a few years, and the plants came up fine.

It depends......mine had over 2 years until the expiry date when I purchased them. Of course, studies have shown that the expiration date is not absolute and can be safely used well beyond the date printed on the package.

I believe they don't have an expiration on them. They seem to last forever.

Mine does not have an expiration date. I have never worried about it. They still seem to work.

Yes. The ones I ordered a couple of months ago (in 2014) don't expire until July 2017.

They do have an expiration date...it's very hard to find it on those boxes and sometimes it's not even there at all. But they do go stale. Ask the seller to supply an expiration date for you.

No, not at all! These are extremely fresh from the factory! Will check expirations tomorrow and give you the exact date.

I don't recall seeing an expiration date on them, but I used mine for 3 months and they worked great.

Yes, there is an expiration date. Mine was almost a year from date of purchase.

No, they are current ones. I have a box on hand and it expires 02/17. I hope this helps.

Yes, there is an expiration date. Typically they are good for a year or so. Mine did not expire until 2016.
