Do these have an expiration date?

Yes, 6-8 months. We had ours on the dogs for about 9 months & they seemed to work that long. We will be buying more of them this spring.

I dont have the package anymore but I would assume if you kept it wrapped well, it would last a bit past the expiration date...

everything has an expiration date - legally required to. when i buy these flea/tick collars in advance i stash the exras in the freezer, still in their foil pouches.

Good question. They are shrink wrapped and there is no expiry date listed. Hopefully, they are fresh when bought.

I have no way of knowing that. All I can say is that the ones I ordered will expire on April 30, 2015....a full year after I ordered them.

No I don't see an expiration date. But if they are sealed and in a cool place they should last a long time.

Mine does not have an expiration date. I never use them if I have any left over in a years time. I believe they recommend that you consider them no good if you have had it a year.

Yes. I never had any problems with them and the expiration date is about a year in the future.

Expiration dates are tough to tell. Mine have always been 2-6 months out beyond when I have received them. That's my experience.

No expire date and they keep a very long time. I have kept them in a ziplock bag.

You would be better asking the seller. I bought these awhile ago, and mine weren't expired. Sorry

Yes they do, the ones I got last month expire on 11/01/2015. So they have a decent shelf life if left unopened. I refridgerate after opening.

They don't have a marked expiration date. I buy a set ahead and store them for several months without problems. I take 6 to 8 months to use up a set and don't know that I've had any failures. I'm not sure how they would do if you store them for years.

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

I believe they do have an expiration date but it would probably be dated out a year or two.Jessica CulbertsonPet Solutions

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.
