What is the shelf life (expiration) of Pyrethrin Dip? I understand insecticides (like Pyrethrin) are very stable products for long periods of time.

I'm not sure what the shelf life actually is, but I have had a bottle for 4-5 years, and it still works well.

Cabuca, you are correct. Mind you Pyrethin is a natural organic compound normally derived from Chrysanthemum cinerariifolium, (a plant actually from the husk/shell of it's seeds). There is no expiration date listed on the nomenclature of my bottle of Adams. Hope this helps, note this dip, even though revered as the safer alternative to other organic/chemical insecticides/repellents; this insecticide can be fatal or harmful to you, your family, and pet(s) if not applied/mixed correctly.

Generally pyrethrin products are stable for about 2 years if stored per the manufacturer's instructions.

I keep mine in a cool, dark place and its still good after a few months. I don't see why it wouldn't last nearly indefinitely providing it doesn't get contaminated with any foreign substances. Maybe keeping it in the fridge might help with this.

Considering it is a natural bee product, the shelf life should be more than the normal 2 years for other drugs, because bees are really amazing about preserving their own products,so i would say you are safe for at least 2 years, i am not an expert and i bought mine awhile back and have already used it and dont have the bottle to check for expiration date. You shouldnt be hesitant to buy it because of this reason only, and one bottle won t last too long, since personally i use it for everything, including my dogs. Hope this helps, good luck!!

Sorry to be slow in responding. Product I bought in July has expiration date of Sept. 2014. Good shelf life.

I bought this product and it was package and seal properly. The item were a couple of months away from being expired. I continue to use the product beyond that and have not had any negative effect from it..... I know a scientist who told me regarding any products we buy, as long as you keep things in the right temperature(i.e.....not dry condition) that such items can last beyond the manufacture expiration date. I hope this help. Good Luck.

There is no posted expiration date. I assume it lasts forever...we'll maybe not forever but I'm sure for a good while.

If you keep this in a dry cool place, it should lasts for years. That being said, each lot has their own expiration date printed on the packaging. Right now they are set at 2 years after manufacturing. We understand that not everyone will use the product expeditiously and we continue to work with packaging and suppliers to increase shelf life.

I'm in agreement with Mr. Milligan, somewhere near forever. In all cases, shelf life is affected by extremes in temperature. Personally, I try to rotate similar products on a 2 to three year cycle.

I think it depends on your location. If your location has a warm climate you shoud best keep it refrigerated, and the same if you will not be using the whole contents of the bottle for a long period of time. Taken from Wolfcreekranch: "Vibactra Plus has a shelf life of 4 years (longer if kept in a cool dark place)."

Are you asking - what is the expected shelf life of this product? Or are you looking for an exact date? Because each bottle has its own expiration date, just as you would expect to find on food, drugs, etc. I am not sure of your question.

I've always considered it to be the date when the chemicals start to break down on the film. Of course with film, if it has been kept at lower temperatures such as in a refrigerator, the longer it should last, but I've never seen a chart as to how much longer. Really, it's a chance we all take when buying products with a shelf life out of date. This is such a great film, I would probably buy it if it has just run out....and put it in a refrigerator.

Ordered mine August 12, 2013. Exp. Date on jar says 7/14. Instructions indicate it holds 180-360 days supply, depending on whether you give 1 or 2 scoops (included). This is no guarantee that a new order would still expire in July; it may have a much longer shelf life, but all I can give you is my experience with the product. By the way, it does work quite well, particularly if you've got a dog with diarrhea problems... clears that right up. Also, relative to other products this one is MUCH less costly, so even if you had to throw it out halfway through the jar, you'd still be money ahead. Our vet sells a product that costs over a dollar a day.

Always go by the expiration date! Which should last a long time. I have refilled my several times in a short period, we grill alot with friends and family and this is easier and less messy.

I believe the instructions tells you to dispose of what is left but I have used it up to a month later. You need to pose this question to the maker of the pesticide if you want a legal answer. Thanks James

I have never had any expire. My husband is a mosquito magnet, and he loves this stuff. It works well for him and also for our grandson.

The manufacturer states that the shelf life is 18 months when I called them. I am not getting good results from my tests. Non of the tests show any color after several tries. The manufacturer is sending me some FRESH test samples. I hope that solves the problem. I notice that one of the other commenters also has clay soil.

Apparently there is no expiration date on the jar. Only thing I can think is that it's supposed to be only a month's supply, so shouldn't have a chance to go bad. PLus, there isn't much in this stuff that could go bad. I find it lasts a little more than a month for my guys, and they do love it. It seems to work; my boys are healthy and happy. Hope this was helpful.
