How long is it potent once it's opened?

Luckily, this stuff worked right away for my cats, so I didn't use it very long...maybe a few weeks. However, I just reopened the bottle of it to check for you, and it smells just as potent now as it was when I first used it. Trust me, this stuff is GREAT!

It didn't work at all for me. It may be that my new container had already died, but who knows? Best wishes, Robt.

I started using it just three weeks ago, but assume that if you keep the bottle tightly closed, it would last for many months. I keep kitchen herbs for months in tightly closed jars and they last for months. I add about 1/4 cup to each newly-filled litter pan each month and it's still working after three weeks. Hope that helps.

I've had a bottle for several years, and it still seems to have some effect.

I'm not an expert but I have had a partially opened bottle for a year and it didn't seem to lose it's potency when it was used.

Hi Debby... I re-read the can label and it doesn't say anything about cure time or wait after application. If I remember correctly I left the door stand open for a couple hours before using the microwave. Hope this is of some help.

The package tells that it loses it's strength in a day or so, I believe. My experience since I've used this product (about 20 years) is that it does not lose it's strength at all. I have some in my sprayer in the garage right now that is over three months old and I keep it because I know for SURE it is potent and will work JUST as well today as it did the first day I mixed it. Perhaps in a clinic they can actually test and see that potency decreases after time, but in my home or yard where I use it, the bugs would HAVE to disagree. :) I've never used old Demon to find that it did not work.

I can't really say for sure as I keep mine in the container. I would think so but I'm not sure how long the potency will last.

I've had the same bottle opening for 3-4 months and it's been fine. Not sure about 10 years. Ask the manufacturer.

At least two days. The more time you wait the better, but doesn't hurt after two days.

I don't understand the relevant of the question. My supplies was still within the used by date. Everything was in order but I just don't feel the potency that's all.

Eash bottle is sealed, so after you open it, you have 30 days to use the solution, if you don't you are to throw it away. One bottle lasts me a little over a week.

Hi Bandit, I am not totally sure how long it would keep its potency...with a pack of 4 Fila Mastiff's I go through it pretty quick...I do notice that in a spray bottle made up by gallon directions will lose its color after several weeks but the gallon does not and I haven't kept it in a closet. If it were me... I would and do keep all different things for my pack in stock for just the same reason you are asking this question I would say YES keep it on hand - for the cost it is a resonable investment for "Just In Case" Gina D

Indefinite...I bought mine well over a year ago and I would imagine it will still be something I'll have in my spice cabinet for another few years or so, at least. It's a powder like any other spice and should last until you use it up!!! I think the other answers are ok but, I know it will last more than 1 year from experience!

I have mine stored in a cool cabinet and I have had no problem with it remaining potent for a couple months.

I think it was about 7 months when I finished it. The pouring mechanism seems to keep it airtight after opened.

It has a fairly strong odor of its own, though not an unpleasant one, for about 24 hours. Then that odor disappears and so do any other odors in the area. This effect will last until the gel-like crystals shrivel up and get hard, which usually takes a month or more the way I use it, which is putting a half inch to one inch layer in a dish.

It usually takes about 15-20 minutes to effect. And then it's effect lasts for an hour.

It only takes a couple of minutes to harden but it also depends on the temp. when mixing it . give or take a couple of minutes not much more.

Same here as the below answer - we generally use it until it's gone - probably anywhere between 2-6 weeks after opening.
