how long does it stay effective and how do you know when to discard?

How long it lasts depends on how much moisture. I keep one in my car because I have a leak in my car and it rains a lot where I leave. Nice and dry inside until used up. About 4 months in the winter. You know it is used up when there aren't any more loose crystals. Pick up the tub and turn it sideways. If no movement in the bottom of the tub, replace it.

It starts as granules, when they turn to slush/liquid it is time for another bucket. The time it takes before you need a new one depends on how much dampness there is. I started with 4 containers/buckets and replaced them within two weeks. Now I have 1 in my basement and it has lasted 2 months so far and still doesn't need replacing. It is a good product.

Love this size, I have it in an unseated cabin and it lasted 5 months. I live in the wet damp Northwest. I had been buying the damp rid bags and they were lasting about a month in the winter, so this is so much more convent. You can easily tell where the water line is as the level gets darker and darker. I think that in the winter I will need to change it more often.... It really helped with that musty damp smell. hope this helps you.

first off make sure you followed direction to a T. Now take a breath. This is not an instant kill, the die off slowly. reapply if you think you need to but within 4 weeks they should be gone

my experience has been one hour minimum and up to 3 hours or so. It loses effectiveness after about 3 hours anyway per their instructions.

I use a fair amount of it and have never had any go bad, but to be realistic, 6 months. A good indication that it is getting old is drying time and viscosity will increase. Best environment for storage, tightly sealed in a cool dry area, the dryer the better.

The shelf life is the "best to use by date" found on most products. So you may not get the results you are looking for when using that product. I generally discard products after that date. Hope this is helpful to you.

Kind of a funny question because if you use it regularly as I do, it will be long gone before it can expire...no? Love this stuff, it does the job!

I'd recommend keeping it no longer than 3 months. The instructions says that it'll stay activated for 3-4 months. However, that doesn't that it'll last that long. If your water quality is really poor, I'd recommend you change the bag out sooner.

You can leave it in place or remove it to save for another time; it works as long as it stays intact. You will know when it doesn't work any more!

Not sure because I have a few bottles placed home and I don't take chances. I spray once a day 1 to 2 prays on a few places. But I think a bottle should last minimum a month but most likely 2.

Actually I think the longer you wait, the better it is. I found it too potent initially and would have thrown it out if it hadn't cost so much. But now - much later, it is better. Of course, there is a question of the point of diminishing returns to worry about, but I think it lasts forever. This one has an expiration date of February 10, 2016, but an earlier one I had lasted many years.

They last for a long time. I have had mine for over a year. I bought two bags and consolidated them all into one bag. As I use them I put the used ones in one of the nets (bags) it came in and toss them in the wash. That way I always have enough.

It lasts a long time. If you let it go completely out it may last 2 years.I try to change them once a year. And yes it will let you know its low.

So far mine lasted over a year. Just follow the directions as it says and I feel you will be very pleased with the results. I definitely recommend it:-)

A month or more if you use it every day. It seemed to work. It was my granddaughter who is in daycare. Now that a long time has passed without the appearance of lice in her class my daughter in law stopped using it. She is still on the original bottle so maybe even a couple months.

Honeywell tells me it will last from one to three years depending on how much you run machine. You should be able to tell because eventually the outside of the filter will turn sort of pale beige/yellow compared to the inside, which will still be white. You can also vacuum it to prolong life. Just use a soft brush and don't damage the paper folds.

I keep mine on my bathroom counter. It lasts about 6 months - maybe a bit longer. I use 2 pumps worth on my face 2x day. Awesome product.

I have had my one bottle over 6 months. I believe as long as you keep it sanitary by using fresh q tips to stir it and to apply than it will keep fresh until it is gone.
