how long do they last and how many per square foot should I use?

I bought these to use in camper over the winter, had read the ingredients in them would repel mice. But, there is almost no fragrance in them at all. Not sure they will repel mice or moths. Might be just a waste of money. Just no smell. Sorry!!!

How long they last depends on how bad your problem is. I'm not sure about the square feet but I use two packages per drawer and for my closet I get the hanging ones and I use 2 hangers (they have 2 in each hanger). Mine usually last about 3 months. Once you get the problem under control, you can go to 1 in the closet and 1 in the drawers. Hope this is helpful and answers your question some what.

I found that they usually last 3 months and I put them in my closet where I have my wool clothes.

You're supposed to use one or two per square foot. They last for 3-4 hours realistically and more faintly for a couple days. We ended up giving up on these and spackling the cracks in the corners of the walls so they couldn't get in in the first places z

Depends on how hot the fire is. Outside we have them in a calor gas fire, and hopefully they will last forever. We have used them about twelve times and they still look as good as new. Hope this answers your question.

Our first batch lasted almost 2 years. Depends on how often you use them. We use about once per week.

I really don't know how much square footage it will cover. We only have about 10 square feet we use it on. It lasts quite a while. Sorry I can't be more helpful.

YOU CAN THEORETICALLY leave them on 24/7 for ten years and they will not only last but never downgrade...I could go into scientific data about it but it'd better if you go online and read because it is a very long date article...u have some very very very ofl old on my refugium that's been on all day everyday and they are as bright as the day I built then....

For me , they last about 4 months. I use them in a home repair business but must add that I do not use them everyday.

Mine are still effective after over a year of use and I still use it. Make sure to keep it indoor because it has the tendency to thickened.

I use for my entire 2nd floor of our house. Which is about 900 sq ft. 9 ft ceilings. I could probably use two for each floor but 1 does pretty well. I bought these for healing purposes as well as room deodorizes. I got sick of wasting money on glade plugins. Plus those chemicals freak me out. These work really well. Love 'em.

One, for the square footage it is recommended for. They worked well for me!

I can't really say. I've done quite a bit of repair and still have quite a bit left but my repairs are not one area, they are long scratches, roughed up areas etc. I've probably repaired around 6-8 square feet and have probably 1/2 can left. But it's a very rough estimate

I believe they are supposed to last for one year. I have been using mine for over 6 months now and it has barely changed in size.

I have 32 square feet of counter . I put on 2 coats of clear and had some left, but you should buy extra clear for the amount of sq. ft you have. Don't rush the job follow the recommended time between coats . Ours looks great.

General rule of thumb is 30 BTUs per square foot. This can change by some other factors up or down.

They last at least 4-5 seasons or more for me; if you place them carefully where the cedar can properly protect clothing, towels, sheets, etc., you should have no problem with them lasting an extremely long time. As long as you continue to smell the cedar, the protection will always be there.

I am still using it and I use them about once a week. If you wash them properly and sanitize every now and then they should last a while.

I get infestations regularly, I will use one of these for my 9 x 1 5 area soon as I see them starting up, I shut down the ventilation and carbon filters, leave your regular oscillating fans to move air around and seal up the room good, doesn't have to be air tight if its away from the living area, say a basement, but good enough to not waste it escaping. I let one go about 10 minutes after the lights go out and leave sealed till morning time, open up the room a bit to start venting and turn back on the ventilation. Hopefully your plus is outside the sealed area. Repeat two days later...that should work.
