I just purchased these and need to know when once 'opened' how long is one of the boards sticky? Forever, or do they dry up and get hard after a time?

Mine are out months and don't dry up. They usually end up getting replaced because they are covered in crickets, etc.

I really varies. I have had mine out for up to 6 months if it stays dry and free of debris. Rain, dust, left in direct sunlight, and leaves for example will shorten the Catchmasters life.

It does not last forever but these lasted 6 -7 months. That's including with dust and dirt!

I have used these type of catchers for years and have never had to replace one because it dried up. More likely is they get full of bugs or the bait no longer attracts anything.

They seem to stay sticky for a long time. I would check every week to be sure. They really work well.

I have had mine longer than that and I don't notice that they are stale or 'bad'. I'm thinking b/c they are freeze-dried, they will last forever.

I have only had them on for about 8(ish) months but they peel off just fine. The walls that they are stuck on was just painted a year and a half ago and when repositioning I haven't seen any damage the walls what so ever. The adhesive is very passive - enough to stick on the wall but not *too* sticky. However, I'd have to get back to you on the "several years" part - maybe someone else will pipe up?

I cleaned my walls and let them dry before I put them on. I also put the extras on the drawers and they hold well. I've had them for about 2 weeks now and there's no sign of peeling off.

Mine seem pretty dry. I'd grind up a test batch and see what you think. If they are sticky let them dry a day or two. Remember you are working with natural materials they vary because nature varies.

Dry place. They come in sealed plastic so they should've perfectly fine till then. I ordered mine early and they were fine. I didn't want to risk them not getting to me in time

I didn't clean them. I have no idea how you would do that and how they would stick after. I bought the larger sheet and cut them in half to make them last longer. One would last 24hrs. Hoping to see some results soon

I've had mine for well over a year and it's still sticky as day 1. I do keep it in a ziploc when not in use, so that might help (plus it keeps it from getting all over everything else in the bag.)

As I understand that you can reuse till they get hard. I've reused mine over 6 months and are still good and there still moist but when they get hard they say to replace. But for the best answer go to there website and check faq.

I have just found a humidipak in a jar i had sealed just hand tight about a year ago and it was just as good as the day i bought them.. but if you leave them out in. Open air they will dry up pretty fast i would really recommend these to keep anything you want fresh and moist. They work great for allpourpuses you need

Unopened, they last a long time and would be good for storage. Opened, they don't. It depends on how humid your climate is, but I'm in a very dry place, and they sog after a few days to a week.

If you took good care of them they will last a year or two. I've used them 20+ times and they are still in their purchased condition. They don't require any adhesive to stay. I wash them with a mild soap and just let them dry. The case they come with helps keep them protected.

I haven't had mine a year, but I'm from the humid SW so I may find the same issues. They should probably be kept in an a/c cool, dry place for starters, to save the self-stick surface. I did find these ear magnets stayed on better than others I purchased.

I put some out in our unheated garage and so far they are still sticky. Haven't seen mice but caught several bugs. LOL

They should not deteriorate if they are kept dry, however avoid moist and dusty environments while storing. Usually I get about 40 work hours in a medium dusty and noxious environment.Hope this helps!

I too initially had problems with them sticking but I found if you apply pressure and heat for several minutes (2-3 minutes) when you put it on it stays much better. When put them on press the palm of your hand on the electrode - that gives it both pressure and warmth and you will probably need to do that each time you put on the electrode. They still don't stick as well as other I've had but these will do until I need them again. Don't use alcohol or anything else on them but you can use a little warm water on them when you reapply them and that might help as well.

packaged they keep for many months, opened about a month or so. if they get dryish just soak them to get them softer.
