How long do these last? I've had mine for maybe 3 years and it seems like the mice droppings are back or I've got spots in front of my eyes.

Sorry I can't help....I couldn't use mine, it drove my dog crazy so I had to unplug.

I've only had mine for a year, but I only had 2 mice this past winter as opposed to previous winters where I caught 20-30.

I've have 5 of them in various parts of our sprawling house. Four the them are over 10 years old and still working.

I had that happen when i first started. They probably will even out. How long have you took them??

They can last up to two years, if taken proper care of, and if you're super clean with handling them. If there's any foreign bacteria that the little critters don't know how to handle, they could easily die shortly after that, unless you take extreme measures to clean the whole thing.

I have had this unit for 3 years. I had been repaired once already. I currently do not see any white spots.

Good question. I have no idea. No mice for at least a couple of weeks. We wouldn't be able to tell it's broken until its light stopped flashing or the mice reappeared.

For mice I used about a tablespoon and applied about once a week or after a rain. For voles you might try more or more often.

Well, it did not happen with me. The mice vanished when I plugged the units in the wall socket. That was four months ago, and they never came back despite the ferocious winter. I find these devices to be excellent. Our home has wooden floors, vaulted ceiling, ceiling is wood. The ultra sounds bounce all over the place.

They're good for about three years. They only last about a week so that's plenty of time.

My very first mouse, a ball mouse, lasted for five years. My second mouse, a motion type, lasted for seven years. I'm not sure what makes a mouse last or not last, to be honest.

If you take care of them they'll last forever. I clean them with a soft toothbrush after I use it and keep it in the case they give you.

I have not had a problem with my mouse. I would try putting in fresh batteries.

Yes! I bought these about 10 months ago in Nov. 2013 and plugged them up on counters as well as near the floors in pantry. Last year where mice and problems were everywhere, now are empty mice traps and no mouse problems! They definitely work!

I've gone through 3 of these keyboards. The keys and the springy part under the keys are plastic, not metal. This makes them wear out over time. I do A LOT of typing, so it stands to reason they'd wear out faster with me. If you do only moderate typing, it should last you at least a couple of years. All 3 of mine lasted a little over a year.I've never had the mouse die on me. I've given them away as I replaced the keyboard. The M510 mouse is awesome, and I can't stand any other mouse! It's spoiled me. Feels good in your hand, not too big/small, good range for receiver, can be used by righty or lefty, LASTS FOREVER!

Ours weren't bad, but you might need to rinse them. I know after about 6 months ours were pretty dirty and I just used soapy water and then rinsed them in clean water and they looked great again.

I have not replaced the batteries yet, so more than 5 months so far. Hope this helps, as they didn't seem to abate the mole/vole situation?

I have found the batteries to last about 6 -8 weeks with cheap batteries. It also depends on how many mice you kill at a time. I caught 20-30 mice I'm that first set of batteries. My second set has been in more than 2 months but less mice now. Maybe 5-10 mice this time. As far as cold weather I don't know yet. It hasn't gotten cold yet. Also the mice do stink if left in the tray for very long. Especially if it's warm weather. But in child weather I would think the opposite. I am very very happy with my trap. I am sure with high quality batteries You could get 5-6 months.
