This best defense is to cut the mice off! This did it!

We moved into an old family home where it was hoarded with years of collected books, records and old everything else. The 90 year old lady let us in to clean we discovered mice feces throughout. We cleaned and did a total renovation. Within one year and our first fall within, mice sounding off their presence overhead and in the attic. A friend told me about this product. Then told me about the uncanny abilities that mice had to accomplish entry.  I check on-line for all the places mice could enter and was overwhelmed with the amount of work that would be before me. There we holes and gaps along each edge of the house. This house is without basement. The siding on the home is nor more that two feet from the ground (below that is brick); and ivy allowed the mice to just climb up the overgrown vines like scaffolds. Furthermore I learned that mice can also climb brick. After removing the ivy, this product was filled in every gap snug and without waste. I was able to cut each piece to size it whether to fill a long gap or a small and/or deep hole. I found evidence that the mice discovered the wall that was made to keep them out. And I was so happy to know that it worked! Absolutely the right way to go; this made it easy! It is worth every penny. Home Depot sales it but does not seem to carry it in the store. Amazon had the best deal as I received a combo of 3 rolls. The most meticulous work was locating every possible entry point. Note: Use a magnifying glass or mirror. You must see from a mouses point of view! The snow has come. The job is done. The sound is of silence over my head.

Great trap! So nice to be able to "relocate" our visiting mouse instead of killing him/her.  Worked like a charm!  We used peanut butter and placed trap in kitchen drawer where we had seen mouse droppings.

We got an unwanted visitor in the kitchen. I didn't want to kill him with the brutal stuff like glue traps. That is the most horrendous thing I can imagine. So I got 5 of these Mice Cubes. I set a them with peanut butter and a cracker, put the scent of PB on the doors, placed them around the kitchen at 7pm. We went out for dinner, back by 8pm, open the kitchen drawer where he had been hanging out and there he is, in the Mice Cube. A tiny little mouse. Amazing. Took him down to the local soccer field where he can live in the forest blocks away from the nearest human dwelling and set him free in the bushes.

Mice Cubes are the Oskar Schindlers of rodent prevention. They will save thousands of lives, I can't recommend them enough. Relocate the critters and don't use killing traps... there is enough suffering in this world. Just don't forget to check the traps, you WILL catch your mouse and so must remember to get him out before he dies in there.

This this is extremely effective. We have a small group of mice that have infested our stove. I opened this trap today, put some D batteries in, put a large slab of peanut butter way on the back wall, shut off the lights to go to bed and it caught and killed 3 mice in the last hour. They died instantly and we disposed of them by simply tilted the trap down and they slid into our trash chute, no mess or anything. This works very well.

My son and I lived at my Mom's last year while my husband was deployed.  She has a split level and I was living in the basement.  The movers had lost our bed frame so my mattress and boxframe were on the floor (do you see where this is going??)

So I was reading a book one night before going to sleep and a mouse CLIMED IN TO THE BED WITH ME!!!  I was soooooooo totally grossed out!!  Needless to say I went out and bought a bed and frame the next morning... after I slept upstairs on the couch!!  There was a huge nest of them in the closed-front fireplace.  I tried the standard *SNAP* traps (I got 5 the 1st day.... bleeeeeechhh!) but I had to stop that after the last time (there were TWO in the trap) they were still alive, bloody and flopping...... eeeeeeewwwwwww[...]

I went to lowes and bought one of these traps.  I LOVED THIS TRAP!! The mice are D-E-A-D, DEAD!  You just take the trap out to the trash can, flip the top, and dump out the dead-as-a-doornail corpse.  No more mice that aren't quite dead.  No more snapping your fingers in traps.  No more having mice steal the bait and yet eluding the trap.  And you don't have to worry about your pets getting hurt or poisoned.

I'd give it 10 Stars if I could!!

We began to notice mouse droppings in the kitchen so in an effort to rid the house of mice humanely, I bought one of these.  I put a bit of cheddar and mozzarella cheese in here and we went to bed.  About ten minutes later, we heard a snap and a little rustling.  Came out and saw we caught our first mouse!  I released it far away from our house and set it up again.  The next morning, we had another mouse! We ended up catching one more the next night and haven't had any more since, so I think that's the end of it.

Pros: Works well, without killing
Cons: Somewhat of a pain to clean, with lot of areas the waste left behind can get caught

This product works! The caveat is that rodents who already made their home in your dwelling are unlikely to move as a result of this product because they WILL MANAGE THE PAIN in order to continue their shelter, food, and water. HOWEVER, if you destroy these rodents (rats, mice) via snap traps FIRST! this product will act as a deterrent against ANY FUTURE rodent infestation as they will not venture near this product! This is exactly what happened to me as a result of my own experiment and research. Installing this did nothing to my current rat infestation, however, after snap trapping them, I have been RODENT FREE EVER SINCE. I know because without this product, I will catch a rat every other day, up to 3 rats per week, almost 12 a month! But with this product, there were ZERO rats after the initial trap. With this product however, the rats have stayed clear due to this ultrasonic frequency and I have not seen them since.

Wow! This trap is incredibly effective! So far, we have owned it for only four nights and we have caught four critters: one lizard (that we set free) and three pesky Norway rats that have been living near our chicken coop.  We will order a couple more of these traps because they work so well and you don't have to kill any innocent (and welcome) birds or lizards. The traditional rat traps that we were using before were often "tripped" and knocked over but empty. This device is far more effective and worth every penny!

I certainly applaud this product.  This is for softies like me who don't want mice invading our living quarters, but feel the critter has the right to live and prefer releasing him out in the wild rather than killing him.  Highly recommended.

I just got this in the mail today.  Last week, I bought some glue traps and on the back of the glue traps there was a diagram showing how to place the glue board into this trap.  I have a mouse problem!  I have tried being nice using all kinds of nice ways to spare their little lives but they paid me back by inviting all of their friends to party in my house and have mouse babies.  I have some good snap traps and I have glue traps and I have some of those smoky plastic humans traps but all of them had one problem  - my dogs would try to steal the traps to get the peanuts or peanut butter.  Trying to unstick a small dog from a glue trap is no fun.  They tore apart the smoky plastic traps and I found most of the snap traps in the back yard.  This trap here is perfect!  There is no way my dogs will be able to open them and get the treats or mice out of them.  This means I can finally set traps on the floor near the baseboards and other places where I normally haven't been able to set traps.  I bought two of these and I think I will be able to use them for years.

Just a couple of days ago, I was looking through some old boxes in my garage, and noticed something hopped out of one and darted away.

"Great. I've got a mouse to deal with." I thought.

Without thinking too much about it, I mentioned (read: warned) my wife that there might be a mouse in the garage.

"Don't you remember when I said it looked like mice had eaten all of those peanut butter bird feeders I made, and kept in the garage?" In truth, I did remember this, but figured the unseasonably warm autumn had melted the peanut butter, or that it had otherwise mysteriously disappeared from my historically mouse-free garage.

The next day, a scream filled my living room. My idiot dog brought in a freshly killed mouse for us all to enjoy.

"Great. Now I've got many mice to deal with."

I went straight to the home improvement store. Not even Amazon Prime could bring justice fast enough. If there was a mouse-catching robot, I probably would have bought it. My objectives were:
1) Must be safe enough to not snap my toddler or idiot dogs.
2) Must not be a poison that would potentially leave mouse carcasses in old boxes.
3) Must not terrify my wife and / or daughter upon "use".

But apparently, these traps are the most advanced ones the store carried, next to some dopey ultrasonic thing that would most likely send the mice in to my house or shed if it worked well enough to annoy them out of my garage.

Since peanut butter brought 'em, I figured peanut butter would bait 'em. And just hours later, my theory was proven correct. I was a bit concerned about the traps being potentially inhumane after reading many of the reviews, but to date, the mice have not complained.

It works great! I even caught a few mice with it without using bait! The blades seem powerful enough to kill mice and there curiosity makes them go in!

We had two mice and caught them both. I tried a few diy traps and then bought a cheap humane trap that the mice broke. This is sturdy and gets the job done.

If Blofeld or Goldfinger made a mousetrap, this could be what they'd come up with.  A Bond-level villain's death-trap!

This trap is:

Easy to bait
Easy to set
Easy to place
Easy to check if the mouse is caught
Easy to dispose
It's even easy to open the blister pack package!

This is a clever design.  There's a bait door in the back of the trap that pops open.  It has a little container to hold the peanut butter (the recommended bait).  Slip in a little PB, close the door.  Now there's no access to the bait except via the entrance.  Then press the red lever.  That sets the trapping device.  It's VERY sensitive.  You might have to press the lever down a few times as the catch BARELY holds the trapping device in place.  Set the trap in a mousey place and that's that.  When the mouse is caught you'll know by the position of the lever (very obvious).

The only problem is ... will it actually attract a mouse?  I had a clever little mouse invader who successfully ate the bait (peanut butter coated raisin) from a regular trap 2 nights in a row.  The 3rd night I put the Ortho near that trap.  A couple of days later the bait was snatched from the regular trap again while the Ortho was undisturbed.  I reset the regular trap and swapped it's place with the Ortho.  The next day the mouse's luck had run out.  But it was killed by the regular trap.

So I don't know that enough peanut butter smell escapes the Ortho to actually attract mice.  It looks like it SHOULD work.  But I can't guarantee it and I don't have enough of a mouse problem (1 or 2 a year) to test it quickly.

I estimate that the Ortho is an effective and clean mouse killer and would be useful in situations where you have a low level of mouse activity.  If you had a lot of mice it could be expensive to keep buying the Orthos.  Note that if the mouse leaves or is killed some other way it's easy to pop open the bait door, clean the old bait out and wait until you need the Ortho again.

Finally, cats dogs and children won't be hurt by this.

Also, I've noticed some other reviews saying the spring isn't strong enough and the mice aren't killed instantly.  This is a ONE USE trap.  If you reuse it the spring gets weaker and won't kill reliably.

No one paid me for writing this but this device worked so well. It killed one mice after the first 24 hours. I plugged in 2 devices in my basement/gym/storage (total 500 sq ft). Now I plugged in 2 more in the garage area 300 sq ft. Love it!

My house was overrun by mice. I used ever gadget out there to get rid of them. I ordered four or five of these. In as little as 2 weeks it had rid me of 25+ mice. I was absolutely ecstatic. The mouse goes in the little hole and it is electrocuted. You do not have to look it. You just take it out and dump it. I must admit the thought of the whole thing is gruesome but I would rather be rid of the mice than deal with who knows what disease. Mice are adorable but they are delightful disease riddled demons. I highly recommend this product.

Traps mice every time.  Warning: mice will jump around and make this thing move across the floor!  Secure it somehow!
