Good for catching a mouse that is running for cover; otherwise, a bit.messy because it requires action to take the mouse out of its misery.

I'm used to using skunk/squirrel traps like this and I wanted to try out the smaller version to place in front of a hole that may have had a rat in it. This trap came coated with a green rubber type coating which I think was fine. The trap works similar to the larger one and I did catch a larger squirrel in it - it didn't have much room to move around once caught so I had to get it out in a hurry or it would have a heart attack....I think the larger trap is more versatile - it will catch both large and small critters. This trap was fine for a smaller version if that is what you're looking for.

This is a great trap to catch mice. We had over 20 of them in the garage and every morning this trap had 3 plus in it. I put a small cracker with peanut butter in it. It worked like a charm. It's also easy to open when it's time to release them.

I have a mouse problem in my wife's car.  I am worried about the possible damage from the mouse chewing on the insulated wires and about the possible disease carried by the mouse.  I ordered these traps, and after free shipping with Amazon Prime, I got them two days later.  That was yesterday.  After following the directions exactly, I checked the traps 2 hours later.  Behold, I had caught the thing.  I let my kids and their friends look at it (still alive) before I let it go.  Another two hours went by, and I checked the traps again just in case.  Uh-oh!  There was another mouse.  How many mice are in my car?  Well, now it is the next morning, and I have caught three mice so far.  I keep one of the traps next to the tire of my car so that I can be sure that the mice I am catching are indeed from inside my car.  This trap has not caught any yet.  I find it hard to believe that a mouse would bypass this easy to reach food to get the much harder to reach hidden food in the back of my wife's car.  I have been using these traps exactly how the instructions say to, and they are working great.

The Bad:
As the box states, these traps do not allow a lot of air into the box.  The mouse could "expire" before you get to it.  The mouse will also poop and pee all over itself.  Kind of nasty.  Check the traps often to minimize the mess.

What I like about these traps is that I can hear them shut when mouse is caught. I can take them outside and to the forest right away to reduce the stress on the mouse. Even if I don't hear them shut, I still check them regularly in case a mouse is caught inside. They are easy to use. You place some peanut butter on a soda cracker and slide it into the slot on one end. Then you place the plastic covering on. On the other end you press down on the trap door and secure it under the catch inside. You'll need to press down on the plate that springs the trap shut in order to hook the door. The trap shuts by feeling the weight of the mouse on the plate as it goes to smell the peanut butter. I have caught little mice so it doesn't need much weight at all to work. I also run them under water if a mouse leaves droppings. Usually they don't leave droppings because I get them outside so quickly. These traps have worked really well for me once I figured out where to put them. That is the trick is to figure out where the mice normally travel and put one there. Having multiple traps has worked best for me. Also I don't wait for them to chew through the cracker when I remove the plastic cracker covering. They are too upset to eat and would just rather be free I think. I lift the cover, then the cracker and they look at me and run away into the forest. I did have a small mouse squeeze out before I could get the cracker out but none of the mice are interested in coming into contact with me. They look around when the trap is opened and usually take a few seconds to run away.

After trying many other prodcts found one which works, it is catching many mouses from my home. I am giving four stars because it is too small in size, I had to tie them to something in order to avoid large mouses move them away.. Please make little bigger one

They do work. I caught two mice using these. You can clean them up and use again easily.

They don't snap as hard as some others, so one of my catches wasn't a quick end for the little guy. It wasn't pretty.

I was trying Peanut Butter in the end of a Paper Towel roll trick for 2 nights in a row. I set up my motion detecting camera and everything. No mice.

I put this little trap out for 30 minutes with a big piece of sticky cheese and BAM! caught!

One thing to keep in mind - there is a slot for the bait to go, if you are using PB to catch a mouse, make sure that you put the PB in between the two pieces of plastic (there are holes for the smell to attract the mice). But mice can choke on PB if they eat too much.

I released our intruder into a large field about 6 blocks away from my place.

It caught my mouse! It was a very cute mouse and I didn't want to kill it. It took about a month for the mouse to get caught in this even though I saw him on my counters walking around it every day, but it went in this thing over the kill-trap (which I put out because I was skeptical of its effectiveness after a few weeks) so it's gotta be pretty decent.

We have been using these for a while. They certainly work, and we will continue to use for interior traps.  Keeps the food away from out dog an minimizes mess/cleanup. However.... I don't think they work well for smaller mice. I have noticed that sometimes the bait is nibbled on but the trap not triggered.

To be fair, we have also caught a lot of mice with these

We received a set of six with a key to open the secure bait stations. I've got wildlife in the yard that I do not want to get mixed up in the stations. Upon arrival, I can confirm that there is no way anything larger than a mouse will be able to access these. The opening is small, but then the mouse has to walk thru a tiny mouse-sized chamber to get to where the bait is located. I feel fairly confident that even wildlife with thumbs (say, a raccoon or toddler) will not be able to break in, due to the locking mechanism requiring a key.  I would not say that they are entirely weathwrproof; for example, if you got 1.5 inches of standing water, yes, your bait would get wet. But, I wanted these for dry locations like garage, shed, etc. I do not know whether there are even mice (new location) , but this product absolutely fits the bill for what I was looking to purchase. Whether mice die is now entirely up to the actual bait I placed in the station.

I have been trying to catch a mouse for a few weeks. Used glue traps and other snap traps. Somehow the mouse kept eating the bait and escaping until today. Set the traps in the afternoon and caught it by the evening. Bait holder forces the mouse to climb on trigger lever

A little hit or miss.  We set up two traps, both were triggered, but only one had a catch.  They are a bit hard to set because they work like a teeter totter, when they are tipped forward, the door stays open, when they are tipped back, the door closes. You cannot tell if you actually caught a mouse  unless you pick up the trap. I think a translucent trap would be easier to check for a catch.  The door is held on by only a small peg and a hole, which I think was too loose on one of the traps and the mouse was able to get out. I think a spring loaded door would probably work better. The mouse we did catch was in good condition and we released him in the woods. The inside of the trap was quite dirty from the mouse. Rinsing it out with very hot water worked great.

it caught a mice but the mice rolled over and the flap flopped down and it was able to escape.  i think you need something to hold it on both sides to prevent the mice from escaping

within 24 hours of baiting these traps with peanut butter on a little piece of cereal I caught a mouse in my kitchen, and a mouse and a vole in the crawl space.  Set them up with the bait facing the wall (mice like to run along walls) in places where you find mouse droppings and you will catch and kill a pest.  They're very easy to set, sturdy, and kill the rodent very quickly. I actually heard the one in the kitchen go off and the mouse was dead by the time I got there to check on it, so these are far more humane than poison or those glue traps.

Works really well at trapping (with bait). doesnt work well at KEEPING mice/shrews etc. trapped.

I have a country home deep in the woods, and mice inevitably manage
to find their way in once in a while.  I've had good luck putting these out
at the first signs of a mouse, and catching the little guy (or gal) within
24/48 hours.  I use a few together around the areas of any evidence
(droppings, chewings).  Setting them up is super easy, as is letting
the mouse free a good distance from the house.

A nice point of these is that the smoked plastic seems to help the trapped
mice panic less.  Mice don't have great eyesight, so with the shading
I found they didn't panic as I picked the traps up and drove them to the
other end of my property before setting them free.  (Indeed, one little
one just kept eating his peanut butter and cracker the whole time).

The one negative point that has been raised before is that these are small traps
without air-holes.  So if you're not in a position to check them a couple
of times a day, you might be better off with a larger/different solution.
And you certainly don't want to leave them more than 24 hours, or you
are risking causing the mice a painful death.

You can of course drill air holes, although that seems like a lot of effort
for a cheap plastic product when there are other choices.

But for my set up, where I'm around a lot of the time when I'm here
in the country, they worked great.
