The indoor mouse trap caught two, and the outdoor one caught three just this weekend. We didn’t even have a chance to clear it. Absolutely thrilled with the efficacy.

Frequently asked questions
Does the trap reset itself automatically?
Yes. After every kill, the A24 automatically resets itself using a CO2 canister — no manual resetting required. One canister powers 24 consecutive strikes. Just mount it, connect your CO2, and walk away.
Is it safe around kids and pets?
Yes. The A24 uses no poison or toxic chemicals. The CO2-powered mechanism is fully enclosed, making it difficult for children or pets to access. It's certified humane and designed to be family-safe.
Why aren't there dead rodents under my trap?
This is completely normal. Scavenging animals — raccoons, birds, cats, and even dogs — frequently remove dead rodents from the trap area. Use the Digital Strike Counter to monitor how many times your trap has fired.
How do I know how much CO2 is left?
Test-fire the trap to check if CO2 remains. To stay on top of it, replace the canister every 6 months regardless. The Digital Strike Counter tracks how many shots have been fired so you always know where you stand.
Will it work in extreme temperatures?
Yes. The A24 operates between -4°F (-20°C) and 104°F (40°C). In very cold weather, the paste may freeze — try a local alternative lure. Avoid test-firing in extreme cold as the plastic becomes more sensitive.
Can I return it if it doesn't catch anything?
Yes — we offer a 30-day money back guarantee. Proper placement, pre-baiting, and eliminating food competition are key to success. Check our Success Guides before returning. To start a return, email support@automatictrap.com for an RMA number.

Honestly the best investment i’ve made in order to protect my garage, shed and occasionally my pantry. I live in a semi rural area that seems to have an overpopulation of rodents. The nuisance of single kill snap traps is gone. No more damaged wiring, nests, horrible smells or rodent droppings. So easy to maintain. I have several of these traps around my property and they have likely saved me thousands of dollars from damaged equipment and cleaning. Thankyou
Two down in less than six hours.
Our outdoor trap struck thrice without a clear out this weekend, while our indoor mouse trap struck twice. We’re thrilled with the efficacy.
Oh god how I love this thing! I’ve had multiple kills in the 3w I’ve had it installed. And two nights ago I had my first double-kill! I’d known about the product for about a year but waited to buy because of the cost. But dude, what was I thinking???? This thing is 1000% worth every penny. I’m gonna get 2 more!
Got our first mouse. Our bracket backing broke upon arrival but it still bolted to the wall. Emailed ATC and the sent a new bracket without question. Great customer service. Amazing mouse trap. The design and finish is pretty, the bait station is big, the power is insane, just an impressive product all the way around. Stoked to get a few more of these.
I've dispatched 5 or six mice already since September 10th with the A24.
This tiny mouse trap came with the larger rat trap as a bundle. I almost didn’t set it up, as I thought it wouldn’t work. I was way wrong. We’ve had 5 mice taken out in as many days. I’ve ordered a 2nd unit for under our motorhome. I’m considering ordering a Bluetooth booster to see if we can receive notifications from inside our house. Currently we must walk closer to the trap in order to get a notification.
Works perfectly! Getting rid of crawlspace nesting issue!
Can’t really say how great it works as of yet as it’s only recently been placed. Love the design and see no reason why it shouldn’t work as advertised. Love the connectivity feature through the app to monitor it.
This thing is well worth the money to me! Automatically resets itself and that means I’m trapping even when I’m away on vacation! Love it!
Got the sucker the same night I set it up.
It works! Just need to find the right bait! I used crumbled cheese instead of the included chocolate bait. Placed it out last night and this morning we woke up to two dead rats. I ordered another trap for the back porch today! Very pleased after switching baits!
I'm a truck driver, gone most of the week, and don't have time to mess with snap traps. Mice started showing up in the garage and house, and the usual traps were just a hassle. Picked up this smart mouse trap and set it up in the garage. Real easy. Since then, I haven't had to touch it much. It resets itself, and lets me know when it's time to clear. Not the cheapest, but definitely worth it. If you're not home much or just sick of babysitting traps, this thing's worth a look.
This is one cool trap! Got it as a novelty � the piston is loud when it goes off! How cool is this thing!
I suspected I had a mouse problem in my kitchen cabinet, but didn't want to use poisons or a snap trap due to previous bad experience. This trap was very easy to setup, it took two nights to get rid of the mouse and the app on my phone notified me that it had a kill. You just twist and pull the trap apart to separate the carcass compartment which I then just tipped into the trash bin. Very easy! And now I've set the trap up again to protect the area since the battery lasts long.
Best trap ever! Worked day one, 1-2-3 just like that. Taking my home back, buying one more for extra duty.
It works. Probably have about 30+ kills so far.
Works great. This is my second A24. Had the first one for a few years. I recommend for the regular home owner.
Worked! Had it set up for approx 1 month. Had its first kill. The app alerted me.
Expensive Trap! But Works Great! In the first 3 days of operation it has already dispatched 18 mice! Clearing the trap is an easy task for my wife and daughter, who otherwise despise removing mice from standard mousetraps. The A24 trap is completely automatic � all we have to do is toss dead mice over a fence for the magpies and crows to clean up. The app has a kill counter that gives us the date and time of each kill.
Best dam trap ever!! Got a rat problem? Put this trap outside and your rat problem is solved. I got 5 in one night.
Effective. Brilliant idea, easy to deal with and robust. Worth the money because it's effective, humane and re-sets for multiple catch. Good job.
Dinner Bell. It's fast and humane. The bang that it makes is like ringing the dinner bell for the cats. Works great but you need the counter to know it's working.
I really like the quality of structure and the way it operates. I’ve had it in play for about a week. I’ve not caught anything yet and have been moving it around. Still working on finding the proper location. I have high hopes it will actually provide the results I’m looking for. May need to use the lure scent better. We shall see.
This morning I heard the trap sound just after 900am Monday. , May 25. I checked the app & saw the Kill word! I double checked & saw there were 2 strikes! Just have to be patient.
Set up and deployed to known areas of presence in a shed, but no strikes in a weeks time. Maybe the rodents around here do not get enticed by the chocolate paste bait supplied with the A24. There were no alternative baiting methods supplied with rat and mouse home trapping kit.
It has worked well. Love the notifications to empty trap.
Just unboxed and set the trap up this afternoon-placed it on my patio where I have observed pack rats over the past couple of weeks, hopefully they will check out the trap
This trap is great. Super convenient no longer having to go into the basement to check to see if I caught anything. The only slight issue is that it doesn't seem to kill all mice right away. I've caught 6 mice in the two weeks that I've had it and 2 of them have survived enough to walk away from the trap and just sit there. It is very easy to recatch them at this point as I imagine they are pretty messed up, but they do fight before I kill them. It seems to work fine on the smaller mice, but its unfortunate that larger mice have to suffer until I can get down there.
Problems with shipping, unable to fulfill the smart mouse traps. Squirrel trap is fantastic
Great device, well made, worked on the first day. I'm averaging 2 - 4 mice per day since install. Works great, easy to use.
I've had 3 strikes so far, but they have missed each time. Not sure what to do about that. IT makes such a big bang, I'm sure other rats will not go close to it now. Any suggestions?
The black cap arrived cracked.
Just getting started
The trap does not work at all. I put it next to mice or rat activity; they ignore it completely. Standing there for weeks, not one catch.
I've had it 4 weeks and not one rat has been killed
Seems cool. I’ve put it out for about a week, two different locations (where rat poop is) and nothing yet. I’ve tried peanuts, cheese puffs, and dried squid.
! week. Lots of activity( crawling on it, sniffing the bait pod, etc around the trap . No kills yet.
After a week in a garage in a wooded area, no mice have been caught. I know that there are mice in the garage, so perhaps I haven't set up the trap correctly.
