Received and set up in 10 minutes. 1st kill 1 1/2 hours later. Very pleased. I had tried Hava heart, rat traps, bucket traps, These guys were not having it. This is a game changer.

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.

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.
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.
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.
3 squirrels in 3 days. Nice cover. Nice looks. Quality cover. Quality A18 unit. Mounts in 1 minute. 2 screws. No more digging up the yard, ruining my bird feeders, chewing on car wiring.
We’ve been using the Grey Squirrel devices for awhile and now these mouse devices. Easy to use!
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 worthless. I have had it for weeks with no kills. I captured 20 squirrels with live traps with the same bait. I see squirrels in my yard every day but still nothing. I got tired of transporting the squirrels away and thought this would be the answer. What a scam.
So far has killed one squirrel and two chipmunks. Took a week for them to investigate, because my bird feeders were full, when the feeders were low they started looking other places and found the trap. I need to check to see if CO2 is spent as there haven’t been any kills this last week. It’s pretty loud when it goes off, but I’m just glad it seems to be a very clean kill. It was set off early a few times before the squirrel stuck its head in by just a paw, worried the noise would keep them away but they came back. My tomato plants have been left alone which makes me happy. Only downers: Wish the CO2 lasted longer or the trap didn’t go off before the head is in.
The squirrels chewed right through the plastic, so they could get to the bait without triggering the trap. The bait that comes with the mouse traps becomes a liquid, sticky mess when it gets warm outside. I have yet to catch a mouse or squirrel with any of these traps. Considering the price, this is extremely disappointing.
Paste that doesn’t leak out to become a free meal would be awesome.
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.
Ive had this about three weeks and have tried two other locations on this tree; there are five trees on my property and probably more than two dozen squirrels. I have used Almond Butter, by itself. I've tried Peanut butter. I have tried mixed nuts. I've spread the butters on the tree on the lower inside of the opening. They smell it and leave. I am being mocked! lol
Before this, I tried many other items to thin out the number of squirrels (they caused $20k damage to solar panels and caught the roof on fire when they bit into the wires). This is easy to mount to a tree and easy to bait. Just remember it's loaded once you add the CO2. This is not a toy!
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!
A little on the expensive side but is far less expensive than fixing the damage these rodents create. Once the squirrel has figured it out, this is the most humane way to get rid of these damaging pests.
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!
10 squirrels in 17 days. Took about 3 or 4 days for them to get confident enough to stick their head in there but it works well.
We have killed 17 squirrels instantly with this device. We did have an issue with leaking CO2 canisters. We resolved this by using plumber tape around the new canisters. Each canister holds a charge a lot longer with the plumber's tape.
Goodnature is the best: A simple trap, most effective. This machine is very kind to the animals. They sleep quickly without pain. My squirrels and rats never know what happened. I spent thousands on devices and poisons before this. For bait I use a variety of natural nut paste - smear it in a line below the machine and on the tree. The squirrel will follow, eating merrily. It is impressive and effective.
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.
Works great. We are using peanut butter it works to attract the squirrels better than the attractant that came with the trap. If you have squirrel problems it will definitely help get rid of them.
"7" count in the first 24 hours! ... Impressed overall with the build and functionality of this unit. The only drawback is that the counter has a malfunction. It arrived with "13" hits on the unit and I thought maybe product testing before shipping. Tried resetting it a few times, per instructions, but it would not return to "0". Maybe taking the battery out and restarting it might help, but I just made a note and "13" became the new "0" for now. Also, glad I bought the metal cover because the footprints all over it shows they were trying to get to the bait station on top. Only a few more pests left. Thanks again for an awesome trap.
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.
So effective! Easy to assemble and install - already had 5 strikes in the first week.
We had two squirrels climbing a tree, getting into our attic, and ruining our important keepsakes. After trying other unsucessful efforts, I was desperate and started researching other options when I came across the A18 device. I immediately ordered it, installed it the day it arrived, and within 36 hours (probably because the following day had a heavy rain all day long), it had taken care of both squirrels. Money well spent! Thank you!!
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.
Major issue with packrats in my community in Santa Fe, NM. The A24 will work and has worked but its size is better for mice. The A18 should be more effective with some testing. The A24 is in use throughout the community as a viable, logical, efficient, and intelligent to the snap traps, other zappers, and the dangerous use of rodenticides in a community that should know better.
