Got questions?
Yes. After every kill the A18 automatically resets itself using a CO2 canister — no manual resetting required. One canister powers 18 consecutive strikes. The dead squirrel drops out automatically as the trap resets, ready for the next one.
Yes. The A18 uses no poison or toxic chemicals — it's 100% toxin-free. The CO2-powered mechanism is fully enclosed. It's safe to deploy in areas with livestock, dogs, cats, and wildlife with no risk of secondary poisoning.
This is completely normal. Scavenging animals — foxes, hawks, raccoons, and other wildlife — frequently remove dead squirrels from the trap area. Since the trap is toxin-free, scavenged squirrels pose no risk to predators. Use the Digital Strike Counter to confirm your trap is firing.
Squirrels are attracted to nuts, corn, seeds, and peanut butter. Start with whatever is locally abundant in your area as squirrels are more likely to investigate familiar food sources. You can also use Goodnature's toxin-free paste pumps for a tried and tested solution that lasts up to 6 months.
Yes. The A18 is designed for squirrels and large rodents including mongooses. Its larger entry point and more powerful CO2 strike make it suitable for any rodent larger than a rat. Always check your local laws and regulations before trapping — some species may be protected in your area.

Wow! Couldn’t have worked better! Prebaited for a couple of days to get them comfortable. Within a few hours of final setup got two, one literally climbed on top of the other. Got several more to deal with but on the right trajectory. Dale, you have invented a fantastic solution to the problem.
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.
8 down in two weeks. Need to rebait and potentially move from time to time I think but largely great product.
Works great!
Have had it up for about 2 weeks now hits yet tested works fine wrong bait for red squirrels trying crunchy peanut butter now your bait produced no results they just look at it 6” away like their laughing at saying that ain’t going to get me no results yet still hoping maybe do you have a better bait for orange red squirrels
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!
After spending nearly $1000 on ground squirrel traps and pest control people, the Terratrap solved our problem almost instantly. I followed the directions to a tee, and within one week the kill counter was at 20, scavengers (I think skunks based on the smell) took away the dead bodies and I was able to fill the ground squirrel burrows. If you have a ground squirrel issue and natural predators/scavengers, this trap is a no brainer.
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.
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!
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.
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.
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.
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!!
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.
We have squirrels that have been borrowing into our soffits. We patch the soffits and the dig another hole. I got 3 of them in 2 weeks. Excellent
This AR-18 is incredible!! I have tried countless ways to reduce the squirrel population due to the damage they do to our house and outdoor furniture--pellet gun, live traps, and various traps--all with limited or no success. With the AR-18 I got 5 squirrels in the first six days. I am thrilled! I highly recommend this device.
I received the A18 promptly and setup was easy and straight forward. I had a bothersome squirrel chewing on my house and deck and deck furniture. It took about 10 days for this squirrel to use the trap. The squirrel had a nest in the tree that I attached the A18. I first used a mix of nuts and almond butter, but the squirrel was just curious. I then tried shelled walnut pieces that were large. I put a few around the tree and on top of the A18. The next day there were two expired squirrels on the ground. The total expired squirrels is now up to ten (10). There was one squirrel that didn't expire from the punch of the A18, so I had to finish the job. I don't know what happened, but it didn't suffer long. So far I am very impressed with the quality of manufacture and the functionality. My house, deck and deck furniture are no longer being chewed on. For now... HFB
I appreciate the technical aspects of the trap. However, after trying several different bait types, and having the trap in the field for more than a week, I have yet to trap a single squirrel.
2 days out in my Oak tree and I got a squirrel and three mice. Works right away.
Answer to my prayers! It worked day one and 2 fat grey squirrels are no longer getting free rent under my house. It’s also so nice to not have to remove them from a trap. I thank you, and my neighborly coyotes and turkey vultures thank you!
Well designed, except the the soft plastic. I ended up buying the metal cover for it after reading reports of squirrels chewing the caps. The squirrels that I'm after are chewing up my poly furniture, so I figured that they would chew the trap up as well. It took three days before getting the first squirrel, but another week has gone by without a strike. I probably need to freshen up the bait or move it to another part of the yard. I'm satisfied that this will eventually reduce the poly-chewing population.
The A18 Squirrel Trap is a well made product that installs easily.
Just one squirrel dispatched so far but he/she was my primary offender….littering the ground with heavy unopened pine cones landing like atomic bombs from a 50ft pine tree, partially gnawed for sap & seeds & looking like macerated cobs of corn! Just obnoxious littering and actually dangerous if they hit you on the way down or are thrown out of a riding mower at high velocity! Don’t have to worry about him/her anymore & I was alerted to the kill by the sudden appearance of 2 vultures, lured by the smell of a day old body in the TX heat. Outstanding hassle-free mechanism & only a few other squirrels roaming at a much greater distance, but it will stay up & ready for action…I love it!
We followed the instructions and we had 5 kills and then they just stopped going into the trap. I re-baited it and took out the trap. They ate the peanuts but once I put the trap back inast week, there still hasn’t been any kills in the past few days. Seems like they figured out that it would take them out. Hoping that they start going for it again. Seems like a lot of money to only kill 5 squirrels before the figure out it is a trap.
Not sure how you can improve the device. I've had it for a month and have had no bites. Yet I've seen ground squirrels around the yard. I've checked the counter and it hasn't changed. The tree I have it mounted on has several dozen holes in the ground. The A24 is a different story. I've caught several rats so far.
Already got 4 of the bastards. Nothing else has worked. Getting ready to move it to another part of the property.
It's good, was going to move It's location and presto. Nailed two squirrels in two hours.
Our squirrels must be smarter than average. Put peanut butter in the bait holder and no interest. Put a cardboard shroud over it to peek their curiosity, and it got their interest but none went into the chamber of death. The instructions mention some kind of attractant included, but not in the box. Still holding out for success. Thanks for following up
We nailed our problem in 2 days! WORTH IT!
Trap does its job
I got a squirrel on the first day and next day heard it pop and saw a squirrel running away. One more pop in the middle of the night but no kill. I’m using nuts and peanut butter for bait. Should I be using something else? I certainly have no shortage of squirrels in my yard. I have counted as many as 25 at one time digging for food. Thanks for any suggestions.
Waiting on the squirrels then I will no how good it works
I don't think this works. After about a week, I have three strikes by the counter but no dead bodies. Do they crawl off and die?
Caught a big rat the first night - very encouraging. I patiently waited for squirrels to take the bait, but after a week - nothing. So I opened it up and discovered that all my peanuts were eaten! A tip for newbies - if you leave even the smallest crack between the rock and the base, mice will get in and eat all the peanuts. Also, mice can get the peanut near the trigger without triggering the trap - so check it often to ensure that the peanut is still there. After re-baiting, I caught two squirrels, much to the delight of the local ravens. I'm on another dry spell, so time to either move it or rebait it. There are still plenty of squirrels eating all my fruit and destroying my concrete slab - so hopefully this very expensive trap will send them to squirrel heaven soon.
IT WORKS AS ADVERTISED!
