Why are there no dead pests underneath my Goodnature trap?
Scavenging is a frequent occurrence so it is unlikely you will see everything that is killed. Rats, stoats, cats, birds including weka, pigs and dogs scavenge dead critters from below Goodnature traps. You can monitor rat levels with Rodent Detector Kits or purchase a Digital Strike Counter to get a clearer picture of trap activity.
What is a Goodnature Digital Strike Counter?
Just in case you were wondering how many times the trap had been triggered, Goodnature has made a digital strike counter. Packed into a tiny enclosure, the strike counter slides onto the CO2 canister and spends most of its day asleep. It is sparked into action only when the trap is set off. Because it sleeps so much, you should get five years between battery changes, even if you check it weekly.
How do I know how much CO2 is left in the canister?
You can test-fire the trap to see if there is CO2remaining. To ensure your traps remain charged change the CO2 canister every 6 months. See our Success Guide for more detail.
How do I refresh the lure?
While our lures are long life, they will eventually tire and diminish in their scent when exposed to air. At least once a month, remove the shroud cap and take the long life lure bottle out, tap it against the tree trunk so the tired lure is dabbed out as a pre-feed to attract pests. Wipe all excess lure away from the bite block, or mouth of the lure bottle, and return to the trap. See the Success Guides for more information.
I suspect my trap is faulty
Test fire your trap as outlined in the Success Guides - your trap may need a new CO2 canister. If you have any concerns get in touch with us!
Can I shift the trap when it is live?
No. You should not shift a live trap. You must de-gas and then de-pressurise the trap before shifting. See the Success Guides for more detail.
Can I purchase extra tree mount brackets?
Yes but best practice is to instead purchase extra traps and increase your area of control allowing your existing traps to manage reinvasion.
I caught a pest! What should I do?
In the field: You don't need to do anything. The dead animal will either be taken by another animal or slowly decay into the environment.
Around the home: A dead animal will get smelly after a few days of warm weather. To avoid any unpleasant odours bury the carcass under a few centimetres of soil or compost.
When can I stop trapping?
To maintain the conservation gains you have achieved through initial trapping, your traps should be left in place for the long term to catch any re-invading pests. Remember to refresh the lure monthly, and replace the CO2 and lure every 6 months.
Do you ship to the United States or Canada?

A24 Rat & Stoat
I already know I have rats. Why should I use the detector cards?
Rodent Detector Cards will show you the best place to put your A24 trap, i.e. places where rats feel safe to eat. Watch our great Rodent Detector video online about how to use these cards to maximise the effectiveness of your trap.
I set my A24 by a compost bin or food source but I'm still seeing rats.
Food-rich areas are complex rat trapping sites and may require extra effort to achieve success. Locations where you see rats or signs of rats are not necessarily spots where they will trigger the trap. Use Rodent Detectors to determine the best place to set a trap. You may have to disrupt the rats' routine by moving or reducing access to the food-rich source, if possible, forcing them to look elsewhere for food.
How do I use the A24 trap to target stoats?
Simply replace your Goodnature rat lure with a bottle of Goodnature stoat lure. Set the trap near the edge of a stream/ waterway, on a ridge, track, or on a pasture margin/bush line. Ensure the trap is set away from houses and other food sources such as chicken coops that can act as a competing food source for the lure. If stoats have been scavenging rats from your A24 trap then now is a good time to target them.
Is the A24 a danger to native birds?
When installed at the recommended 12cm off the ground the A24 is difficult for a bird to enter. The exception is where weka are present. In this case, install the trap 75cm off the ground or attach a Goodnature Weka Excluder to the A24 trap.
Is the A24 trap a danger to pet cats?
Goodnature's long life rodent lure is not attractive to cats. The shroud entrance is also too narrow for a cat to fit its head into, and the trap is installed 12cm off the ground to further prevent a cat interrogating the trap. It is extremely unlikely that a cat will trigger an A24 rat trap. Neighbourhood cats, however, are likely to remove dead rats and mice from below the trap.
How many A24 rat traps should I get for my land area?
The general rule of thumb is two per hectare (spaced 50m apart). If you have a large area for conservation or a complex site such as an orchard, then call us.
Is the A12 trap a danger to cats?
It is extremely unlikely that a cat will trigger an A12 possum trap because the trap can only be fired through deliberate action. A combination of the lure formula and trigger design make the trap unattractive to cats and require the Bite Block to be deliberately bitten and pulled down with 700g of force for the trap to fire.
Is the A12 a danger to native birds?
The lure for the A12 is designed to be unattractive to birds. Always set A12 traps on a trunk that's vertical and at 70cm above ground to ensure no non-target species are put at risk.
My pre-feed is disappearing but I'm not seeing dead possums. Is the trap not working?
The pre-feed may be taken by other animals such as rats and mice. Be patient and re-apply a small amount of pre-feed to the bite block and the tree below the trap. Ensure the trap is set on a tree trunk that's vertical with a diameter between 15-30cm. Set the trap so that its base is 70cm above the ground. Remember, scavenging is a frequent occurrence so it is unlikely you will see everything that is killed.
How many A12 traps should I get for my land area?
The general rule of thumb in conservation is one per hectare (spaced 100m apart). This changes in sites modified and made complex by humans. If you have a large area for conservation or a complex site such as an orchard, then call us.
Oops - I can't separate the tree mount.
If you’ve accidentally snapped the TREE MOUNT and TRAP BODY together before installation, take a flat-nosed screwdriver and ease it between the top of the TREE MOUNT and the TRAP BODY. Gently lever the screwdriver nose down on the tip of the rounded white pressure point. The MOUNT will ease away from the BODY.
I already have an A24 rat and stoat trap. Can I add Chirp to that?
Sure thing. Chirp screws onto your A24 trap just like the original cap. When you buy ‘Chirp for A24’ we bundle it up with an automatic lure pump (with lure for rats) and a gas canister to keep you going.
How do I install Chirp?
It’s easy. Check out the installation guide in our Goodnature Chirp app.
Can I install Chirp on my A12 possum trap?
No. We’ve designed Chirp specifically for our A24 rat and stoat trap.
How do I receive data from Chirp?
When you’re within range of Chirp, you’ll be notified on your smartphone via Bluetooth™ every time your trap kills a pest. Chirp lets you know when the pest was killed, how many strikes are left before you need to replace the gas canister and when to change the lure.
How close to Chirp must I be for Bluetooth™ to work?
It depends on your environment. The Bluetooth™ technology inside Chirp works within a range of 20 - 100 metres. It can be limited by things like physical obstacles or terrain between your smartphone and trap. You’ll get the best connection with Chirp when it’s in your direct line of sight.
How long does Chirp’s battery last?
The battery will last 2 - 5 years depending on your trap’s activity, your environment and temperature.
If I move my trap, how do I update its location?
You can update your trap’s location in our Goodnature Chirp app by clicking on:
My traps > Trap card > Details > Edit Trap > Tap the map and reposition the waypoint > Confirm.
Can other people see where my trap is located?
No. Unless you share your trap with other Goodnature Chirp app users, no one can see your trap’s exact location. However, we will add your trap data to our kill density heat map (see the ‘map’ page of our app) so that you and your conservation community can keep track of how well protected our birds are across New Zealand - without us giving away your trap’s exact location.
How do I share my trap?
You can share your trap by going to My Traps > Trap Card > Trap Details > Manage Users.
Enter their email address and hit ‘share’. They will receive an email to accept your request. If you used the same email address as their Goodnature app login, they can see your trap on their ‘My Traps’ page.

The Goodnature Chirp app is currently available for download in New Zealand only via the App store (iPhone) or Google Play (Android).
Chirp’s red light is flashing. What does this mean?
If the red light is flashing it means Chirp is temporarily updating the data about your trap on your phone. Great news! It means Chirp is working 100%.
Both lights are flashing. What does this mean?
Chirp is smart. Once a day it tests its battery to see much life it has left. During the test some LED lights come on for about 5 seconds. Great news! It means Chirp is working 100%.
I can’t see my trap in my Bluetooth™ Devices list:
Chirp’s Bluetooth™ technology works differently to other common Bluetooth™ devices (e.g. headphones and speakers). You can only connect to Chirp from within the app. See in-app installation instructions to pair.
My smartphone is having trouble pairing with Chirp. Any tips?
There are a few possible reasons for this:
a) Chirp needs to be awake! When you’re on the ‘Pair with Chirp’ page of the app, give Chirp 5 strong shakes. Its red light should start flashing, then you know it’s awake and ready to go.
b) Bluetooth™ needs to be turned on. Check that it’s enabled.
If none of the above tips do the trick, let us know firstname.lastname@example.org so we can help you out.
My kill count hasn’t updated in ages.
There can be a couple of reasons for this:
a) Your trap hasn’t killed any pests recently. Check that your trap has sufficient gas and lure.
b) You haven’t been within range of your trap to collect the data. Get a bit closer!
My battery is low or dead. How do I replace it?
When Chirp’s battery is low or dead, let us know: email@example.com so we can send you a new battery with instructions to help you replace it.
There are chew marks on Chirp. Is this OK?
We’ve designed and made Chirp from hard wearing polycarbonate material with rounded surfaces to avoid it being chewed by animals. If you notice severe chew marks or holes in the cap, we’d love you to let us know: firstname.lastname@example.org.
How do I delete my trap?
At this stage, our app doesn’t support this function. Please contact email@example.com so we can help you out.
My app keeps crashing. What can I do?
Go to the “More” page and hit “Send Feedback” to send us a bug report. In your email to us, please include as much detail as possible so we can help you get it sorted. It’s handy for us to know your phone model, OS Version and what prompted the crashing. Send us some screenshots if you can.An important note for iOS Users: the ‘Send Feedback’ button is only available if you’ve set up your iOS Mail app.
What should I do with my trap's original cap once I’ve installed Chirp?
The original cap is 103ml – the ideal size for measuring things in your shed and the perfect place to store all those 10c pieces you’ve collected. If you have enough collection systems already, you can always fire it back to us so we can turn it into something else to keep pests under control.
Digital Strike Counter
My Counter shows a number, but I haven't seen anything dead.
We get this question a lot. Scavenging is really common – even if you don’t expect it. Pigs, dogs and cats commonly scavenge dead possums.
How long does the battery last?
The battery should last for up to 5 years. The device spends most of its time sleeping as it only uses power when the trap strikes or when you check the tally.
What to do when the battery dies?
When your Counter’s battery dies, send it into Goodnature to be refurbished. NOTE: opening the Counter casing voids the Goodnature warranty.
My Counter still shows '00', why is that?
There could be a number of reasons for this. You could be accidentally zeroing the Counter when you check the tally because you’re holding the button down too long (see ‘CHECKING THE COUNTER’ on Page 9 of our Success Guide).
Other reasons could be that you haven’t followed our tree selection and setup instructions (see Pages 5 and 7) or if you have done, perhaps you haven’t observed our maintenance instructions for keeping the lure refreshed and/or replacing the gas every 6 months (see ‘SHIFTING YOUR TRAPS’ on Page 11 of our Success Guide).
Can a rat or possum set the Counter off any other way?
This is unlikely, as the Counter is calibrated to tick over when there’s a strong jolt such as the trap firing.
How do I put the Counter onto the trap?
See Step 5 of ‘SETTING YOUR TRAPS’ on Page 8 in our Success Guide.
What happens when the Counter gets to 99?
Firstly, you celebrate the success of constant control with your family and friends and then you zero the Counter because it stops counting once it gets to 99.
How many pests can I expect to kill?
Every location will be different. Possum movements and populations vary throughout the year. Provided the trap is properly maintained (see Page 10 of our Success Guide) and located, it will always be ready and waiting as a constant control. You can relocate the trap periodically (see Page 11 of our Success Guide) or grow your trap network to control a greater area.
Why is my Counter showing kills on it when I've got it out of the box?
The Counter is set off by jolts and jolts are something that happen while your Goodnature Counter is making its way from us to you. See Page 8 of a Success Guide on how to zero your Counter.
Will the target pests interact with the Counter?
Yes, sometimes they might. Rats on occasion can gnaw the plastic of the Counter (and the trap) and sometimes possums might work the Counter off the canister while climbing over the trap trying to find how to get to the delicious lure.
How do I get the Counter off the canister?
See the ‘DE-COUPLING’ section on ‘SHIFTING YOUR TRAPS’ on Page 11 in our Success Guide.

Rachel had a Rat Problem
Food competition can be the biggest barrier to trapping success. Things like compost bins, dog biscuit bags, food stores and chicken feed all provide excellent food sources for rats. Once rats have a trusted food source, it can take some effort to get them to try something new.
