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, foxes, birds of preys and dogs scavenge dead pests 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 COcanister 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 COremaining. To ensure your traps remain charged change the COcanister every 6 months. See the Success Guides for more detail.

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.

How do I refresh the lure?

While our lures are long life, they will eventually tire and diminish in 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!

I caught a pest! What should I do?

In the field: You don’t need to do anything. The rodent will either be taken by a predator such as a badger, buzzard, cat, fox or owl; 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 COand lure every 6 months.

Goodnature A24 Trap Placement – Location


The key to having consistent, successful results is location & placement, before you even use the trap;  clear up competing food sources in your area. Pre-bait the site with the chocolate formula and use the detector cards. Rats communicate through their breath and whiskers, if a good head of rats in your area feel safe to feed on the chocolate gel, they will pass this on and actively seek out the food. Look to place the traps nearer where the rats are living, in a safe place out of sight of avian and ground predators. Don’t be tempted to put it where you saw one running down the side of a building, this is not a feeding spot. They will not have the confidence to stop and feed here.

Once they have taken all the free offerings, set the trap in an area that is away from disturbance; place in a box or under shelter at a 45′ angle as this will help hugely! The detector cards will tell you if they feel safe to feed there.

It will take a few days for the rats to overcome their initial fear of it, then you should start seeing results. Don’t be afraid to continue offering freebies of the chocolate formula, this will help vastly! Check out our easy lure pouches, they are perfect for the job. The big thing with our traps is finding where the rats will interact comfortably, you may feel like you’re having a slow start, trust us when we say that the more time you put in getting it right initially; the less time you will put in later.

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 in an area you believe you have stoats. Use natural cover to shelter the trap, stoats will feel safer to feed and interact. 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 trap a danger to pet cats?

Goodnature’s long life rodent formula 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 12 inches 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 from below the trap. You may also purchase an extender tunnel to add a third layer of security.

How many A24 rat traps should I get for my land area?

The general rule of thumb is two per acre (spaced 40m apart). If you have a large area for conservation or a complex site such as an orchard, then please call us.



Ensure you install the traps as instructed

For best results, and to ensure a humane kill the traps must be set as instructed. See our Success Guides for details.

Refresh the chocolate formula monthly.

To direct pest activity to your trap site refresh the lure in your traps regularly and prefeed them with a little of the rodent lure. This should be done at least once a month. Every week is even better! See our Success Guides for details.

Replace CO2 every 6 months

To ensure your traps remain charged, replace the CO2 every 6 months. A good way to remember this is to time it with the replacement of your smoke alarm batteries at daylight savings, every 6 months.

Add to your trapping network

The principle in the field is to ensure that every pest is put at risk by a trap, and that the risk is greater than the rate of reproduction and immigration. Rather than shifting your traps, add to your trapping network. Goodnature A24 traps for rats can be set 40m apart.

How many traps to use

In a conservation network best practise is to install:

2 x A24 traps per acre when targeting rats.

Around the farm, orchard or other food rich site a greater density of traps may be required.

Trap trials

DOC have done the trialling for you! The New Zealand Department of Conservation stand behind Goodnature traps as a reliable and effective tool for controlling rats. The AIHT’s have done it, as have DEFRA, used correctly, you will have great success.

Purchase a Goodnature Digital Strike Counter

Want to know how many pests your traps have killed? Install a Goodnature Digital Strike Counter. A great monitoring tool, this gadget registers a count every time your trap fires. It is particularly useful for collecting data where scavenging is a regular occurrence – at trap sites everywhere!

We can provide you with a quote

If you require a quote for a funding application, or for a large project please contact us directly. We are happy to offer the services of Vance Paines, our technical guru for consultancy.

Zero waste

Goodnature CO2 canisters are not reusable however they can be recycled with your household recycling.

The lure bottle is HDPE and is recyclable as long as it has been cleaned first. The lure bottle cap is also recyclable.

The traps have been designed for longevity in the field, and in a manner that allows us to service them if required so they continue working. We can also receive and recycle any unused traps.

Use rodent detector cards

To get the best results from your A24 rat traps ensure you use Goodnature Rodent Detector Cards to find suitable sites for the traps. Not every trap site is equal, and the detector cards will quickly reveal the better sites.

Set traps away from food competition

Rather than setting your trap near an existing food source for pests, install the traps away from food competition for better results.

If your trap is already installed near a compost site or other excellent food source you may have to remove the food source or restrict the pests’ access to that site. If pests are in the habit of accessing a regular source of food you may have to break that pattern to get them interested in the lure within the trap.

Pre-feeding with the lure pouch will dramatically increase catch rates, give it a go!

If you need extra assistance give Goodnature a call!

The traps did not strike anything on the first night

We usually establish a landscape/grid operation where it is not critical that all animals are affected immediately, only that they are attracted to the trap by the formula; and it is ‘armed’ when they interact with it. This may happen on the first night, or after many nights; when they are in this area of their home range. Timing is not critical since control is achieved over a period of weeks, and then maintained over longer periods.


How to trap stoats

Use target specific Goodnature stoat formula in the A24 Rat & Stoat Trap. Set the trap near the edge of a stream/waterway, on a ridge, track, or on a crop margin/hedge 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.

Keeping Hedgehogs Safe


Be aware of hedgehogs, these are a protected species in decline. A well-placed A24 set at 12-15 inches above the ground will make it difficult for entry. Hedgehogs may scale log piles but they are not built to climb vertically. If your detector cards show hedgehog activity in your area, it is important to do everything you can to stop interaction with the trap. This can be achieved with our UK specific formula for rats, building up around the entrance of the tunnel to restrict access, or used in conjunction with the excluder tunnel we sell you can help protect this species.
