Goodnature A24 Rat & Mouse Trap Review 2026: Does It Work for Homeowners?

The Goodnature A24 Rat & Mouse Trap is a smart solution for persistent rodent problems, especially for those who want a poison-free, low-maintenance approach. It excels at long-term, outdoor rat control with minimal reset work. The catch: it’s a higher-end investment and not ideal if you need instant, high-volume results overnight.

How We Evaluated This Product

Our review of the Goodnature A24 focuses on factors that actually impact homeowners and renters: kill effectiveness on both rats and mice, ease of installation, ongoing maintenance, safety for people and pets, and real-world costs over time.

We compared the A24’s performance and practicality against leading alternatives like the Victor Electronic Rat Trap and classic snap traps, considering use cases from single-apartment infestations to large outdoor properties.

Our analysis draws from product specs, third-party field data, and hundreds of verified user reports. This helps you decide if the A24 fits your needs - or if a lower-tech or cheaper solution would serve you better.

Quick Verdict: Should You Buy the Goodnature A24?

The Goodnature A24 stands out for those who need an automatic, poison-free rodent trap that runs for weeks with minimal hands-on attention. It’s especially strong in outdoor, recurring infestations where snap traps constantly fail or become a chore to reset. If you need to wipe out a massive infestation in a single night, or want the lowest upfront cost, this isn’t the trap for you.

Who Will Benefit Most from the A24?

• Homeowners with persistent rat or mouse problems in sheds, garages, gardens, or along fences - where traditional traps get outsmarted or become labor-intensive.
• Anyone prioritizing safety: no poisons, no risk of secondary poisoning to pets, wildlife, or children.
• People who want to “set and forget” - the A24 resets itself after every kill and can go weeks between checks.
• Not ideal for: apartment dwellers with a one-time mouse issue, or anyone needing to kill a dozen rodents in a single night indoors.

Key Pros and Cons at a Glance

• Self-resetting for up to 24 kills per CO2 cartridge - no need to reset manually after each rodent.
• CO2-powered - works anywhere, no batteries or outlets needed.
• Enclosed bait and instant kill mechanism - humane and less messy than glue boards or slow-acting poisons.
• Premium price tag - ongoing costs for CO2 and bait refills.
• Doesn’t contain dead rodents, so you may need to remove them if visible.

How the Goodnature A24 Trap Works

The A24 uses a compressed CO2 canister to deliver a quick, lethal blow to any rodent that enters. This lets it reset itself automatically after every activation, so you’re not constantly checking and resetting like with snap traps.

CO2-Powered Self-Resetting Action

• Each CO2 cartridge powers the trap for up to 24 kills. When a rat or mouse triggers the internal mechanism, a piston fires instantly - then retracts, ready for the next rodent.
• The trap stays “armed” after every kill, letting it keep working without intervention for weeks or even months - ideal for outdoor or hard-to-access spots.
• No electricity, batteries, or extension cords required. This is a major advantage for sheds, barns, and perimeter fences.

Lure and Kill Mechanism Explained

• The A24 uses a proprietary long-life bait, optimized for rats and mice. It’s formulated to stay attractive for weeks, so you’re not constantly re-baiting.
• Rodents are drawn in by the scent. When they reach up to nibble the lure, they trigger a piston strike that delivers a rapid, humane kill - much faster and less stressful than glue traps or slow poisons.
• The bait is tucked inside a cradle, minimizing mess and making it tough for non-target animals or pets to access.

The A24’s approach offers a practical, low-mess solution for ongoing rodent pressure - especially in areas where rodents are smart enough to avoid basic snap traps. For homes or buildings with regular rodent incursions, it’s a strong alternative to constant poison use or daily snap trap checks.

Installation and Setup Process

Setting up the Goodnature A24 is straightforward, but placement and safety checks matter if you want it to work as advertised. Start by identifying where rats or mice are most active - look for droppings, greasy marks, or gnawing near walls, outbuildings, or known runways.

Placement Tips for Maximum Effectiveness

• Install the A24 directly along rodent runways, fences, or exterior walls - rodents hug edges, so mid-yard placement rarely works.
• Mount at the manufacturer-recommended height (usually 4-6 inches above ground) for rats; slightly lower for mice. Use the included mounting bracket for fences, trees, or posts.
• Outdoors is where the A24 shines. Indoors, it can work in garages or basements, but large, open spaces are best - it’s less effective in cramped cupboards or behind appliances.

Initial Assembly and Safety Checks

• Securely screw in the CO2 cartridge by hand until you hear a short hiss - this signals the seal is engaged. Check for leaks by listening for ongoing hissing or feeling for cold air; if present, unscrew and reseat the canister.
• Load the bait into the cradle without touching it directly - gloves help prevent scent contamination, which can make the lure less attractive.
• Arm the trap only after it’s mounted and baited. Always keep your hands clear of the firing mechanism. Double-check the safety lock if you need to move or service the trap.

Performance in Real-World Use

So how does the Goodnature A24 stack up when rodents are actually present? The data - and user reports - show strong performance on rats, with some caveats for mice.

Effectiveness Against Rats vs Mice

• The A24 is calibrated to reliably kill adult rats - its trigger force and strike power are optimized for this target. In user reports, catch rates for rats are consistently high, especially when the trap is placed outdoors along established runs.
• Mice are lighter and sometimes too small to trigger the piston, especially compared to ultra-sensitive snap traps like the Tomcat Press 'N Set Mouse Trap. If your main problem is tiny field mice, you may see fewer catches - though some users report better results with strategic placement and pre-baiting.
• For mixed infestations, the A24 often catches more rats than mice. For heavy mouse-only problems, a combination of A24 and snap traps may deliver better coverage.

Maintenance and Monitoring Needs

• Expect 3-6 months of use per CO2 cartridge with moderate activity. Heavy infestations can drain the canister faster, so check kill counters or use the optional digital strike counter.
• Bait lasts for weeks, but freshening it every month keeps it attractive. If catch rates drop, swap in a new bait pouch.
• Dead rodents are not contained. In open areas, scavengers often remove them, but in visible spots, you’ll need to clear carcasses to keep your property clean.

Safety and Environmental Considerations

One of the biggest strengths of the Goodnature A24 is its safety profile. There are no poisons, and the mechanism is designed to kill instantly, minimizing suffering for the animal and risks for everyone else.

Non-Toxic and Humane Design

• No rodenticides, so there’s no risk of secondary poisoning for pets, predators, or scavenger wildlife. This is a major plus compared to anticoagulant baits.
• The kill is instantaneous - no prolonged suffering like glue boards or slow-acting poisons.
• Bait is enclosed, and the mechanism is housed - so accidental contact is rare if the trap is installed properly and out of reach.

Potential Risks and Precautions

• CO2 canisters are under pressure. Always store and dispose of them per manufacturer instructions, and never tamper with the canister while armed.
• Install out of reach of children and curious pets. The strike force is enough to injure small animals if triggered by mistake.
• While rare, non-target animals (like squirrels or birds) might access the trap if it’s poorly placed. Proper mounting and location mitigate this risk.

If you want to double down on rodent safety, pair the A24 with high-quality exclusion materials - see our Best Rodent-Proofing Materials and Products 2026 guide for options that block re-entry after you control the current population.

Cost Analysis and Ongoing Expenses

The A24 falls into the premium trap category. While it’s a bigger upfront investment, the automatic reset and reduced labor can justify the price for persistent, outdoor, or large-property users.

Upfront Price vs Traditional Traps

• The A24 is a higher-end investment, compared to budget-friendly snap traps like the Tomcat Press 'N Set Mouse Trap, which are economical for short-term, indoor issues.
• Your initial purchase includes one CO2 canister and bait, enough for 24 kills before refills are needed.
• Over one season, you might spend less on refills than on dozens of disposable snap traps - especially if you’re handling a chronic infestation.

Long-Term Value and Consumable Costs

• CO2 cartridges and bait refills run in the mid-range category. Expect to replace them every 3-6 months, depending on rodent activity.
• Labor is where you really save: you’re not checking and resetting traps every day. For outdoor, perimeter, or vacation properties, this adds up to real convenience.
• Heavier rodent pressure means more frequent refills, which can push ongoing costs higher. For mild problems, the A24’s value grows over time as you use fewer consumables.

For a full prevention plan, combine the A24 with proven exclusion strategies. Our Rodent-Proofing & Prevention guide covers sealing entry points and choosing the right barriers so you’re not just trapping, but keeping pests out for good.

Comparison: Goodnature A24 vs Competing Traps

Let’s see how the Goodnature A24 stacks up against two common choices: the Victor Electronic Rat Trap and the Tomcat Press 'N Set Mouse Trap. Each has a different set of strengths and best-use scenarios.

Goodnature A24 Rat & Mouse Trap by Goodnature (A24)

The A24 is built for users who want to set a trap and let it work for weeks or months with little attention. Its self-resetting, CO2-powered piston can handle the daily grind of outdoor rodent pressure - especially in places like chicken coops, compost bins, fences, or garages.

• Self-resetting for up to 24 kills per cartridge - dramatically reduces manual labor compared to snap or electric traps.
• Weather-resistant and safe for use outdoors, in outbuildings, or along property lines - no risk of electrical malfunction.
• Long-life bait system attracts both rats and mice, but works best for rats due to trigger sensitivity.
• Higher-end investment up front, but pays off over time if you have recurring problems and value convenience.
