Best Rat and Mouse Traps, and How to Use Them
Snap traps sized for the animal are the standard. Put them inside covered boxes where pets and kids live, set them along walls with the trigger toward the wall, and use more than you think you need.
Updated November 4, 2026
The best trap for most homes is the simplest: a snap trap of the right size, placed correctly. The CDC recommends snap traps for reducing rodent populations around the home and recommends against glue traps and live traps. The difference between traps that work and traps that sit untouched is usually placement, bait and patience, especially with rats.
This article compares the main trap types, explains how to set them and covers when bait stations make sense.
Snap traps
Snap traps are cheap, quick and reusable. The CDC notes there are different traps for mice and rats; a mouse trap will only injure a rat, and a rat trap is less sensitive to a light mouse. Plastic snap traps with a wide trigger plate are easier to set and work well on runways.
Pros: inexpensive, fast kill, easy to check, no poison in the house. Cons: must be placed carefully around kids and pets, and need checking daily.
Covered trap boxes and stations
A covered box or tamper-resistant station holds a snap trap inside so only a rodent-sized animal can reach it. UNL extension recommends placing traps inside boxes or bait stations to keep children, pets and non-target animals away from them. Boxes also hide the catch from view and make traps easier to use in garages, crawl spaces and along outside walls.
For Richmond homes with dogs, cats or small children, boxed traps are the sensible default.

Electronic traps
Battery-powered electronic traps kill with a shock inside an enclosed chamber. They are enclosed and easy to empty, which some homeowners prefer. They cost more than snap traps and need fresh batteries. Use the size made for the animal you have.
Traps to skip
- Glue traps. The CDC recommends against them for home use because a trapped rodent can urinate from fear, increasing your exposure to disease. They also catch non-target animals.
- Live traps. The CDC also recommends against these for the same reason, and released rodents often come back or move into someone else's house.
- Multiple-catch and cage traps for rats. UNL extension notes cage and multiple-catch traps are not recommended for rats because they are not as effective as other traps.
How to place traps
- Along walls. The CDC suggests placing traps against the wall with the baited end next to the wall, forming a T, because rodents run along edges.
- Where you see signs: droppings, gnaw marks, nesting material, urine stains.
- In closed areas: behind the stove and refrigerator, in the back of cabinets and drawers, and in attics, basements and crawl spaces.
- Many of them. UNL extension advises using more traps than you think are necessary. For an active kitchen, a dozen mouse traps is reasonable.
- Out of reach of kids and pets, or inside boxes.
Bait and patience
The CDC suggests a small amount of chunky peanut butter. UNL extension lists peanut butter, nutmeat, marshmallow, hot dog, bacon and pepperoni as attractive baits for rats and suggests securing bait to the trigger. Use a pea-sized amount so the rodent has to work at the trigger.
Mice are curious and often get caught quickly. Rats are wary of new objects; UNL extension says it is common for rats to wait up to two weeks before interacting with traps. The CDC suggests pre-baiting: bait traps without setting them so rats get used to them, then set them once the bait is being taken.
Check traps daily, dispose of rodents with gloves and disinfectant as the CDC describes, and reset. The CDC's guide: if nothing is caught for a week and there are no new signs, the rodents are gone.
Where traps go in a Richmond house
In most homes here, three spots matter more than the rest. The first is the crawl space or basement, along the sill and next to pipes that rise into the kitchen and bathrooms; our crawl space article explains why. The second is the kitchen: under the sink, behind the stove and refrigerator and in lower cabinets. The third is the garage, along the walls and behind stored items. Attic traps make sense when you find droppings there.
Outside, rat traps in covered boxes along the foundation, fence lines and near burrows catch Norway rats before they get in. Keep outdoor traps where pets and wildlife cannot reach them, and check them every day.
What about bait stations?
The CDC suggests poison bait or bait stations only for mouse and rat infestations that persist, and recommends EPA-registered products. Under EPA rules, consumer rodenticides must be ready-to-use bait stations with block or paste bait, and stronger second-generation anticoagulants are limited to professional use. Bait has two downsides inside a home: rodents can die inside walls and leave a smell, and bait can harm pets and wildlife. Outdoors, along a foundation, locked stations placed by a professional are more common. Ask any provider what they plan to use.

Questions people ask
What is the best mouse trap?
A well-placed mouse-sized snap trap, ideally inside a covered box if you have kids or pets. Placement and quantity matter more than brand.
What is the best rat trap?
A rat-sized snap trap in a covered box, pre-baited for a few days before setting because rats avoid new objects.
Are glue traps humane or effective?
The CDC recommends against glue traps in homes because they can increase disease exposure. Snap traps are the standard.
How many traps should I use?
More than you think. Several per room with activity for mice, and multiple traps along each runway for rats.
What bait works best?
A small amount of chunky peanut butter is the CDC's suggestion. Nesting material like cotton also attracts mice.
