At some point, every homeowner in Maryland is bound to encounter mice or rats, especially if you live in an urban area like Baltimore.
However, field mice, deer mice, and house mice are also incredibly common in rural and suburban areas all across Maryland during the winter.
Sounds of scratching, nibbling food, and droppings around your house are signs that can point to the presence of mice that require a quick solution. Rodents are notorious for carrying dangerous diseases, including hantavirus.
Mouse traps are a tried and true method favored by both homeowners and pest control specialists.
However, the efficacy of mouse traps depends largely on application, and traps are rarely effective for larger infestations.
This guide will discuss how mouse traps work, different types of traps, and important information on how to use traps effectively.

How Mouse Traps Work
Mouse traps work by luring mice in with a bait that attracts them to a trap where they are killed using a snapping mechanism or an adhesive.
Traps can take a few days to lure in mice, as they are cautious, but peanut butter can be used as a fast-acting bait. Once the mouse is lured in, it’s either trapped or killed immediately.
The specifics of how a trap works depend on its design, and the choice is yours. In any case, traps must be placed near areas where mice typically travel or feed in order to be effective.
Compared to other rodent control methods, mouse traps can be effective for small rodent sightings, but may not be sufficient for larger homes or long-term prevention.
Pros of Using Mouse Traps
- Immediate results: Unlike poisons, traps can remove mice from your home right away.
- No secondary poisoning: Safer for homes with pets and kids, since no toxic bait is involved.
- Reusable and cost-effective: Especially true for snap or electronic traps.
- Allows monitoring: You can confirm whether you’ve caught a mouse, helping gauge the infestation size.
When used correctly, traps can be an incredibly effective solution for immediate and ongoing pest-control plans.
Cons and Limitations of Mouse Traps
- Limited coverage: A few traps may not control large infestations.
- Requires maintenance: You must check and reset traps daily.
- Placement matters: Incorrect positioning drastically reduces effectiveness.
- Temporary fix: Traps only catch existing mice. They don’t stop new ones from entering.
If mouse traps fail to capture mice or get the infestation under control, additional steps must be taken. It’s best to call in a pest control specialist for extreme cases.
Types of Mouse Traps
The first step in understanding the effectiveness of traps is learning about the different types.
Which is best depends on your home, comfort level, and the size of your infestation. Here are the most common mouse trap designs:
Snap Traps
Snap traps are the most well-known type that work quickly and efficiently. When baited and set properly, they can kill mice instantly. They are also inexpensive and reusable.
These are a great choice for homeowners who want to catch a mouse fast, but proper baiting and placement are key. They must be set nearby commonly traveled routes for mice.
Only a small amount of bait, like peanut butter, should be used to ensure it can be triggered when a mouse feeds.
Glue Traps
Glue traps are simple adhesive boards that will trap rodents as they run across them. They are easy to use, but are generally viewed as inhumane, as mice trapped by them will suffer before they die.
They will also collect pet hair, dust, and debris, reducing their effectiveness over time.
Glue traps are not a good choice for Maryland homeowners looking for humane mouse traps. They can also pose risks for pets or children if placed in open areas.
Electronic Traps
Modern electronic trap designs use a high-voltage shock to kill mice instantly. They’re considered humane and sanitary, as you don’t have to touch mice within them.
They’re reusable, enclosed, and often have lights to let you know when they’ve trapped a mouse, making the extra expense worthwhile for ongoing pest control.
Live-Catch Traps
Live-catch traps are the best choice for homeowners who prefer not to kill mice. These cage-style traps simply lock mice within once they feed on the bait without causing injury.
They’re enclosed, reusable, and a budget-friendly and sanitary solution.
The key to success here is using the right amount of bait to trigger the trap. Then, the mouse captured needs to be released miles away from the home to prevent it from returning.
Common Mistakes People Make With Mouse Traps
Even the best traps will fail if they’re not used properly. Many homeowners will make mistakes as they learn the best practices for capturing mice.
That said, it’s nice to know what to avoid when getting started. Common mistakes include:
- Using too much bait. Only a small amount of bait is necessary. Too much allows mice to feed without setting off a trap.
- Placing traps in the wrong spots. Mice tend to travel along walls and baseboards, avoiding exposure. Placing traps in open areas will likely fail to attract them.
- Not using enough traps. A single mouse sighting likely means more are hiding. It’s recommended to set six to eight traps in most homes.
- Neglecting sanitation. Traps should be kept clean and stocked with fresh bait. Crumbs and debris will make a trap less appealing to mice.
Comparing Traps vs. Other Rodent Control Methods
Mouse traps are a highly effective and favored solution to rodent problems for a reason. They’re just one solution, though. For the best results, you should consider the following:
- Baits: Poison bait solutions will kill mice and are great for large-scale problems. However, they introduce a risk to pets and children.
- Exclusion: Making sure mice can’t get in is critical to controlling infestations. Sealing cracks and utility openings around your home keeps pests from entering and causing problems in the first place.
- Professional pest control: If DIY methods aren’t working, a licensed pest control specialist should be consulted to help come up with a pest control plan.
There’s simply no replacement for professional help for heavy infestations.
Without the proper resources and experience, it can be extremely difficult for homeowners to deal with major mouse problems on their own.
Safety Considerations for Homes With Kids and Pets
Traps aren’t always low-risk or even discrete. If used improperly, they can be hazardous to pets and children and ineffective.
Always keep traps away from areas where pets and children can access, such as behind appliances and furniture.
Avoid glue or snap traps in living areas. You should also regularly check and clean traps to avoid sanitary issues.
Best Practices for Effective Rodent Control
Using mouse traps isn’t difficult when you know what to avoid. When using a mouse trap to deal with an infestation, keep the following best practices in mind:
- Identify the source. Look for gnaw marks, droppings, and grease trails to locate nesting areas.
- Set multiple traps. Use multiple traps in high traffic areas for the best results.
- Use the right bait. Peanut butter works best, with chocolate and oats being great alternatives. Experiment with different baits for the best results.
- Check traps daily. Remove mice and promptly reset traps frequently for the best results.
- Seal entry points. Close off any gaps, cracks, and utility openings to keep more mice from entering.
- Keep it clean. Eliminate food crumbs and trash, and keep containers sealed.
- Call a professional. Schedule a rodent control inspection if the traps don’t work within one week.
Mouse traps are a great first step for DIY rodent control, but shouldn’t be relied on exclusively, especially if the problem persists, mouse traps stop working, or you spot more than one rodent in your house. In that case, professional rodent control is the only safe option for your home.
