In indoor spaces and gardens alike, mice pose a serious threat to your entire family—children, adults, and pets can come into contact with their droppings and, consequently, with pathogenic microorganisms. This time of year sees a surge in mouse activity as they try to enter homes in search of food and warm environments.
These animals are incredibly agile and cunning. Their abilities make them particularly difficult to catch: they can jump up to 20 inches and squeeze through gaps as thin as a millimeter. Mice are also known for their prolific breeding—a single female can produce up to five litters per year, with each litter containing between 3 and 14 pups. That’s why a rodent control intervention must be as swift as possible.
Rodent Control in Indoor Spaces
When a mouse gets inside your home, it will hide in every nook and cranny, only emerging when it knows it can search for food undisturbed. For this reason, indoor spaces are best treated with glue traps—boards made of tempered hardboard covered with a thick layer of special adhesive that won’t freeze, won’t drip, and contains a food attractant.
Rodent Control in Outdoor Spaces
Safe and effective mouse control in open areas requires the use of rodenticide bait stations. Products containing toxic active ingredients must be protected inside a rigid plastic box, securely fastened to the ground, wall, or post, tamper-proof, and locked with a key. The placement of these stations will be determined by the characteristics of the environment, to intercept mice and prevent them from approaching indoor spaces. Their use aims to ensure that children and non-target animals cannot come into contact with the poisonous bait.
For severe infestations, some homeowners turn to stronger measures. If you're dealing with persistent raccoon problems as well, check out our guide on the best poison for raccoons for effective outdoor pest control.
Useful Tips to Prevent Infestation
To avoid a troublesome infestation, here are some best practices:
- Doors, holes, and cracks: Mice can squeeze through any type of gap to access the inside of a building. It’s important to ensure that doors and walls have none, and to seal any holes from the outside and install brush strips around doors.
- Ceiling openings: Some construction errors can leave openings in floors, between rooms and floors, or in walls. Utility lines, in particular, often serve as ideal hiding spots for mice and must be filled with suitable sealing material.
- Elevator shafts: Mice are excellent climbers and can even run quickly up smooth walls. The elevator motor room is an ideal area for them to nest undisturbed.
- Food and waste: Food scraps are a strong attractant for mice in the home. Trash bags should be stored in an airtight container or a metal mesh bin and cleaned frequently.

Understanding Mouse Behavior
Mice are nocturnal and prefer to stay close to walls and edges. They have poor eyesight but excellent hearing, smell, and touch. Their whiskers help them navigate tight spaces. A mouse can fit through a hole the size of a dime, so even the smallest crack is a potential entry point. They are also known to gnaw on materials like wood, plastic, and even soft metals to enlarge openings or access food.
Why Mice Are Dangerous
Mice are not just a nuisance—they carry diseases such as hantavirus, salmonella, and leptospirosis. Their droppings and urine can contaminate surfaces and food, and they can trigger allergies and asthma, especially in children. Additionally, their constant gnawing can damage electrical wiring, insulation, and structural elements, creating fire hazards and costly repairs.
Integrated Pest Management Approach
Effective mouse control combines exclusion, sanitation, and population reduction. Start by sealing all entry points with steel wool or caulk. Keep your home clean and free of crumbs, and store food in rodent-proof containers. Use traps or bait stations strategically, and monitor them regularly. If the infestation is large, professional pest control may be necessary to ensure complete eradication.
FAQ: Mouse Control Questions
How do I know if I have mice?
Look for droppings (small, dark, rice-shaped), gnaw marks, greasy rub marks along walls, scratching sounds in walls or ceilings, and nests made of shredded paper or fabric. You may also notice a musky odor from their urine.
What is the best way to get rid of mice?
A combination of sealing entry points, removing food sources, and using traps (snap traps or glue boards) is most effective. For outdoor infestations, rodenticide bait stations can be used, but always follow safety guidelines to protect pets and wildlife.
Can mice climb walls?
Yes, mice are excellent climbers. They can scale rough surfaces like brick and wood, and even smooth walls if there is enough texture. They can also jump up to 12 inches high and run along wires and pipes.
How quickly do mice reproduce?
Mice reproduce rapidly. A female can have 5 to 10 litters per year, with each litter containing 3 to 14 pups. Young mice reach reproductive age in about 6 weeks, so a small problem can become a large infestation in just a few months.
Are glue traps humane?
Glue traps are controversial because they cause stress and slow death. If you use them, check them frequently and humanely euthanize trapped mice. For a more humane approach, consider live traps or snap traps that kill instantly.
