As spring arrives, many people assume pest problems disappear. While some seasonal pests become less active, mice are a different story. We’re often asked if mice living indoors will go back outside when the weather warms. Unfortunately, the answer is rarely simple.
Mice are drawn indoors during autumn and winter. They seek warmth, food and shelter from the cold. However, just because it’s spring doesn’t mean they’ll leave. In fact, mice living indoors often choose to stay once they’ve found a comfortable space.
House mice nest in lofts, wall cavities, behind kitchen units and under floors. These areas provide ideal conditions all year round. Mice can easily find crumbs of food and access to water. Therefore, even in warmer weather, they have no reason to go elsewhere.
Mice are territorial and cautious. Once they find a secure location, they won’t leave unless forced. While some may explore outside, most will continue using their indoor nest. If they’ve already raised young in your home, it’s even less likely they’ll leave on their own.
Also, mice breed throughout the year. Warmer temperatures can increase breeding activity. As a result, the population indoors may even grow during spring. That’s why relying on the weather to fix a mouse problem isn’t effective.
If you’ve had mice living indoors over winter, don’t wait for them to go. Instead, take action now. First, check for common signs. Look for droppings, gnaw marks or shredded material. You may also hear scratching sounds, especially at night. We recommend mouse proofing measures and good hygiene practices. Check under sinks, behind fridges and in loft spaces. These are popular hiding spots for mice. Even if activity seems to have stopped, they may still be present.
Next, seal any entry points. Mice can squeeze through holes the size of a pencil. Use wire wool and sealant to block gaps in walls and around pipes. This step helps stop new mice from entering. Then, remove food sources. Keep dry goods in sealed containers and clean up crumbs promptly. Mice are opportunistic feeders. If food is available, they will stay.
Finally, if you’re unsure, contact our professional London mouse control team. We inspect your home thoroughly and place monitoring traps where needed.
Although spring feels like a time for pests to move outdoors, mice living indoors often stay put. That’s why it’s important to remain vigilant. We’re here to help you keep your home mouse-free throughout every season.
