When are mice and rats most active?

“I keep hearing noises in my walls late at night, but never actually see a mouse. When are mice and rats most active?”

Mice and rats are nocturnal, so they do most of their moving, feeding, and nest-building after dark. That's why you're hearing scratching or scurrying in your walls or ceiling at night rather than spotting them during the day. Generally, they’re most active the few hours right after sunset and again just before dawn, when they feel safest moving around under cover of darkness.

Activity tends to follow a predictable pattern:

• A burst of movement in the hour or two after dusk, as rodents leave their nests to feed
• A quieter period overnight while they return to shelter between feeding trips
• A second, shorter wave of activity in the early hours before dawn

Rats follow a similar rhythm to mice, though they tend to be more cautious and may take longer to investigate new objects, like traps, before approaching them.

Because nighttime activity makes rodents hard to track on your own, a professional inspection is often the quickest way to understand the real scope of the problem. Our technicians know where to look for daytime hiding spots and can set up monitoring that works around the clock. 

If you're dealing with mice, our mouse control team can help identify entry points and activity patterns specific to your home. For rats, our rat control service takes the same approach, tailored to their slightly different habits and larger size.
