Why do I have mice in my house all of a sudden?

You suddenly have mice because they found easy access to your home's food, water, or warmth, often entering through tiny gaps in foundations, walls, or around pipes, especially as temperatures drop in autumn/winter, or due to nearby construction disrupting their habitat. They're opportunistic, so even tidy homes can attract them with crumbs, pet food, or clutter offering nesting spots.

How many mice are in your house if you see one?

If you see one mouse, you likely have several more hiding nearby, as mice are social and live in groups, so a single sighting often signals a larger, established population or the start of one. Daytime sightings or seeing them in open areas often mean the nest is overcrowded, forcing some out, indicating a bigger issue than just one stray. You can estimate the extent by checking for more signs, like droppings or gnaw marks, but assume you have more than one and act quickly to prevent a rapid infestation.
