Finding a bug crawling across your wall can immediately make you wonder where it came from—and whether there are more hiding somewhere.
Usually, one insect isn’t a reason to panic.
It may simply have entered through an open window, damaged screen, or tiny gap around a door. Light, warmth, and shelter can also attract insects indoors.
But before you ignore it, take a closer look.
Where you found the bug—and whether you keep seeing others—can reveal useful clues about conditions inside your home.
