Box Elder Bugs in northern Nevada
Box elder bugs, black with orange-red markings, are a familiar fall sight across Reno and Sparks, massing on sunny south- and west-facing walls before working their way indoors to overwinter. They breed on box elder, maple, and ash trees, then move to homes as temperatures drop, collecting around windows, siding, and attics. They don't bite or breed indoors, but they show up in frustrating numbers.
Why it matters
Box elder bugs are harmless, they don't bite, sting, or damage the home, but their sheer numbers are a nuisance and their droppings can stain surfaces and fabrics.
