Creepy, Smelly, and Downright Annoying Bugs You’ll Find Lurking in Your Home

What it looks like: You’re probably very familiar with this one. Ladybugs are tiny, oval, winged beetles that are usually between 1 to 10 millimeters (mm) in length, depending on the species. They are typically bright red with black spots.

Where you’ll find it: You can find them in your home in autumn between September through November, when the temperatures drop and they seek a warm spot for winter. They like to gather together within crevices, like cracks around windows and door frames, soffits, attics, wall voids, and the area behind fascia boards and exterior siding.

Can it harm you? These beetles are believed to trigger allergies, ranging from eye irritation to asthma, potentially because they emit a stinky, yellow secretion when they feel they’re in danger. Lady bird beetles also can bite (it feels like a pinch), but they are not poisonous and are rarely harmful.
