Asian Lady Beetle Habitat

This particular species is a hungry predator of crop pests and reproduces multiple times within a year. Their natural inclination to gather in groups and their knack for infiltrating structures often leads to them becoming bothersome pests within buildings. It’s not uncommon to discover hundreds, or even thousands, of these beetles both inside and outside homes. Asian lady beetles can be found residing in attics, wall crevices, clinging to siding, hiding in closets, and they may also be drawn to light sources.

Asian Lady Beetle Behaviors, Threats, or Dangers

While Asian lady beetles are capable of biting, their bites do not pose a significant threat to humans or transmit diseases. When handled or crushed, these beetles release an unpleasant odor and can leave behind stains. During autumn, they actively seek out sheltered spots and crevices near residential structures to spend the winter. Common gathering areas include attics, wall openings, cracks around door frames, as well as within soffits and wall voids. If a large number of beetles manage to infiltrate homes, they can potentially stain draperies and clothing. It’s important to note that Asian lady beetles cannot survive in sub-freezing temperatures, although they can thrive indoors where sufficient warmth and humidity are present. If you are dealing with an infestation, always contact a licensed beetle exterminator.
