Asian Lady Beetles in Central Arkansas
The multicolored Asian lady beetle was introduced to the United States from Asia between 1978 and 1981 to combat aphids, scale insects, and other crop pests. Since then, they have spread widely across the country, from Mississippi to the Midwest, Southwest, and Pacific Northwest. They often enter homes in large numbers, becoming a common overwintering pest in buildings and homes.
Asian Lady Beetle Habitat
This species is a formidable predator of agricultural pests and can produce several generations each year. Their tendency to gather in large numbers and infiltrate structures makes them a significant nuisance. Large infestations, with hundreds or even thousands of beetles, can occur inside and on homes. They are commonly found in attics, wall voids, on siding, and inside closets, and are attracted to light.
Asian Lady Beetle Behaviors, Threats, or Dangers
While Asian lady beetles may bite, their bites are not harmful to humans and do not transmit diseases. When disturbed or crushed, they emit a foul odor and can leave stains. In the fall, these beetles seek out crevices and protected areas around homes to overwinter, often congregating in attics, wall cavities, cracks around door frames, and within soffits and wall voids. Inside homes, large numbers of beetles can stain drapery and clothing. Although they cannot survive sub-freezing temperatures, they can live within homes and buildings that provide sufficient warmth and humidity.
If you are dealing with an infestation, always contact a licensed beetle exterminator.
