This is the time of year these insects seek out a cozy place to hide for the cold winter months. The Multicolored Asian Lady Beetle is easily identified by her Volks Wagon Bug like silhouette, shiny red to orange and sometimes yellowish body with black markings. Ladybugs congregate twice a year, during the spring as they come out of hiding and again in the fall to look for a winter home.
Ladybugs have a particular fancy for highly reflective colors.
This attraction for brightly colored objects is an innate behavior originating in their native Japan, where they overwinter in white limestone cliffs. And so, it is natural for them to be attracted to your house, especially if it is white. They may also pick a particular part of a house like a bathroom window because of brightly colored curtains. Ladybugs, once attracted to your house, find their way inside through small gaps or cracks in siding and around doors and windows. Once inside they can be quite bothersome.
