Lady Beetles: Friend or Foe?
Despite the obvious benefits of ladybugs, some people consider them pests. During cold winter months, ladybugs are not active. But during times of warm, then cold temperatures, large groups of ladybugs can be found outside windows, doors, walls and porch decks looking for food. They are particularly attracted to light colored structures with southwest exposures. On sunny days in the winter, the beetles become active again and begin looking for food. Many seem to find their way indoors through cracks around door and window frames.
It is important to know that ladybugs do not bite, sting or carry human diseases. Nor do they feed on wood, clothing or human food and they do not reproduce inside the home.
