LADY BEETLES

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.

The best control for ladybugs is to prevent them from entering the house. Seal cracks and crevices using a good silicone or silicone-latex caulk. Replace or repair damaged window screens. Install insect screening (20 mesh maximum) over attic and exhaust vents.

Remove ladybugs inside the home with a broom and dustpan.  There are no pesticides labeled for ladybugs. When it gets cold again, the beetles will become dormant again. The problem may be sporadic throughout the winter months.
