Ladybug (Lady Beetle – Lady Bug)


  • Color: brightly colored, typically red, brown, or tan with black spots; some are black with red spots.
  • Size: 1/16 to 1/4 long
  • Adults are hemispherical in shape.
  • Larvae are flattened and spindle-shaped with warts or spines on the dorsal (i.e., back) side.

Habits of Ladybugs:

  • Eggs are orange and are laid on end in single or multiple groups of 12 on plants infested with aphids.
  • In the fall, adults seek protected areas in which to overwinter. Preferred areas are beneath rocks, bark, leaves, landscape timbers; however, occupied structures are also suitable.
  • They are beneficial because the larvae and adults eat a variety of outdoor ornamental pests, e.g., aphids, mealybugs, whiteflies, scale, other soft bodied insects and their eggs.
  • Adults are attracted to light and often are seen in window sills and light fixtures.

Damage From Ladybugs:

  • In the fall, the adults become a nuisance when they emerge from their hibernation sites in walls and fly around the house.
  • They pose no threat to health and property.

Look for:

  • Aphids, scale, and other soft-bodied insects on exterior plants that serve as ladybug prey.

How to Control Ladybugs:

Lady Bugs

  • Exclusion is the best method of control and can be accomplished by sealing external cracks, gaps in siding, and openings around door and window frames.
  • Similar areas on the inside of the house should be sealed to prevent ladybugs from entering the interior from wall voids and voids between floors.
  • Screens should fit tightly and un-screened doors and windows should not be left open.
  • Soffit and ridge vents which are also points of entry should also be screened.
  • Once beetles are inside, the best course of action is to use a vacuum cleaner for removal, and then remove, tape and discard the vacuum bag, or release the beetles outside away from the house.
  • Light traps can be used effectively in some situations in order to reduce indoor infestations.
  • Spraying indoors for these beetles is of no value and provides little relief from the problem.
