State Agriculture Department entomologist Mark Mayer says the Asian lady beetles are typically attracted to light-colored homes and structures. They'll congregate on windows and doors.
Homeowners are advised to make sure their windows and doors are properly caulked so the bugs can't find a way inside.
Officials recommend using a vacuum without a propeller if the beetles swarm in a home. Scientists say ladybugs eat pests to flowers and plants and can give off a foul odor if crushed.
