They may be beneficial in the garden, but they aren’t typically welcome indoors. If you do resort to physical removal, Braman urges you to be careful. Lady beetles do have a defense mechanism. “During this temperature transition stage, they’re just looking for a place to stay for the winter,” she said. “We’ve never radio-collared them to be sure, but chances are, the ones you sweep out aren’t going to come back in.” Braman’s work focuses on integrated pest management. This pest-control method encourages the use of beneficial insects such as lady beetles. “Homeowners should actually show these lady beetles some gratitude,” said Vicki Owen, a UGA Extension agent in Crawford County. “When you find where they’re coming into your home, you’re finding somewhere that cold air can come in, too.” Asian lady beetles are one of several species in Georgia. But they’re the only one here with the annoying houseguest habit, said Kris Braman, a University of Georgia entomologist.center_img Owen recommends sweeping up the beetles and physically returning them outdoors. By Sharon OmahenUniversity of GeorgiaA roaring fire in the hearth, coats and mittens hanging in the foyer and windblown leaves racing around outside are all signs that winter has arrived. Many Georgians may want to add “lady beetles on the ceilings” to that list. “Lady beetles are the universal feel-good bugs, so it’s unfortunate a few are becoming pests,” said Braman, a researcher with the UGA College of Agricultural and Environmental Sciences. “Lady beetles feed on aphids, an insect that can cause major damage to pecan trees, crape myrtles, roses and many other plants,” she said. “When they’re around to eat the aphids, homeowners may not need to spray insecticides.” Lately, UGA Cooperative Extension county agents are getting a lot of calls statewide about lady beetles. People aren’t calling to praise them for their aphid-eating skills.last_img
