Oklahoma researchers are issuing a warning about a type of ladybug that can invade homes and act as nuisance pests through spring.
According to a report posted in the Oklahoma Cooperative Extension Service, the Asian Lady Beetles range in color from light orange to deep red and have a varying number of black spots.
The beetles seek out shelter during the fall and winter months and are most active on warm, sunny days following periods of cold weather. The beetles can accumulate in large numbers indoors and when disturbed, will produce an unpleasant odor and yellowish fluid that can stain curtains and clothing. Infestations may also caused allergic reactions in some people.
The ladybugs also bite readily, although the bites cause no serious injuries.
The pests can be controlled by sealing all cracks and crevices in outer walls with mortar or a similar compounds. Caulk should be used to seal openings around windows and doors.
