Is a Asian ladybug dangerous

Answer 1

Ladybugs are natural predators to many pest insects, including aphids, scale insects and other sap feeders (an adult ladybug can eat up to 1,000 aphids a day). As such, they are primarily viewed as beneficial insects. Use of insecticides may reduce the ladybug population and may cause increased damages to crops as well as garden plants.

Preventing the ladybugs from entering the building is the best approach to keeping them from becoming a nuisance in the fall and winter. Caulking the exterior cracks and crevices and filling the larger openings with cement, urethane foam or copper mesh is a permanent way to keep them out. The time to do this is late spring or summer, before the adults begin flying to buildings in search of over wintering sites. Repair damage window screens and installing screening behind attic vents which are common entry points for the ladybugs. Install tight-fitting door sweeps or thresholds at the base of all exterior entry doors. Vacuuming would be the easiest way to collect them once they are indoors and if you wish to release them outdoors you should place a handkerchief inside the hose. Using insecticides indoors for control of the ladybugs is not typically recommended unless the infestation is heavy and is a perennial problem. They like to burrow underneath insulation and once established they would breed over the winter months.
