From this website you provided: ' The exotic Asian lady beetle has had a positive impact in many states because of the beetle's effectiveness in controlling aphids on pecan trees, pine trees, ornamental shrubs, cotton, wheat, tobacco, roses, etc.'
So their not so bad
ALso: ' The Asian lady beetle does not bite, sting, carry human diseases or feed on wood, clothing or food; they also do not reproduce indoors. In spite of annoying populations, these insects are considered beneficial to agriculture and garden landscapes because they feed on harmful aphids and some scale insects associated with trees, shrubs, bushes, low growing ornamentals, roses, wheat, cotton, tobacco, pecans and other crops.'
How did this thing bite you again?
