ABOUT ASIAN BEETLES
Asian Beetles are a part of the lady bug group. Most are highly beneficial. In the autumn, they seek shelter before overwintering in structures and become nuisance pests. They are found throughout most of the US and Canada.
MEASURES TO CONTROL ASIAN BEETLES
Use preventative barriers aimed at adults before they congregate and enter structure - preferably in June or July. Screen all vents. Seal your outdoors and indoors! Do not kill in wall voids, as dead bodies attract beetles. Instead, wait until summer when live overwintering adults are out of the wall. Vacuuming can bring temporary relief but the hose may need to be replaced due to the odor.
CHARACTERISTICS OF ASIAN BEETLES
Asian Beetles are 1/32 to 3/8" long with broadly oval bodies to nearly round bodies. They are yellow to dark reddish orange with several black spots. Their heads are partly to completely concealed from above with very short antennas. Their larvae look like tiny flat alligators with numerous spines. Adults fly in afternoon sunlight and orient to structures having high contrasting silhouettes to settle. Overwintering adults emerge from hibernation and lay eggs in single or multiples of 12 on plants infested by aphids, mealybugs, scale insects and more.
