Asian Lady Beetles
Fall of 2021 had a lot of Asian Lady Beetles entering peoples homes. NIX will be on the lookout for these pests in autumn of 2022
During the fall, the Asian lady beetle congregates on the sides of buildings, enters homes and lands on folks as they walk through their yards, and it sometimes bites. The multicolored Asian lady beetle can be easily distinguished from other species of lady beetles by the presence of a black M-shaped pattern directly behind the head. Adults are large for ladybeetles and are about 1/4 inch long and 3/16 inch wide. Coloration varies from bright orange with up to 19 black spots in some individuals to dull yellow with pale or no visible spots on others. Throughout the seasons Nick Cobb has learned when and where to look for these pesky invaders, and if I don’t think they will be here for a season, we would never come and charge you for a service you don’t need or put unnecessary pesticides around your home.
Asian Lady Beetles in Northern Michigan
The Multicolored Asian Lady Beetle is a nuisance pest because the adults tend to congregate and over winter inside buildings in large numbers. To make matters worse, they supposedly release a pheromone that attracts more beetles to the same area. Although these ladybeetles may bite, this bite does not seriously injure humans or spread diseases. If crushed, the beetles will emit a foul odor and leave a stain. The dust produced from an accumulation of dead Multicolored Asian Lady Beetles behind wall voids may trigger allergies or asthma in people.
