Colorful and harmless ladybugs serve a purpose in the food chain and many cultures consider them signs of good luck. Unfortunately, the same can’t be said for their cousins, Asian lady beetles. Our NJ pest control technicians explain why you should be on the lookout for this fall invader.
Difference Between Lady Asian Beetles and Ladybugs
Ladybugs are more accurately known as lady beetles, and their colors and markings are similar to their Asian counterparts. The latter can be distinguished by a white spot behind the head along with a M-shaped black mark.
Why Asian Lady Beetles Are Not Welcome Visitors
As temperatures cool down in fall months, Asian lady beetles join other insects seeking shelter inside warm homes. Once inside, they’re not gracious house guests.
• Unlike the less aggressive native species, Asian lady beetles will bite. While not painful, their bite can result in allergic reactions such as hives, coughing and conjunctivitis, better known as pink eye.
• All lady beetles secrete a yellowish, foul-smelling fluid that can stain walls, furniture and carpeting.
• In rare instances, Asian lady beetles have been eaten by dogs who then developed ulcers in the mouth and esophagus.
