Early Appearance of Autumn Invaders

You may take notice of a couple of insects that are making their bothersome appearance a little earlier than usual. The Asian Lady Beetle and the Boxelder bug, both prominent autumn pests, typically look for residences to hide during the cold months of the year, but are displaying a good amount of activity already this August.

Boxelder bugs inherited their name by their preferred food source, the Box Elder tree. But, you can also find them feeding on the sap and seeds of other trees such as Maple, Ash and some other fruit trees. Their damage to trees is typically minor, they do not bite, and they also do not carry any diseases. They do, although, have the capability to leave behind “waste stains” where they have been. With all of that said, you may still consider them a nuisance when you find them covering the sunny side of your home.

Boxelder Bugs are pretty easy to spot. They are about a ½” long and have a black body with red markings on their wings.

Asian Lady Beetles are around 1/3”-1/4” long, they can be yellow-orange to red and they can have anywhere from 0-22 spots on their wings. Their diet includes plants such as Evergreens, Apple and Maple trees, alfalfa, wheat, cotton, tobacco, and small grains. Asian beetles emit an unpleasant odor and can stain surfaces with their yellowish secretions if disturbed.

Both bugs are most noticeable during the months of September and October. During that time, Boxelder bugs and Asian Lady Beetles can be found congregating in large numbers on the southern sunny and warm side of buildings, trees and rocks. Once the cooler temperatures of winter begin to set in, they will find their way inside of homes to find a protective place to overwinter.

To prevent Boxelder bugs and Asian Lady Beetles from making a home in your residence:

  • Seal off any cracks or crevices in walls, foundations and around pipes
  • Check for loose vents or entry by exhaust fans
  • Sweep and vacuum to remove and release unwanted beetles
  • Repair any torn window screens or door gaps

If the problem becomes too much to handle, it may be best to call a licensed Pest Management professional to assist.
