How To Identify Ladybugs

Ladybugs come in a variety of colors including red, orange, yellow, brown, and even shiny black. they usually have distinctive markings which include dark spots. They are broadly oval and have a dome shape, similar to that of a half of a pea. Adults grow between 1/31 -3/8th of an inch in length.

Why Do I Have A Ladybug Problem?

Ladybugs live outdoors and are beneficial insects because they eat other plant-eating insects like aphids, mites, and mealybugs. When the weather cools, ladybugs will enter homes and other buildings to overwinter in. They move into attics, behind walls and underneath floors. Ladybugs can become quite an annoyance, emerging on warm sunny days and swarming on windowsills.  

Are Ladybugs Dangerous?

No, ladybugs are not dangerous. They are generally considered to be a nuisance pest. However, some species can trigger allergy attacks in people. They also excrete a yellow, foul-smelling fluid that they use as a defense mechanism. The fluid will stain upholstery, furniture and other items that it comes into contact with.
