Lady beetles, also known as "ladybugs" or "ladybird beetles", are familiar insects. They are considered beneficial insects to the environment because they eat other insects. However, in some places ladybugs can become so numerous that they become a nuisance. During this time of year, ladybugs start infiltrating the home in search of a place to overwinter. Large numbers of ladybugs that gather all over the house are not beneficial, especially when they start falling everywhere- onto food, the bed, or you.
