Ladybugs are pretty cute as far as insects go, and they are actually beneficial to have around.  They are sometimes referred to as “natural pest control”; they feed on garden pests like aphids and spider mites.  Humans and ladybugs generally have a good working relationship.  They don’t bother us, we don’t bother them.  Come autumn, ladybugs seek for shelter from the cold.  That is all well and good, unless they want to share our shelter with us.  One or two ladybugs indoors is nothing to worry about, but when you don’t have enough fingers to count all the ladybugs in your house, you may have an issue.  The ladybugs will not cause any harm, but they may be a nuisance.  To prevent ladybugs from seeking shelter in the walls of your home, have your house treated regularly.  They stay out, you stay in, and everybody wins.
