What Is An Over-Wintering Pest?

An over-wintering pest is a insect that does not die off in the winter time.  These insects will seek out a crack, void or hollow to ride out the winter cold.  Most of these over-wintering pests will find these places to hide out in the wild but unfortunately some of these insects happen to find our homes as inviting as we do. Over-wintering pests that are most commonly found in the St. Louis area are the Boxelder Bug, Asian Lady Beetle, Cluster Fly and Wasps.  These insects most commonly congregate on the sunny side of the house.  The reason they choose the sunny side is that the winter sun will heat up the wall void to give them some warmth.  Once the insects have gain entry into your home they can become a nuisance all winter as they will become active during warmer winter days.  The insects, once active, will go to the first sign of light.  The bad news for us homeowners is that the first light they see first may be coming from the inside and not the outside.  When this occurs, you will find dead (sometimes alive) on your inside window sills.
