Clover mites live on or close to the food they like to eat. Once they find a food supply around your home, they will quickly move onto the siding.
Clover mites are tiny, about 1/30 of an inch. That's smaller than a pinhead!
In severe situations, just like this one, clover mites will live in the siding and/or the walls of the house. Fortunately, only a small section of the exterior of the home was infested.
