Clover Mites (picture), Brick Mites and Spider Mites are just a few of the concerning specimen which tend to infest on a large scale in the early spring and late fall. Mites tend to be very small. However, Brick Mites can grow to 1/8 inch in size and are very visible. Typically applications around the perimeter of a building and locating any gravel, new foliage, cracks in window grouts and green fungus growing between patio or sidewalk stones should be treated as well. Given that these areas provide food, water, and harborage the most effective approach is to eliminate them. Once this is achieved a steady decline will occur and in most cases a solid application in the spring will provide ample results later on in the fall.
