Spider mites are commonly found in mid to late summer. They thrive in the heat and put a lot of stress on the host plant. We commonly find them in Dwarf Alberta Spruces, Blue Spruces, Junipers, fitzers, Tams, and other assorted conifers and evergreens. Spider mites can devastate a plant because they attack in the heat of summer–when the plant is most vulnerable.
Spider mites suck the plant juices resulting in mottling of the leaves and sickly looking growth. When the initial infestation occurs, fine webbing appears on new growth. Eventually leaves turn brown and drop off. They are generally found indoors, but are more common outdoors during the summer months when the weather is hot.
Symptoms of a mite infestation are lack of plant vigor, and needles turning brown and falling off. Mites often first appear where the host plants are exposed to afternoon sun or where in close proximity to a heat-absorbing surface such as brick or stucco.
