Colorado Spider Mites



  • On aspens small black recessed spots or sections on the leaf appear and the leaf eventually drops
  • Dead branches in junipers
  • Blighted and dead patches on lawns typically on the south side in hot dry conditions

These extremely small pests can cause extreme damage to lawns, shrubs and trees. Typically, hot dry conditions and a mild winter can cause spider mites to flourish and spike in population. These pests can rapidly increase in population due to a female that can lay up to 12 eggs a day and a short gestation period of a week. Mites over winter as adults and in early spring they begin to increase in population and if there are enough present they may defoliate a tree, kill branches on shrubs or completely kill sections of turf. We are able to effectively control mites by applying a miticide to trees lawns and shrubs when mites are present. A magnifying device must be used to typically see most mites. Mites range in color from light colored with 2 spots on their back to bright red. Using a white piece of paper and knocking the infested leaf, branch or grass against it is the easiest way to determine if they are present.
