When your lawn looks silvery and wilted in the summer, it might need a treatment that can only be done in winter. A miticide sprayed on the lawn in early winter helps reduce mite populations – and the damage they cause. We perform two applications, the first being in December, and the second in February or March, depending on weather conditions at that time.

Clover mites are extremely small red and green mites often concentrated in grass next to the foundation of a building. They are especially abundant in Colorado when winters are dry and warm.  The pest congregates on the south and west side of buildings and will enter your home between October and May.  Freezing temperatures cause the mites to become dormant but several generations are born during their active period.

Clover mites will damage grass, turning it a silvery color. Once in a building, mites can spread to walls, curtains, furniture and carpet. Although they do not bite, transmit diseases or feed on household furnishings, they can be a nuisance and leave red stains when crushed on surfaces. Winter watering, especially on southwestern exposures, can alleviate mite problems. To keep clover mites from coming inside a building, leave an unplanted, three-foot border around the building.

The eggs of winter mites hatch in October and increase into late winter hatching when soil temperatures drop to 50 o F

[10 o C].  The larval and nymphal stage mites feed by rasping the surface of the grass blades and sucking up the cell contents. The larvae has six legs, while the two nymphal stages are eight-legged but smaller than adults (Tashiro).

It is not unusual to find several thousand mites per square foot. These heavy mite populations diminish in April when eggs are laid on dead grass plants and the adults die. This damage is often mis-diagnosed as winter kill or desiccation. Severe damage is more prevalent during warm winters.

During the winter season it is hard to identify damage that is being done. Normally snow covered grass slows down this process. However with the lack of moisture and high temperatures the mite activity is already high and well on its way.

We have the experience to address this issue and within a few seasons you will see a healthier lawn you desire. We offer a lawn care package that will give you desired results when the plan is followed and proper watering is applied. However, obtaining a healthy lawn starts with controlling the mite population.
