They are rusty brown to dark red, soft, oval, and flattened from top to bottom. Clover mites are harmless. They are an annoyance and nuisance because of their presence and tremendous numbers. Clover mites reproduce outdoors. Every mite seen indoors has wandered in from outside.
Clover mites are plant feeders only.
They feed on sap from grasses and clover, and are especially numerous in lawns with a heavy growth of succulent, well-fertilized grass. They do not cause any apparent harm to turfgrass. The traditional control for clover mites is to apply an insecticide spray as a chemical barrier around the house. Spray the foundation, the crevice between the foundation and the ground and the lawn for a distance of 6 to 10 feet out from the foundation. Successful chemical control requires a very thorough treatment.
