Be sure to seal cracks and gaps or other points of entry with caulking compound, putty and weather stripping around foundations, windows and doors. Use tight-fitting screens on windows and doors. It is often difficult to control large numbers of clover mites indoors. Use a vacuum cleaner with proper attachments to effectively collect live mites without crushing them. Dispose of the sweeper bag after collection by burning or taking to a garbage disposal far from the house.
Mites can escape from the bag in the sweeper.
It is best to use a perimeter spray barrier around the outside of the house during the mite invasion period. Outdoors, spray the foundation, exterior walls up to the bottom of the first floor windows, and a strip 10 to 20 feet wide from the foundation out into the grass. Spray the foundation and walls to point of runoff and the vegetation until it is thoroughly wet, which usually requires two to four gallons per 1,000 square feet, depending on the vegetation height and density. Materials labeled for this use include chlorpyrifos, cyfluthrin, diazinon, propoxur and pyrethrins. Indoors, mites can be eliminated with aerosol or contact sprays of pyrethrins.
