The sound, produced only by adult males, is generated when by rubbing one wing against the other. They use the sound for locating mates, to signal danger or to indicate their presence.
Sanitation is an important means of reducing cricket feeding and breeding sites.
Eliminate weeds and dense vegetation around the foundation and keep piles of bricks, stones, firewood and other debris away from the exterior of the house. Close all openings to the house and tighten screens, windows and doors. For one or a few crickets in the house, insecticides will not be very useful. Find the occasional cricket and chase it outside, crush it or pick it up with a vacuum. You can spray it directly with an aerosol spray once you find its hiding place.
