A mole cricket infestation can be identified by brown patches on the lawn where they have eaten the roots of grass and caused it to die. If the infestation has not yet reached this stage, they can be difficult to spot due to their nocturnal nature, but they can be brought up from their tunnels by mixing 1.5 ounces of dishwashing liquid with two gallons of water. Sprinkling this mixture over a few feet of grass will produce several mole crickets within just a few minutes if the infestation is serious enough to require treatement. Mole crickets can also be a problem on golf courses and on other areas with turf. Their underground tunnels can also stretch to lengths of fifteen or twenty feet.
