 The main damage done by mole crickets is as a result of their burrowing activities . As they tunnel through the top few centimetres of soil they push the ground up in little ridges , increasing evaporation of surface moisture , disturbing <unk> seeds and damaging the delicate young roots of seedlings . They are also <unk> to <unk> and pasture @-@ grasses as they feed on the roots of the grasses , leaving the plants prone to drying @-@ out and damage by use .
