 In their native lands , mole crickets have natural enemies that keep them under control . This is not the case when they have been accidentally introduced to other parts of the world . In Florida they are considered pests and are described as " a serious problem " . A University of Florida <unk> report suggests that South American Neoscapteriscus mole crickets may have entered the United States at Brunswick , Georgia in ship 's ballast from southern South America around 1899 , but were at that time mistakenly believed to be from the West Indies . One possible remedy is biological pest control using the <unk> wasps Larra bicolor . Another remedy that has been successfully applied is use of the parasitic nematode Steinernema scapterisci . When this is applied in strips across grassland , it spreads throughout the pasture within a few months and not only controls the mole crickets , but remains infective in the soil for future years .
