As in the case of the majority of mites, it is extremely 

 difficult to eradicate when it has estabh'shed itself in the 

 garden, as it lives beneath the surface of the soil. The 

 safest remedy is to burn the infected bulbs and roast the 

 adjacent earth. If the bulbs are considered to be too 

 valuable to burn, they might be carefully treated with 

 paraffin or kerosine several times at intervals of a week or 

 two. Fumigating in a small chamber with nicotine or 

 hydrocyanic gas at intervals, as the gas will not kill them 

 m the ^gg state, would probably destroy the mites.
