I do not know if among the many things you cultivate you include the growing of potatoes. But if you do I would like to suggest among the remedies for the Colorado beetle the use of kerosene. I do not think it could be used successfully by sprinkling diluted with water: but if some kerosene be carried in a small open vessel, it can be applied by a very small sponge fastened to a stick, or by a drop of the oil from the stick itself; a touch of the oil is fatal to the bug. It is easier than hand picking, and safer than Paris green. In knocking bugs off many fall down and escape, but none escape if touched with the kerosene.
