Remedial Measures. — Three methods of control are practiced : 
rotation of crops, fall plowing, and poisoned baits. Cropping for 
two years with some vegetable which is virtually immune, such as 
beans, peas, spinach, cucumber, melon, rhubarb, lettuce, or pepper, 
should rid the soil of wireworms.* 
Fig. 38. Wireworm, Limonius confnsus, adult beetle. Length 
about three-sixteenths inch. 
Late summer or fall plowing is frequently resorted to in order 
to destroy the pupae and beetles. The land should be cultivated thor- 
oly several times in the fall. 
Trapping the adults by poisoned baits is a method sometimes used 
in the eastern states. Sliced potatoes, wads of green clover, or corn- 
meal dough, poisoned with Paris green, have been found effective. t 
These baits should be placed under boards in various parts of 
the field, and renewed once or twice a week during the spring and 
early summer. 
*This list is given on the authority of those who have reported these plants 
to be practically uninjured by wireworms, even when the latter are present in the 
soil. 
tOur own experiments the past year with poisoned baits for this insect 
•were not sufificiently effective to pay for the labor and materials.
