GRASSHOPPER CONTROL. aye 
mounted on a wagon (fig. 21) has been used successfully for this 
purpose in the western portions of the country. 
In applying the poisoned-bran bait in orchards, care must be taken 
to avoid distributing it close to the trees, because severe injury to 
fruit trees occasionally results from such applications of arsenical 
poisons. 
Proper time for applying the poisoned baits—The time of day 
chosen for distributing the poisoned baits has an important bearing 
upon the results secured. In 
California and other semiarid 
regions the bait should be dis- 
tributed in late afternoon or 
early evening, just before the 
_ grasshoppers ascend the plants - 
on which they usually pass the 
night. They are apparently 
hungry and thirsty at this 
time and greedily take the 
bait if it be available. In the 
moister portions of the coun- 
try, such as New England and 
Florida, the bait is best ap- 
plied early in the morning in 
order that the best results be

hoppers do not drop dead immediately upon eating the poison, as it 
usually takes from one to five days for the full effect of the baits to 
beceme apparent. 
SUMMARY OF CONTROL MEASURES. 
1. The most important and by far the most practicable means of 
controlling grasshoppers is by the application of the poisoned baits 
described on pages 15 and 16 of this bulletin. A strong effort should 
be made to apply these remedies when the grasshoppers are young, 
thus saving labor and material and therefore money. In the semi- 
arid climates the baits should be applied during the late afternoon 
hours and should have water added to them as mentioned above. 
In moist climates, such as obtain in the Eastern and Southern States, 
the baits may be prepared without the additional water and applied 
during the early morning hours. 
2. Where the topography of the infested fields will permit, the use 
of hopperdozers or other grasshopper traps is sometimes partially 
effective, but these methods are not often wholly satisfactory.
