How TO Combat Rabbits, etc. 335 



dry weather, when the ants are activ.^ and when there is no strong wind 

 to blow the powder away. The best time to begin the treatment is wh:n 

 the ants first become active in the spring. Th: application should be 

 repeated at intervals of one week to ten days, as long as ants continue to 

 show up. The poison acts slowly, killing the ants in one to three days. 

 In crawling back and forth across the poison the ants get the fine powder 

 on their hgs and bodies and thus carry it into their nests and track it over 

 their food supply. 



Ants infesting houses ehould be traced to their nests if possible and 

 destroyed by pouring in a small amount of coal oil or carbon bisulphide. 

 Th:se small ants are valuable in grain or seed bins. They destroy the 

 larvae of harmful insects, especially pea and bean Weevils, and grain 

 weevils. 



GRASSHOPPERS 



Grasshoppers are on the whole th? worst, or one of the worst, pests 

 with which the Arizona farmer has to contend. Grasshoppers not only 

 destroy crop-, gardens, and fruit trees, but also do much damage to the 

 range by destroying grass and mesquite bean crops. 



Fig_ 9. — Turkeys are great grasshopper destroyers. They should be herded in order that 

 they niav keep on the move and also that coyotes may not harm them. Herding an hour in the 

 morning" and an hour in the late afternoon and penning for the rest of the day and at night is a 

 good plan to handle them. Some one in the comnnmity co\ild well make a specialty of raising 

 and herding turkevs, or taking them to raise and market on shares, thus doing a large enough 

 business to afford' to devote his time to it. (Note the boy in the background and also how the 

 turkeys string out in a line). 



In communities where these pests appear in large numbers and where 

 the region is sparsely settled, it is difficult and expensive for a farmer who 

 is surrounded by uncultivated land to save much of his crop. However, 

 if active measufes are taken in time grasshoppers can be controlled.
