TRAPPING BABY TICKS. 23 



that have gotten on the cattle. The ticks are killed 

 before they have had a chance to make any eggs or 

 suck much blood. 



Then the animals go back to pasture again and 

 trap still more seed ticks. After the animals have 

 been dipped in the medicine every two weeks all 

 spring and summer there will be no more ticks to lay 

 eggs. There will be no more eggs left to hatch out a 

 fresh crop of seed ticks. All the ticks that have been 

 trapped by the cattle have been killed by dipping. 

 All the little seed ticks that did not get on the cattle 

 have starved to death. 



EVERY ANIMAL MUST BE DIPPED. 



' Where the people of a county see that every cow, 

 calf, steer, horse, mule, and colt is dipped regularly 

 during the spring and summer, they will get rid of the 

 ticks in their county in a single year. All the cattle 

 in the county must be dipped. It will not do to dip 

 some cattle and to let others go undipped. The 

 undipped cattle will spread egg-laying ticks along the 

 roads and in the free pastures and woods. The eggs 

 which these ticks lay will hatch into seed ticks that 

 will get on undipped cattle. Those that do not get 

 on cattle during the dipping season may still be alive 

 in the pasture in the fall. They may then get back 

 on the dipped cattle when it is too cold to dip cattle 

 again in the medicine. 



Every cow, steer, or calf that is not dipped in the 

 medicine regularly is liable to carry and spread ticks 

 wherever it goes. As long as there are any ticks alive 

 on any of the cattle the county can not get entirely 

 rid of fever ticks.
