Because bots may reach the 

 digestive tract of horses throughout 

 the fly season, and for several 

 months afterward, the best control 

 of bots by drugs is by giving treat- 

 ments at intervals during the fly 

 season and at least once during the 

 following winter. 



In general, drugs should be ad- 

 ministered to horses under veterin- 

 ary supervision. However, if pro- 

 prietary products are used, the man- 

 ufacturer's directions on the labels 

 should be followed carefully. 



COMMUNITY CONTROL 

 PROGRAMS 



A number of communities have 

 attempted bot control by a system- 

 atic treatment of all donkeys, mules, 

 horses, and colts. In only 1 year, 

 such treatment has greatly de- 

 creased the annoyance from bot 

 flies and has improved the health of 

 the animals. 



It appears possible to achieve a 

 high degree of control of bot flies 

 by 2 or 3 years of systematic com- 

 munity effort. 



To arrange for a community con- 

 trol program, consult your county 

 agent, farm advisor, or veterinarian. 



PRECAUTION 



Insecticides used improperly can 

 be injurious to man, animals, and 

 plants. Follow the directions and 

 heed all precautions on the labels. 



Store insecticides in original con- 

 tainers under lock and key — out of 

 the reach of children and animals — 

 and away from food and feed. 



Apply insecticides so that they do 

 not endanger humans, livestock, 

 crops, beneficial insects, fish, and 

 wildlife. 



After handling insecticides do not 

 eat or smoke or drink until you have 

 washed. In case an insecticide is 

 swallowed or gets in the eyes, follow 

 the first aid treatment given on the 

 label, and get prompt medical atten- 

 tion. If an insecticide is spilled on 

 your skin or clothing, remove cloth- 

 ing immediately and wash skin 

 thoroughly. 



Dispose of empty insecticide con- 

 tainers promptly. Have them buried 

 at a sanitary land-fill, or crush and 

 bury them in a level, isolated place.
