18 PARMEKS' BULLETIN 857. 



In Australia very extensive work has been done looking toAvard 

 the destruction of maggots in wool, but nearly all the remedies 

 devised have serious objections, so that dependence must be placed 

 almost entirely upon preventive measures. If sheep become infested, 

 however, the wool should be clipped from about the portions contain- 

 ing the maggots. It is necessary to begin the clipping outside the 

 infested area, so as to avoid driving the maggots back into the un- 

 soiled w^ool and thus extending the trouble. When the maggots have 

 been concentrated in a certain spot by clipping around them, the 

 application of stock dip in concentrated form or the use of chloro- 

 form, especially if the infested area is covered immediately with a 

 piece of oilcloth, will destroy the maggots, and the entire mass then 

 can be clipped off. Mixtures of turpentine and tar have been tried in 

 Australia for the destruction of wool maggots and the prevention of 

 subsequent infestation, with a fair degree of success. It is important 

 that something be applied to deodorize the infested parts and hasten 

 healing. Some sheepmen use air-slaked lime dusted lightly over 

 the parts to dry up the discharge and reduce the odor. This undoubt- 

 edly is accomplished to some extent, but there is some danger of 

 forming crusts and having maggots infest the sore places or wounds 

 beneath these. 



On large sheep ranges, when the lambing is done during seasons 

 which are favorable for infestations, it is best to have the flocks 

 divided into rather small units and carefully watched, so that any 

 fly-blown sheep may receive immediate attention. 



To protect lambs and other sheep during the summer months from 

 being blown by bluebottle flies an effort should be made to prevent 

 diarrhea, and when sheep get dirty they should be promptly trimmed 

 up. Apply to the rump, and to the parts fouled by diarrhea, grease 

 containing a few drops of crude carbolic acid or tar oil. The grease 

 will hold the tarry odor in suspense and act as a fly repellent.
