AND OTHER INJURIOUS INSECTS OF I907 AND I908. 1 47 



"We have found S. vcnustum fairly abundant and annoying stock 

 in this state about Ihe last of May (27th to 30th)." 



Remedies : For present use the various compounds usually re- 

 sorted to. Personal experience leads us to regard oil of citronella un- 

 diluted as excellent as long as the skin is kept moist with same. Ani- 

 mals with rough hair, i.e., winter coat not shed, suffer more than 

 those whose skin is smooth. Horses and cattle in darkened stables are 

 not attacked. For a working team in the field fish oil ( or fish oil three 

 parts and kerosene one part) is a good repellant, applied about once 

 a day. Do not use machine oil. Cheese cloth screens arc effective. 



The Long Meadow Gun Club, at their grounds on the Minnesota 

 River, lost, in the spring of 1908, nearly two hundred young ducklings 

 within three weeks, apparently from the attacks of this pest, for when 

 the duck runs were screened in completely by the use of cheese cloth 

 the mortality was much less. 



In using oil of citronella care must be taken not to allow it to 

 touch the eves.
