Remedies. It is manifestly impossible to attem.pt to control this 

 insect on other than valuable trees, and in such situations, digging 

 out the borers, with possibly recourse to the use of repellent washes 

 described on page 29, is about all that can be done and in the majority 

 of instances should afford considerable protection.
