A common remedial measure consists in cutting out the grub with 

 a sharp knife. This is best done in the fall or very early in the spring.

rough barbs ; the grub or a piece of it will then be drawn out with 

 the wire. 



The best preventive measure consists in drawing up earth around 

 the- base of the tree in early spring, remo\dng it toward the latter part 

 of summer. The moths will not lay eggs on the trunk when this is 

 done. The trunk may be protected with a cyUnder of paper tied 

 around it, extending up 12 or 15 inches and dowTiinto the ground an inch 

 or two. Washes applied to the tree to prevent egg laying are only 

 partly successful.
