BORING IN THE TRUNK 239 
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, removing 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 cylinder of paper tied 
around it, extending up 12 or 15 inches and down into the ground an inch 
or two. Washes applied to the tree to prevent egg laying are only 
partly successful.
