2 Claims. (01. 21-63)
My invention relates to a device for exter
mination of termites. There are many different
species of termites but this invention is concerned
with dealing with those termites only which may
occasion,serious damage to woodwork of build
ings or to stored articles, including furniture,
books, or other articles of plant origin. The com
mon type of destructive house termite of North
America includes ground-nesting forms that
cannot live without moisture, which they get
from the earth. These termites occur practically
throughout the United States.
The normal habitat of these termites is in
connection with dead wood, old stumps, etc, on
which they feed, and in such locations they may 16
establish large colonies containing queens, wing
Everyyear it costs property owners consider
able sums to replace or repair property which
the worker termites have ruined to provide food
for their colony. '
' l
The way to stop the damage caused by ter
mites and to keepthem from causing damage is
to prevent them from getting into the wood of
buildings as by treating the wood in accordance _‘
with the present invention. It is universally "
agreed that where wood is used, it should be
treated with chemical preservatives to render the
wood more resistant to attack by termites.
It is, therefore, necessary to'impregnate the
Wood with some chemical preservative of which
there are many on the market, but such impreg—
nation must be thorough. It is now the aim of
this invention to provide a device for the pur
less workers, and soldiers. In spring and fall,
males and females, white winged but with black
