Fig. 12—Treatment of basement floors for the control of termites vary with the type of floor. 
In concrete floors, holes should be made with a star drill every 2 or 3 feet along the foundation 
walls, around the heating unit, and at the base of door frames and step runners. Termitgas 
should then be applied through the holes to the soil beneath. After this, the holes should be filled 
with cement. 

Where Hardwood floors are laid over concrete the best way to treat such 
infestation is to remove some of the flooring ONLY where infestation is evident— 
examine the walls for termite tubes, and if present apply Termitgas (with a 
mechanic’s oil can) along the cracks down into the ground. The soil must then 
be treated with Termitgas. (Either by the trench method, or using a star drill 
as already described.) Where wood flooring is badly damaged, replacement is 
necessary. Your good judgment plus our Termitgas should solve this problem.
