I am building my house and want to spray the walls for termites. What is the best stuff to buy from Lowes or Home Depot for termites. I have a backpack sprayer so it wont be a big choir for me. The house is dried in and the insulation will be blown into the walls in 4 days and thought this would be a good time to spray all the 2X4s before sheetrock goes up. What is yalls suggestions for a pesticide. I dont have a license so cant buy commercial stuff.
