Mix the chemical bug spray with water in the pump sprayer container. Follow the manufacturer's directions to create a solution that is half to one-quarter strength of the bug chemical.
Screw on the top of the pump sprayer. Pump the handle a few times to create pressure in the pump.
Spray around your home's foundation. Cover a 10- to 12-inch space along the soil when spraying; avoid spraying past this distance because then you would be covering the runoff area around your home.
Look for cracks or crevices around your home. Spray these areas to prevent bugs from entering.
Spray behind steps, bushes and other items blocking the ground around your home's foundation.
