Termites can wreak havoc on the foundation and framework of your home. Simple soil treatments can be effective for a limited amount of time, but will deplete over the course of weather and soil changes. If you own a house predominately made of wood, and especially if you have a large wood deck, you should chemically treat the lumber prior to building. Chemical treatments are available at many home and garden stores and the application process only takes a couple of days.
Purchase a borax-based chemical treatment solution, such as Boracare (generic Borada LP) or Timbor (generic Borada D). These solutions are available at most home and garden supply stores.
Read the instructions carefully on the bottle of solution. Ensure that you wear the appropriate safety equipment such as gloves, mask and safety glasses.
Apply the solution over the entire surface of the wood, using a paintbrush, or a garden hose spray adapter if you've purchased a type of solution that can be mixed with water.
Allow the wood to dry for 24 hours; then apply a second application for added termite protection.
