Liquid termiticide applications are commonly used as they are versatile, less involved to install and cost effective. Termiticides use suspended concentrates that suspend the active ingredient in water which then used to distribute the product. Once the suspended particle comes in contact with the soil it bonds with the soil thus creates a barrier from the soil.
A Chemical Barrier is a liquid (Termiticide) which is applied to the soil to form a barrier between the soil and the building structure which prevents termites from entering your home. Chemical Barriers can be applied under a concrete floor or around the foundations of the building both prior to or after construction.
