Chemical Barriers
Chemical barriers use a non-repellent termiticide in the soil. Termites pass through the treated zone, pick up the active ingredient and die. They can be installed in existing homes by trenching, rodding and drilling. They provide protection for up to 8 years when maintained.
Physical Barriers
Physical barriers — termite shielding, stainless steel mesh, or graded stone — are built into the structure. They do not kill termites but force them into the open to bypass the barrier, making detection easier. They are primarily for new construction and major renovations.
Combining Both
New builds can incorporate physical barriers with a chemical soil treatment for layered protection. Existing homes rely on chemical barriers and monitoring. We recommend the most suitable approach for your construction and stage.
