Termite Control - Physical Barriers

Physical barriers are so-called because they rely on the physical resistance of the material to resist termite attack. These are usually installed during new constructions, but some can be retro-fitted to existing houses.

Barriers can be placed under concrete slabs, foundations and within cavity walls. Hardware and building suppliers may be able to advise on products that are available for DIY.

Physical barriers are made from metal, crushed rock or other materials that termites cannot chew through, and in which any gaps are too small for termites to move through. Most of these products have to be installed by professionals that are licensed by the manufacturers. 

Ant caps are installed at the top of underfloor piers or stumps to force termites into the open where they are easier to detect during regular inspections. Ant caps are not a barrier by themselves.
