If termites can’t get in your home, they can’t cause any damage. That’s why it is a good idea to invest in preventative measures, like physical barriers. Physical termite barriers are just what they sound like – barriers that stop termites from gaining access to your home.
Physical barriers are primarily used to stop subterranean termites. These little guys usually invade a home from below. They dig their way through the soil and attack a home through a crawl space, wood pile, ground floor window ledge or wooden patio. If you can limit your home’s contact with the ground, it will be a lot harder for subterranean termites to invade.
This is exactly what physical barriers are meant to do. If you are building a new home, you can put a concrete slab underneath the house, blocking contact with the soil. Another common physical barrier is a layer of stainless steel mesh that goes between your home and the soil. As with a chemical barrier, physical barriers are not a guaranteed solution against termites. They can, however, make it much harder for termites to reach your home, thus lowering the chances of an infestation.
