One of the fastest ways to stop an infestation in its tracks is with the use of a termite barrier. Not only that, but termite barriers also offer long term protection against future infestations. Let’s take a look at the two different types of termite barriers out there.

What is a termite chemical barrier?

The most commonly used termite barrier is the chemical barrier. This type of barrier comes with numerous benefits, including a relatively low cost and ease of installation. It is usually installed by a pro, who will dig a trench around the home, and inject termiticides into that trench. The termiticide penetrates the ground around the home deeply, effectively creating an impenetrable barrier that stops subterranean termite in their tracks. Once installed, the chemical barrier will protect the home for up to 8 years.

A chemical barrier puts a stop to an infestation almost immediately. The termites that are already in the home will die shortly after the barrier has been installed, and the termites that are back in the colony will no longer be able to reach the building. However, the main drawbacks of this barrier are that it does not kill the colony responsible for the infestation,and the surviving colony can infest other areas of the property. On top of that, the chemical barrier only protects against subterranean termites. Drywood and dampwood termite infestations can still occur after a barrier has been installed.

What is a termite physical barrier?

The termite physical barrier is composed of concrete, sand, basaltic, or stainless steel mesh structures that are inserted in the ground surrounding the home. These barriers are much longer lasting, but they have the disadvantage of being more expensive, harder to install, and in most situations, they can only be installed as the home is constructed. If the home is already built, usually a chemical barrier will be recommended. They also have the same drawbacks as chemical barriers – they do not kill the colonies, and they do not protect against drywood and dampwood termite infestations.

Barriers are one of the several methods available when dealing with a termite infestation. Baiting systems are another option, and these systems are used to kill off entire colonies. However, they take a long time to do it, so they do have their own drawbacks.
