When it comes to stopping subterranean termites, you have several methods at your disposal, and two of the most popular methods available are the physical and the chemical barrier. Let’s take a look at these two barrier types, their pros and cons, and the differences between them.
The physical barrier
Physical barriers are just what they sound like. They are installed as the home is being built, and they extend underground, creating an impenetrable barrier that stops subterranean termites from building tunnels from their colony to the home. They can last and be effective for more than 50 years, so if you buy a home with a physical barrier, you never have to worry about subterranean termite infestations. However, the main drawback of this type of barrier is that it can only be installed during construction. After the home is built, there is no option to have this barrier installed.
The chemical barrier
Chemical barriers are insecticides that are injected into a trench around the home, and these insecticides seep deep into the earth, creating a barrier that is deadly to any termites that come into contact with it. Chemical barriers have the advantage that they are relatively easy to install, and they can be used to stop an infestation dead in its tracks. Their main disadvantage, when compared to physical barriers, is that they do not last as long, but they still have an 8 year lifespan on average. They can also be installed after the home has been constructed.
Which is best for your situation?
If you are not building a new home, your only option will be to go with the chemical barrier. However, there are other treatment options available against subterranean termites which you may have to consider. For example, you have the baiting station.
Chemical and physical barriers only stop termites from reaching the home, but they do not destroy their colonies. This means that the colony will remain somewhere on or near your property, and the termites may infest other wood in the area, such as fences, firewood, or sheds. This is where the baiting system comes in. It is designed to slowly poison a colony over a period of months, leading to its destruction.
