Chemical Barriers provide a liquid barrier using an approved termicide around the perimeter of the building. Once dried, the chemical bonds to the soil to create a barrier.

There are two types of Chemical Barriers available on the market. Repellent and Non-repellent.


Repellent Chemical Barriers are a cost effective barrier to install and have been around for a long time. They are a trusty type of barrier to have for the right property. The most commonly used repellent chemical is Bifenthrin.

If termites come into contact with this barrier, they will either die or be repelled.

The important factor with this type of barrier is to ensure there are no termites in your house prior to the barrier being installed as it may lock the termites into the building.


This type of barrier is more versatile. They will not lock termites in your home and will destroy a colony via a transfer effect. This happens because the termites do not know they are walking through a chemical so they take the chemical back to the nest.

Why use a Termite Chemical Barrier

Some properties are more suited to Chemical Barriers while some are more suited to a Termite Baiting System. Click here to find out more about Termite Baiting Systems. The factors that determine suitability are access, slope, soil type, and exposure to elements. When we come to inspect your site we will advise you on the best possible solution for your property.

What we do

There are a few methods used for installation of Termite Chemical Barriers, they consist of:

  • Drilling holes through the concrete, injecting the chemical into the holes and capping the holes
  • Trenching down beside the house and treating the soil, it is then backfilled (sometimes the soil may need to be replaced with a more suitable soil)
  • Installing reticulation pipes around the house so it can easily be replenished at future dates
