How to Use a Termite Barrier
One way to prevent termites from invading your home is through the use of a termite barrier. Termite barriers may be made in a mesh design, from rocks, or as a chemical that is placed on the ground around your home to help keep termites away. Although mesh and rock barriers are very efficient and are more environmentally friendly than traditional chemical treatments, their major drawback is that they need to be installed by professionals during construction. If termites get into your home they can cause an enormous amount of damage, eating through the cellulose present in the walls and floors. Termites also attack smaller items, such as books and picture frames. Although a chemical barrier can be implemented yourself, due to the volume of chemicals involved, it is recommended that you consult a professional terminator.
Step 1 – Dig Trench and Drill Holes
Dig a trench round the exterior of the house to a depth that exposes the foundations and apron of the concrete foundation slab. Care must be taken around any utility pipes. It is essential to dig right down to the base level of all incoming utility pipes, as they will provide an entry point for the termites if not thoroughly treated. Drill holes at regular distances around the concrete apron to inject chemicals into.
Step 2 – Distribute Chemicals
Wear protective clothing when dealing with the chemicals. A full protective suit is recommended, but at the very least, you should wear gloves, goggles and a mask. Pour the chemicals into the holes in the concrete to infuse the soil. Ensure that chemicals are correctly mixed or diluted according to manufacturer specifications
Next, use the garden spray (one with a high capacity that fits on your back is best) to soak all of the soil surrounding the foundations with the chemicals. Make sure that no gaps are left for the termites to exploit. Termites can fit through a gap the width of a pencil lead so if you have to refill the garden spray, make sure that you overlap the last area sprayed when you continue. It is better to spend more money on additional chemicals than have to treat your home for a termite infestation.
Step 3 – Cap or Refill Concrete
Fill in the holes in the concrete or insert caps over them. Buying caps will be slightly more expensive than concrete but will allow easier access when topping off the chemicals on future occasions. You should find that fresh chemicals will be required in around 5 years time.
Step 4 – Fill Trench and Monitor
Once all of the chemicals have been applied, the trench should be filled in. Regular monitoring for termite tracks on the soil surface should be carried out. Many professional companies will include a monitoring program in their installation package for a termite barrier, or you can set up an agreement once you have installed the barrier yourself. Installing termite baiting stations at intervals around your home as an early warning system against possible infestation is another feature that you may wish to consider.
