Chemical Barriers Frequently Asked Questions



We have compiled a list of the most frequently asked questions we get asked by customers considering chemical barrier protection.

Q: What is a Chemical Barrier?


A: A chemical barrier (also referred to as a perimeter soil treatment) is quite literally a chemical barrier around your home. Termiticide is injected into the soil surrounding your home to create a protected zone.

Q: How does a chemical barrier work?

A: When installing a chemical barrier you have the choice of either Termidor or Altriset. In some cases our qualified technician will recommend a particular termiticide that best suits your needs, otherwise it is a matter of personal choice. Both chemicals work in a similar way as they are both non-repellent termiticides meaning unlike a repellent termiticide, termites are unaware of the treatment and unknowingly pass through the treated area and pick up the chemical, which they then transfer on to other termites, eradicating the entire colony.

Repellent termiticides will repel termites and kill them when they come into contact with the treated area. It sounds good in theory but chemical barriers using repellent termiticides don’t eradicate the colony causing a high level of pressure on the chemical barrier and the termites will eventually find a weak point and once they do, they have an all access pass to your home.

Q: What does installing a chemical barrier involve?

A: Our technicians will dig a trench along the exterior walls of the home and flood the trench with your chosen termiticide before replacing the soil. Most houses have concrete pathways or patio areas right up against the slab; in these cases we remove pavers (if and when we can) and drill holes 200mm to 300mm apart along the external perimeter and inject your chosen termiticide into the soil beneath. We then fill the drill holes with colour matched mortar and replace any pavers we have lifted. As you can see, after Results Home Services has finished installing a chemical barrier you can barely tell where we have drilled and our technicians take great pride in their work and will always go the extra mile to preserve the look of

your concrete.



Q: I don’t have termites. Do I need a chemical barrier?

A: Yes. We get this question a lot and our response is: how lucky do you feel? As no home insurance covers termite damage, having a chemical barrier as a preventative measure is in itself a form of insurance.

Unfortunately with termites, whilst there are risk factors that make a termite attack more likely, there is no way to know whether termites will target your home. All you can do is be prepared for when they do.

For most of us, a house is our greatest asset, so why leave the safety of that asset up to chance? You wouldn’t drive around without car insurance, so why take the risk with your home?

Q: Are all termiticides the same?

A: No. As previously discussed there are repellent and non repellent termiticides, always go with a non-repellent termiticide as it is a far superior means of termite protection. At Results Home Services we only use the best and latest technology which is why we only work with Termidor or Altriset when installing a barrier. Both are leading the way in termite treatment and management.



You may find a pest controller offering to install a chemical barrier for a price that is almost too good to be true; that’s because it probably is. When it comes to chemical barriers it really is a case of you get what you pay for. So when you are looking at quotes you should always ask the pest controller what termiticide they will be using. There are a number of generic Termidor “knock offs” available so if your pest controller says they’ll use something like Termidor only cheaper, seek out other quotes. If they are willing to compromise on the chemical that will be protecting your home, what else will they “compromise” on?

Q: Is there a warranty on a chemical barrier?

A: Yes. Your chemical barrier carries a 5 year warranty subject to annual inspections. Some termiticide manufacturers will state their chemical lasts in the soil for up to 8 years; however, the misconception is that it carries a warranty for up to 8 years. In actual fact the fine print states it is up to the installer to warranty the chemical barrier according to local climatic and environmental conditions. Environmental factors like rainfall, heat and moisture causes the soil and any chemical present in the soil to degrade. Naturally, in Queensland as there is more moisture and heat present, the soil degrades at a faster rate than perhaps Tasmania which is why insurance companies will only insure a chemical barrier for 5 years in Queensland.

There are some pest controllers offering an 8 year warranty on a chemical barrier. The question to ask here is whether they have insurance to cover the eight years and the answer with be a definite no. No insurer will cover a chemical barrier past 5 years. So you have to wonder why a pest controller would offer an 8 year warranty when neither their insurer nor the manufacturer is willing to.

Q: What payment options are available?

A: We accept cash, cheque or credit card.


We realise that most households don’t budget for a termite attack, so we have teamed up with Certegy Ezi-Pay and are able to offer 12 month, interest-free payment plans for chemical barrier treatments. Ezi-Pay has simple payment options which fit most household budgets. It provides peace of mind knowing your home (and greatest asset) is immediately protected from termites.
