Termites can wreak havoc on our buildings if left unchecked. This is especially true in warmer areas of the country such as Queensland, where termite infestations can be a much more serious issue than in New South Wales or Victoria. The history of termite protection  in the country is long, shaping the way we’ve managed the land and designed our homes throughout time.

The Queenslander

Unbeknownst to many, termites have had a big imprint on Australian architecture. Older Queenslander style houses were built to aid termite protection by raising the floor above the ground on stumps made of termite resistant material. This was before chemical pesticides were in wide use during the 1950’s.

Steel caps were placed over the stumps so the termites had to create large mud structures over the caps before they could reach the timber part of the property. With the house raised, you could easily inspect for signs of termites. Homeowners regularly poured sump oil around the base of the stumps to deter termite activity.

Slab On Ground Houses and Organic Chloride

By the early 1960’s, new pesticides came into wide practice that made it possible to build houses with concrete slabs poured on top of a layer of pesticide. The chemicals in these pesticides were called organic chloride and would crystallise in the soil structure, preventing termite infestation and working as an effective termite barrier over a long period of time. New slab on ground style homes became widely popular for their style as well as being easier, faster and cheaper to build.


Dangers of Organic Chlorides Uncovered

During the 70’s and 80’s, research began emerging that outlined the harmful side effects of organic chloride on humans and the environment. As a result, a widespread phase out across all industries gradually took place, from agriculture to construction. By 1995, buildings were no longer protected by organic chlorides meaning homes had no termite protection and were once again under threat from termites.


New Methods for Treating Termites

Over time, new chemical treatments have been discovered to prevent and destroy termite infestations. Underslab spraying continued with new chemicals including synthetic pyrethroids such as bifenthrin or organophosphates such as chlorpyrifos. These chemicals have a relatively short life expectancy, compared to organic chlorides, minimising their environmental impact.

Poor application practices of the new products during the 90’s left many buildings under protected. While termite treatments have improved since then and are highly reliable today, they’re still not as effective as the older ones. Some builders have opted for new construction approaches to protect homes, such as the monolithic slab design. This involves building a thicker and wider slab so termites can’t reach the actual building without creating extensive mud tunnels.
