Why Do Termites Eat Wood?

The main element regarding “what do termites eat” and their preferred diet of wood or grass. 

Termite colonies feed on this natural substance because it contains cellulose – which is a dense carbohydrate that contains the energy they need. Because of a unique symbiotic relationship with gut bacteria, termites can break down and absorb these nutrients. 

But that’s not the end of it: the termites then use digested wood to build tunnels and chambers in their colonies that are unique to the species.

Essentially, termites make their homes out of the wood they’re consuming. So unlike other household pests, you’re likely to find a termite colony made from the very wood they’re destroying. And that’s why the damage can sometimes be so hard to find – as it’s all happening inside a wooden fixture, leaving a hollow exterior that can cost thousands of dollars to fix if left untreated or unnoticed.

Do termites eat hardwood?

Yes – termites will happily feast on the hardwood used to construct your wooden flooring, frame work, bannisters, fences and many other timbers used in the construction of your home. If your house features a lot of hardwood, then you have a genuine risk of termites making themselves at home, which can cause serious structural damage to your property.

Do termites eat treated pine?

Termites are pretty determined creatures, and they can chew through plastic and in spaces lacking chemical treatments on most woods. But in general, treated pine is much less susceptible to termite infestation than hardwood. That’s why we highly recommend making sure pine has been treated by a professional to ensure even coverage.

What other wood do termites eat?

Those worth a special mention are the timbers commonly used in Australian building construction. You’ll be more likely to find termite damage in structures and wooden furniture made from these wood varieties.

  • Radiata pine
  • Tassie oak (Victoria or Tasmanian ash)
  • OB hardwoods (a mix of eucalyptus hardwoods, such a obliqua and messmate)
  • Oregon (one of their favourites)
  • Meranti

Can Termites Eat Concrete?

Finally – something termites can’t eat! 

Concrete provides no nutritional value for termites, so it’s not on their menu. However, they will still crawl through existing tiny gaps in concrete in search of their next meal. So, although spotting termite or termite colonies crawling through concrete in your home might not be cause for immediate concern, there is a strong possibility they’re heading to some tasty wood elsewhere, and it might be worth calling in the experts for a thorough property inspection.

Is There Any Wood That Termites Don’t Eat?

Don’t be put off from having any wooden furniture, ornaments or decoration in your home whatsoever simply because of the risk of termites. Most modern termite management can protect a home to a very high degree.

But, to save the hassle altogether, is there any wood safe from termites?

Is There Any Wood That Termites Don’t Eat?

Common timbers used in Australian construction

  • Merbu
  • Cypress pine
  • Baltic pine
  • Cedar

These timbers are ‘resistant’ to termites in the sense that they are not heavily susceptible to termite damage. However, structures  made from these timbers can still be damaged by other pests that look like termites, as well as termites themselves, so it’s always recommended to call in for a semi-regular termite inspection.
