Australian homeowners and gardeners alike are dealing with a rather interesting concern: mulch ending up with termites. Whenever termites appear in the mix, nobody quite knows how to go about taking responsibility. Is it the landscape suppliers’ fault or the gardener’s? 

Understandably, they are looking to figure out where termites came from in the first place. Were there already termites in store-bought mulch? Did the mulch delivery serve to attract termites?

If your brickwork has small cracks or gaps in it, termites can enter your home stemming from mulched areas. Do yourself a favour and put mulch under the weep holes by 75mm only. Mulch being laid out over weep holes is a prime trigger for several termite attacks. 

Termites and Mulch: A History

There are several hotspots the world over for termites. Australia is one of them, to the tune of roughly $1B dollars in annual damage to homes. Plenty of new homes have a lot of stumps and ground-up logs that were buried and compacted underground. It’s typically green waste left over from land clearing. The wet, soft, mulchy substances are very attractive to termites since they are able to feed off of them. 

Untreated and decaying timber makes it easier for termites to take in. Natural mulch is available for termites at all times. Termites generally forage within the ground’s initial 30 cm to find decaying timber or food. Mulched areas keep the environment damp and moist, which termites love. In fact, they will end up building hundreds and hundreds of tunnels throughout damp mulch. That’s because termites will always want to find where the moisture of the mulch is coming from in the first place.

Landscape Supply Store Mulch

When you visit a landscape store in search of mulch, you will end up being faced with different types. Make sure that you go through the mulch you select. Put your hands into it, dig and pick through it. From that point, inspect whether you have termites in the just-bought mulch. It’s worth noting that termite-resistant mulch is usually able to stand up to the name/term. In those cases, you probably won’t find any termites. 

If there’s already been an unloading of termite-laden mulch, rake the mulch across the grass! Termites need access to underground tunnels to and from their colony. The moment termites end up exposed to grass and sunlight, ants will eat them almost immediately. If, for some reason, the ants don’t get to them, the termites will die out within 12 to 24 hours.

Needless to say, if the mulch has termites and it’s still in the trailer or the bag, go back to the store. Make sure they take it back in, and get yourself termite-resistant or treated mulch instead.

What Kind of Mulch Resists Termites?

  • Cedar Mulch
  • Cypress Heartwood
  • Tea Tree Mulch
  • Treated Mulch


Termites are a huge problem worldwide, and unfortunately, Australia is one of the hotspots. It’s found in mulch quite often, and mulch attracts termites because of its moisture content. Termites create hundreds of tunnels to find what’s making mulch damp, so finding termites in your mulch is not out of the ordinary. Fortunately, there are ways to get rid of termites when they infiltrate your home, such as calling on pest control services.
