Termite infestations treatment and prevention in homes

Do you have termites in or around your home?

The home owner can discourage termites by remembering these facts to help you and your home.

    Termites are attracted to wood, so remove potential termite food away from buildings - their food can include timber stacks, old stumps, building refuse, garden decoration such as sleepers and logs
  • Waste timber from construction activities is often left in place or stored under the house – remove all timber formwork
  • Timber can be treated to prevent termite attack, and some timbers are naturally resistant - use treated or naturally resistant timber when it is in contact with, or close to, soil
  • Termites are attracted to water, so fix leaking water pipes, drains, showers, sinks etc, plus capture water from air conditioning units
  • Termites prefer humid conditions, so keep air under the house dry by improving sub-floor ventilation, drainage and access
  • Termites cannot chew through properly laid concrete, so ensure concrete slab is properly designed, compacted, and cured
  • Termite colonies can sometimes be located - it is possible to eliminate colonies by killing the reproductives (the queen and the king).

 

Regular inspections are the most important part of controlling termites before they do any damage. Therefore:

  • arrange regular inspections – at least once a year in cooler areas and twice a year in warmer areas
  • inspect during periods of high termite activity - early spring to late summer is generally the best
  • keep the edges of the house (slabs, foundation, piers and stumps) clear of clutter, including garden beds and vegetation
  • professional pest controllers are trained in inspecting houses for termite activity - use their services
  • home owners can inspect houses themselves more frequently than a professional, if they can identify termite activity.

Chemical Barriers

Chemical barriers are so-called because they rely on a chemical to resist termite attack. The chemicals are usually insecticides. These barriers can be placed under concrete slabs, foundations and around houses.

Chemical barriers can be installed in new and existing structures, but can only be installed by licensed pest controllers.

There are two types of chemical barriers in-soil.

In-soil chemical barriers are formed when the chemical is applied to the soil under or around the foundations of a building.

There are several different chemicals currently registered for use as chemical barriers.

Jae pest only use best of two chemical which is best of all and cost effective.

  • Bifenthrin
  • Fipronil

 

Termite pest management and control

Approved methods of preventative termite control are covered by Australian Standard AS 3660.1 (2000). Remedial termite control is covered by AS 3660.2 (2000). More information is available from Australian Standards, and can be be purchased from their website.

Workers

It is important to remember that house construction is variable. Consider:

  • Wall
    Termite lead
    in sub-floor
    the type of construction (slab on ground, suspended floors, pole etc)
  • the materials used
  • soil types
  • slopes
  • size of house
  • size of block
  • year of construction

Australia is a big and varied country, from cooler temperate climates to wet tropical ones. Such variation is important to remember when considering termite control methods. Should one particular method work well for one house, it may not prove appropriate for a second.

 

Barrier treatments

A remedial chemical soil barrier can be applied under and/or around the house in a similar fashion to a preventative chemical soil barrier.

Chemicals can be applied to the infested area inside the house. This can include liquid formulations or dusts. Liquid formulations are similar to those used in chemical soil barriers.

 

Dusts

Dusts can be applied as stand alone treatments, or as part of a combined approach.

Dusts can only be used by licensed professional pest controllers. The pest controller applies a small amount of dust containing a chemical active ingredient into the wood or area infested by termites (often called the ‘termite workings’).

The dust settles onto the termites, which then carry the dust back to the nest. The termites clean themselves of the dust and ingest the active ingredient. Grooming is a social activity so the active ingredient is spread throughout the colony.

If enough active ingredient is ingested, then it is possible to eliminate the colony.
Active ingredients in dusts include:

  • Arsenic trioxide
  • Fipronil
  • Triflumuron.

 

Baits

Baiting systems concentrate termites into a bait station and then feed the termite a bait – a palatable food containing an active ingredient.

The termites collect the bait, return it the colony, and so spread the active ingredient throughout the colony. If enough active ingredient is ingested, then it is possible to eliminate the colony.

There are commercial baiting systems that have the bait included - these are available only from licensed professional pest controllers.

Bait systems can be applied as stand alone treatments, or as part of a combined approach. Bait systems can form part of the inspection of a house, acting as a continuous monitoring system.

Active ingredients in baits include:

  • arsenic trioxide
  • hexaflumuron
  • noviflumuron
  • chlorfluazuron.
