A Biased View of Termite Control For New Construction
Reproductives that are darker in colour to other castes, have functional eyes and strong skin. This caste becomes the leaders of colonies.
The temperature, food grade, and activity of this colony will determine how long it takes to get a termite.
Nests and tunnels are stored moist because worker termites cannot stand low humidity for long periods of time. The temperature within the nursery of a large nest ranges between 10 C and 35 C but varies more than one degree a day. The relative humidity is approximately 100 per cent.
It is important to identify the type of pest termite before beginning treatment. This can help you understand the customs of the colony, find the nest and indicate the most appropriate method of control.
Not known Facts About Termite Control For House
Species are identified with their own soldier termites, which has got the most prominent features.
These termites are commonly dispersed throughout Victoria, and are responsible for more than 80 per cent of termite damage to buildings.
Coptotermes build nests in trees (preferring eucalypts), stumps, under concrete flooring, in wall cracks or enclosed verandahs.
The Main Principles Of Termite Control For New Construction
These termites travel at least 50 metres in the colony using a series of underground tunnels to find food. Coptotermes acinaciformis send large numbers to new food sources and, therefore, respond strongly to bait. In contrast, Coptotermes frenchi research widely for new food resources and feed at points.
Nasutitermes exitiosus is common north of the Great Dividing Range. They construct dim, thin-walled mound nests between 30 cm and 75 cm above ground. These mounds are around 1m in diameter.
This is Victorias largest species of termite called termite. They are normally found nesting in massive pieces of timber (particularly older trees) and are most common in wet, mountainous areas. They may, however, also be found in the foothills of Melbourne.
The Basic Principles Of Termite Control For New Construction
Porotermes tend to reside in smaller colonies than other species, and do not construct shelter tubes or travel far underground. They are more easily controlled than other species.
A mature colony of Schedorhinotermes will have two distinct sizes of soldiers, referred to as major and minor soldiers. Important soldiers grow around 5.6 mm long, while minor soldiers are only 3.6 mm long. The two kinds of soldier have mandibles.
Schedorhinotermes are harmful and relatively nomadic, rather than maintaining a fixed, central nest.
About Termite Control For Lawns
Heterotermes are widely dispersed throughout Australia. They are only a pest species in the Northern Hemisphere.
The soldiers of this species are around 4.75 mm long, with lengthy, dark jaws and parallel-sided heads.
Heterotermes live in tiny colonies which attack fence posts, wood flooring, and paling fences within a small radius of the nest. They are commonly found because they feed on small timbers on the ground surface.
Dusts work to control termites since they ingest and distribute the insecticide among the colony during habitual grooming.
Termite Control For House Can Be Fun For Everyone
Insect growth-regulator dusts (such as Triflumuron) and non-repellent termiticides are the most powerful methods of termite dust control for the human consumer.
Arsenic trioxide dust has been used since the 1930s to control termites, often with the addition of oxide or another colourant. However, arsenic trioxide is a poisonous, highly toxic elemental pesticide that does not degrade.

Baiting is often the ideal way to kill an attacking colony when the main nest website cannot be found. Bait stations also allow you to collect samples of termites for species identification.
Bait stations consist of containers of cellulose materials like timber, paper or cellulose gel that are either buried in the ground near the building under attack or carefully placed inside near known harm.
Bait generally use slow-acting, non-detectable toxins in order that the nearly whole colony can be poisoned before adverse impacts appear. Repellent termiticide formulations like those of pyrethroids are not as colony control agents. Care has to be taken not to cross contaminate baits with even tiny residues of pesticides.
Baiting does not supply a barrier. The baits do not isolate the building since termites are still able to get the structure. For long-term structural protection, barriers are preferred.
The 20-Second Trick For Termite Control For House
Chemical barriers work by applying an unbroken boundary of pesticide around the outside of an infested structure. This makes a zone or band of soil that is poisonous that the termites cannot cross. Creating an effective chemical barrier could involve trenching around the foundations of the construction, and you can try this out injecting the chemical into the soil through holes drilled in concrete foundations.
