Post Construction Anti Termite Treatment

Post Construction Anti Termite Treatment And Procedure

Post construction Anti termite treatment is a termite control technique used on a building that is ready for habitation or a residence that has been occupied. This strategy is used when pest intruders enter the building through the surface soil and spread within the structure in search of food. Termites will crawl up from the soil and destroy any wood furniture, doors, wood frames, and other structures.

Anti-termite post-construction in termite-infested structures is the correct step in preventing damage to your building. It is not unheard of that you will have to rebuild your building if termites are permitted to attack consistently throughout the year.


Post-construction termite treatment can be done after the building is constructed and ready to be occupied, or even if the building is already occupied. The floor will be slightly pierced with a drill to allow chemicals to be injected and then covered in nearly the same state as before it was perforated.

  • The termite route that needs to be reinforced is clearly visible.
  • The injection point is cheaper.
  • Workmanship that is cleaner and neater

Preventative measures and precautions for termite treatment

  • The primary purpose of soil treatment is to build a chemical barrier between termites in the soil and the structure to be protected against termite infestation.
  • To treat the soil outside of the foundations, the soil in contact with the building’s outer wall must be treated with a chemical emulsion at a rate of 7.5 L/Sqm. This therapy has to penetrate at least 300 mm.
  • Termites in wall search for holes or cracks in the following locations to crawl through in order to get access to the building:

A). There is a gap at the intersection of the floor and the walls as a result of the concrete shrinking.

B). Cracks emerged on the floor’s surface as a result of structural faults. In the construction and expansion joints of a concrete floor, respectively.

  • Chemical treatment should be utilised whenever cracks are noticed on the bottom level of a building. To do this, drill 12 mm holes vertically down to the soil at 300 mm intervals at the floor/wall junction, construction joints, and expansion joints (as previously specified).
  • The wood is only treated where it comes into contact with other materials. Anti-termite treatment must be used in all places of the building where wood comes into contact with other wood.
  • Drilling 6mm holes at the junction of woodwork and masonry at a downward angle of roughly 45° allows the chemical emulsion of concentration to be sprayed directly at the points of contact with the surrounding masonry.
  • Wall switch boxes and other electrical outlets can be disinfected by removing their protective covers and dusting the insides with a 5% Malathion mixture.

Preparation of the Site

  • The termites may be stored by trees, stumps, logs, or roots on the site, which must be removed.
  • Surface soil is scarified to a depth of 75mm from the top, suggesting areas where chemical treatment penetration is likely to be slow.
  • Pre-moistening of the soil is carried out to fill the capillaries in the case of loose and porous or sandy soils where loss of treatment solution is greater.
  • For flooring treatment, levelling and grading must be done, which must be free of organic material and thoroughly compacted.
  • All woodworking equipment, including as frames, levelling pegs, timber offcuts, and other construction detritus, should be removed from the treatment area.

Steps of anti termite treatment for wood

  • Observation of the construction
  • Treatment of the soil surrounding the foundation
  • Underfloor soil treatment
  • Cavity Filling in Masonry
  • The treatment of woodwork. 

1. Observation of the construction

The goal of the inspection is to determine how much termite was transported into the house, where it came from, and which areas of the building were harmed. 

2. Treatment of the soil surrounding the foundation

  • The soil beneath the foundation and surrounding the building is treated at this stage. 
  • On the outside of the building’s outside wall, a 50 cm-deep hole is created. 
  • Iron rods are used to drill holes in this trench at a distance of 150 mm c/c. 
  • This hole should extend all the way to the top of the footing and be at least 50 cm deep. 
  • The soil is then treated with 1.5 litres of solution per 1 m2 of soil surface area. 

3. Underfloor soil treatment

A 12 mm diameter hole is drilled at a distance of 300 mm c/c where there are fractures in the floor.  This hole is filled with the disinfection solution until the bottom soil is saturated. 

4. Cavity Filling in Masonry

This treatment includes drilling holes of 12 mm diameter at a 45-degree angle on the surface of both sides of the masonry wall at the plinth level at a distance of 300 mm c/c.  In these pores, an anti-termite disinfecting solution is used. 

5. The treatment of woodwork. 

In this treatment, the wood is given a 6 mm diameter hole 130 mm c/c at a 45-degree angle towards the bottom. This hole is filled with an oil-based chemical solution.


Post-construction anti-termite treatment is an important step in assuring a building’s long-term protection and structural integrity. This treatment is used to prevent termite infestations in existing structures once construction is done. Post-construction anti-termite treatment often entails drilling into the foundation, walls, and floors to establish termiticide access points, followed by the injection of these chemicals to create a protective barrier. Furthermore, termiticide should be applied to locations where termites are likely to penetrate, such as plumbing and utility penetrations. Regular inspections and potential treatment reapplication are also part of the maintenance procedure. Finally, post-construction anti-termite treatment is critical for protecting investments, protecting structures, and reducing the danger of termite damage in existing buildings. 


1. What exactly is post-construction anti-termite treatment and why is it required?

Answer – The administration of termiticides in existing structures to avoid termite infestations is known as post-construction anti-termite treatment. It is vital to safeguard structures from termite damage and to maintain their structural integrity.

2. How frequently should anti-termite treatment be conducted after construction?

Answer – The frequency of post-construction anti-termite treatment may vary based on factors such as termiticide kind and termite pressure in the area. Inspections and potential re-treatments are typically needed every 2-5 years.

3. Is post-construction termite control safe for residents and pets?

Answer – The safety of post-construction anti-termite treatment is determined by the products used and how they are applied. Modern termiticides are supposed to be safe when used appropriately, however it is critical to follow the pest management specialists’ safety rules and re occupancy recommendations.

4. Is post-construction anti-termite treatment a do-it-yourself project?

Answer – Post-construction anti-termite treatment often necessitates the use of specialised equipment and skills. It is best to contact licensed pest control specialists that have the knowledge to analyse your individual needs and administer appropriate remedies for home remedy for termites in the wall.
