- Termites are social insects living in colonies comprised of a king and a queen (wingless adults or nymphs, depending on the species), and oldiers.
- The king and queen perform the reproductive functions of the colony maintenance.
- The soldiers defend the colony.
- These individuals, separated by division of labor, are referred to as castes.
- Termites feed on wood or wood products, and their digestive tracts contain microorganisms which enable them to convert the cellulose in wood into usable food.
Termites vs Ants
- Termites are often confused with ants.
- The termite has straight beadlike antennae, while those ants are elbowed.
- The abdomen of termite is broadly joined to the thorax (no waist), while the ant’s thorax and abdomen are joined pedicel (wasp waist).
- Termite wings, both the front and the hind wings, are of the ant are considerably larger the posterior wings.
1. Residual Spraying
- Residual spraying with termiticide which act as a stomach and contact poison is apply with a liquid dilution of Premise along the foundation walls of your home to create a continuous treatment zone.
- Termite mound is destroyed by pouring solution of termiticide into the mound after breaking open the structure.
- To facilitate good penetration, holes are made using crowbars.
3. Pre-Construction, Anti-Termite Soil Treatment (ATST)
- A traditional method for preventing subterranean termites from entering buildings within the first 5 to 10 years following construction.
- The objective of applying a termiticide to soil is to provide an unbroken chemical barrier between the wood in the structure and termite colonies in the soil.
- Thus, the insecticide must be applied thoroughly and uniformly to block all routes of termite entry.
- Effective termite control usually requires specialized equipment and often 150 or more gallons of prepared termiticide solution per house, depending on size, basement, etc.
- The most recent termiticides to be marketed are non-repellent to termites, but show delayed toxicity as termites forage through treated soil, which they do not avoid.
- As termites penetrate the treated zone, they contact the active ingredient, which causes delayed mortality and also possibly allows the termites to be overcome by lethal microbes.
- Furthermore, the toxicant is thought to be passed to nest mates through grooming activities and social food exchange (trophallaxis).
4. Post-Construction, Anti-Termite Soil Treatment (ATST)
- Holes are drilled along the perimeter of the building and termiticide will be pumped in.
- The objective of this is to establish a termiticide barrier to prevent termites from entering the structures.
- The distance between two holes is an extremely crucial factor to ensure a continuous chemical barrier beneath the house upon application.
- If the distance between the holes is too wide apart, a gap will be present and this will allow termites to move up into the house.
- Distance between two holes varies between 30 to 65cm.
- Distance between holes to wall perimeter varies between 5 to 20cm.
- A termite bait is usually a paper-, cardboard-, or sawdust-like material containing the active ingredient (or AI) that kills termites.
- The bait is kept inside a plastic bait station. As termites feed on the bait, the termite-killing AI gets into their bodies.
- The AI is spread through the colony as the termites feed each other. As more workers feed on the bait, more AI gets into the colony.
- Eventually the amount of AI in each termite increases until it kills them and the colony dies or is reduced.
- There are two types of bait stations: above-ground and in-ground
- Above-ground stations are installed directly over shelter tubes or infested wood so that termites can begin to feed immediately on the bait.
- In-ground stations are placed in the soil.
- Most stations are cylindrical tubes with disk tops. The disks makes the stations easier to find and keeps them from sinking into the ground.
- The tubes have numerous holes or slits through which termites enter to get to the wood and bait inside.
