East Cooper residents have several options when it comes to protecting their homes from subterranean termites. There are different factors that may contribute to selecting the best treatment for your home. The foundation type, age, environment, soil type, and grade around your home should be be considered. You will also want to decide if a residual or non-residual quality is important to you. The three types of treatments that homeowners normally have to select from are liquid, baits, and surface or borate treatments.
A liquid treatment would require the soil that touches every part of the foundation wall to be treated. The liquid would also be injected into any hollow block walls, block piers, dirt filled porches, and brick veneer that may be an entry point for termites. The soil below slabs touching the foundation and expansion joints would also be treated. Treating the soil below slabs and in block voids would require these areas to be drilled. A small hole that is roughly 1/2″ in diameter is drilled and then the liquid is applied. These holes are then plugged and sealed with mortar. The length of time a termiticide treatment remains effective around a structure depends on thoroughness of the application, termite foraging intensity, conducive conditions and environmental conditions. Liquid treatments can be applied as a repellent or non-repellant. A non-repellant treatment allows the termites to forage through the material without it being detected. It usually has a slower effect on actually killing the termites and may eliminate more of the colony. Liquid treatments tend to have residual qualities. They remain in the soil providing protection for a number of years.
Bait treatments usually involve the installation of stations around the perimeter of the home. The stations are generally located approximately 2-3 ft. away from the foundation and about 10-15 ft. apart.The bait stations usually contain a material made of cellulose or wood. They may contain a bait that remains in the station for several months. The stations are usually monitored every 120 days. Some baiting products are now labeled to be monitored once a year. Baits are also considered non-repellents and over time may eliminate more of the colony. Bait treatments have no residual effect on termites once they are removed from the station. Proper inspection in a timely manner is essential for the effectiveness of baits.
Borates or surface treatments for termite control are usually performed during the construction of a home. The borate material is applied to the surface of the wood. The material is absorbed into the wood creating a protective barrier over that portion of wood that is treated. You might see homes being built that have a green or blue dye on the wooden structure. This dye is added to the clear borate solution so the inspector can tell which parts of the wooden structure have been treated. Borate treatments have risdual qualities. They will remain effective for several years.
