Termite infestations pose a significant threat to structural integrity in homes and commercial buildings, particularly in regions like Nairobi where warm, humid conditions favor subterranean termite activity. At Bestcare Pest Control, we specialize in effective termite management solutions, with termite injection—also known as soil injection or chemical barrier treatment—serving as one of our primary and highly reliable methods. This technique creates a protective zone that interrupts termite pathways and eliminates colonies efficiently.
Subterranean termites, the most common destructive species, live in soil colonies and tunnel upward to access wooden structures for cellulose. They construct mud tubes to maintain moisture and remain undetected while feeding. Termite injection targets this behavior by establishing a continuous chemical barrier in the soil surrounding the foundation, preventing termites from reaching the building.
The process begins with a thorough inspection by our certified technicians. We assess visible signs of infestation, such as mud tubes, damaged wood, or swarmers, and identify entry points around the perimeter. This evaluation determines the extent of treatment required and ensures compliance with safety and environmental standards.
Preparation involves excavating a shallow trench, typically 15–30 centimeters deep and 15 centimeters wide, along the exterior foundation walls and other vulnerable areas, such as around slabs, patios, or utility penetrations. In cases where trenching is impractical—such as on concrete slabs or patios—technicians drill small holes (approximately 1–2 centimeters in diameter) spaced at regular intervals (usually 30–45 centimeters apart) through the concrete or masonry into the underlying soil. This allows precise access beneath hard surfaces.
Next, a specialized liquid termiticide is applied using professional-grade equipment. Modern non-repellent formulations, such as those containing fipronil or similar active ingredients, are preferred for their effectiveness. Unlike repellent chemicals that termites might detect and avoid, non-repellent termiticides remain undetectable. Termites tunnel through the treated soil, contact the chemical on their bodies, or ingest trace amounts. The slow-acting nature of these products enables a “transfer effect”: affected worker termites return to the colony and inadvertently spread the termiticide through grooming and trophallaxis (food sharing), resulting in widespread colony elimination rather than mere individual kills.
Application rates follow strict label guidelines, typically delivering 4–5 liters of diluted solution per linear meter of trench or per drilled hole, ensuring thorough saturation. For rodding techniques, a specialized soil rod with multiple injection ports is inserted into the trench or drilled holes, distributing the termiticide evenly in several directions under pressure. This creates a uniform barrier zone extending from the surface to the footing depth.
After application, the trench is backfilled with the treated soil, and any drilled holes are sealed to prevent re-infestation and maintain aesthetics. The treated zone binds tightly to soil particles, providing long-lasting protection—often up to 5–10 years, depending on soil type, weather, and product specifications.
At Bestcare Pest Control, we prioritize safety throughout the procedure. Technicians wear appropriate protective equipment, and we select low-toxicity, environmentally responsible products approved for residential use. Post-treatment, we provide clients with documentation, warranty information, and recommendations for ongoing monitoring to sustain protection.
Termite injection offers several advantages: it targets the source of infestations, requires minimal interior disruption, and provides proactive defense against future invasions. While alternative methods like baiting systems exist, soil injection remains a cornerstone of effective subterranean termite control due to its reliability in creating an impenetrable barrier.
