Paxton Imidacloprid 30.5% SC Termiticide: Colony Elimination for Structural Protection
Protect your property with Paxton, the **advanced, non-repellent termiticide** (formerly FMC, now **Envu**). Its unique "Domino Effect" kills termites in the treated soil and spreads back to eliminate the entire colony, providing **long-lasting, comprehensive protection** for pre- and post-construction.
**Paxton is a specialized termiticide** for professionals, far superior to general agricultural chemicals. It is odorless, non-staining, and engineered to **bind to soil** for reliable, long-term termite defense.
Active Ingredient: Imidacloprid 30.5% SC (Suspension Concentrate)
Why Choose Paxton Termiticide? Key Benefits for Professionals
-
⏱️
Colony Elimination ("Domino Effect"): Termites cannot detect the chemical, so they pass through the treated soil. The slow-acting formula allows them to carry the toxin back to the nest, eliminating the queen and colony via social transfer (Trophallaxis/Grooming).
-
🛡️
Non-Repellent & Barrier-Fixing: Unlike older repellent chemicals, Paxton is undetectable. This overcomes "Gap Vulnerability"—if the barrier is not perfect, termites still enter and get a lethal dose, ensuring a robust, continuous shield.
-
⏳
Long-Term Structural Protection: The advanced Suspension Concentrate (SC) formulation is designed for high soil-binding capacity, minimizing leaching and ensuring the chemical remains in place for **5+ years** of residual control.
-
🌧️
Odorless & Non-Staining Formula: As a water-based SC, Paxton is virtually odorless and won't stain expensive floorings or masonry, making it ideal for sensitive post-construction remediation.
-
🌿
High Safety Profile: Imidacloprid is highly selective, targeting the insect nervous system with low volatility and relatively low mammalian toxicity compared to older chemicals like Chlorpyrifos.

How It Works: The Non-Repellent Mode of Action (MoA)
Paxton's efficacy is based on its neurotoxic effect and the resulting **horizontal transfer** within the termite colony—the core of the "Domino Effect."
- Neurotoxic Effect (Agonist Action): Imidacloprid mimics the neurotransmitter Acetylcholine and binds irreversibly to the **Nicotinic Acetylcholine Receptors (nAChR)** in the termite's central nervous system (IRAC Group 4A).
- Continuous Nerve Firing: Since the insecticide cannot be broken down by the usual enzymes, it causes the nerve to **fire uncontrollably**. This leads to hyperexcitation, paralysis, and eventually, a delayed death.
- Colony Transfer (Domino Effect): The delay in mortality is intentional. The intoxicated termite returns to the colony and transfers the lethal dose to unexposed nestmates (soldiers, queen, brood) through **Trophallaxis** (food sharing) and **Allogrooming** (social cleaning). This ensures the chemical bypasses the barrier and achieves true colony suppression.
This non-repellent approach is highly successful because termites **cannot detect or avoid** the Paxton-treated soil.
Target Pests & Crops: Professional Termite Control
| Crop/Application | Target Pest(s) |
|---|---|
| Pre-Construction Termite Treatment (IS 6313 Part 2) | Subterranean Termites (e.g., *Odontotermes* spp., *Coptotermes* spp.) |
| Post-Construction Remediation (IS 6313 Part 3) | Subterranean Termites (for existing buildings/infestations) |
| Structural Perimeter/Soil Treatment | Foraging Termite Workers |
Dosage & Application Guide: Following IS 6313 Standards
The Golden Rule: Always follow the **Standard Dilution Rate of 2.1 mL/L** to achieve the required **0.075% a.i. concentration**. This is essential for long-term efficacy and horizontal transfer.
Application Dosage for Structural Termite Control
| Application Zone (IS 6313 Standard) | Dilution Rate (mL / Litre) | Volume (L / Unit Area) | Dose (ml / Acre) | Target A.I. % |
|---|---|---|---|---|
| Pre-Construction: Foundation/Vertical Surface | 2.1 mL | 7.5 L per $m^2$ | ~8,490* | 0.075% |
| Pre-Construction: Plinth Filling (Sub-Slab) | 2.1 mL | 5.0 L per $m^2$ | ~5,660* | 0.075% |
| Post-Construction: Wall-Floor Junction (Drill/Inject) | 2.1 mL | Volume to Refusal/Saturation | N/A | 0.075% |
*The Dose per Acre is an approximate conversion for large-scale agricultural metrics, provided for reference. **For structural pest control, the exact dosage must be based on the required Litres per square meter ($m^2$) as per IS 6313 standards.**
How to Apply Paxton: Best Practices for PMPs
- Timing for Pre-Construction: Apply the emulsion to the plinth filling *after* compaction but *before* the concrete floor slab is laid. For foundations, treat the trenches/vertical surfaces immediately after digging.
- Mixing & Agitation: Mix **2.1 mL of Paxton concentrate** with **1 Litre of clean water**. As it is an SC formulation (a suspension of fine particles), ensure thorough and continuous agitation to prevent the active ingredient from settling in the tank.
- Complete Soil Saturation: The primary goal is to **saturate the soil** to create a continuous chemical barrier. Use rodding (making deep holes) in compacted areas to ensure the solution penetrates the required depth ($50-75\text{ mm}$ minimum) for effective barrier creation.
- Safety: Always wear **PPE** (gloves, mask, goggles, and overalls) as mandated by the MSDS to prevent inhalation of mist and contact with the concentrate. Wash hands thoroughly after use.
Frequently Asked Questions (FAQs) for Termite Control
1. Is Paxton (Envu) the same as the old FMC Paxton?
Yes. Paxton was acquired by Envu (formerly Bayer Environmental Science) from FMC. Both products contain the exact same, high-quality Imidacloprid 30.5% SC formulation. Envu is the current legitimate manufacturer and brand steward.
2. How does Paxton eliminate the colony when it's slow-acting?
The delayed effect is key. Termites pick up the chemical but don't die right away. They then return to the nest and pass the toxicant to other termites, including the queen and brood, through grooming and food sharing (Trophallaxis), which is the "Domino Effect" that achieves colony-level management.
3. Can I use agricultural Imidacloprid 17.8% SL for termite control?
No. Paxton is a specialized 30.5% SC formulation engineered for **soil binding and long-term residual action** against subterranean termites, as mandated by structural standards (IS 6313). Agricultural formulations are weaker, have different soil mobility, and using them for structural control is a violation of product labels and the Insecticides Act.
4. Why is a non-repellent chemical better than an older repellent like Bifenthrin?
Repellents only create a barrier. If there is a small gap, termites will find it and bypass it. Non-repellents like Paxton allow termites to enter the treated zone unknowingly, ensuring exposure and activating the crucial colony-transfer (Domino Effect), providing a far more reliable long-term solution.
5. What is the shelf life of Paxton when stored correctly?
When stored in a cool, dry, well-ventilated area away from direct sunlight and heat, Paxton has a minimum shelf life of **2 years** from the date of manufacture. Always check the official product label for the precise expiry date.
