Paxton (Imidacloprid 30.5% SC): Premium Termite Killer & Structural Protectant
**Paxton is a powerful, non-repellent termiticide from Envu (formerly FMC).** It is the standard-bearer for long-lasting, odorless, and highly effective **pre- and post-construction anti-termite treatment** in compliance with IS 6313.
This advanced **Suspension Concentrate (SC) formulation** ensures deep soil penetration and a unique "Domino Effect" that manages the entire termite colony, not just the foragers. Protect your home and civil structures with the gold standard in termite management.

Why Choose Paxton Termiticide? Key Benefits for Long-Term Protection ?️
- ⏱️ Whole Colony Management ("Domino Effect"): Paxton is non-repellent, meaning termites don't avoid the treated soil. They get a lethal dose, carry it back to the colony, and transfer it to the queen and other nestmates through social contact (**horizontal transfer**), eliminating the infestation at the source.
- ?️ Superior Soil Barrier Integrity: Unlike repellent chemicals, Paxton is a **non-repellent termiticide**. It provides a "forgiving" barrier—even if there are small gaps in the application, termites pass through the chemical, ensuring high exposure and protection.
- ⏳ Long-Lasting Residual Efficacy: The specialized **Suspension Concentrate (SC) formulation** binds effectively to soil particles. This prevents leaching and ensures the chemical barrier remains stable and active for **5+ years**, offering reliable, long-term structural protection.
- ? Odorless and Non-Staining: The water-based SC formulation contains no volatile organic solvents, making it virtually **odorless** and **non-staining**. It is ideal for use in post-construction residential and commercial properties.
- ? Reduced Environmental Impact: Imidacloprid has a favorable safety profile compared to older chemistries (like Chlorpyrifos) due to its **high selectivity** for insect nervous systems over mammalian systems.

How Paxton Works: Neurophysiological Mode of Action (MoA)
Imidacloprid is a neurotoxin that specifically targets the insect's central nervous system, leading to paralysis and death. This **slow-acting nature** is essential for the "Domino Effect" transfer mechanism.
- Non-Repellent Contact: Termites enter the treated soil without detecting the chemical, picking up the toxin on their bodies and ingesting it while tunneling.
- Receptor Agonism: Imidacloprid acts as an **antagonist to the nicotinic acetylcholine receptors (nAChR)** in the termite's brain. It mimics the natural neurotransmitter, Acetylcholine, but the body cannot break it down.
- Continuous Nerve Firing: This binding keeps the nerve impulse transmission permanently **"turned on,"** causing uncontrollable tremors, paralysis, and death due to over-excitation.
**Result:** The intoxicated, but still living, termite transfers the chemical to the entire colony through social feeding (**Trophallaxis**) and grooming, suppressing the entire termite population.
Target Structures & Key Pest Species ?
| Application Scenario | Target Pest(s) |
|---|---|
| Pre-Construction Treatment (IS 6313, Part 2) | Subterranean Termites (e.g., *Odontotermes* and *Coptotermes* species) |
| Post-Construction Remediation (IS 6313, Part 3) | Active Termite Infestations, General Structure Protection |
| Building Types | Residential Homes, Commercial Buildings, Industrial Units, and Warehouses. |
Dosage & Application Guide (Per IS 6313 Standard)
The Golden Rule: Always follow the "Dose per Acre / Dose per Litre" for accurate results to achieve the required **0.075% Active Ingredient** concentration.
Standard Dosage for Anti-Termite Treatment
| Application Type | Dose (ml / Acre) | Water (L / Acre) | **Dose (ml / Litre)** | PHI (Days) |
|---|---|---|---|---|
| Standard Dilution Rate (0.075% a.i.) | *Varies by soil volume (Refer IS 6313) | *Varies by soil volume (Refer IS 6313) | **2.1 mL / Litre** | Not Applicable (Structural Use) |
| Pre-Construction: Plinth Fill Treatment (IS 6313 Part 2) | 10.5 mL / m² (For a 5 Litre/m² application) | 5.0 L / m² | 2.1 mL / Litre | Not Applicable |
| Pre/Post-Construction: Perimeter & Foundation (IS 6313) | 15.75 mL / linear meter (For a 7.5 Litre/linear meter application) | 7.5 L / linear meter | 2.1 mL / Litre | Not Applicable |
*PHI = Pre-Harvest Interval, which is not relevant for structural termite control products.
How to Apply Paxton: Professional Best Practices ?️
- Timing: Apply the treatment when the soil is dry and settled. For pre-construction, treat the foundation trenches and plinth **before** laying the floor slab or filling the soil.
- Mixing: Mix **2.1 mL of Paxton** concentrate with **1 Litre of water** to create the standard 0.075% active ingredient emulsion. Always use a clean water source and agitate well before use.
- Coverage: Ensure **saturation** of the soil. For post-construction, inject the diluted chemical through drilled holes (at 30 cm intervals) at the wall-floor junction until the soil reaches **refusal** (cannot absorb more liquid).
- Safety: Always wear **PPE** (gloves, mask, goggles, coveralls) during mixing and application. Prevent runoff into drains, water bodies, or public areas. Wash hands thoroughly after use.
Frequently Asked Questions (Paxton Imidacloprid)
1. Is Paxton (FMC) the same as Paxton (Envu)?
Yes. FMC's Global Specialty Solutions business, which included the Paxton brand, was acquired by Envu (formerly Bayer Environmental Science). The product is the **exact same Imidacloprid 30.5% SC formulation**, with Envu now holding the regulatory stewardship.
2. How long does the anti-termite treatment last with Paxton?
When applied correctly as per IS 6313 standards (using 2.1 mL/L dilution), the barrier is designed to remain effective in the soil for **5 years or more**, providing long-term residual protection.
3. Can I use agricultural Imidacloprid (e.g., 17.8% SL) instead of Paxton (30.5% SC)?
**No**, you should not. Agricultural formulations have a lower concentration (17.8% SL vs. 30.5% SC) and a different formulation type (SL vs. SC). The SC formulation in Paxton is specifically engineered for soil binding to ensure a durable, long-lasting termite barrier, unlike the SL, which is designed for plant uptake.
4. What is the "Domino Effect" and why is it important?
The "Domino Effect" is the key to colony control. Termites exposed to the non-repellent Paxton return to the nest while still alive. They transfer the toxicant to unexposed nestmates, including the queen, through grooming and feeding (**trophallaxis**), leading to the elimination of the entire colony.
5. Is Paxton safe to use inside a home?
Yes, for post-construction treatment. Its **Suspension Concentrate (SC) formulation** is virtually **odorless** and **non-volatile**, minimizing airborne exposure and making it a safer option for indoor applications compared to older, solvent-based termiticides.
