FMC Biflex TC Termiticide (Bifenthrin 2.5% EC) - Premium Termite Protection
The "Double Action" shield that kills termites and prevents them from returning.
FMC Biflex TC is the gold standard in structural pest management. Unlike older chemicals that eventually fade, Biflex TC creates a robust, water-resistant chemical barrier around your home's foundation. It doesn't just kill termites on contact; it creates a "No-Go" exclusion zone that repels the colony, keeping your property safe for years.
Best For: Pre-construction soil treatment, post-construction anti-termite treatment, and protecting woodwork from borers.
Why Choose This Product? Key Benefits
- ⏱️Long-Lasting Residual Protection: Stays active in the soil for 10+ years (under ideal conditions) due to superior chemical stability.
- ?️Double Action Defense: Acts as both a lethal contact killer and a potent repellent, denying termites access to your structure.
- ⏳Immediate Knockdown: Stops termite damage instantly upon application by paralyzing the pest's nervous system.
- ?️Water & Leaching Resistant: Binds tightly to soil particles (High Koc value), ensuring the barrier doesn't wash away during heavy rains.
- ?Low Volatility & Odor: Safe for indoor use when applied correctly; the mild solvent smell dissipates quickly after drying.

How It Works: Mode of Action
Biflex TC targets the nervous system of the insect.
- The Repellent Shield: When applied to the soil, it creates an irritation zone. Termites detect the chemical before entering and turn away (exclusion).
- Sodium Channel Blockage: If a termite touches the barrier, Bifenthrin wedges the sodium channels in their nerves open.
- Nervous System Failure: This causes uncontrollable tremors and hyperexcitation, leading to paralysis and death of the pest.
Note: Because it repels termites, it is crucial to apply a continuous barrier without gaps.
Target Crops & Pests
| Area / Surface | Target Pest(s) |
|---|---|
| Building Foundations (Soil) | Subterranean Termites |
| Woodwork & Furniture | Wood Borers, Powder Post Beetles |
| Pre & Post Construction | Termite Colonies (Coptotermes, etc.) |
Dosage & Application Guide
The Golden Rule: Always follow the ratio of 1 Liter Biflex to 49 Liters of Water for standard termite control.
Dosage per Application Type
| Application Type | Dose (ml / Litre) | Ratio (Chem : Diluent) | Diluent |
|---|---|---|---|
| Standard Termite Control (Soil) | 20 ml | 1 : 49 | Water |
| High Infestation Areas | 25 ml | 1 : 39 | Water |
| Wood Treatment (Borers) | 20 ml | 1 : 49 | Kerosene / Mineral Oil |
*For wood treatment, using Kerosene aids deep penetration into the timber fibers.
How to Apply: Best Practices
- Timing: Apply during pre-construction (foundation/plinth) or via drilling holes in existing floors (post-construction).
- Mixing: Pour the required quantity of Biflex TC into a small amount of water to make a slurry, then add the remaining water and stir well.
- Coverage: Ensure the soil is thoroughly saturated. For walls/floors, inject until "refusal" (backflow occurs) to ensure no gaps remain.
- Safety: Always wear PPE (gloves, mask, goggles). Bifenthrin can cause a temporary tingling sensation (paresthesia) on the skin; wash immediately if contact occurs.
Frequently Asked Questions
1. How long does the protection last?
When applied correctly according to IS 6313 standards, Biflex TC remains active in the soil for 10 years or more, especially under covered areas like foundations.
2. Does it have a strong smell?
The product is an Emulsifiable Concentrate (EC) and contains solvents, so it has a mild chemical odor during application. However, this dissipates rapidly once the treated area dries.
3. Is it safe for pets and children?
Keep children and pets away during the application and while surfaces are wet. Once the application is dry and the holes are sealed, it is safe for normal occupancy.
4. What is the difference between killing and repelling?
Kill-only products allow termites to enter and die later. Biflex TC is a "Repellent" which stops termites from even attempting to cross the treated soil barrier.
5. Can I use this for wood borer protection?
Yes. For wood borers, mix Biflex TC with kerosene or mineral oil (instead of water) to ensure the chemical penetrates deep into the wood pores.
