FMC Biflex TC: The Ultimate Termite Protection (Bifenthrin 2.5% EC)
Secure your property with the "Double Action" power of Biflex TC.
Biflex TC is a premium termiticide concentrate from FMC Corporation designed to protect civil infrastructure and residential homes. Unlike older chemicals that are harmful to the environment, Biflex uses Bifenthrin, a synthetic pyrethroid that creates a powerful, long-lasting barrier against subterranean termites.
Best For: Pre-construction soil treatment, post-construction home protection, and wood preservation.
Why Choose This Product? Key Benefits
-
⏱️
Instant Knockdown: Paralyzes and eliminates termites immediately upon contact with the treated soil.
-
🛡️
Double Action Barrier: Acts as a repellent shield. It creates a "No-Go" zone that termites detect and avoid, preventing them from even touching your foundation.
-
⏳
Decade-Long Protection: Chemically stable in soil. When applied effectively under foundations, it can provide protection for 10+ years.
-
🌧️
Water Resistant: Binds tightly to soil particles. It does not wash away with rain or leach into groundwater, keeping the barrier intact.
-
🌿
Safer Formulation: Low volatility and reduced odor compared to older organochlorines. Safe for occupants once the application settles.

How It Works: Mode of Action
Biflex TC utilizes a dual-attack mechanism to keep your home safe. It targets the nervous system of the pest.
- Neuro-Paralysis: When a termite touches the chemical, Bifenthrin disrupts the sodium channels in their nerves, causing paralysis and death.
- The Repellent Zone: Unlike some poisons that termites eat unknowingly, Biflex acts as a warning shield. Termites sense the chemical barrier and retreat immediately.
- Colony Exclusion: By repelling workers, it denies the entire colony access to the timber in your home, effectively starving the infestation out.
Note: Because it is a repellent, the chemical barrier must be continuous. Even small gaps can allow termites to enter, so thorough application is key.
Target Applications & Pests
| Target Area / Crop | Target Pest(s) |
|---|---|
| Pre-Construction Soil | Subterranean Termites |
| Post-Construction Building | Termites (Coptotermes, Heterotermes) |
| Timber / Woodwork | Wood Borers & Powder Post Beetles |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" (or per sq. meter for construction) for accurate results.
Standard Mixing Ratio & Application Rates
| Application | Dose (ml / Acre) | Ratio (Chem:Water) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Standard Termite Control | Refer to Manual* | 1 : 49 | 20 ml | N/A |
| High Pressure Areas | Refer to Manual* | 1 : 39 | 25 ml | N/A |
| Wood Treatment | Spray to runoff | Mix in Kerosene | 20 ml | N/A |
*PHI = Pre-Harvest Interval is N/A for structural use. *For soil treatment: Apply 5 Liters of mixed emulsion per square meter of surface area.
How to Apply: Best Practices (IS 6313)
- Timing: For best results, apply during pre-construction (foundation trenches, plinth filling). For existing homes, drill holes at wall-floor junctions.
- Mixing: Ensure the emulsion is white and uniform. Do not mix with other chemicals unless specified.
- Coverage: The goal is saturation. Biflex stays where you put it, so you must ensure no gaps are left in the soil barrier. Gaps = Termite Entry.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid skin contact to prevent tingling sensation (paresthesia).
Frequently Asked Questions
1. How long does Biflex TC protection last?
When applied correctly under a concrete foundation, Biflex TC can provide protection for up to 10 years due to its stability in anaerobic soil conditions.
2. Does it have a strong smell?
Biflex TC has a mild solvent (petroleum-like) odor during application, but it is significantly lower than older chemicals like Chlorpyrifos and dissipates quickly.
3. Is it safe for pets and humans?
Once the application has dried and is covered by soil or flooring, the risk to occupants is negligible. However, during application, keep pets away. It is toxic to fish.
4. Can I use kerosene instead of water?
Yes, but only for treating wood/timber to improve penetration. For soil treatment, always dilute with water.
5. What is the difference between Biflex and Bayer Premise?
Biflex (Bifenthrin) is a Repellent (termites stay away). Premise (Imidacloprid) is Non-Repellent (termites enter, get infected, and die). Biflex is often preferred for pre-construction barriers.
