Fire Inhibition for Vegetation & Defensible Space
EPA Safer Choice recognized, food-based chemistry that protects vegetation, roadways, and landscapes — providing long-lasting, clear, and non-toxic fire defense.
CitroTech 31 (MFB-31) is a plant-safe, EPA Safer Choice recognized fire inhibitor for vegetation and defensible space. It dries clear and forms a long-lasting barrier that helps reduce ignition at the surface. Engineered for residential, commercial, and agency use.
Helps lower surface ignition potential on vegetation.
Leaves plants looking natural with no visible residue.
Non-toxic, biodegradable, and EPA Safer Choice recognized.
Creates a durable protective layer that remains effective until rinsed or rained off.

How It Works
CitroTech-31 forms a thin, transparent barrier on vegetation that disrupts the chemical chain reaction required for combustion. It inhibits ignition at the surface while leaving plants healthy and untouched. This is what sets CitroTech apart — lasting protection after a single application, without the limitations of wet foams or gels.
Professional application to vegetation and structures.
Forms an invisible, transparent coating.
Creates a barrier that interrupts ignition.
Trust & Compliance
Our products undergo rigorous third-party testing to ensure the highest standards of safety and performance.
Recognized for environmental and human safety standards.
Low chemical emissions for safe use around people and animals.
Non-toxic certification (LC₅₀ > 750 mg/L).
Independent validation of ignition resistance.
Common Questions
Yes. CitroTech-31 is EPA Safer Choice recognized and formulated to be non-toxic to people, pets, and surrounding vegetation.
CitroTech-31 forms a barrier that persists for years on treated surfaces until rinsed or rained off. Reapplication is rare; we recommend an inspection every five years.
Yes — the formulation is plant-safe and has been tested across native chaparral and conifer species in California's wildland–urban interface.
