Yellow or amber-colored PVC strip curtains offer a scientifically-proven method to reduce flying insect entry into your facility.
Why Yellow Attracts Fewer Insects
Flying insects are naturally attracted to shorter wavelengths of light (UV). Yellow light has longer wavelengths that are less attractive to insects compared to clear PVC or white surfaces. This passive deterrent significantly reduces insect intrusion.
Scientific Evidence
Studies show yellow strips reduce flying insect entry by up to 60% compared to clear PVC. The effectiveness varies by insect type and environmental conditions. Most effective for restaurants, food processing, and agricultural facilities.
Application Benefits
Yellow PVC provides a dual benefit: insect control plus light filtering. It reduces glare while maintaining visibility. Installation is identical to standard PVC curtains - no additional modifications needed.
Combination Strategy
Yellow PVC works best combined with air curtains and insect killers for comprehensive pest management. This multi-layered approach provides maximum protection for food handling areas.
Cost Effectiveness
Yellow PVC costs slightly more than clear options but provides significant savings by reducing pest-related losses. ROI is typically achieved within months in food service environments.
Conclusion
Yellow PVC strip curtains are a proven, cost-effective insect control method. Chronovex offers premium quality yellow PVC curtains for all applications.
Most flying insects — houseflies, fruit flies, mosquitoes, midges — navigate using ultraviolet vision. Standard clear PVC transmits UV light freely, so insects perceive the doorway as fully open. Anti-insect yellow PVC is dyed in the 540–580 nm wavelength range, which absorbs UV before it transmits through the strip. To insects, the doorway looks closed; to humans, the strip remains visibly transparent enough for safe forklift and pedestrian movement.
Independent field studies in Indian food-processing units show 70–85% reduction in flying-insect crossings within the first 48 hours of switching from clear to yellow strips, with no reduction in human visibility or worker complaints.

Does the yellow tint fade over time? Indoor industrial installations retain 90%+ of the tint at 24 months. Outdoor or direct-sun installations may show visible fade by month 18 and should be replaced at that point for compliance.
Can I combine yellow PVC with an insect killer machine? Yes — in fact this is the recommended HACCP best practice. The curtain reduces ingress; the insect killer captures whatever crosses. See the insect killer comparison.
