Does Bifenthrin Kill Roaches?
1. How Does Bifenthrin Kill Roaches?
Contact Kill – Roaches die after coming into direct contact with the treated surface.
Residual Effect – Remains effective on treated surfaces for weeks to months, killing roaches over time.
Repellency – Creates a protective barrier, preventing roaches from returning.
Ingestion Poisoning – Roaches groom themselves and ingest bifenthrin after walking over treated areas.
2. How to Apply Bifenthrin for Roach Control
A. Liquid Spray Application (Best for Long-Term Control)
Mix 0.5 – 1.0 fl oz of bifenthrin per gallon of water.
Use a hand sprayer or backpack sprayer.
Apply in cracks, crevices, baseboards, under sinks, and around entry points.
Reapply every 2–4 weeks for continuous protection.
B. Granular Bifenthrin (For Outdoor Roach Prevention)
Apply granules around the foundation of the house, in mulch beds, and near roach hiding areas.
Use at 2–3 lbs per 1,000 sq. ft. and water lightly to activate.
Best for outdoor perimeter control and preventing roaches from entering homes.
C. Dust Form (For Hard-to-Reach Areas)
Apply bifenthrin dust inside wall voids, electrical outlets, and under appliances.
Use a dust applicator for even distribution.
Provides long-term residual control in dry areas.
3. How Long Does Bifenthrin Last Against Roaches?
| Application Type | Effectiveness Duration |
|---|---|
| Liquid Spray (Indoors & Outdoors) | 2–4 weeks |
| Granular Treatment (Outdoor Use) | 1–3 months |
| Dust Application (Wall Voids & Crevices) | 3–6 months |
For severe infestations, reapply every 2–4 weeks and combine with roach baits for better results.
4. Does Bifenthrin Kill Roach Eggs?
- Bifenthrin does NOT kill roach eggs directly.
- However, once eggs hatch, young roaches will crawl over treated areas and die.
- For faster results, use roach growth regulators (IGRs) alongside bifenthrin to prevent eggs from hatching.
5. Is Bifenthrin Safe for Indoor Use?
Safe for use in homes when applied correctly.
Keep children and pets away until the spray is dry.
Avoid spraying directly on food, utensils, or pet areas.
Final Answer: Does Bifenthrin Kill Roaches?
Yes, bifenthrin effectively kills cockroaches through contact, ingestion, and residual exposure.
It provides long-term control when applied as a spray, dust, or granules.
Best results are achieved when combined with baits or IGRs to stop roach reproduction.
Bifenthrin is a powerful insecticide for eliminating both indoor and outdoor roach infestations, making it a top choice for pest control professionals and homeowners.
