Cockroach Mosquito and Fly Killer Beta-Cypermethrin and Tetramethrin EC

Beta-cypermethrin 12% + Tetramethrin 4% + Piperonyl Butoxide 16% EC

Beta-Cypermethrin and Tetramethrin EC,A highly effective public health insecticide combining rapid knockdown, strong residual control, and synergistic performance. Tetramethrin delivers rapid knockdown of flying and crawling insects, while Beta-cypermethrin provides long-lasting residual protection. Meanwhile, PBO enhances overall insecticidal activity and helps overcome resistant pest populations.It is widely used for controlling mosquitoes, flies, cockroaches, fleas, bed bugs, and other public health pests in residential, commercial, and industrial environments, achieving rapid knockdown of mosquitoes and flies within minutes of exposure and over 90% control efficacy under recommended application conditions.

1.Beta-Cypermethrin and Tetramethrin EC Mode of action

Unlike ordinary single-component insecticides, our product forms a three-dimensional pest control system with three core ingredients.

• Tetramethrin 4% acts as a fast-acting knockdown agent, which can quickly paralyze and kill flying and crawling pests on contact, achieving immediate insecticidal effect and eliminating active pest infestation in a short time.
• Beta-cypermethrin 12% provides stable and long-lasting residual activity. After spraying, a protective insecticidal film is formed on the surface of the treated area, which can continuously inhibit pest reproduction and prevent repeated infestation for weeks.
• As a professional synergist, Piperonyl Butoxide 16% plays a key role in breaking pest resistance. It effectively inhibits the metabolic detoxification enzyme system of pests, greatly enhances the absorption and insecticidal activity of the two pyrethroid ingredients, reduces pesticide dosage, and significantly improves the control effect on resistant mosquitoes, cockroaches, ants and other stubborn pests.
  The triple synergistic formula ensures high efficiency, stability and durability of pest control.

2.Product Advantages

1. Rapid Knockdown: Quickly eliminates flying and crawling insects; takes effect immediately upon spraying, making it ideal for urgent pest control needs.
2. Long-Lasting Protection: Forms a protective barrier after application that blocks pest intrusion and provides continuous protection for weeks.
3. Resistance-Breaking Formula: Enhanced with synergists to remain highly effective against stubborn, resistant pests, suitable for scenarios requiring repeated, long-term treatment.
4. Broad-Spectrum Efficacy: Targets a wide range of common harmful insects found in homes, public areas, and gardens.
5. High-Quality Formulation: Stable EC (Emulsifiable Concentrate) formula; emulsifies evenly in water without sediment or nozzle clogging, ensuring easy application.
6. Low-Residue Profile: Compliant formula leaves no stubborn residues on treated surfaces, offering greater peace of mind for use in living environments.

3.Target Pests and Application Scenarios

Target Pests: Mosquitoes, flies, cockroaches, ants, fleas, termites, and various other crawling and flying pests affecting public health.

Application Areas: Homes, hotels and restaurants, office buildings, shopping malls and supermarkets, public health areas, residential courtyards, livestock farms, outdoor gardens, etc.

4.Usage Instructions and Dilution Ratios

• Routine environmental disinfection and pest control: Dilute with water at a ratio of 1:100–1:200 and spray evenly onto walls, floors, crevices, corners, and other areas where pests harbor.
• Stubborn pests/high-density infestations: Dilute with water at a ratio of 1:80–1:100 and apply via targeted spraying on areas where pests congregate.
• Application methods:It is suitable for conventional spraying or residual spraying. In addition, it is compatible with various manual and electric spraying equipment.

5.Warm Notes & Compatibility Rules

1. Acid-base Compatibility Taboo: This product contains pyrethroid ingredients (Beta-cypermethrin, Tetramethrin). DO NOT mix or contact any alkaline substances, including alkaline pesticides, alkaline disinfectants, lime water, Bordeaux mixture and caustic preparations. Alkaline conditions will decompose active ingredients, cause emulsion breaking, precipitation and efficacy failure. This insecticide is only stable in neutral or weakly acidic solutions. Therefore, strong acid mixtures are strictly prohibited to avoid ingredient degradation.
2. Water Quality Requirement: Use only clean fresh water for dilution. Hard water, seawater and turbid water will damage the emulsifying system, causing layering, sediment and nozzle clogging.
3. Mixing Regulation: Do not mix with unknown pesticides arbitrarily. Before tank mixing, always conduct a pre-mix compatibility test. Furthermore, in addition, avoid mixing more than two agrochemicals at one time to minimize the risk of antagonistic reactions. As a result, this helps ensure better product performance and application safety.
4. Temperature &amp:The optimal application temperature ranges from 15℃ to 30℃, ensuring maximum insecticidal activity and stable emulsion performance. Do not apply under direct intense sunlight or at temperatures above 35℃, as high heat will accelerate active ingredient volatilization and decomposition, reducing efficacy and increasing inhalation risk. Avoid application below 10℃, low temperature will weaken pyrethroid activity, slow emulsification and shorten residual duration. Do not spray on windy or rainy days. In case of rainfall within 2 hours after application, re-spraying is required. Meanwhile, keep proper ventilation during indoor treatment.
5. Storage Safety: Store sealed in cool, dry and dark places with storage temperature between 0℃–30℃. Do not expose the product to freezing conditions, high-temperature stacking, or long-term sun exposure to prevent emulsion deterioration.
