3. Product Overview
Tempo WP Ultra is a pyrethroid-based insecticide containing 10% Cyfluthrin as its active ingredient. It comes in a 14.8 oz (420 gram) powder form. When mixed with water, it forms a suspension that can be applied with a sprayer. The product leaves a clear, almost invisible residue, though a white powdery film may be visible on darker surfaces.

4. Setup and Preparation
4.1 Mixing Instructions
- Determine Application Rate: Refer to the product label for specific mixing ratios based on the target pest and application area.
- Prepare Sprayer: Ensure your sprayer (e.g., 1-gallon hand pump sprayer) is clean and free of other chemicals.
- Add Water: Fill the sprayer tank halfway with water.
- Add Tempo WP Ultra: Carefully measure the required amount of Tempo WP Ultra powder according to the label. Add the powder to the sprayer tank.
- Mix Thoroughly: Agitate the mixture well to ensure the powder is fully suspended.
- Fill to Volume: Add the remaining water to the sprayer tank and agitate again before application.
Each 420 gram tub typically yields approximately 21-42 gallons of finished spray, depending on the pest being treated and the dilution rate specified on the label.
5. Operating and Application
5.1 Target Pests
Tempo WP Ultra is effective against a wide variety of crawling, flying, and wood-infesting pests. This includes general household pests, pantry and stored product pests, and insect pests of trees, landscape ornamentals, and residential/commercial lawns.
5.2 Application Areas
- Indoor: Apply as a crack and crevice treatment, spot treatment, or perimeter treatment in non-food areas of residential, commercial, and industrial buildings.
- Outdoor: Apply to exterior surfaces of buildings, around foundations, on lawns, landscape ornamentals, and trees.
5.3 Application Procedure
Apply the mixed solution using a sprayer to the target areas. Ensure thorough coverage without runoff. For outdoor perimeter treatments, apply to the foundation, around windows and doors, and other points of entry. For turf and ornamental applications, follow specific instructions on the product label regarding spray volume and coverage. Reapply as necessary, but do not exceed the maximum application rates or intervals specified on the label. The residual effect typically lasts for 30 to 90 days.
6. Maintenance and Storage
6.1 Storage
Store Tempo WP Ultra in its original container, tightly closed, in a cool, dry, well-ventilated area, away from food or feed. Prevent cross-contamination with other pesticides, fertilizers, food, and feed. Store above freezing temperatures.

7. Troubleshooting
7.1 Ineffective Control
- Check Dilution: Ensure the product was mixed at the correct concentration as per label instructions for the target pest.
- Application Coverage: Verify that the application provided thorough coverage of the infested areas.
- Pest Identification: Confirm that the target pest is listed on the product label.
- Environmental Factors: Heavy rain or excessive irrigation shortly after application can reduce effectiveness.
7.2 Visible Residue
Tempo WP Ultra is a wettable powder and may leave a white powdery film, especially on dark surfaces. This is a normal characteristic of the product. If a clear residue is preferred, consider using a liquid concentrate insecticide.
