The 90-Day Shield Program: Follow these professional application guidelines to achieve consistent "no webs" results across all treated areas.
Coverage: One 32oz bottle typically covers 800-1,200 linear feet when applied to baseboards, door frames, and entry points as directed.
Standard Application Procedure
Step 1: Preparation
- Shake Container: Shake or agitate the 32oz sprayer bottle vigorously to re-suspend the essential oils before use
- Prime Sprayer: Pump the trigger sprayer head 3-5 times to prime and ensure even flow
- Prepare Area: Remove children and pets from treatment areas
- Ventilation: Ensure adequate ventilation by opening windows or doors
Step 2: Application Technique
Target Areas: Apply a light, even spray (not a heavy soak) along the following areas:
- Baseboards: Entire perimeter of each room, paying special attention to corners
- Door Frames: Interior and exterior door thresholds, frames, and surrounding areas
- Garage Thresholds: Where garage meets living space, including door tracks
- Basement Corners: Floor-to-wall junctions, sill plates, and utility areas
- Window Sills: Interior window frames and sills where spiders may enter
- Storage Areas: Closets, attics, and crawl space entry points
- Known Harborage: Any areas where spider activity has been observed
Spray Pattern: Hold the sprayer 6-12 inches from the surface and apply in a smooth, sweeping motion. Avoid overspray to prevent waste.
Step 3: Contact Kill
For visible spiders, spray directly on the spider for immediate knockdown. The essential oil blend provides contact kill within seconds. After contact kill, treat the surrounding area to prevent re-entry.
Step 4: Drying & Re-Entry
- Drying Time: Allow surfaces to dry fully (typically under 30 minutes, depending on ventilation and humidity)
- Re-Entry: Wait until surfaces are completely dry before allowing children/pets to re-enter treated areas
- Ventilation: Keep areas well-ventilated during and after application
Step 5: Maintenance Schedule
90-Day Reapplication: Reapply every 90 days to maintain the residual barrier. In high-traffic areas or regions with heavy spider activity, reapplication may be needed sooner (every 60-75 days).
Quarterly Maintenance: For consistent results, follow a quarterly maintenance schedule aligned with the 90-Day Shield Program.
Coverage Guidelines
One 32oz Shield90™ sprayer bottle provides targeted coverage when applied correctly:
- Small Home (800-1,000 sq ft): 1 bottle typically sufficient for full interior treatment
- Medium Home (1,000-2,000 sq ft): 1-2 bottles for complete coverage
- Large Home (2,000+ sq ft): 2-3 bottles for comprehensive treatment
- Multi-Unit Applications: Coverage varies by unit size and application density
Note: Coverage depends on spray rate, surface porosity, and frequency of reapplication. Professional applications may vary.
Best Practices for Property Managers
Efficient Application Strategies
- Batch Processing: Treat multiple units in sequence for efficient use of time and product
- Systematic Approach: Start at entry points and work through each unit methodically
- Documentation: Maintain records of application dates and areas treated
- Tenant Communication: Notify tenants in advance of scheduled maintenance
High-Traffic Area Considerations
Areas that require more frequent reapplication:
- Entryways and doorways with frequent foot traffic
- Garage thresholds that are cleaned or exposed to moisture
- Basements with high humidity or water exposure
- Exterior-to-interior transition points
In these areas, monitor effectiveness and reapply every 60-75 days if needed.
Indoor vs. Outdoor Application
Indoor Use
Shield90™ is designed for indoor and garage use. Ideal indoor application areas include:
- Living spaces, bedrooms, and common areas
- Basements and utility rooms
- Garages and attached storage areas
- Crawl spaces and attics (accessible areas)
Garage Use
Garages are prime spider entry points. Focus application on:
- Garage door thresholds and tracks
- Interior-to-garage door frames
- Perimeter baseboards
- Utility entry points
Outdoor Use
While Shield90™ is primarily formulated for indoor use, it can be applied to outdoor entry points such as:
- Exterior door frames and thresholds
- Window frames and sills
- Foundation-to-structure junctions
Note: Outdoor applications may require more frequent reapplication due to weather exposure.
Surface Compatibility
Shield90™ is safe for most common household surfaces:
- Safe Surfaces: Painted walls, baseboards, door frames, wood, concrete, tile, and most non-porous materials
- Test First: On delicate surfaces or antiques, test a small, inconspicuous area first
- Avoid: Direct application to food preparation surfaces, dishes, or cooking areas
- Residue: Formula dries to an invisible, non-oily finish that doesn't leave sticky residue
Troubleshooting Common Issues
Uneven Application
Problem: Patchy coverage or missed areas
Solution: Ensure proper sprayer priming and maintain consistent distance (6-12 inches) from surface. Use a systematic approach to avoid missed spots.
Reduced Effectiveness
Problem: Spiders returning before 90-day period
Solution: Increase frequency of reapplication to 60-75 days in high-traffic or high-humidity areas. Ensure thorough coverage of all entry points.
Sprayer Issues
Problem: Clogged or inconsistent spray pattern
Solution: Clean sprayer nozzle with warm water. Ensure proper shaking before use to suspend oils evenly.
Professional Application Tips
- Temperature: Apply at room temperature (68-77°F) for optimal performance
- Humidity: Higher humidity may extend drying time; ensure adequate ventilation
- Timing: Apply during dry weather conditions for best surface adhesion
- Consistency: Maintain consistent spray rate for even coverage
- Safety: No special protective equipment required; wash hands after use
Multi-Unit Application Schedule
For property managers treating multiple units:
- Assessment: Survey units to identify high-priority areas
- Scheduling: Plan application during tenant turnover or scheduled maintenance windows
- Efficiency: Batch treat similar units (same floor, similar layout) in sequence
- Documentation: Track application dates and follow up at 90-day intervals
- Communication: Maintain records for tenant communication and maintenance logs
