Frequently Asked Questions

PestShield emits ultrasonic sound waves at frequencies that are uncomfortable for pests but completely inaudible to humans and most pets. These high-frequency sound waves create an inhospitable environment for rodents, insects, and other pests, driving them away from your home naturally without chemicals or traps.

The device begins working immediately when plugged in. Most customers notice a significant reduction in pest activity within 2-3 weeks as the pests are driven out of your home.

PestShield is effective against a wide range of common household pests:

• Rodents: Mice, rats, squirrels
• Insects: Cockroaches, ants, spiders, silverfish, earwigs, crickets, bed bugs
• Stinging insects: Bees, wasps, hornets

The device is most effective against rodents and crawling insects. Flying insects may be less affected.

Each PestShield unit covers approximately 300 square feet (one average-sized room). We recommend:

• Apartment/Small home: 2-3 units
• Medium home (1,500-2,000 sq ft): 4-6 units
• Large home (2,500+ sq ft): 8+ units

Important: Ultrasonic waves cannot pass through walls, so you need at least one unit per room for full coverage. For best results, place units in areas where you've seen pest activity.

Most customers begin seeing results within 2-3 weeks. Here's what to expect:

• Week 1: Pests may become more active as they're disturbed by the ultrasonic waves
• Week 2-3: Noticeable reduction in pest sightings
• Week 4+: Most pests are driven out; continued protection as long as device is plugged in

For severe infestations, results may take up to 4-6 weeks. Keep the device running continuously for best results.

No! PestShield is completely silent to humans. The ultrasonic frequencies it emits (22-65 kHz) are well above the range of human hearing (20 Hz - 20 kHz). You can place it in your bedroom and sleep peacefully knowing it's protecting your home 24/7.

PestShield is safe for most household pets:

• Dogs & Cats: ✓ Completely safe. They cannot hear the frequencies emitted.
• Fish & Reptiles: ✓ Safe. Unaffected by ultrasonic waves.
• Birds: ✓ Generally safe, though some birds may be sensitive.

Note: If you have pet rodents (hamsters, gerbils, guinea pigs, rabbits), do not use PestShield in the same room as their enclosure, as they will be affected by the ultrasonic waves.
