Setup

1. Unpack: Carefully remove the LEMENG Ultrasonic Pest Repeller units from their packaging.
2. Placement:
   • Plug the device into a standard electrical outlet.
   • For optimal performance, place the device at a height of 30-150 cm (approximately 12-59 inches) from the ground.
   • Ensure there are no large obstructions such as curtains, carpets, or furniture directly in front of the device, as these can absorb ultrasonic waves and reduce effectiveness.

Operating Instructions

The LEMENG Ultrasonic Pest Repeller operates continuously once plugged in. It works by emitting irregular ultrasonic frequencies that disrupt the pests' environment, making it undesirable for them to stay.

Expected Results Timeline:

• 3-5 Days: Pests may become more active initially as they are disturbed by the ultrasonic waves. This is a normal part of the process.
• 2 Weeks: A noticeable decrease in pest activity should be observed.
• 3-4 Weeks: Most pests should have disappeared from the treated area. For severe infestations, it may take up to 4-5 weeks to see significant results.

For continuous pest control and to prevent pests from returning, it is recommended to keep the device plugged in and operating continuously.

• Obstruction Check: Regularly check that no objects are blocking the front of the device, ensuring the ultrasonic waves can propagate freely.
• Continuous Operation: For best results, keep the device plugged in and operating continuously.
