How can I make a mouse repeller myself? - briefly

Mix water, peppermint oil, and white vinegar in equal parts, spray the solution around entry points and along walls, and reapply weekly to keep rodents away.

How can I make a mouse repeller myself? - in detail

A practical mouse deterrent can be assembled from readily available components. The design relies on ultrasonic sound, vibration, or scent to discourage rodents without harming them.

Materials

• Small ultrasonic transducer (12–20 kHz range) or a piezoelectric buzzer
• 5 V DC power source (USB power bank or 9 V battery with regulator)
• Miniature microcontroller (Arduino Nano, ESP8266) or a simple 555 timer circuit
• On/off switch
• Enclosure (plastic project box)
• Wires, soldering iron, heat‑shrink tubing
• Optional: motion sensor (PIR) for activation only when activity is detected

Construction steps

1. Circuit assembly

   • Connect the microcontroller’s PWM output to the ultrasonic transducer through a current‑limiting resistor (≈100 Ω).
   • Program the controller to emit bursts of 20 kHz pulses for 30 seconds every minute.
   • If using a 555 timer, configure it in astable mode with a 20 kHz frequency and a duty cycle of 50 %.

2. Power integration

   • Attach the power source to the circuit via the switch.
   • Include a voltage regulator if the source exceeds 5 V to protect the components.

3. Housing

   • Mount the transducer on the interior wall of the enclosure, facing outward.
   • Secure all wiring, insulate exposed connections, and seal the box to prevent moisture.

4. Testing

   • Power the device and verify ultrasonic emission with a smartphone app or a frequency meter.
   • Adjust pulse duration or interval if the sound is too weak or overly continuous.

5. Installation

   • Place the completed unit near known rodent pathways—under cabinets, behind appliances, or in crawl spaces.
   • Ensure the device remains at least 12 inches from human ears to avoid discomfort.

Safety considerations

• Avoid direct exposure to ultrasonic output for prolonged periods; maintain a minimum distance of 6 inches from the transducer.
• Use insulated connectors to prevent short circuits.
• Do not place the unit near pets that can hear ultrasonic frequencies.

Alternative methods

• A simple scent repellent can be made by mixing peppermint oil (10 ml) with water (250 ml) and spraying the solution around entry points.
• A vibration deterrent uses a small eccentric rotating mass motor attached to a battery pack; the motor creates continuous low‑frequency tremors that rodents avoid.

By following these steps, a functional, low‑cost mouse deterrent can be built, deployed, and maintained with minimal technical expertise.
