There is some evidence to suggest that certain ultrasonic frequencies can repel ants and other pests. Ultrasonic pest repellers emit high-frequency sound waves that are typically inaudible to humans and pets but can be disturbing to insects and rodents. These devices are designed to create an uncomfortable environment for pests, encouraging them to leave the area.
However, the effectiveness of ultrasonic pest repellers can vary, and not all studies agree on their efficacy. If you decide to try this method, it might be worth experimenting to see if it works for your specific situation. Just ensure that the device is placed in a way that covers the area where you are stored.
