To keep ants away without using harmful chemicals, you can try some natural methods:

1. **Vinegar Solution**: Wipe down surfaces with a mixture of equal parts water and white vinegar. Ants dislike the smell and will avoid it.

2. **Lemon Juice**: Similar to vinegar, lemon juice can disrupt ant trails and deter them. Spray lemon juice around the area where you are stored.

3. **Cinnamon or Cloves**: Sprinkle ground cinnamon or place whole cloves near where the ants are entering. These spices can act as natural repellents.

4. **Peppermint Oil**: Ants are repelled by the strong scent of peppermint. Mix a few drops of peppermint essential oil with water and spray it around your storage area.

5. **Seal and Store Properly**: Ensure that you are stored in an airtight container or tightly wrapped to prevent ants from getting to you.

Using these natural methods can help keep ants away without turning you into something harmful. 

 are ants repelled by any particular frequency range? 

 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.
