Are you tired of finding earwigs crawling around your home? Earwigs are a common household pest that can be difficult to get rid of. Luckily, there is a simple and effective solution that you can make yourself using just a few household items.

What You Will Need

  • Plastic cup
  • Scissors or knife
  • Vegetable oil
  • Soy sauce or fish sauce
  • Tape

Steps to Make the DIY Bug Trap Cup

  1. Take a plastic cup and cut a small hole in the bottom of it using scissors or a knife.
  2. Pour a small amount of soy sauce or fish sauce into the cup.
  3. Add enough vegetable oil to cover the surface of the sauce.
  4. Use tape to secure the cup to a surface where you have seen earwigs.

How it Works

Earwigs are attracted to the scent of soy sauce or fish sauce. When they crawl into the cup, they will get trapped in the vegetable oil and drown.

Tips for Success

  • Place several cups around your home where you have seen earwigs.
  • Check and replace the cups regularly, as they may become full or dry out over time.
  • Be sure to dispose of the cups properly to avoid attracting other pests.

Can I use other types of bait besides soy sauce or fish sauce?

Yes, you can use other types of bait such as honey or molasses. Just be sure to mix it with vegetable oil to create a sticky trap.

Will this trap attract other pests?

It is possible that other pests may be attracted to the trap. Be sure to dispose of the cups properly and keep them away from areas where other pests may be present.
