An old trick to keep flies and cockroaches away from home

As a student, you must:

You'll need: - Balsamic or apple cider vinegar - Dishwashing liquid - A bowl made of glass - Plastic wrap - A toothpick.

Add two to three centimeters of balsamic or apple cider vinegar to the basin. Shake with a few drops of dish soap to dissolve. Nighttime placement of the bowl in the contaminated region will result in a large number of insect corpses the following day. They tend to be more enticed by the night's darkness and cooler temperatures.
