Instructions:

Mix Ingredients: In the shallow bowl, combine the vinegar and shampoo. Stir until the shampoo is thoroughly mixed with the vinegar.
Add Olive Oil: Slowly pour the olive oil over the mixture. The oil should float on top, creating a thin layer over the liquid.
Set Up Trap: Place the bowl in areas where you notice flies or mosquitoes are prevalent. This could be near doors, windows, or any damp areas.
How It Works:
Attraction: The vinegar acts as a bait due to its strong and fruity scent, which is very attractive to flies and mosquitoes. Apple cider vinegar is especially effective because it naturally ferments, mimicking the scents of decay and fermentation that these insects find irresistible.
Entrapment: The shampoo in the mixture reduces the surface tension of the vinegar, making it easier for the insects to sink if they attempt to land on the liquid’s surface.
