1/4 cup of shampoo in your preferred scent
A shallow or oval-shaped plate
First thing to do: Bring together Items required: In the little basin, combine the vinegar and shampoo. Thoroughly mix the vinegar and shampoo by swirling them together.
You need to add olive oil. A bit at a time, drizzle the olive oil into the dish. If everything is working as it should, a small layer of oil should rise to the surface of the liquid.
Set up the Trap: Set the basin someplace that gets a lot of fly or mosquito traffic. Potential candidates include any damp areas, such as those next to doors or windows.
What Happens Next:
Flying insects and mosquitoes are lured in by the strong and enticing scent of vinegar. Because of its natural fermenting characteristics, apple cider vinegar is very efficient in killing these insects.
As a result of the shampoo in the mixture lowering the surface tension of the vinegar, insects that attempt to land on its surface will find it easier to sink, creating an entrapment effect.
On top of the mixture, the olive oil forms a slick barrier. When you insert flies or mosquitoes into the trap, especially via the holes in the plastic wrap, the oil will smother them, making it difficult for them to fly away.
Warning: This trap is not poisonous and may be used safely around the home, even near dogs and children. However, store it in an inaccessible area if you’re concerned about spills.
