A little easy way to catch small flies and other small flying pest around your plants.
In a small bowl put a drop or 2 of soap detergent and add water .... Gently mix and place the bowl in a close proximity to your plants.
In no time you will see drowned flies in the water. That's due to surface tension, when the flies come to drink they get wet and cant escape the surface.
It's an easy non toxic way to handle a small problem...
