Earwigs, like centipedes, millipedes, etc, come from outdoor areas that contain organic matter. Usually, this includes areas under shrubs, decks, etc, and areas where water or moisture collects.
They could be breeding and harboring under the porch if there is a space under it.
The best thing to do is to spray the exterior of the home, under the porch, and anywhere earwigs can be living with a residual product such as Bifen.
You may need to spray every few weeks unti the problem goes away. If it doesn't get any better after 2 or 3 treatments, let me know, and we can go into more detail. Outdoor spraying is the standard treatment for earwigs.
Indoors, use ePest IPM Bug traps placed under furniture along walls etc. to capture them.
