The best way to get rid of earwigs indoors is to avoid them coming in. Moist areas in your house are the places that attract them. So keep the house clean and avoid the floors becoming wet. Make sure that the windows screens are properly fixed so that the earwigs do not come in. The cracks and the holes in the doors and the door frames have to be fixed so that they do not come in through them. These are the obvious entrances for the earwigs. Use boric acid powder near the cracks, holes and any other entrance that is likely to be used by the earwigs. It is good insecticide and it might kill it if the earwigs come in through the boric acid powder. Another way to get rid of the earwigs colonies is to vacuum it up if you find any large population. Make sure that you are also cleaning the eggs from that area. Dispose the vacuum bag immediately.
