                                                           It's impossible to ban spiders completely, but you can discourage them by reducing prey-- insects, millipedes, etc. Check cereals/flour and woolens for beetles/moths. Examine potted plants for insects. Check bathroom and kitchen at night for silverfish/cockroaches. Clean these out and the spiders will leave, too.
