To keep spiders out of the house, keep the house clean and free of dust, since spiders are drawn to it. Close all gaps and holes, being sure to check window and door frames and window screens. Natural deterrents for spiders include white vinegar, citrus and mint.
Keep the spiders out by spraying entrance areas with white vinegar. It is harmless to pets and humans, so it is safe to use anywhere. If the smell is too strong, dilute it with water. Spray it around all doors, windows and any areas of the home where spiders are frequently seen. Spiders also dislike citrus, so setting out citrus fruits in a bowl on the counter is an easy way to keep them out of that space.
