                            Although they are generalist predators, apt to eat anything they can catch, spiders regularly capture nuisance pests and even disease-carrying insects – for example, mosquitoes. ... So killing a spider doesn't just cost the arachnid its life, it may take an important predator out of your home. It's natural to fear spiders.

                                   Eucalyptus, tea-tree or even peppermint oils might keep the spiders out. While some might enjoy the smell, the spiders do not. Spray around windows and doors. A similar option is vinegar.

                            The story goes that conkers contain a noxious chemical that repels spiders but no-one's ever been able to scientifically prove it. There's hearsay that if a spider gets close to a conker it will curl its legs up and die within one day. Others say spiders will happily crawl over conkers with no ill effects at all.

                            Vinegar: Mix equal parts white vinegar and water in a spray bottle and spray it directly onto any spiders you see. Vinegar contains acetic acid which burns the spider upon contact..

                            A corner provides attachment points with some air between them. Imagine a spider building a web in the middle of a blank wall. The web would end up lying flat on the wall, which is not very useful for catching flying insects..

                            Leaving lights on when it's dark: Just like a bear that is attracted to a flowing river filled with jumping fish, spiders are attracted to bright lights, surrounded by flying insects. Any place that is near an insect-attracting light is prime real estate for spiders.
