Chemical insecticides can be used to kill spiders and to keep them from returning. Spray products should be applied to any area where spiders appear, particularly under furniture and in the corners of rooms. Chemical dust products are also useful, especially for uninhabited areas such as attics or crawlspaces. Powder insecticides are also effective when applied to surfaces, and these products typically last longer than sprays or dusts. Glue traps are another effective measure and are typically placed in out of reach areas where spiders gather, such as under beds or behind radiators.

A spray solution of peppermint oil and vinegar can also prevent spiders from entering the home. Combine 1 ½ cups of water, ½ cup of white vinegar and 20 drops of peppermint oil into a spray bottle and apply the solution to windowsills and doorways. Eucalyptus oil can also be substituted for peppermint oil.

Cutting down on clutter can also help reduce the number of spiders indoors. Stacks of boxes, piles of old magazines and crowded under-sink areas are all likely to attract spiders. Tidying up these spaces can prevent spiders from gathering and building webs.
