Hi Darlis. I'm Cindy. Mix equal parts of white vinegar and water in a spray bottle. Use it to directly spray any spiders you see. Vinegar contains acetic acid which kills spiders on contact.
Hi Darlis - We use this spray in conjunction with our swiffer and in addition to be a great duster spray, it helps to keep spiders and other buggies at a minimum. Hope this helps! Hugs, Holly

peppermint oil in a spray is supposed to work well for spiders.
