Here are some ideas from Hunker. You basically have to remove anything where they like to create their webs. Wishing you the best.
I would wrap my broom with used dryer sheets or cheesecloth, then spray the broom with spider and ant killer. Then sweep all the beams, corners, door frames, etc. That should kill the spiders, their eggs, and prevent new spiders from moving in. Jewell

Hi Peatrice - 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
