I hate them too! If you don't have small animals, sticky traps stop them. They make poisons in spray form to stop spiders, thay should stop them too. Go to your local farm supply store, they are a wealth of information for DIYers. I bet a spray of peppermint and Neem oil will stop them, mix it strong, and spray your steps coming in. Boric acid works well on ants, might hurt scorpions too. Diatomaceous Earth is hard on any bugs with an exoskeleton, acts like tiny sharp pieces of glass, and slices them open, then dries them out internally

Good Luck, and good hunting !
