I don’t usually recommend [using spider repellents] unless it’s serious…but if you have an infestation, this option might be the best solution for you.
There are [spider repellent products] that focus extensively on safety. Stay Away® Spiders from EarthKind®, for example, contains nothing but all-natural oils. Simply open it, and place it next to a spot where spiders appear. Roughly 30 days later, replace the bag with a new one.
