Common house spider bite symptoms. A common house spider is not an aggressive biter and usually bites humans only to defend itself mainly when grabbed or squeezed. A typical bite of this spider is dry and is just as painful as a bee sting. Some female American house spiders can deliver a spider bite which is sharp and venomous. This kind of bite can cause swelling and itching around the punctured area of the skin and can also trigger antibody allergies in some cases. This is not something to worry about.
