In brief: Easy

Bed bugs are numerous.
Their bites are numerous & itchy. Spider bites are rare. When they occur they are single, painful, & ulcerate. Bed bugs make you itch. Spider bites make you sick.

in areas that are exposed while sleeping-arms, shoulders,neck & legs. ***Spider bites can have variable appearances. It might cause a pink or red bump with no symptoms. Or I could itch or be painful. Venomous spiders may cause significant pain radiating far from the site, cramping, sweating, necrosis of tissue or worse if there is an allergic reaction.
