Common house spiders include:
- Cobweb spider, which requires high humidity and plentiful
prey; it typically occurs in damp basements, cellars, crawl spaces, and outbuildings.
- Cellar spider, found in the dark corner of damp places
such as cellars, basements, crawlspaces, and outbuildings. Cellar spiders
can quickly establish large populations in a structure. They are often confused
with the “daddy long legs.”
- Funnel web spider, which constructs large,
flat, horizontal webs containing a funnel at one end where the spider hides
in wait of a victim.
- Wolf spider, which is a hunting spider that’s a
fast runner and will chase prey. They usually occur outdoors, but may
wander indoors in search of prey. They tend to stay at or near floor level
and construct web retreats in sheltered sites.
- Jumping spiders, which make quick, sudden jumps to capture
prey or avoid a threat. They also can walk backward. Active during
the day with a preference for sunshine, their hunting activities often center
about windows and entry doors where their prey is most common.

- Yellow sac spiders, invade structures in the fall
when the weather turns cool and their outdoor food supply disappears. Indoors,
they can be observed on walls and ceilings, but drop to the floor to seek
cover when disturbed. Their small, white, paper-like sacs are often found
in easily overlooked locations, along ceilings and corners, or behind pictures
and shelves. Experts believe sac spiders cause more bites than any
other type of spider.

Daddy-long-legs, also known as harvestmen, are commonly mistaken
for a spider due to their general appearance and eight legs. Daddy-long-legs
are usually not encountered in living areas of a building, but are more often
found in crawl spaces, basements, and outbuildings.
