The main character's niece wears dresses that would be considered very short by modern standards, but were deemed acceptable in the 1970s, when this movie takes place. In the last 30 minutes of the film, as she is being carried around by adults who are trying to evade the hordes of tarantulas, her white panties can be seen.

One character flirts with his sister-in-law (whose husband died).

A brief female side breast nudity, while she's taking a shower. We see her grabbing a towel (from the shower) sideways. The lightning is not bright, so her left breast is not real clear, from the angle she's in.

Various animals and people are attacked and killed by spiders. Little blood.

Misogynistic behavior and dialogue, typical of the time period.

Some "Oh Gods", "Sweet Jesus", and "G--Darnits". One "Oh S**t"

Many scenes involve spiders attacking people and show resulting bite marks. Some people are shown wrapped in spider silk. A car crash and a plane crash/fireball result from spiders attacking the driver and pilot, respectively.
