The Spider (1958)

When a man doesn't come home one night his daughter and her boyfriend go out searching and encounter a giant spider in a cave near the man's wrecked car. Coming back with the Sheriff, the spider is seemingly killed by DDT spraying, and the body then hauled for storage in the high school gymnasium. However, a loud dose of rock music by a teenage garage band revives the arachnid and sends it rampaging through the town.
