Advertisement Giant spider in our house. Instead of leaving him outside, two of us decided to keep him as a pet and currently have him in an interim home until we can get a better set up. Best we've been able to guess, he is a mature male Giant European House Spider. He looks right on coloration, is about the right size (~2 inches), and appeared around the prime sighting time for these spiders: mid September hiding/wandering around the house. Following these forums, I was planning on getting one of the kritter keepers that is about 12" x 6" x 6" to keep him in and some feeder bugs from a nearby pet store. He seems to like the walls we've given made from paper grocery bags better than the paper towel flooring so far, but I'm not sure if a better wall and floor would be cork wood structure and/or another common substrate. Are there better options for food that don't require him to face off against defensive prey (I know that care of snakes more often advocates pre-killed and frozen mice for feeding so they can't injure your pet) or would a wild spider (or spiders in general) by necessity need alive and animate prey? What kind of life expectancy should I prepare for of a mature adult male of this species? Any beginner tips that are easily overlooked when it comes to caring for one's first spider?
