Advertisement I have a little brown house spider living in my cotton ball cup in my bathroom. It just molted yesterday, which was feeding day. How long do house spiders fangs take to harden? Is it similar to tarantulas? Also, just thought i'd share a story and ask more questions . While at work my co workers called me to let me know a spider was in the hallway. Turns out it is an american house spider and I also grabbed an eggsack that was hanging nearby. When I put the eggsack in the container I did a poor job and it was hanging but also sitting on the coco fiber. Today I noticed that she had moved it up higher in the fake plant. Does this mean it is fertile? Also, when I dropped a pinhead cricket into the container it totally missed the webbing. Will she hunt the crickets down or do they have to land in the web? Thank you.
