Spiders in my house are funny. They like to zip down from the ceiling to say hi. Plus, they are in an ongoing war against the house flies, and they keep racking up kills. Right now I am rooting for the spiders, but if they keep on making webs in the kitchen, my allegiances will change. So far the ants are a no show. They usually march through during the summer, and scatter around the house, but I set up a defensive line around the foundation of the house with Ortho Home Defense Max (can I have $$$, Ortho, for product placement? No?), so I think we won't see them for a while. I don't like them at all, since they get into food sources and just get everywhere.
