Hi there, I came across your website while trying to find some info on a spider I found in my hallway about 30 min ago. I trapped it and captured the linked photo of it. It was very large compared to any other spiders i’ve seen in our home, which was built in 2006 (two-story colonial with unfinished basement. Backyard faces lightly wooded area.) It is about 3 inches or so from tip of the front leg to tip of the back leg with striped bands on each leg. It’s still in a tuperware container if you need more pictures. My wife and I aren’t typically bothered by anything like this but our only concern is that our 18 month old daughter sleeps on several blankets the floor (long story) less than 5 feet away from where this guy was found. Let me know if you have any questions. Any help is appreciated. Thanks!

Here is the picture in case the link expires:
That pretty lady is a harmless fishing spider, in the genus Dolomedes. I’m almost certain she’s Dolomedes tenebrosus, though there is a possibility that she could be D. scriptus. D. scriptus tends to have white markings around the “W” pattern on the abdomen, so since I can’t make out any white there, I’m going to stick with D. tenebrosus.
Thank you so much for sharing and for your patience!
