Hobo Spider, a.k.a. Aggressive House Spider
It is that time of year, spiders are busy building webs, off the web and into those shrubs and flowers you will soon be cutting back, or crawling about your house walls, floors or yikes! under your sheets (how do they get inside and upstairs and under your sheets?). Watch it as you brush up against those flowers and turn down the bedding once in awhile at night (doesn’t that just make your ankle twitch?) and search for the buggers.
