Increase in black widow spider numbers

We live in the foothills in Bellvue, Co. (specifically Rist Canyon), an area that was strongly affected by both the High Park Fire (summer 2012) and the recent flooding. Our community has seen a marked increase in the black widow spider population within the last several weeks. Many of us have lived here for 20 years or more, and have never seen anything like this. All the spiders found have been mature and quite large. The males seem larger than has been noted in the past, also. One of us has killed 18 mature females in her home so far this month, after having never seen one in her home in the years prior. Their behavior is also puzzling. They do not appear to be as shy as normal, appearing in groups on the outside surfaces of East facing doors and windows, and building rapidly constructed webs out in the open. They seem to be everywhere, spinning their webs even across doors and gates that are exposed and frequently used. Any idea why this may be occurring at this time? I would like to post your answer on our community board. Thanks!
