Brian and Susan Trost bought the $450,000 home overlooking two golf holes at Whitmoor Country Club in Weldon Spring in October 2007 and soon afterward started seeing brown recluse spiders everywhere, The St. Louis Post-Dispatch reported. Once when showering, Susan Trost dodged a spider as it fell from the ceiling and washed down the drain.
She told St. Louis television station KMOV-TV in 2012 the spiders "started bleeding out of the walls," and at least two pest control companies were unable to eradicate the infestation.
The couple filed a claim in 2008 with their insurance company, State Farm, and a lawsuit against the home's previous owners for not disclosing the brown recluse problem.
At a civil trial in St. Charles County in October 2011, University of Kansas biology professor Jamel Sandidge — considered one of the nation's leading brown recluse researchers — estimated there were between 4,500 and 6,000 spiders in the home. Making matters worse, he said, those calculations were made in the winter when the spiders are least active.
