Hi Gretchen, The spiders were basically on most of the traps. But the traps have been out for over a year. I'm new to the collection and I'm just catching up. The strips were all outside the cabinets at the base, at the end of a row. There was some pattern that two of the traps with dermestids were against the same wall, but they were stacks apart from each other. There was also some evidence of "snacking" on dead spiders on other traps. Again, I don't know how recent all this activity is and I will continue to monitor the traps closely for activity. I also set pest strips inside the cabinets where the demestids were found just to see if there is any activity inside.
