Saw one crawling up the wall. By the time I frantically scrambled to grab some tape, it crawled higher. By the time I realized I better use something other than bare hand to apply the tape hoping to trap it, it fell. Now it's whereabouts are unknown and I have a very uneasy feeling. Wiki says they mostly eat plant material, but some are predatory. I think maybe I need to keep clear plastic cups around to trap pests on the wall to remove them without splatter.
