In a predicament that would surely elicit sympathy from Little Miss Muffet, 50 federal government employees were frightened away from their Ottawa office building not once, but twice, after someone spotted a potentially dangerous spider.
In June, managers at 2300 St. Laurent Blvd., a Shared Services Canada building, sent employees home for two days after someone spotted an unusual spider in the office. The building's owner paid to have the offices fumigated before employees returned.
Then, on Oct. 18, there was another spider sighting, but this time it was caught. Over fears it might be a venomous brown recluse, one of only a handful of spiders in North America whose bite can harm humans, the arachnid was sent to an entomologist to be identified.
