It's only natural to flee for warmer climes when cold weather strikes. Birds fly south for the winter, grizzly bears hunker down in dens and old folks buy condos in Florida. If you've ever had to wait outside for a bus on a cold winter day, you may find yourself wondering why you left the house at all.

So it would seem to make sense that spiders are more likely to turn up indoors during the cold months. But in truth, most of the spiders found indoors come from a long line of house spiders that have evolved over the years to adapt a life of a constant, temperate climate and poor sources of food and water. These spiders leave their eggs in furniture and other home fixtures. They're actually more likely to be found in large groups during the late summer months, their prime mating season [source: Crawford].

Keeping this in mind, you'll understand why our next myth is also baloney.
