How to deal with household spiders


Contrary to popular belief, spiders do not move indoors looking for winter shelter. Indoor spiders may appear to increase in number due to males wandering in search of a mate.
With the exception of the black widow, there is no reason to be concerned about spiders in Colorado. The occasionally found brown recluse is sometimes brought into the state, but natural populations are not found in Colorado. The remaining spiders are not a threat to human health.
The most commonly found spiders in homes are tegenaria domestica (domestic house spider), dysdera crocata (woodlouse hunter), steatoda triangulosa (a house spider) and cheiricanthium muldei (yellow sac spider). All of these may dwell within the home, spinning webs in out-of-the-way areas and capturing small, soft-bodied insects for prey.
Prevention of spiders within the home involves disturbing favored locations. Regularly vacuum corners, closets and underneath furniture to whisk away small spiders and disrupt webs of larger ones. Gluing board traps located near sources of free moisture, such as behind the toilet, can capture spiders for removal.
