Overview Of House Spiders In Pennsylvania

House (or “Domestic” or “American”) spiders are the most common type of spider found indoors. Other types of spiders include the wolf spider, brown-recluse spider, hobo spider and cellar spider (“daddy long legs”). It is a nuisance pest, more because of its webs not the spider itself which are thought to be beneficial, because they feed on other insects.

Habits Of Pennsylvania House Spiders

The house spider randomly selects where to establish a web and if it does not yield any prey, it will abandon the site. Webs are usually built where air currents bring in prey. Homes with higher humidity and insect activity are favorable conditions for spiders.
