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.
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.
Spider webs are the main nuisance associated with house spiders, which can be constructed in upper corners, closets, window frames, furniture, basement and garage areas, crawlspaces, etc. Outside they usually can be found under eaves or around windows where light is present attracting prey.
Vacuums can be used to remove adults, egg sacs and webs. Exterior perimeter treatments by pest management professional are effective in preventing spiders from foraging into structures. Contact us today to learn more.
