The Southern House Spider is more often found indoors in wall cracks, windowsills and shutters of homes.





On first glance, homeowners may think a male Southern House Spider is a Brown Recluse thanks to similar colors and body shape, however, Southern House Spiders do not have the violin-shaped mark on their heads. Their venom is not toxic like the Recluse, but they may bite if they feel trapped and that bite may cause some pain. The Southern House Spider actually does homeowners a good service by eliminating pest insects like flies, roaches, beetles and wasps. For those not interested, consistent cleaning of corners, baseboards and window frames with a vacuum will help prevent them from moving in.

Males are large and fast-moving wanderers, searching for both prey and females to mate with. They tend to frighten people because of their size and speed, but mostly for their tendency to crawl over body parts to get to where they want to go. They have spindly legs and look different from females. Females have fat, bulbous bodies and thicker legs. Females prefer to stay in their webs, hiding away in the crevice of a wall or floor. They do not produce a sticky web. Instead, the spider silk is teased to form a mess of threads that entangle insects walking across it. Females build the silk into large, flat sheets of webbing. Over time, the web becomes littered with dust, debris and dead carcasses of meals, but it does not bother the spider.

Spider Anatomy (Typical)
Graphic showing basic parts of spider anatomy
1
Legs: Spiders have four pairs of legs and these are attached to the cephalothorax.
2
Pedipalps: Small appendages near the mouth used as taste and smell organs.
3
Cephalothorax: Contains eyes, head, mouthparts, and legs.
4
Abdomen: Contains various organs related to digestion, reproduction, and web-making.
5
Spinnerets: Used in the production of spider silk for fashioning webs or catching prey.
NOTE: Unlike insects, spiders have both an endoskeleton (internal) and exoskeleton (external).


Territorial Reach (A-to-Z)
Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed below as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections below indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.

Territorial Area Map (Visual Reference Guide)
The map below showcases (in red) the states and territories of North America where the Southern House Spider may be found (but is not limited to). This sort of data can be useful in seeing concentrations of a particular species over the continent as well as revealing possible migratory patterns over a species' given lifespan. Some species are naturally confined by environment, weather, mating habits, food resources and the like while others see widespread expansion across most, or all, of North America.
