McDuffie House Spider Pic


The common house spider is one of the most frequent house guests across the nation. While spiders are considered a nuisance pest, it is most likely due to the presence of their webs versus the role the spiders play themselves.



The most common house spiders you will encounter will have a blended abdomen, typically yellowish brown in color with several angeled dark stripes. Adult house spiders’ appearance will largely vary by sex, the females bost a large spherical abdomen and range from about five to eight millimeters. Their male counterparts have longer oval shaped abdomens and are significantly smaller ranging from three to five millimeters. The number one thing you want to look for when identifying your house spider is the presence of egg sacs. The female house spider can lay up to 250 eggs in silken egg sacs that are spherical and dark brown. These eggs hatch in roughly seven to ten days so it is important to identify them prior to hatching.



Much like the rest of their arachnid family, house spiders like to make their webs in corners of ceilings and outdoor siding. They typically will spin their webs in high places, keeping their egg sacs out of harm's way.


Per their name these spiders prefer to make their webs indoors as it serves to keep their young protected and can provide them with ample food sources in and around the home. While these house spiders serve to protect your home from other creepy crawlies the presence of their webs and egg sacs are quite the nuisance.


House spider prevention starts with properly sealing your home. Using a silicone based caulk, ensure cracks around windows, outdoor siding, and any doors to your home. Upon discovering their web the best method of removal is using a vacuum cleaner to ensure the egg sacs are also completely captured. The use of a broom can prematurely break the egg sacs and release spider offspring throughout your home.
