Black Widow Spider


Black Widows are shiny and black.  The body can measure up to ¾ of an inch.  Females can be identified by the distinct red hour glass shape on the underside of their abdomen.  Males are smaller with light streaks on their abdomens.


Black Widows are the most venomous spiders in North America.  Bites are very painful and take days to subside.  Black Widows prefer dark secluded areas such as wood piles, basements, crawl spaces, foundations, and beneath patios.  They build their irregular but strong webs low to the ground.  The average life span of a female is 6 months.  Widow Spiders get their name because the female frequently kills the male after mating.


Builds Web In Dark Corners

Spider management starts with a good inspection.  Sanitation goes a long way, moving debris away from the foundation of the home reduces food and harborage for black widows.  Sealing cracks and crevices around the perimeter of the structure is also very effective.  Live Black Widows can be removed by way of vacuuming (caution needs to be taken when opening the vacuum).  A reoccurring thorough perimeter treatment with a residual insecticide gives excellent control.

Fun fact:

The Black Widow Spider has the strongest web out of any other spider.
