Brown Widow Spiders in Florida
Brown widow spiders, often referred to as cobweb spiders, are known for their irregular webs and distinct hourglass marking. Though less harmful than their black widow counterparts, they are still venomous and can pose a risk if disturbed. Originally introduced to the U.S. via Florida, these spiders thrive in warm weather. Female brown widows inject a neurotoxin when they bite, though the venom is not typically as dangerous as that of black widows.
Brown Widow Spider Habitat
Brown widow spiders thrive in quiet, sheltered spaces both indoors and outdoors, where they can build their irregular webs. Common web locations include buckets, nursery pots, mailboxes, and entryway corners. They are also frequently found in storage closets, garages, and under eaves, as well as on outdoor furniture and along wrought iron railings. Unlike black widows, brown widows often choose more exposed areas, which increases the likelihood of human encounters.
Brown Widow Spider Behaviors, Threats, or Dangers
Although the venom of a brown widow spider is twice as potent as that of a black widow, these timid spiders typically inject less toxin, resulting in milder symptoms. Their bites rarely pose a significant medical threat. Male and immature brown widow spiders do not bite, and the species actively avoids human interaction. That said, individuals sensitive to spider bites should seek medical attention if bitten, especially if swelling or pain occurs.
