Venomous Spiders

What are venomous spiders?

Spiders are arthropods and are a predatory species; they have eight legs, two body segments, no antennae, and specialized mouthparts.  These specialized mouthparts or fangs are hollow and contain or are connected to venomous glands.  Spiders use their venom to paralyze their prey or to defend themselves.
Spiders are beneficial to the environment because they feed on and keep down populations of nuisance insects.  Most spider species are harmless to people and even though they bite their venom is not strong enough to harm a human.  However, there are a few species living in the United States that are considered to be venomous and whose venom is strong enough to pose a threat to people

What do venomous spiders look like?

Two species of venomous spiders that can be found in the Southeast United States include the:

Brown recluse- Brown recluse spiders are known for their violin-like pattern located on the top of their body.  They have three pairs of eyes that are organized into a semi-circle pattern.  Adults can grow to be ¼ to ½ of an inch in length.  The brown recluse spiders abdomen is covered in gray hairs and their body is yellowish-gray to dark brown in color.

Black widow- Black widows are shiny black in color and they have a red “hourglass-like” shape on their back, although this shape can be less defined on some spiders; their abdomen can also have light red or white spots on it. Adult black widow spiders can grow to be 1 ½ - 1 3/8th of an inch in length.

Are venomous spiders aggressive?

Despite what many people think, no, venomous spiders are not particularly aggressive.  They are shy and reclusive and prefer to hide dark undisturbed areas; they don’t want to see you, just as much as you don’t want to see them.  Venomous spiders usually only bite a person if they are being directly handled, threatened, or are being squished like when they are hiding in an article of clothing or in a shoe.

How dangerous are venomous spiders?

As long as medical attention is sought it is very rare that a bite from a black widow or brown recluse spider leads to severe complications or death.  The bite from a black widow spider can affect a person’s nervous system, and symptoms can include tremors, fevers, and difficulty breathing. The venom from a brown recluse spider can cause severe tissue ulceration around the bite site that can take months to heal.
