Venomous Spiders to Watch Out for in Georgia

Georgia is home to a diverse array of spider species but only a handful are considered medically significant. As a resident of the Peach State, it’s valuable to learn how to identify venomous spiders that may cross your path what to do if you encounter one, and proper first aid if a bite occurs. This comprehensive guide will provide key details on venomous spiders in Georgia, how to recognize them, tips for prevention, and vital response steps if you suspect a bite.

How Many Venomous Spider Species Live in Georgia?

Out of over 400 spider species found in Georgia, only 4 are regarded as dangerous to humans due to their potentially toxic venom. These 4 venomous spiders belong to different families and possess distinctive features

• Brown recluse spider – Loxosceles reclusa (Sicariidae family)

• Brown widow spider – Latrodectus geometricus (Theridiidae family)

• Southern black widow spider – Latrodectus mactans (Theridiidae family)

• Northern black widow spider – Latrodectus variolus (Theridiidae family)

While dangerous spiders capture public attention, the vast majority of Georgia’s spiders play harmless or even beneficial roles in local ecosystems. Only the brown recluse and widow spiders pose significant health risks with their bites. Let’s explore key identification details and habits of Georgia’s 4 venomous species.

How to Identify Venomous Spiders in Georgia

The Brown Recluse Spider

This light brown spider has a dark violin-shaped marking on its cephalothorax (fused head-thorax region). They measure 0.5-1 inch in body length and lack prominent stripes, spots, or spines. Brown recluses have 6 eyes arranged in pairs rather than the typical 8 eyes found in most spiders.

They construct irregular webs in secluded areas like attics, crawlspaces, and woodpiles. These nocturnal spiders actively hunt for prey at night. They deliver necrotic venom that destroys skin tissue, though serious reactions are uncommon.

The Southern Black Widow

This iconic glossy black spider has a bright red hourglass shape on the underside of its round abdomen. Females measure around 1.5 inches long while males are half that size. Juveniles can have white and red spots or stripes until maturing into the classic black widow appearance.

Black widows build tangled, messy webs in dark crevices like hollow logs, rodent burrows, and unused sheds. The potent neurotoxin in their venom can cause muscle cramps, nausea, and breathing difficulties, though antivenom makes bites rarely fatal.

The Northern Black Widow

Closely related to the southern black widow, northern black widows have a similar dark body with a reddish hourglass marking on the abdomen. However, the northern species has a broken rather than solid hourglass shape. These spiders average 1 inch in body length.

Northern black widows occupy habitats like stumps, woodpiles, and brush piles. Their venom isn’t as toxic as the southern black widow, but medical evaluation is still recommended after a bite. Children face higher risks.

The Brown Widow Spider

Ranging from light tan to dark brown or black, the brown widow has a vivid orange-yellow hourglass shape on its abdomen. Its legs are banded with black and brown. Brown widows reach about 1 inch long.

These spiders frequent protected spots like utility boxes, patio furniture, and playground equipment. While they have toxic venom, brown widows don’t inject large quantities when biting humans, so severe reactions are uncommon.

Tips for Preventing Venomous Spider Encounters

Risks from venomous spiders in Georgia are extremely low when proper precautions are taken. Here are smart strategies for avoiding encounters:

• Inspect shoes, clothing, and bedding before use since spiders may crawl inside. Shake out gloves and boots before putting them on.

• Wear gloves, long pants, and closed-toe shoes when working in the yard, clearing debris, or entering sheds and basements where spiders may lurk.

• Seal cracks and crevices where spiders may enter your home. Install screens on windows and doors and use caulk to plug gaps.

• Clear clutter like stacks of wood, piles of debris, and overgrown vegetation away from your home’s perimeter.

• Inspect surfaces before reaching blindly – glance before grasping ledges, railings, handles, or other hidden areas.

• Use caution when moving rocks, logs, and other objects spiders may be under. Gently prod the area first rather than grabbing directly.

What To Do if Bitten by a Venomous Spider

Most spider bites are harmless, but you should take quick action if you suspect a venomous species bite:

• Wash the bite with soap and water to reduce infection risk.

• Apply a cold pack or compress to the wound site to ease swelling.

• Capture or take a photo of the spider if possible for identification purposes.

• Monitor for signs of a serious reaction like severe pain, nausea, difficulty breathing, or spreading redness/swelling.

• Seek prompt medical care if concerning symptoms develop or a venomous spider is positively identified. Call 911 for critical reactions like breathing trouble.

• Keep the bitten extremity lower than the heart if able to slow venom flow. Avoid caffeine, excess activity, and medications unless prescribed.

By learning to identify Georgia’s few venomous spiders, exercising preventive habits, and following proper first aid steps, you can co-exist safely with these fascinating creatures while appreciating their vital ecosystem roles. Follow these tips for informed, sensible handling of any spider encounters around your home.
