Black Widow Spiders

Easily recognizable due to the hourglass shape females have on their abdomen, the black widow is one of the most feared spiders in the world.  That’s because its venom is 15 times stronger than the venom of a rattlesnake! If a black widow bites you, you can expect nausea, muscle aches, and possible diaphragm paralysis, making it difficult to breathe. While most people do not experience long-term, severe damages or death due to a black widow bite, the bites can be fatal to small children, people who are already ill, or the elderly. Black widows tend to bite only in self-defense.

Brown Recluse Spiders

These range in color from white to dark brown or even black. They are medium-sized and tend to have dark markings on their cephalothorax that looks like a violin. Brown recluses are not indigenous to Florida, but you may require medical attention if a brown recluse spider bites you.

Grass Spiders

Brown or gray in coloring, grass spiders have light and dark stripes close to their head. They build webs in the shape of a funnel so they can use it as a retreat. Grass spiders tend to construct webs in areas of tall grass or on the ground near window wells, foundations, steps, and low shrubs, but sometimes wandering males will find themselves indoors as they search for a mate. The bites of grass spiders are low risk to humans.

Also called golden orb-weaver, yellow garden orb-weaver, corn spider, and the writing spider, these spiders are easily identifiable by their large size and distinct appearance. They have beautiful yellow and black coloring on their abdomens with alternating bands of orange and black on their legs. If you disturb a female black and yellow garden spider in her web or otherwise threaten the spider, you may get bitten. Symptoms of garden spider bites include discomfort and mild swelling.
