The Different Types of Spiders That Can Be Found in Florida

What to Do About An Infestation

Perhaps one of the most polarizing creepy crawly creatures in the insect world is the spider. A popular image for Halloween decoration, these are some of the most well-known insects in the world. Some people keep them as pets while others screech at the sight of the smallest arachnid. Whether you love them or hate them, spiders can cause problems around your home if they’re left to thrive. These multi-legged pests can be both a help and hinderance at properties in Florida, but if you have an infestation, they can cause more harm than good. Spiders come in two very important categories: non-venomous and venomous to humans though either can cause issues around your property. 


One of the most common spiders in Florida, the wolf spider, is thankfully non-venomous, though some people mistake it for the venomous recluse. The wolf spider gets its name from its hairy appearance. This spider is a hunter and instead of spinning a web, they disguise themselves and ambush their prey. They are larger than many common house spiders and their legs are more spread out which makes them faster. While these spiders aren’t deadly to humans, if you get bitten, you could experience itching and swelling around the bite. Wolf spiders can grow up to two inches in length and typically live outdoors under ivy or the like. However, if you find them in your home, they’ll be scurrying across the floor and walls.

Another common spider found in Florida, and across much of the U.S., is the daddy long leg. Also known as a cellar spider, these common pests are characterized by their incredibly long, delicate legs. They like hanging out in windowsills, in garages, and in basements and feed on insects as well as other kinds of spiders – which can be beneficial. They are not venomous to humans but can cause alarm through their appearance, especially if they’re found in large numbers! Stumbling upon a daddy long legs nest can be quite shocking.

While these common spiders are non-venomous to humans, they can still be a nuisance if they infest your property.


While all spiders have venom that they use to paralyze their prey, only a handful of spiders have venom that’s toxic to humans. Two of the most common dangerous spiders can be found in Florida: brown recluse and widow spiders. Having an infestation of these spiders in your home can not only be a nuisance but they can be deadly.

Brown recluse spiders can be identified by a dark brown mark shaped like a violin on their backs. These venomous spiders range in color from tan to dark brown and vary in length from a quarter of an inch to a half inch. They thrive in warm, dry, dark environments like closets or basements – depending your level of moisture control. Shockingly, they can live for up to a year without food or water. Their venom can cause severe reactions in children and the elderly or those with preexisting conditions and compromised immune systems. Unfortunately, the bite can frequently go unnoticed at first before it begins to turn red and swell. From there the affected area may be come dry and produce a blister at the center of the bite and also cause other issues that can require extensive medical treatment. While bites from these spiders typically aren’t deadly, they can be quite unpleasant and dangerous.

Another common poisonous spider in Florida is the black widow. This might be the most well-known dangerous spider in the insect world. The black widow can be identified by a red, hourglass-shaped spot on the abdomen. Many other spiders can be mistaken for the black widow, but it’s always better to be safe instead of sorry when it comes to these dangerous creatures. Their name doesn’t come from their venomous nature but instead the belief that females of the species eat males after mating, though this is a rare occurrence. Though their venom is toxic and is reported to be even stronger than that of a rattlesnake’s, the bites rarely cause death. Thankfully, these spiders aren’t aggressive and only bite when threatened. Black widows seek out protected spots to live like decks, barns, woodpiles, and sheds.

When You Have an Infestation

Having an infestation of either non-venomous or venomous spiders can be a problematic event. Non-venomous spiders can simply be a burden because of their unsettling appearance or an annoyance because of their non-lethal bites. Having a plethora of venomous spiders on your property or in your home can be incredibly dangerous. Most kinds of spiders crave dark spaces where they can either build their webs, nests, or simply hide in a crevice. If you have an infestation it will likely be in a basement or garage. Signs of infestation around the home include abandoned webs or shed spider skins. If you have an infestation of flies or mosquitos, spiders may seek out your property due to the ample food source. The best way to get rid of spiders is to get rid of their food source, so a variety of pest control services may be needed to handle the complete issue. Trying to rid your property of pests on your own can be dangerous and ineffective. Receiving multiple spider bites while trying to handle the problem can be deadly. Leave these types of infestations to the professionals, like those at Impact Pest Elimination. No one wants to try several times to get rid of these creepy creatures and working with a trusted pest control specialist will set your mind at ease.
