Florida’s Venomous Spiders
I am one of those people who is not afraid of spiders. In fact, I like them a lot. Therefore, I feel like I need to be educated about the ones that would pose a danger to me if I were to pick them up and be bitten. I was looking at an article by G. B. Edwards of the Florida Department of Agriculture & Consumer Services and he says that only two main types of venomous spiders are in the state: widow spiders and recluse spiders.
Widows can be native to Florida. Of the four species of this type of spider, three are native. The fourth species has been introduced. It turns out that widow spiders are not native to Florida at all, but there are three species that are occasionally found here.
Since both of these kinds of spiders generally stay where they are no easily seen, the article recommends that you wear gloves when doing things like lifting firewood or reaching into a storage box or your BBQ grill.
A widow’s bite releases venom that acts systemically and moves through your lymphatic system. You might notice “intense pain, rigid abdominal muscles, muscle cramping, malaise, local sweating, nausea, vomiting, and hypertension.” The symptoms can last three to five days if not treated, but treatment is easier than you might think. Not only will an anti-venom work, but so will calcium gluconate – with can be obtained at the drug store inexpensively.
Recluse spiders are hunters and more aggressive than widows, but still only usually bite humans when trapped against the skin, like when you roll over onto one in bed or put on clothing where one is hiding. Their bites cause symptoms within two to four hours, generally making a swollen, painful blister at the bite site that is reddish in color and surrounded by blue. This is called a ‘bull’s-eye’ pattern. If it turns purple, the skin around the bite is becoming necrotic, which means it will eventually turn black and the cells will die, leaving a pitted, scarred area.
When I lived in Gainesville, we had a lot of brown recluse spiders in our wooded yard. We often found them on our screened porch. Alachua County is one of the places the brown recluse is often found. We resorted to putting out a trap, because my daughter was a toddler at the time and liked to run about touching things and exploring the environment. Of course, I still felt safer being right with her so I could monitor her actions.
