Dangerous Spiders Found In Las Vegas
There are over 35,000 species of spiders in the world, with over 3,000 residing in North America—most of which are harmless to humans and can even be beneficial. However, two species are known to be venomous and present a threat to humans, and unfortunately, both live in Las Vegas.
How to Identify Dangerous Spiders in Las Vegas
The two spiders in the U.S. known to be harmful to humans are the brown recluse and the black widow. Brown recluse spiders are light to dark brown with an even darker violin shape on their back. They range in size from about ¼ to ½ an inch in length.
Black widow spiders have round bodies that are shiny and black. A reddish hourglass figure on their abdomen is their main identifying feature. Black widows are much larger than brown recluse spiders, growing to over an inch long.
What’s So Dangerous About Brown Recluse and Black Widow Spiders?
Both the brown recluse and the black widow tend to be solitary spiders. They like living in warm, secluded areas and would rather avoid contact with humans. What makes them dangerous then? Both have venom that is toxic to humans. You’re unlikely to encounter one of these spiders, but if they get into or are around your home, you could end up accidentally coming into contact with one. When they feel threatened, both of these spiders will bite.
Brown recluse bites cause necrosis of the tissue around the bite. Symptoms include stinging, pain, and swelling at the bite site, along with fever and restlessness. After about a week and a half, the dead tissue starts to slough off, leaving ulcers, and even exposed muscle and bone.
Black widow bites are immediately painful. Symptoms of a bite include pain, fever, nausea, and increased blood pressure. While brown recluse and black widow spider bites are rarely fatal, they do require immediate medical attention.
How to Keep Dangerous Spiders Out of Your Las Vegas Home
Keeping dangerous spiders away from your home is the best way to avoid being bites. Below are several things you can do to prevent brown recluse and black widow spiders from getting into your house.
Look carefully around the outside of your home and seal all possible entry points. These include cracks in your foundation, gaps around windows and doors, holes in your siding, and damage to your roof.
Limit moisture in and around your house. Both of these spiders like damp areas, so reducing moisture in your yard, as well as ensuring that the inside of your home has low humidity, will help.
Eliminate food sources. Spiders often come into homes not because they’re looking for a warm place to live, but because they’ve followed a food source inside.
Since spiders eat insects, if you end up with a spider infestation, it could mean that you have another pest problem. Avoid this fate by getting year-round pest control from Red Rock Pest Control.
