There are approximately 3,000 different types of spiders that call North America and the United States home. During the fall many of these spiders are maturing and are actively looking for food and mates, which sometimes means they find themselves unwittingly entering homes and businesses. This is why you may be seeing more spiders than usual during the fall. The good news is that a majority of spiders are not only harmless to humans but are beneficial!
Spiders feed on insects and pests that can cause disease, like mosquitoes, fleas, and cockroaches, and cellar spiders will even eat black widow spiders. However, there are a handful of spiders that are dangerous and whose venom is not only harmful but can be fatal to humans. Most spiders are not aggressive and will only bite if provoked or in defense, which is why it is important to never touch spiders, especially if you think they are dangerous. Identifying these dangerous spiders can help prevent injury.
The 2 most dangerous types of spiders in the United States are the Black Widow and Brown Recluse spiders, with Hobo Spiders and House Spiders receiving 2nd runner-ups due to the painful,though non lethal side effects of their bites.
Considered the most venomous spider in the world (their venom is 15x stronger than that of a rattlesnake), Black Widows are found on 6 continents but in the United States they are predominately found in the southern region of the country. Females can be identified by the reddish dot or hourglass shape on their abdomen and can be aggressive.
Also called Violin Spiders, Brown Recluse spiders can be identified by their light to dark brown coloring and characteristic dark brown violin marking on their backs (hence their nickname). In the United States, they are found from east coast to west coast, favoring the central and southern regions of the country. They will bite in defense and can be aggressive. Though they tend to prefer dark recesses, males can have wanderlust compared to their female counter parts, ending up in shoes or other attire.
What Can You Do To Keep Spiders Out?
To minimize spiders getting into your home PestWorld.org advises that “the best way to prevent spider infestations is to remove any possible harborage sites. Spiders are more likely to take refuge in dwellings during the colder months and will gravitate toward dark, undisturbed nooks and crannies. Therefore, homeowners should keep garages, attics and basements clean and clutter-free, avoid leaving clothing and shoes on the floor and seal any cracks or crevices around the home.”
