Debunking Common Spider Myths
Missy Henriksen
The mere sight of a creepy crawly spider scaling a wall or lurking in a webbed corner can give
people the heebie-jeebies— but why? Over time, myths and misconceptions about spiders have
evolved throughout many cultures, resulting in a multitude of terrified reactions to this extremely
common pest.
While spiders can be a nightmare for homeowners, especially during the colder months, most
species are nothing more than a source of unexplained fear. From common myths to weird and
wacky misconceptions, the National Pest Management Association (NPMA) has debunked a few
well-known legends about this eight-legged arachnid and detailed the truths behind them.
Myth #1: The average person swallows about eight spiders a year when sleeping.
This urban legend has become one of the most widespread rumors on the Internet. But, fear
not – it’s false. According to Snopes.com, this myth was started when a columnist for a
computing magazine wrote an article in 1993 about a list of outlandish “facts” that were
circulating via email. In an effort to show that people will believe anything they read online,
the columnist made-up some of her own ridiculous facts, including the myth sited above. In
reality, it’s highly unlikely for a person to swallow even one live spider when sleeping.
Myth #2: People are never more than three feet away from a spider.
This myth originated in 1995 when arachnologist Norman Platnick wrote, “Wherever you
sit as you read these lines, a spider is probably no more than a few yards away.” With
more than 35,000 described species of spiders worldwide and about 3,000 in North
America alone, there may be some truth to this statement. However, many people argue
that it depends on where you are. For example, if you are standing in a grassy area,
there is likely be a spider crawling right next to you, but if you are on the top floor of a
skyscraper, the nearest spider could be hundreds of feet away.
Myth #3: All spiders spin webs.
Many people associate spiders with webs, but the truth is, not all spiders spin these silk
structures, which are used to catch their prey. In fact, several species of spiders use
different strategies for obtaining food. Wolf spiders, for example, catch their food by
hunting, while jumping spiders pounce on their prey.
Myth #4: Daddy longlegs are one of the most poisonous spiders, but their fangs are too
short to penetrate human skin
Daddy-long-legs are the subject of many urban legends. This specific tale has been
lurking around for years, but it’s completely false. Think about it – how can a spider inject
venom into the human body if its fangs are too short to pierce skin tissue? Arachnologists
at the University of California said, "There is no reference to any pholcid spider [read
"daddy-long-legs"] biting a human and causing any detrimental reaction… Furthermore,
there are no toxicological studies testing the lethality of pholcid venom on any
mammalian system.” Simply put, there no facts to support this widespread legend. If
you’re still not convinced, Jamie Hyneman and Adam Savage even debunked this myth in
2004 on their popular show, “MythBusters”.
Myth #5: All spiders are dangerous.
Spiders have lived amongst humans for centuries and most species don’t harm humans;
in fact, many species are beneficial to the environment. Spiders are predators, feeding
mainly on insects, so they help to reduce the amount of pests in homes and gardens.
While it’s true that all spiders have a venomous bite, only a few species are medically
dangerous. In the United States, the widow spiders and the recluse spiders are the only
groups that pose a health threat to humans. And, contrary to popular belief, most
tarantulas are harmless.
If you believed any of these spider myths, you’re not alone. There are many misconceptions
about spiders that give them a bad rap. However, it’s important for homeowners to take
preventative steps to keep the more dangerous species from gaining access to homes during the
winter months. The NPMA recommends storing clothes and shoes in plastic containers, sweeping
away webs around the home, and removing clutter from basements, attics and garages. If you
suspect a spider infestation, contact Pest Solutions at 540-288-8585 or 804-550-9005.
