The black widow spider is one of the most infamous arachnids in the world. With its shiny black body and striking red hourglass shape on the underside of its abdomen, it is easy to see why this spider has been the subject of many myths and legends. Perhaps the most pervasive myth about the black widow is that it is an aggressive, deadly predator that will attack humans without provocation. However, this myth is largely unfounded. In this article, we will explore the real nature of black widows and debunk this deadly myth.
What is a Black Widow?
Before we can answer the question of whether black widows are aggressive, we need to take a closer look at what exactly a black widow spider is. There are several different species of black widows, but the most well-known is the western black widow (Latrodectus hesperus) found in North America. These spiders are typically about half an inch to one inch in length and have distinctive shiny black bodies. The females of the species, which are the ones typically associated with the ‘deadly’ myth, have the characteristic red hourglass shape on their abdomens.
Are All Black Widows Dangerous?
While it is true that the venom of a black widow is neurotoxic and can be potentially dangerous, the reality is that most people who are bitten by a black widow will not experience serious health effects. In fact, according to the Centers for Disease Control and Prevention, only about 5% of people who are bitten by a black widow will experience severe symptoms such as muscle pain, nausea, and vomiting. Most people will only experience mild symptoms like redness and swelling at the bite site. Nonetheless, if you suspect you have been bitten by a black widow, you should seek medical attention immediately.
Are Black Widows Aggressive?
Now, let’s get to the heart of the matter. Are black widows aggressive? The short answer is no. In fact, black widows are shy and reclusive spiders that prefer to avoid contact with humans and other animals whenever possible. When threatened, they will usually try to run away rather than attack. It is only when they feel trapped or cornered that they will bite in self-defense. This means that the majority of black widow bites occur when a person accidentally disturbs or comes into contact with the spider’s web, such as when reaching into a pile of firewood or moving boxes in a garage.
What Should You Do If You Encounter a Black Widow?
If you happen to come across a black widow spider, the best course of action is to simply leave it alone. These spiders are beneficial to the environment because they help control populations of other insects like flies and mosquitoes. If you need to move them from your home or property, it is best to contact a professional pest control service to handle the job.
How Can You Identify a Black Widow?
Now that we know that black widows are not aggressive spiders, it can still be helpful to know how to identify them if you happen to come across one. The simplest way to tell if a spider is a black widow is to look for the characteristic hourglass shape on the underside of its abdomen. However, it is important to note that not all black widows have red hourglass markings. In some cases, the hourglass may be yellow or even white. Additionally, male black widow spiders and juvenile females may not have any hourglass markings at all.
What Do Black Widows Look Like?
As we mentioned earlier, black widows have shiny black bodies that are usually around half an inch to one inch in length. Female black widows have the red hourglass marking on the underside of their abdomens, while males and juvenile females may have different markings or none at all. Black widow spiders also have eight legs and two fangs that they use to inject venom into their prey or attackers.
Conclusion
Despite their fearsome reputation, black widows are not aggressive spiders that seek out humans as prey. In fact, they are shy and reclusive creatures that would much prefer to avoid contact with us altogether. The best way to stay safe around black widows is to simply leave them alone and let them go about their business. If you do need to relocate them from your home or property, it is always best to call in the professionals to handle the job.
