Sometimes, what seems like an irrational fear is actually entirely justifiable. Although it's true that spiders don't go out of their way to attack humans, it's equally valid that certain species of arachnid possess a very powerful and dangerous bite. It's also true that these dangerous spiders will bite when they feel cornered or provoked. That's why it's important to know how to identify them and what to do once you have done so. Read on to learn everything you need to know about the most dangerous spiders common to our area, including the key to complete pest control in Caldwell

Two Types Of Dangerous Spiders You Can Find In Caldwell

The two main species of spider that pose significant problems for Caldwell homeowners are the brown recluse and the black widow. Both of these arachnids pack a potent venom behind those fangs, but each one goes about it a little differently. They can sometimes be mistaken for less dangerous species, so it's important to commit their distinguishing characteristics to memory.

Black widows are about an inch and a half long. They are web-spinning spiders with black carapaces and a signature red hourglass symbol on the underside of their abdomens.  Black widows prefer stealth and seclusion, often weaving their webs inside old boxes, unused tires, and in the corners of attics or basements.

Brown recluses are smaller, 1/4 to 1/2 inch, and actively hunt for their food, using their webs mostly to rest rather than catch insects. Aptly named, these arachnids bear a brown carapace, with a darker fiddle pattern on their cephalothorax (the portion of the body to which the legs attach.) More active than the black widow, these spiders will hide in laundry, in sheets, or will be found scurrying across the floor as they hunt.

What You Should Know About Dangerous Spider Bites

As a rule, spiders tend to avoid people– even dangerous spiders. We're simply so much larger than them that they'd prefer not to waste the venom, but when they feel pressured, they won't hesitate to defend themselves. Both black widows and brown recluses inflict a dangerous bite to humans, usually painful, and often require medical attention, but the symptoms are somewhat different between the two.

A black widow bite will be painful as soon as it happens, gradually spreading as an ache throughout the body with a growing fever and sense of nausea.  In severe cases, the person may also develop a fast heart rate and high blood pressure. Symptoms most often appear 30 minutes to 2 hours after the bite. They may last for 24 to 72 hours.

A brown recluse bite will gradually become painful as the affected area reddens, swells, and blisters.  If the area around the bite becomes more purple in color between 12 and 24 hours after the bite, skin death will likely occur. This is known as necrosis. If necrosis occurs, it can take several weeks or even months for the wound to completely heal.

If you suffered a bite by either of these spiders, or something you can't identify, and you begin to experience noticeable symptoms such as these, you should seek medical attention as soon as possible!  Bring the spider that bit you for identification, if possible, so the proper antivenom can be administered.
