SPIDERS
What are spiders?
Spiders are arachnids, a class of joint-legged invertebrates that also includes scorpions, ticks, and mites. Unlike insects, which have six legs, spiders have eight legs, making them easily distinguishable.
Key features of spiders include:
Body Segmentation:
Spiders have two main body parts: the cephalothorax (a fused head and thorax) and the abdomen. They lack wings and antennae.
Silk Production:
Spiders are known for producing silk, a proteinaceous substance extruded from spinnerets located at the rear end of their abdomen. They use silk for various purposes, including building webs, creating egg sacs, and as a means of transportation.
Venomous Fangs:
Most spiders have venomous fangs (chelicerae) that they use to inject venom into their prey. However, the vast majority of spiders are not harmful to humans, and their venom is primarily used to immobilize or digest their prey.
Predatory Behavior:
Spiders are carnivorous and primarily feed on insects and other small arthropods. They play a crucial role in controlling insect populations and maintaining ecological balance.
Life Cycle:
The life cycle of a spider typically involves hatching from an egg, passing through several molts as they grow, and reaching maturity.
Variety of Species:
There are thousands of known spider species, and they exhibit a wide range of behaviors and adaptations. Some spiders build elaborate webs to catch prey, while others are active hunters that do not use silk for trapping.
Common examples of spiders include orb-weavers, wolf spiders, jumping spiders, and tarantulas. While some people may fear spiders due to their appearance and the presence of venom in some species, the majority of spiders are harmless to humans and are beneficial in controlling insect populations.
Are spiders dangerous?
In Utah, most spiders are not considered dangerous to humans. While there are some venomous spiders in the region, their bites are typically not harmful unless a person is allergic or sensitive to the venom. It's important to note that spiders usually bite only in self-defense and are not aggressive toward humans.
Two spiders in Utah that are worth mentioning due to their venomous nature are the black widow spider and the hobo spider.
Black Widow Spider:
Black widows are known for their distinctive appearance, with a shiny black body and a red or orange hourglass-shaped mark on the underside of the abdomen. The bite of a black widow can cause pain, muscle cramps, and other symptoms, but fatalities are extremely rare. Seek medical attention if bitten, especially if you experience severe symptoms.
Hobo Spider:
The hobo spider has a funnel-shaped web and is generally brown with distinct markings. While it was once considered medically significant, recent research suggests that its bite is less harmful than previously believed. Nonetheless, if bitten, it's advisable to seek medical attention to ensure proper care.
Most other spiders in Utah are harmless to humans, and their bites generally cause mild, localized reactions. It's important to avoid provoking spiders and to take precautions, such as shaking out clothing and shoes before wearing them, to reduce the risk of accidental bites.
If you encounter spiders in or around your home and are concerned, give us a call! We can help identify the species and assist with appropriate control measures. Additionally, if you are bitten and experience severe symptoms, seek medical attention promptly.

How do I get rid of spiders?
Getting rid of spiders involves a combination of strategies to eliminate existing spiders and their webs and to deter new spiders from entering your living space. Here are some steps you can take:
Regular Cleaning:
Keep your home clean and free of clutter. Regularly dust and vacuum to remove spider webs, egg sacs, and any potential prey insects.
Seal Entry Points:
Seal cracks, gaps, and openings in windows, doors, and walls to prevent spiders from entering your home. Pay attention to areas where utilities enter the house.
Remove Hiding Places:
Clear away any debris, woodpiles, or other potential hiding places near your home. Spiders may use these areas as shelters.
Outdoor Lighting:
Change outdoor lighting to yellow sodium vapor lights, which are less attractive to insects. Reduced insect activity around your home can make it less appealing to spiders.
Professional Pest Control:
If the spider infestation persists or is severe, give us a call. We can assess the situation, identify the spider species, and apply targeted treatments.
How can I prevent spiders in the future?
Although it is completely normal to occasionally have a spider or two in your home, it is important to remember that spiders eat other insects. The best and easiest way to prevent spiders is by controlling the insect population in and around your home. Regular pest control services are important in preventing insect and spider infestations.
It's especially common to see spiders inside your home during winter months, as they like to escape the cold. A winter-time pest treatment inside your home can be helpful.
