Are The Spiders In Denver Dangerous To Have In Your Home? | Absolute Pest Control


Denver is known for many things: the Denver Broncos, the Denver Nuggets, and many historical landmarks and museums. However, who would have guessed this forward-thinking city would be notorious for housing some of the world's scariest and most venomous spiders?

Some common types of spiders found in Denver homes include common house spiders, jumping spiders, and wolf spiders. Wolf spiders aren’t venomous to humans but pack a painful bite. The two most venomous spiders in the area are the black widow and brown recluse spiders. If bitten by either of these species, you should seek medical help immediately, as their bites come with extreme pain, health complications, and even death.

No one wants spiders living in their homes, despite their role in our ecosystem. However, if you recognize a spider problem, you likely have other pest problems. Flies, ants, and mosquitoes are all critters that spiders love, so if you see spiders, they’re in your home because you have food sources for them.

Whether you physically see spiders in your home or not, regularly treating your house for pests is always a good preventative tactic. At Absolute Pest Control, we will treat the interior and exterior of your home for spiders to safeguard your home from such hazardous pests. Additionally, we never make you sign a contract for our services. That’s how confident we are in our quality of services.

As your local Denver pest control experts, we encourage you to contact Absolute Pest Control at the sight of a single spider. To learn more about our residential pest control services, call us today.

What Do Spider Bites Look Like?

People may respond differently to various types of spider bites. Even if you're talking about a single species of spider, like the brown recluse, its bite could result in multiple symptoms, ranging from a tiny bump resembling a pimple to a lesion that looks like rotting flesh. Different spiders and their bites do, however, result in different reactions. For instance, black widow and brown recluse bites are so distinct that there's no way one could be mistaken for the other.

However, you can't deny that all their bites have predictable characteristics in relation to other non-venomous spiders in the area, such as hobo spiders, common house spiders, and other domestic species.

Generally speaking, a spider bite resembles a bee sting; a sharp prick of pain followed by a red, often inflamed skin lump that may hurt or itch for a few days and then subsides. However, there are distinctive physical characteristics in venomous spider bites.

Take a look at some of the physical features of common spiders in Denver:

  • Brown recluse bites are painful and can range in appearance from small blisters to large, rotting sores.
  • Black widow bites can occasionally result in skin lesions, ranging from tiny red marks to aggravated, streaky, red, and inflamed patches of skin that may also contain pus.
  • Domestic spiders such as the wolf, hobo, and common house spiders will leave a swollen, red, painful lump at the bite site.

If you think you’ve been bit by a spider and recognize some of these signs on your body, get in touch with your healthcare provider, especially if your symptoms worsen or you experience a reaction that affects your whole body. Although it is extremely unlikely that a spider bite will result in a life-threatening or fatal reaction, you may still require medical diagnosis and treatment.

Are Spider Bites Typically Dangerous To Ignore?

Although the majority of spiders in the United States are non-venomous, some bite and leave a painful after-effect, the most effective way to determine whether you should be concerned about a spider bite is to see the spider that bit you. Tarantulas, jumping spiders, brown recluses, and black widows might also need additional medical attention. If you didn't see the spider, the symptoms might still help to assess your risk. 

A benign spider bite typically results in a red bump that may be itchy or swollen. Bites from venomous spiders like the brown recluse and black widow can result in excruciating pain, body aches, swelling, chills, sweating, and cramping. You should see a doctor if an itchy rash worsens, you experience pain around the bite, or the bite starts to blister.

You should be most concerned about the brown recluse and black widow spiders.

Symptoms of a bite from a black widow spider include severe cramping or rigidness in the abdomen, appendicitis or an appendix rupture, vomiting, tremors, sweating, and nausea can happen separately or at the same time. Your chest, back, or stomach may also experience redness, pain, or swelling around the bite site. Symptoms generally last for one to three days.

A brown recluse spider bite can cause fever, chills, and body aches. The bite mark may have a red ring around it and a pale center that darkens to blue or purple, and the pain typically worsens over the first eight hours following the bite. Shortly after, the bite slowly becomes an open sore (ulcer) and causes the surrounding skin to deteriorate (necrosis).

If a spider bites you and you're unsure if a harmful spider caused the bite, seek medical attention immediately, especially if you experience difficulty breathing or swallowing, feel the bite wound getting worse, or have severe abdominal pain cramps.

Remember, if you’ve been bitten by a spider or think a spider may have bitten you, never ignore it, despite most spider bites being harmless. Denver houses two of the most venomous spiders in the world. If you suspect either of them has bitten you, seek medical attention immediately and call Absolute Pest Control to get your spider removal services started quickly.

How Can I Tell The Bite I Have Is A Spider Bite?

You probably won't know if it's a spider bite unless you catch it or see it. Skin irritated, swollen, and reddened is a common reaction to being bitten by many insects. However, aside from seeing a spider scurrying away after a bite, here are a few other signs and symptoms.

  • Noticeable skin discoloration: A spider bite will likely result in a rash that differs in color from the rest of your skin. Your skin tone and the type of spider that may have bitten you both play a role in this. For instance, a harmless spider bite will probably result in red or pink discoloration if you have lighter skin. A nonvenomous animal may appear reddish brown if you have darker skin.
  • Two fang-like puncture marks: Two puncture marks may be visible if you look closely at the bite site. These are sometimes easy to see with the naked eye and sometimes difficult.
  • Swelling: Swelling is typical after being bitten by a spider or stung by any insect. When a spider bites, the skin is harmed by the fangs, causing swelling and inflammation. The severity of either condition ultimately depends on how your body reacts to the bite. Even with a nonvenomous spider bite, swelling can happen, but it will probably be worse if it is venomous.
  • An uncomfortable bump or a rash: Depending on the kind of spider that bit you, you might develop a rash. You might only have a small, itchy bump on your skin if a non-venomous spider bit you. Depending on the setting, it might even go unnoticed.

However, suppose a venomous spider like a black widow or a brown recluse has bitten you; the bites can result in necrotizing wounds. In that case, your rash won't go away and might even necessitate a trip to the emergency room. It may appear as a pus-filled blister, a patch of thickened skin, or a bruise with a bull's-eye pattern and two dark rings in the center. These skin symptoms can occasionally take time to manifest. It might be seven to 14 days after a brown recluse bite before noticing an ulcerated wound.

Unfortunately, Denver has different spider species. That is why it’s crucial to protect yourself, your family, and your pets from harmful spiders with preventative spider control services from Absolute Pest Control.
