Sowbug killer spiders, also known as Dysdera crocata, are a species of spiders known for preying on small, land-based crustaceans called sowbugs and pillbugs. These spiders can be easily identified by their reddish-brown coloration and their elongated, cylindrical bodies.
Although sowbug killer spiders possess large, strong fangs used for hunting, their bites are not typically harmful to humans. Generally, they only bite when they feel threatened or cornered.
As they are predators of sowbugs and pillbugs, these spiders indirectly serve as a natural pest control method in gardens and landscapes. However, they may have some drawbacks, such as their potential to spread indoors and create webs in undisturbed areas.
Sowbug Killer Spider Overview
Identification and Physical Features
The Sowbug Killer, also known as the Woodlouse Hunter (Dysdera crocata), is from the Araneae order within the Animalia kingdom, belonging to the Arthropoda phylum, Arachnida class, and Dysderidae family. These spiders are known for their distinctive features:
- Six eyes
- Long legs
- Coloration: brown, tan, red, purple, orange, or yellow
Habitat and Distribution
Dysdera crocata spiders can be found in various environments, including:
- Under rocks
- Among leaf litter
- In gardens
- Inside garages
These spiders thrive in moist, dark spaces and are primarily found in North America and Europe.
Feeding Habits and Prey
Sowbug Killer Spiders are experts in preying on specific creatures such as:
- Pillbugs
- Mites
They utilize their long legs to catch and immobilize their prey effectively.
Bites and Symptoms
Causes of Bites
Sowbug killer spiders, like most spiders, usually bite humans only when they feel threatened or accidentally disturbed.
Some examples of situations leading to bites:
- Unknowingly putting on a piece of clothing with a spider inside
- Accidentally touching or stepping on a spider
Signs and Symptoms of Bites
A sowbug killer spider bite can cause various symptoms. Some common ones are:
- Itching
- Pain
- Swelling
- Redness
In some cases, bites from more venomous spiders like the brown recluse or the black widow can lead to more severe symptoms, such as:
- Muscle pain or cramping
- Headache
- Increased sweating
- Difficulty breathing
Severity and Potential Complications
The severity of a spider bite depends upon the type of spider and the individual’s reaction to the venom. In general, sowbug killer spider bites are not considered dangerous and typically cause only mild discomfort.
However, complications can arise in case of bites from venomous spiders such as brown recluse or black widow spiders. These can include:
- Allergic reactions
- Skin ulcers
- Scarring
- In severe cases, death (very rare)
Dangerous Spider Comparisons
Here’s a comparison table of some dangerous spiders:
Spider | Venom | Symptoms | Severity | Remarks |
---|---|---|---|---|
Brown Recluse | Necrotizing venom | Pain, redness, blisters, necrosis | Moderate to severe | Can cause severe skin damage |
Black Widow | Neurotoxic venom | Severe muscle pain, cramps, abdominal pain, tremors | Moderate to severe | Antivenom available |
Sowbug killer spider | Mild venom | Itching, pain, swelling, redness | Mild | Not considered dangerous |
Overall, sowbug killer spiders are not as dangerous as the venomous brown recluse or black widow spiders, and their bites usually cause minor symptoms.
Treatment and Medical Care
First Aid for Bites
If you’re bitten by a sowbug killer spider, follow these first aid steps:
- Wash the area well with soap and water.
- Apply an ice pack or wet compress to reduce swelling.
- Take over-the-counter pain medicine for pain relief.
- Consider using antihistamines for severe swelling. source
When to Seek Medical Care
You should seek medical care if you experience:
- Fever or chills
- Nausea or vomiting
- Severe pain or worsening pain
- Signs of infection (e.g., increased redness, warmth, pus)
- Black widow spider bite symptoms (e.g., muscle cramps, abdominal pain, difficulty breathing) source
Medical Treatment Options
Doctors may prescribe the following treatments, depending on diagnosis and symptoms:
- Antibiotics to treat or prevent skin infections
- Pain relievers for moderate to severe pain
- Antihistamines to reduce itching and swelling
- Antibiotic ointment for skin sores and blisters source
Pros and Cons of Medical Treatments
Treatment | Pros | Cons |
---|---|---|
Antibiotics | Effective against infections | Potential side effects, antibiotic resistance |
Pain Relievers | Reduces pain | Side effects, potential for addiction |
Antihistamines | Reduces itching and swelling | Side effects, potential for drowsiness |
Antibiotic Ointment | Helps prevent infections | Requires regular application |
Remember to always consult a healthcare professional for proper diagnosis and treatment of spider bites.
Prevention and Safety Measures
Minimizing Sowbug Killer Spider Encounters
Sowbug killer spiders, also known as woodlouse spiders, are typically found in damp areas like basements, gardens, and woodpiles. To minimize encounters with these spiders:
- Keep woodpiles away from the house
- Remove dead leaves and debris from the yard
- Seal gaps and cracks in walls and foundations
By creating a clean and dry environment, you will be less likely to encounter these spiders.
Protective Gear and Precautions
When working in areas where dangerous spiders may be present, such as in gardens or basements, it is important to wear protective gear:
- Gloves
- Long-sleeved shirts
- Long pants
Additionally, be cautious when reaching into dark or hidden spaces where spiders may be hiding. Using a tool like a stick to probe areas before reaching in can help prevent bites.
Bug Control Recommendation Tool
Home and Garden Maintenance
Keeping your home and garden well-maintained is essential in preventing sowbug killer spiders and other dangerous spiders from nesting. Some tips for maintenance include:
- Regularly cleaning basements and other damp areas
- Trimming overgrown vegetation and removing leaf litter
- Removing potential hiding places like woodpiles and rocks
By following these guidelines, you can help reduce your risk of encountering sowbug killer spiders or other dangerous spiders.
Comparative table between Sowbug Killer Spider and other dangerous spider (e.g., Redback Spider):
Feature | Sowbug Killer Spider | Redback Spider (Australia) |
---|---|---|
Prevalence | Basements, gardens | Australia, around the home |
Distinct Body Feature | Large red fangs | Red hourglass shape on the abdomen |
Type of Bites | Painful but harmless | Painful, can cause cramping |
Home and Garden Maintenance Importance | High | High |
By understanding the differences between various dangerous spiders, you can better assess the risk in your environment and take appropriate safety measures.

As of this morning both are still alive but have separated now! Woodlouse hunters are possibly immune to the venom of other woodlouse hunters? I have seen other woodlouse spiders in the past kill adult wolf spiders with single bites in less than 20 seconds.
We are very happy to hear there were no casualties.
naturally like your website but you have to test the spelling on quite a few of your posts. A number of them are rife with spelling problems and I in finding it very troublesome to inform the reality on the other hand I’ll certainly come back again.
We do not correct the spelling nor grammatical errors in the letters we post from our readership, however we do strive for accuracy with our responses, but we are not perfect. We do not have an editor to check our accuracy prior to posting.
Does finding two in my house an indication of wood eating pests?
Woodlice do not eat wood, so finding Woodlouse Hunters is no indication of the state of the wood in your home.
Haven’t tried the Clark zapper yet, right now it’s just an idea.
I was looking at the conventional bug zapper in Home Depot, and noticed it has about 3/8″ spaces between the bars, this won’t work unless I can find a way to make it small enough so a mite can’t slip through it, or devise something that will fry them if they land, or fall, on it?
