What Attracts Brown Recluse Spiders and How to Prevent Them

What Attracts Brown Recluse Spiders?

Brown recluse spiders are attracted to homes and yards mainly due to two primary reasons: harborage and sustenance.

They seek out man-made structures, particularly those with holes, cracks, and gaps, which provide suitable hiding places and nesting sites.

Additionally, these spiders are attracted to areas with a steady supply of food, such as bugs and other small insects.

They are known to reside in storage areas, attics, basements, closets, bedrooms, and other secluded spaces.

To prevent contact with brown recluse spiders, it is important to be cautious when handling stored items, use sealed plastic totes for storage, shake clothing and footwear before use, and regularly clean and declutter spaces where spiders may reside.

If an infestation is suspected, it is best to contact a licensed pest management professional for effective removal.

Did You Know?

1. Brown recluse spiders are not actually attracted to clutter or disorder, as commonly believed. Instead, they are drawn to areas with less foot traffic that offer them shelter and hiding places.
2. These spiders are mainly attracted to warmth and moisture, which makes basements, attics, and crawl spaces common places for them to seek refuge.
3. Brown recluse spiders are known to have a unique hunting behavior, unlike most spiders. They actively search for prey instead of constructing webs to catch it.
4. The venom of a brown recluse spider contains a protein that can cause necrotic skin lesions in some individuals, and it is estimated that only a small percentage of bites actually result in these serious symptoms.
5. Contrary to widespread belief, brown recluse spiders are not native to all areas of the United States. They are primarily found in the central and southern regions of the country, particularly in states like Texas, Oklahoma, and Missouri.

Significance Of Brown Recluse Spiders Infestation In Homes

The presence of multiple brown recluse spiders in a home is not something to be taken lightly. These spiders are known for their venom, which possesses potent necrotic properties. While brown recluse spiders rarely bite humans, their bites can be a cause for concern. It is not uncommon for a home to have several dozen brown recluse spiders, as they are comfortable living with humans permanently. In infested homes, the numbers of brown recluse spiders can reach upwards of 5,000. Given their poisonous nature and potential medical threat, having a brown recluse infestation is a significant problem that requires immediate attention.

Characteristics And Behavior Of Brown Recluse Spiders

Brown recluse spiders are small arachnids, not much larger than a quarter. They are characterized by a dark violin shape on their back, although it can be difficult to discern on such a tiny spider. One distinguishing feature is their visibly hairless appearance.

These spiders are nocturnal and reclusive, preferring to hide in secluded areas during the day. As a result, homeowners may find them in:

  • Storage areas
  • Attics
  • Basements
  • Closets
  • Bedrooms
  • Boiler rooms
  • Heat tunnels
  • Crawl spaces
  • Garages
  • Outdoor debris or woodpiles

They are particularly attracted to cardboard and prefer stillness. Tangled spiderwebs in low, out-of-the-way places can serve as indicators of their presence in a home.

Symptoms And Effects Of Brown Recluse Spider Bites

While bites from brown recluse spiders are rare, they can have severe consequences. The initial bite is often undetected due to its painless nature. However, localized pain and itching can develop within a few hours, with the intensity varying from mild to intense, lasting up to eight hours. Most bites result in a small wound with a blister or ulcer in the center. A rash is usually associated with a recluse bite. Furthermore, the tissue surrounding the bite may undergo necrosis, or tissue death. In some cases, individuals may have a systemic response to the bite, experiencing symptoms throughout the body, such as chills, fever, restlessness, difficulty sleeping, joint pain, nausea, and vomiting. Given these potential effects, it is crucial to monitor any brown recluse bite and seek medical attention if necessary.

Indicators Of Brown Recluse Spider Presence In A Home

If you suspect the presence of brown recluse spiders in your home, there are key indicators to look out for.

Preventive Measures To Avoid Contact With Brown Recluse Spiders

To reduce the risk of encountering brown recluse spiders and minimizing the chance of a bite, there are several preventive measures you can take:

  • Evaluate your home for any holes, cracks, or gaps that may serve as entry points for the spiders.
  • Seal these entry points to significantly reduce the chance of an infestation.
  • Be cautious when opening stored boxes, as brown recluse spiders may be hiding inside.
  • Store items in sealed plastic totes to prevent spiders from accessing them.
  • Before using clothing, towels, or footwear, make a habit of shaking them to remove any hidden spiders.
  • Avoid leaving clothing on the floor, turn down bedding before getting into bed, and remove skirts from beds to minimize areas where spiders could hide.
  • When entering dark and secluded areas, use a flashlight to detect any potential spiders.
  • When moving wood or debris in your yard, wear gloves to protect yourself from potential bites.
