Found a Brown Recluse in My House? Here's What You Need to Know

Discovering a brown recluse spider in your home can be unsettling. These elusive arachnids are known for their venomous bites and reclusive nature. Understanding what attracts them, their behaviors, and how to identify their nests can help you take proactive steps to protect your home.​

What Attracts Brown Recluse Spiders to Your Home?

Brown recluse spiders are drawn to environments that offer shelter and food. They prefer dark, undisturbed areas such as basements, attics, closets, and crawl spaces. Cluttered spaces provide ample hiding spots, making storage boxes, piles of clothes, and unused furniture ideal habitats. Additionally, homes with an abundance of insects serve as a food source, further attracting these spiders. ​

Brown Recluse Spiders on Ceilings: Myth or Reality?

While it's uncommon, brown recluse spiders can be found on ceilings. They are primarily ground dwellers but may climb walls or ceilings in search of prey or new hiding spots. Their presence on ceilings often indicates a larger infestation, as they explore different areas of the home. ​

Identifying Spider Nests in Your Home

Spider nests, particularly those of brown recluse spiders, are often hidden in secluded areas. They don't build traditional webs; instead, they create irregular, loosely woven webs in corners, behind furniture, or inside storage boxes. These webs are used for retreat rather than trapping prey. You might also notice egg sacs—small, white, cotton-like balls—which indicate breeding activity.

FAQs About Brown Recluse Spiders

❓ How do I know if it’s a brown recluse?

Brown recluse spiders are light to medium brown and have a distinct violin-shaped mark on their back. They have six eyes (unlike most spiders that have eight), and their legs are uniformly colored without bands.

❓ Are brown recluse spiders common in Missouri?

Yes. Missouri, including St. Louis County, is within the native range of the brown recluse. They thrive in this region’s climate, especially in undisturbed residential structures.

❓ Can brown recluse spiders infest an entire house?

Yes—especially if conditions are right. Clutter, lack of cleaning, or pest prey populations can create a haven for brown recluses. Infestations often go unnoticed due to their nocturnal and shy nature.

❓ Are store-bought sprays effective?

Not usually. Brown recluses are elusive and hide in places that over-the-counter sprays won’t reach. Without professional-grade tools and inspection, treatment may only drive them deeper into your walls.

❓ How fast do they reproduce?

Brown recluse spiders lay several egg sacs, each containing up to 50 spiderlings. A small, undetected population can grow quickly if left untreated.

Taking Action: Protecting Your Home

If you suspect a brown recluse infestation, it's essential to act promptly. Start by decluttering your home, especially in storage areas, to eliminate hiding spots. Seal cracks and gaps in walls, windows, and doors to prevent entry. Regularly vacuum and clean to remove webs and egg sacs. However, due to the potential risks associated with brown recluse bites, professional pest control services are recommended for thorough inspection and treatment.
