Key Takeaways:
Homeowners are far more likely to detect a spider problem through the physical evidence left behind—such as webs, egg sacs, and fecal spotting—than by spotting the reclusive pests themselves.- The presence of specific signs, like finding perfectly intact shed skins or encountering spiders that do not build webs, can help identify exactly which species has moved indoors.
- The hot, humid climate of the Mid-South creates ideal indoor environments that attract both harmless nuisance spiders and medically dangerous species like the Brown Recluse and Southern Black Widow.
- Effectively resolving a spider infestation requires a comprehensive approach that targets their food source and seals off entry points rather than just clearing away visible cobwebs.
How Do You Know If You Have a Spider Problem?
Spotting a spider lurking in the corner of your room can be unsettling. What’s worse is wondering how many more are hiding just out of sight in your walls, attic, or crawl space. While many common household spiders in the Mid-South are harmless nuisance pests, a growing spider population inside your home is often a symptom of a larger underlying pest problem.
If you are worried that you might have an active spider infestation, the local pest control specialists at [Company] have put together the definitive guide on what signs to look for in your Memphis home.
Top Signs of a Spider Infestation in the Mid-South
Spiders are reclusive creatures that seek out quiet shelter and a steady supply of food. Because they avoid human interaction, you are far more likely to see the evidence they leave behind rather than the arachnids themselves. Keep an eye out for these four signs of spider activity:
- Webs: While some spiders hunt on foot, web-building species like the common house spider and cellar spider leave messy, tangled webs in corners, along window frames, and inside ventilation systems.
- Egg Sacs and Shed Skins: Spiders produce silken, ball-like egg sacs that can harbor hundreds of eggs. Finding these sacs—or finding translucent, shed spider exoskeletons in storage areas—means spiders are actively breeding and growing on your property.
- Fecal Spotting: Heavy infestations leave physical evidence on walls, baseboards, and underneath furniture. Spider droppings look like small, dark, ink-like spots or smears that can ruin paint and fabrics.
- An Influx of other pests: Spiders go where the food is. If your Memphis home currently has an influx of flies, ants, moths, or roaches, spiders will inevitably move indoors to exploit the food source.

What Does It Mean If You See Webs All the Time but Rarely See the Spiders Themselves?
If you see messy webs everywhere but rarely see the spiders, you are likely dealing with common house spiders or cellar spiders tracking high humidity or an influx of flying insects.What If You See Spiders Frequently but Never Any Webs?
What If You See Shed Spider Skins All Over the Place?
Be careful if this is the case. The brown recluse spider, a relatively common spider in the Mid-South with a medically significant bite, is notorious for leaving its perfectly intact exoskeletons behind in undisturbed storage areas. You may find these in quiet, low-traffic areas, though they will occasionally venture out. Closets and old storage boxes are common hiding places.Which Types of Spiders Are Most Likely to Infest Your Memphis Home?
Because Memphis sits right in the heart of the native range for several spiders, an infestation usually points to one of the following common species.| Spider Species | Likelihood | Where to Find | Specific Signs | Danger Level |
|---|---|---|---|---|
| Common House Spider (Parasteatoda tepidariorum) | Extremely High | Corners of rooms, window frames, basements, and closets. They prefer quiet, upper corners. | Messy, tangled cobwebs that seem to appear overnight; small, paper-like brownish egg sacs hanging in the webs. | Harmless Nuisance |
| Cellar Spider (Pholcidae) | High | High-humidity areas like Memphis crawl spaces, damp basements, and under sinks. | Extremely loose, erratic webs in dark corners. When disturbed, these spiders vibrate rapidly in their webs, making them blur. | Harmless Nuisance |
| Wolf Spider (Lycosidae) | Moderate to High (Seasonal) | Ground floors, baseboards, under furniture, and near doorways. They do not spin webs to catch prey. | Zero webs. Instead, you will see large, hairy spiders moving quickly across the floor at night. In late summer, you may spot females carrying a prominent, round egg sac attached to their rear. | Low (Painful bite, but bites are rare and not medically dangerous) |
| Brown Recluse (Loxosceles reclusa) | Moderate | Deep inside undisturbed areas: cardboard boxes, cluttered attics, wall voids, and closets. | Irregular, sticky, whitish webs built hidden away in dark corners or boxes (never out in the open). You may also find their distinct, papery shed skins (exoskeletons) in storage areas. | High (Medically significant necrotic venom) |
| Southern Black Widow (Latrodectus mactans) | Low to Moderate | Out of the way, low-to-the-ground outdoor spots like woodpiles, garages, sheds, and crawl spaces. Rarely infests main living areas. | Incredibly strong, coarse webs that make a distinct “crinkling paper” sound when torn. Webs are usually built very close to the ground or in dark corners of garages/crawl spaces. | High (Medically significant neurotoxic venom) |
Watch for These Dangerous Spiders in the Mid-South Region
Memphis is well within the native range of two medically significant species: the Brown Recluse (identifiable by the dark violin shape on its back) and the Southern Black Widow (identifiable by its glossy black body and red hourglass marking). These species frequently hide inside dark closets, boxes, and crawl spaces, and require professional eradication due to their dangerous bites.Why Are There Spiders in My Memphis Home?
Memphis homeowners face unique pest challenges due to our hot, humid summers and proximity to the Mississippi River. The main attractions that bring spiders inside include:- High Humidity and Moisture: The intense humidity in West Tennessee creates damp microclimates inside crawl spaces, basements, and poorly ventilated attics. Moisture-loving pests thrive here, drawing spiders right in after them.
- Undisturbed Harborage (Clutter): Spiders require dark, quiet places to hide and stalk prey. Piles of cardboard boxes, cluttered closets, unorganized garages, and stacked firewood provide the ideal, undisturbed habitat.
- Easy Access Points: Cracks in your home’s foundation, gaps around doors and windows, and torn window screens act as an open invitation for spiders and their prey to wander inside.
