Spider Control
& Removal
Most spiders in Middle Tennessee are nuisances. Two of them are medically significant. Here's how to tell the difference — and why the real solution is eliminating the insect population that's feeding them.
Spiders in Middle Tennessee Homes
Tennessee hosts a range of spider species, and most are harmless — they eat flies, gnats, and other insects and prefer to stay out of your way. The ones you typically see crossing the floor or building webs in corners are common house spiders (Parasteatoda tepidariorum), identifiable by their tangled, cobweb-style webs in upper corners, basement ceilings, and along window frames. Wolf spiders are larger, brown, and ground-dwelling — they hunt rather than web and are often encountered in garages, crawlspaces, and along basement walls. Their size alarms people, but they are not dangerous.
The two species that deserve serious attention are the brown recluse (Loxosceles reclusa) and the black widow (Latrodectus mactans). Both are confirmed in Middle Tennessee and both are medically significant. The brown recluse prefers undisturbed clutter — cardboard boxes, folded clothing, stored items in crawlspaces and attics. Its venom can cause necrotic skin lesions that require medical treatment. The black widow favors low, protected spaces: under decks, around exterior utility boxes, and in crawlspace corners. Its venom is a potent neurotoxin.
Neither species is aggressive, but accidental contact — reaching into a box, shaking out a stored jacket, or working in a crawlspace — is enough to trigger a defensive bite.

Signs You Have a Spider Problem
One or two spiders caught crossing a floor is normal. These signs point to an established population that needs professional attention.
Webs in Corners & Eaves
Multiple active webs in interior corners, along ceiling joists, on eave soffits, or in the garage are a sign of an established house spider population. The webs themselves are the food trap — if the webs are being replenished regularly, spiders are feeding successfully inside your home.
Egg Sacs in Crawlspaces
Spider egg sacs are papery, round or tear-drop-shaped structures attached to webs or surfaces in dark, undisturbed areas. A single brown recluse egg sac can contain 30–50 spiderlings. Finding multiple egg sacs in your crawlspace, attic, or basement storage area means the population is actively reproducing and growing.
Frequent Indoor Sightings
Seeing one spider per week or more indoors — especially in living spaces, bedrooms, or bathrooms — is a reliable indicator of a larger population nearby. Spiders are territorial and solitary; the ones you see represent a fraction of the total population in wall voids, crawlspaces, and stored materials.
High Insect Activity
Spiders go where the food is. If your home has a significant population of flies, gnats, ants, or other small insects, it becomes an attractive hunting ground. An increase in spider activity almost always tracks with an increase in their prey — which means treating the spider problem also means treating the underlying insect problem driving it.
Why Killing Spiders One at a Time Doesn't Work
Consumer spider sprays kill individual spiders on contact, but they do nothing to address the population living in wall voids, crawlspaces, and stored materials — the places you never see. More importantly, they do nothing to reduce the insect population that is sustaining the spiders in the first place. Within weeks, new spiders move in to exploit the same food source.
Professional spider control works on two levels simultaneously. First, we physically de-web the accessible surfaces — eaves, corners, garage ceilings, crawlspace joists — removing existing webs and egg sacs. Then we treat with a residual product that spiders contact as they move across treated surfaces. Finally, and most critically, we treat the insects they are feeding on. Reduce the prey, and the predator population follows. This is why our Quarterly Pest Control plan, which targets the full spectrum of common insects, is the most effective long-term spider management strategy available for Middle Tennessee homes.
How Tall Paul Eliminates Spiders
De-web. Treat the spider. Treat the food source. Repeat quarterly. It's that straightforward.
Thorough Inspection
We inspect interior and exterior for active webs, egg sacs, spider species identification, and the insects they are feeding on. For homes with brown recluse or black widow activity, we document the locations of confirmed sightings and note harborage areas — crawlspaces, attics, cluttered storage, exterior utility boxes — where these species are most commonly found.
De-Webbing Interior & Exterior
We physically remove webs and visible egg sacs from all accessible surfaces — eaves, soffits, garage interiors, basement ceilings, and crawlspace joists. Removing the web structure eliminates the egg sacs, disrupts established territories, and forces spiders to contact treated surfaces as they attempt to rebuild — maximizing the effect of the residual treatment that follows.
Interior & Exterior Residual Treatment
We apply a residual insecticide along baseboards, in corners, across crawlspace and garage floor perimeters, and on the exterior foundation band. Unlike contact sprays, residual treatments continue working for weeks after application. Spiders that move across treated surfaces absorb a lethal dose without needing to be hit directly. We also treat all identified entry points to reduce migration from outdoors.
Insect Reduction — Removing the Food Supply
Sustainable spider control means reducing what feeds them. Our Quarterly Pest Control plan targets the broad spectrum of insects — flies, gnats, ants, earwigs, and more — that sustain spider populations inside Tennessee homes. When the insect population drops, the spider population follows within one to two service cycles. Learn about Quarterly Pest Control →

Frequently Asked Questions
Straight answers to the questions we hear most often about spiders in Middle Tennessee homes.
Brown recluse spiders are tan to light brown with a distinctive violin-shaped marking on the top of the cephalothorax (the front body section). They have six eyes arranged in pairs rather than the typical eight. They prefer undisturbed areas — inside cardboard boxes, between folded items in storage, behind furniture pushed against walls, and in crawlspace clutter. If you are finding them repeatedly in a specific area, that area likely contains an established population. Our inspection includes crawlspace and attic evaluation specifically for recluse harborage. Do not attempt to capture or handle them yourself; call us for a proper assessment.
Wolf spiders are not medically significant. They are large and fast-moving, which makes them alarming to encounter, but their venom is mild and a bite — which only occurs under direct pressure — produces little more than localized irritation in most people. That said, a wolf spider population inside your home signals that the insect prey population supporting them is also significant. They are an indicator species — if you are seeing wolf spiders regularly indoors, we recommend a full inspection to assess what else is living in your crawlspace and basement.
Yes. Crawlspaces are among the most significant spider harborage areas in Tennessee homes — they are dark, undisturbed, humidity-controlled by the soil, and full of structural surfaces that support web-building. Our crawlspace treatment includes de-webbing all accessible joists and piers, treating the perimeter and floor with residual product, and identifying any entry points from the exterior. Crawlspace treatment is included in our standard service for homes with accessible crawlspaces.
For most homes in Middle Tennessee, quarterly service is the right cadence. Spider populations rebuild quickly — they are productive, territorial, and the food supply (insects) replenishes seasonally regardless of past treatments. A single annual treatment will reduce numbers temporarily but will not sustain control year-round. Our Quarterly Pest Control plan provides four treatments timed to seasonal insect and spider activity peaks, plus unlimited service calls between scheduled visits at no additional cost. Most customers on the plan see dramatic improvement within the first two service cycles.
