Most ants and spiders are nuisances, but carpenter ants, fire ants, brown recluses, and black widows deserve more attention. Spraying visible ants rarely reaches the colony, so professionals often use baits plus exterior treatment. Spider control focuses on identification, reducing the insects spiders eat, targeted treatment of hiding spots, and sticky monitors.

Ants and spiders are two of the most common reasons Middle Tennessee homeowners call for pest help. Most are nuisances, but a few, like carpenter ants, fire ants, and venomous spiders, deserve more attention.
Common ants in Middle Tennessee
- Odorous house ants. Small dark ants that smell like rotten coconut when crushed. They trail into kitchens, especially after heavy rain.
- Carpenter ants. Large ants that excavate damp or damaged wood to nest. Piles of fine sawdust-like material, called frass, are a sign. They point to a moisture problem worth fixing.
- Pavement ants. Small ants that nest under slabs, sidewalks, and driveways.
- Imported fire ants. Aggressive stinging ants that build mounds in lawns and open areas. They have spread into parts of Tennessee, including some Middle Tennessee counties.
Why spraying ant trails rarely works
Killing the ants you can see doesn't reach the colony or the queens. Repellent sprays can even cause some species to split into multiple colonies. Professionals often use slow-acting baits that workers carry back to the nest, combined with exterior treatments and fixing the conditions that attract ants.
Spiders in Middle Tennessee
Most spiders in and around homes are harmless and actually help by eating other insects. Two venomous spiders are found in Tennessee and are worth knowing:
- Brown recluse. Tan to brown with a darker violin-shaped mark on its back. It hides in undisturbed areas like closets, boxes, attics, and behind furniture. Bites are uncommon, since the spider is not aggressive.
- Black widow. Shiny black with a red hourglass on the underside. It's usually found in sheltered outdoor spots like woodpiles, sheds, meter boxes, and under outdoor furniture.
If you're bitten and develop severe pain, a spreading wound, or symptoms like muscle cramps or trouble breathing, seek medical care.
How spider control works
- Inspection to identify species and find where they're living.
- Reducing their food supply by controlling the insects they eat.
- Targeted treatment of cracks, voids, and harborage areas.
- Web and egg sac removal around eaves, windows, and porches.
- Sticky monitors in closets, basements, and crawlspaces, which are especially useful for brown recluse.
What you can do
- Clean up crumbs and sticky spills, and store sweets in sealed containers.
- Fix leaks and wood rot that attract carpenter ants.
- Reduce clutter and store items in sealed plastic bins rather than cardboard.
- Shake out shoes, gloves, and clothing stored in garages or sheds.
- Wear gloves when moving firewood or stored boxes.
- Keep children and pets away from fire ant mounds.

Frequently asked questions
Are brown recluse spiders found in Middle Tennessee?
Yes. Brown recluse spiders are found in Tennessee and hide in undisturbed spots like closets, boxes, and attics. They're not aggressive, and bites are uncommon. Seek medical care for a painful or worsening bite.
Why do ants come inside after it rains?
Heavy rain can flood nests and send ants looking for higher, drier ground and food, which often leads them into kitchens and bathrooms.
Do carpenter ants damage wood like termites?
Carpenter ants don't eat wood, but they excavate it to nest, usually in wood that's already damp or damaged. Their presence often points to a moisture problem that should be fixed.
