Pests that drive problems in Nashville

  • Subterranean termites. UT Extension is direct that termite work is not a do-it-yourself project - its guidance reads, "We do not recommend that homeowners attempt termite control themselves. Seek a professional!" Termites most easily enter where wood is in direct contact with the soil, around doors, wooden steps, porches, and unexcavated portions of a structure. [source]
  • Ticks. Middle Tennessee sits within the expanding range of the invasive Asian longhorned tick, which UT Extension reports is now found in eastern and middle Tennessee counties. Females reproduce without males, giving the species high reproductive potential and short generation times. [source]
  • Mosquitoes. The mosquito problem here is a standing-water problem. UT Extension advises eliminating larval sites around the home twice a week - unclogging gutters and emptying children's pools, pet bowls, flower-pot saucers, old tires, and other containers where water collects. [source]
  • Fire ants. Fire ants turn up in residential areas, schools, playgrounds, and parks across Tennessee, and UT Extension recommends baiting them in the evening during warm months when soil-surface temperatures sit between 70 and 85 degrees F. Urban entomologist Karen Vail warns that anaphylaxis from insect stings can be fatal, so these are a health issue in the lawn, not just a nuisance. [source]
  • Wasps, hornets, and yellowjackets. Many types build paper and mud nests around homes, in the ground, or in shrubs, which is why stinging-insect calls climb every summer as nests mature near doorways, eaves, and play areas. [source]
  • Black widow and brown recluse spiders. UT Extension names these two as the most dangerous spiders in Tennessee. The brown recluse in particular is one where, in UT Extension's words, "quite often a professional pest management company should be used." [source]

When pests peak here

Tick season here is long rather than strictly summer. UT Extension tells Tennessee pet owners to use tick and mosquito prevention products year-round, since ticks can be active even in winter months, and the invasive Asian longhorned tick has been documented active in Tennessee from March through the end of November. Summer is the peak stretch for tick- and mosquito-borne disease risk. Fire ant baiting works best in the evening during warm months, when soil-surface temperatures sit between 70 and 85 degrees Fahrenheit. Termites are harder to pin to a calendar - UT Extension notes an infestation may go undiscovered until the colony swarms, sometimes years after it starts - so year-round vigilance matters more than a single swarm date.

Local factors

  • Humid, warm-season-heavy climate. Nashville's climate normals run from a January high near 49 degrees to a July high near 91 degrees Fahrenheit, with about 50 inches of rain a year spread fairly evenly across the months rather than concentrated in one wet season, and roughly 49 days a year at or above 90 degrees. That steady moisture keeps standing-water mosquitoes and moisture-loving ticks and termites in play for much of the year. [source]
  • Crawl-space and foundation construction. Crawl-space and foundation details drive termite risk. UT Extension notes that poorly ventilated crawl spaces form humid dead-air pockets conducive to termites, powderpost beetles, and carpenter ants, and recommends keeping a 12- to 18-inch bare zone next to the foundation and at least 6 inches of clearance between the soil and the top of the foundation, since mulch piled against the wall can give termites a path around treated soil. [source]
  • Tennessee licensing. In Tennessee, pest control technicians must pass a test and carry a commercial pesticide applicator certification card approved by the Tennessee Department of Agriculture before applying pesticides in a home, and they must work for a licensed operator to charge a fee. Termite work in particular calls for specialized equipment to apply large volumes of insecticide to every possible entry point. [source]
  • Fast growth and new construction. Davidson County and the Nashville area remained Tennessee's fastest-growing in 2025. New subdivisions cut into wooded and formerly agricultural land create the disturbed, brush-bordered landscape that raises tick and termite exposure - fresh grading, new mulch beds against foundations, and lawns backing up to tree lines.

Metro Nashville sits in humid Middle Tennessee, and its pest pressure tracks the region’s warmth and steady rainfall. Termites are the headline structural pest, and UT Extension is unusually direct that treating them is a job for a certified professional rather than a homeowner. Ticks are the headline health concern: Middle Tennessee is within the expanding range of the invasive Asian longhorned tick, and several Tennessee tick species are tied to real diseases. Mosquitoes track standing water around the home, while fire ants, paper wasps, and the black widow and brown recluse round out the list. The EPA calls subterranean termites the most common form of termite in the United States and ties them to billions of dollars in structural damage nationally each year.

If you want it handled, comparing licensed local quotes is the fastest route, and in Tennessee that means a technician certified by the state Department of Agriculture. If you would rather do it yourself, the highest-value work is preventive: remove standing water, keep mulch and wood off the foundation, seal entry points, and use an EPA-registered repellent when tick and mosquito activity is high. Active termite infestations are the exception - UT Extension recommends leaving those to a professional.
