This section breaks down the top insects by category. You’ll learn about their habits, where they live, and what to do if they become a problem.

Stinging Insects: Wasps, Bees, And Hornets

Stinging insects are a big concern for many Tennesseans. They build nests near homes and can be aggressive when threatened.

Paper Wasps: These build open, umbrella-shaped nests under eaves and porch ceilings. They are brown with yellow markings and can sting repeatedly.
Yellow Jackets: These are more aggressive and often nest in the ground or inside wall voids. They are bright yellow and black, and they scavenge for food at picnics.
Honey Bees: While beneficial for pollination, they can swarm near homes. They are fuzzy and golden-brown, and they usually only sting when provoked.
Cicada Killers: These large wasps look scary but are not aggressive. They dig burrows in sandy soil and prey on cicadas.

To avoid stings, check your property for nests in spring. Seal cracks in siding and foundations. If you find a nest near a door or play area, call a professional.

Ants: Common Household Invaders

Ants are among the most persistent pests in Tennessee. They enter homes looking for food and water, especially during dry spells.

Carpenter Ants: These large black ants damage wood by tunneling through it. They prefer damp, rotting wood but can also infest sound wood.
Fire Ants: Red imported fire ants build large mounds in sunny areas. Their sting is painful and can cause allergic reactions.
Odorous House Ants: Small brown ants that smell like rotten coconut when crushed. They follow trails along countertops and baseboards.
Pavement Ants: These nest under sidewalks and driveways. They enter homes through cracks in the foundation.

Keep ants out by wiping up crumbs, storing food in sealed containers, and fixing leaky pipes. Use bait stations to target the colony, not just the workers you see.

Mosquitoes: The Summer Nuisance

Mosquitoes thrive in Tennessee’s humid summers. They breed in standing water and can carry diseases like West Nile virus.

You’ll notice them most at dawn and dusk. They are small, flying insects with a high-pitched whine. Females bite to get blood for their eggs.

Eliminate standing water in bird baths, gutters, and flower pots.
Use EPA-approved repellents with DEET or picaridin.
Install screens on windows and doors.
Consider using mosquito dunks in ponds or rain barrels.

Cockroaches: Resilient Pests

Cockroaches are hardy insects that can survive in many conditions. In Tennessee, you’ll find a few common species.

German Cockroach: Small, light brown with two dark stripes. They infest kitchens and bathrooms, hiding in cracks and behind appliances.
American Cockroach: Large, reddish-brown, and can fly. They prefer warm, damp areas like basements and sewers.
Oriental Cockroach: Dark, almost black, and slow-moving. They live in cool, damp places like under sinks and in crawl spaces.

To control cockroaches, keep your home clean and dry. Seal gaps around pipes and cabinets. Use gel baits and boric acid powder in areas where they hide.

Beetles: Diverse And Numerous

Beetles are the largest group of insects, and Tennessee has many species. Some are beneficial, while others damage plants or stored food.

Japanese Beetles: Metallic green and copper, they skeletonize leaves on roses, fruit trees, and shrubs.
Ladybugs (Lady Beetles): Beneficial insects that eat aphids and other garden pests. They are red with black spots.
Carpet Beetles: Small, oval beetles that feed on natural fibers like wool, silk, and feathers. They can damage carpets and clothing.
Ground Beetles: Fast-moving, dark beetles that live under rocks and mulch. They prey on other insects and are harmless to people.

For garden beetles, hand-pick them or use neem oil. For carpet beetles, vacuum regularly and wash infested fabrics in hot water.

Flies: More Than A Nuisance

Flies are common in Tennessee, especially during warmer months. They breed in decaying organic matter and can spread diseases.

House Flies: Gray with four dark stripes on the thorax. They feed on garbage and feces, contaminating food.
Fruit Flies: Tiny, red-eyed flies that breed on overripe fruit and fermenting liquids.
Drain Flies: Small, fuzzy flies that breed in drains, sewers, and moist areas.
Horse Flies: Large, painful biters that attack livestock and people near water or wooded areas.

To reduce flies, keep trash cans sealed, clean up pet waste, and fix leaky drains. Use fly traps or sticky strips in problem areas.

Crickets And Grasshoppers

These hopping insects are common in fields and gardens. They can become a nuisance when they enter homes.

House Crickets: Light brown with three dark bands on the head. They are attracted to lights and can chirp loudly indoors.
Field Crickets: Dark brown or black, found in grassy areas. They often enter homes in fall seeking warmth.
Grasshoppers: Green or brown with large hind legs. They feed on leaves and can damage crops and gardens.

Seal cracks around doors and windows. Reduce outdoor lighting that attracts them. Use diatomaceous earth or insecticidal soap for garden infestations.

Termites: Silent Destroyers

Termites cause significant damage to homes in Tennessee. They feed on wood and can go unnoticed for years.

Subterranean Termites: The most common type in Tennessee. They live in underground colonies and build mud tubes to reach wood.
Drywood Termites: Less common, they infest dry wood without soil contact. They leave small piles of fecal pellets.
Dampwood Termites: Found in moist, decaying wood. They are larger and less likely to infest sound wood.

Signs of termites include mud tubes, hollow-sounding wood, and discarded wings. If you suspect termites, get a professional inspection immediately. Prevention includes reducing moisture around the foundation and removing wood debris.

Spiders: Beneficial But Feared

Spiders are not insects, but they are often grouped with them. Tennessee has many spider species, most of which are harmless and helpful.

Brown Recluse: Light brown with a violin-shaped mark on the head. They hide in dark, undisturbed areas and their bite can cause tissue damage.
Black Widow: Shiny black with a red hourglass on the underside. They build messy webs in low, dark places.
Wolf Spiders: Large, hairy, and fast. They hunt on the ground and are not dangerous to humans.
Orb Weavers: Build large, circular webs in gardens. They are colorful and harmless.

To reduce spiders, declutter basements and garages. Seal cracks and use sticky traps. Most spiders are beneficial and control other pests, so consider leaving them alone if they are not in living areas.

Stink Bugs And Shield Bugs

Brown marmorated stink bugs are an invasive species that has become common in Tennessee. They enter homes in large numbers during fall.

They are shield-shaped, brown with lighter bands on antennae. When disturbed, they release a foul odor. They do not bite or damage structures, but they are a major nuisance.

Seal cracks around windows, doors, and siding.
Use a vacuum to remove them indoors, but empty the bag quickly.
Do not crush them, as the smell lingers.

Moths And Butterflies

While butterflies are welcome in gardens, some moths can be pests. Clothes moths and pantry moths are the main concerns.

Clothes Moths: Small, golden moths that lay eggs on natural fibers. Larvae feed on wool, fur, and feathers.
Indian Meal Moths: Common pantry pests. Larvae infest grains, cereals, and dried fruit.
Gypsy Moths: Invasive species that defoliate trees. Their caterpillars are hairy and can cause skin irritation.

For clothes moths, store woolens in airtight containers and use cedar or lavender. For pantry moths, inspect food packages and discard infested items. Clean shelves thoroughly.

Earwigs And Silverfish

These primitive insects are common in damp areas of homes. They are more of a nuisance than a threat.

Earwigs: Dark brown with pincers on the rear. They hide in moist soil and under mulch. They can enter homes through cracks.
Silverfish: Silvery, fish-shaped insects that move quickly. They feed on paper, glue, and starchy materials.

Reduce humidity with dehumidifiers. Seal cracks and remove leaf litter near the foundation. Use sticky traps to monitor and control them.

Centipedes And Millipedes

These many-legged creatures are often found in basements and crawl spaces. They prefer moist environments.

House Centipedes: Long, pale yellow with many legs. They are fast and prey on other insects. Their bite is mild but can be startling.
Millipedes: Dark, cylindrical, and slow. They feed on decaying organic matter and can become numerous after rain.

To control them, reduce moisture and remove debris around the foundation. Seal entry points and use a dehumidifier indoors.

Seasonal Patterns And Prevention Tips

Insect activity in Tennessee follows a seasonal pattern. Knowing when to expect certain pests helps you prepare.

Spring: Ants and termites swarm. Stinging insects build nests. Start sealing cracks and applying barrier treatments.
Summer: Mosquitoes, flies, and beetles peak. Use repellents and eliminate standing water.
Fall: Stink bugs and crickets seek shelter indoors. Seal gaps and use weather stripping.
Winter: Cockroaches and silverfish remain active indoors. Maintain cleanliness and reduce humidity.

General prevention includes keeping your home clean, storing food properly, and maintaining your yard. Trim vegetation away from the house and remove piles of wood or leaves.

When To Call A Professional

Some infestations require professional help. If you have a large termite colony, a wasp nest near a high-traffic area, or a persistent cockroach problem, call an exterminator.

Professionals have access to stronger treatments and can identify hidden infestations. They can also provide ongoing prevention plans.

For minor issues, DIY methods often work. But if you see signs of structural damage or repeated infestations, it’s time to call for help.
