21 Types of Insects in Texas Every Homeowner and Gardener Should Recognize
October 27, 2026
Texas is home to nearly 30,000 documented insect species, making it one of the most insect-diverse states in the country. Texas A&M’s AgriLife Extension notes that out of the 100,000 or so species of insects in the U.S., Texas is home to approximately 29,000 of them. Understanding the types of insects in Texas matters for anyone who gardens, mows a lawn, or simply wants to know what just flew past the porch light.
This guide walks through 21 groups of insects found across the state, from roaches that slip through kitchen cracks to the biting midges that ruin an evening on the patio. Readers interested in how Texas compares to other insect orders more broadly can check animalofthings’ guide to different types of insects for additional context on classification.
1. Roaches (Blattodea)
Roaches thrive in Texas because the state’s warm, humid climate mirrors the tropical conditions many roach species evolved in. The American cockroach (Periplaneta americana) and German cockroach (Blattella germanica) are the two species homeowners encounter most, and both are drawn to moisture, food debris, and dark cracks around foundations.
According to the National Pest Management Association, cockroaches, including American and German cockroaches, thrive in Texas’ warm environment, and these pests can pose a severe health threat by spreading bacteria including E. coli and salmonella. Not every roach is a household menace, though; some exotic species, like the Madagascar hissing cockroach, are popular in the terrarium trade rather than pest control calls. Readers curious about that side of the hobby can browse animalofthings’ rundown of insects kept as pets.
Pro Tip: Sealing gaps around plumbing, weep holes, and door thresholds does more to keep Texas roaches out than any spray, since most infestations start with a handful of scouts finding an easy entry point.
2. Beetles and weevils (Coleoptera)
Beetles make up the largest insect order in Texas, ranging from the harmless convergent lady beetle (Hippodamia convergens) to the destructive billbugs and grubs covered later in this guide. Most beetles share the same basic body plan: hardened forewings that meet in a straight line down the back, protecting a second pair of flight wings underneath.
Texas Parks and Wildlife describes the ladybird beetle as red with black spots, feeding on aphids and helpful to gardeners, which is why many Texas gardeners actively encourage them rather than treat them as pests. June beetles, in the genus Phyllophaga, are far less welcome; their grub stage chews through turf roots all summer before adults emerge to swarm porch lights. Anyone wanting a deeper dive into the state’s beetle diversity can see animalofthings’ guide to beetles in Texas.
3. Earwigs (Dermaptera)
Earwigs get an outsized reputation for a fairly harmless insect. The European earwig (Forficula auricularia) is the species most often found in Texas gardens and mulch beds, identifiable by the curved pincers at the tip of its abdomen.
Despite the pincers, earwigs rarely bite people and cause no structural damage; they mostly feed on decaying plant matter, other small insects, and occasionally tender seedlings. They favor damp, dark spots, so finding a cluster under a flowerpot or landscape timber is common in Texas yards after rain. Texas A&M’s Field Guide to Common Texas Insects lists Dermaptera among the standard orders homeowners will encounter statewide.
4. Flies (Diptera)
Flies cover an enormous range of forms in Texas, from the common house fly (Musca domestica) buzzing around kitchens to biting horse flies that plague livestock and hikers alike. Diptera is defined by a single pair of functional wings, with the second pair reduced to small balance organs called halteres.
Some Texas flies have evolved to look strikingly like bees and wasps as a defense strategy, which can confuse anyone trying to identify what just landed on a flower. Robber flies and certain hoverflies are the most convincing mimics found statewide. Readers who want help telling these look-alikes apart from actual stinging insects can check animalofthings’ guide to insects that look like bees.
5. Mosquitoes
Mosquitoes are arguably the most disliked insects in Texas, and for good reason beyond the itchy bites. The southern house mosquito (Culex quinquefasciatus) and the invasive Asian tiger mosquito (Aedes albopictus) are two of the most common species statewide, both breeding readily in any standing water left after Texas storms.
Pest control industry data notes that mosquitoes can breed in any stagnant water, so Texans can experience surges in mosquito population after a hurricane or significant rainfall, and mosquitoes can transmit diseases including West Nile virus, Eastern Equine Encephalitis, Zika virus and dengue fever.
Important Note: Mosquito-borne illness risk varies by season and region within Texas. This article provides general identification information and is not a substitute for guidance from a local health department or mosquito control district regarding disease risk in a specific area.
6. True bugs (Hemiptera)
True bugs are distinguished by mouthparts built for piercing and sucking rather than chewing, and Texas hosts a wide variety, from harmless leaf-footed bugs to the medically significant kissing bug. Kissing bugs, also called conenose bugs, are recognizable by the orange or red bands along the edge of their dark bodies.
Local pest identification resources point out that kissing bugs are dark insects with distinctive orange bands, get their name because they tend to bite around the mouth, and can carry Chagas disease, which can lead to heart disease. Several other Hemiptera pests, including chinch bugs, are common enough on Texas lawns to warrant their own sections later in this guide.
7. Aphids (Homoptera)
Aphids are among the smallest insects a Texas gardener will fight, but their numbers make up for their size. These pear-shaped, soft-bodied insects appear in green, yellow, red, or black depending on species and host plant.
Identification guides for Texas insects describe them as measuring about 0.12 inches in length and typically found in various colors including green, yellow, red, or black. Woolly aphids, coated in a white waxy fuzz, are a distinct variant that shows up on pecan and elm trees statewide. For a sense of how much more extreme aphid and insect diversity can get outside Texas, the rundown of insects in the Amazon rainforest offers a striking comparison.
8. Ants, wasps, and bees (Hymenoptera)
Hymenoptera is one of the most successful insect orders in Texas, and it includes some of the state’s most beneficial pollinators alongside its most feared stinging insects. Most species in this order have two pairs of clear, membranous wings and chewing mouthparts, with females often equipped with an egg-laying organ that doubles as a stinger.
Pest control data shows that Texas is home to over 200 species of ants, most of which are relatively harmless, though species like carpenter ants, odorous house ants, crazy ants, and fire ants can pose a significant threat to homes. The red imported fire ant, in particular, has become one of the most recognized lawn pests statewide, delivering a painful sting when its mound is disturbed. The following four sections cover the order’s most notable stinging members in more detail.
9. Termites (Isoptera)
Termites cause more structural damage in Texas than any other insect on this list, and the eastern subterranean termite (Reticulitermes flavipes) is the species most homeowners deal with. Colonies live underground or within damp wood, building mud tubes to travel between soil and a food source without being exposed to open air.
Texas’s mild winters let termite colonies stay active nearly year-round in many regions, unlike in colder northern states. Readers dealing with suspected termite damage may also want to review animalofthings’ broader guide to insects that eat wood, since several other pests produce similar-looking damage.
10. Paper wasps
Paper wasps build the distinctive open, umbrella-shaped nests often found under eaves, porch ceilings, and mailboxes across Texas. The Guinea paper wasp (Polistes exclamans) is one of the most common species statewide, recognizable by its slender body and long, dangling legs during flight.
Paper wasps are generally less aggressive than yellowjackets and mostly sting only when their nest is directly threatened. They also provide a genuine benefit to Texas gardens, since adults hunt caterpillars and other soft-bodied pests to feed their larvae.
11. Yellowjackets
Yellowjackets are far more defensive than paper wasps and account for a large share of stinging insect complaints across Texas. The southern yellowjacket (Vespula squamosa) often nests underground or in wall voids, which means a nest can go unnoticed until someone accidentally disturbs it while mowing or gardening.
National pest data confirms that while paper wasps will only sting if their nest is threatened, species like yellowjackets are far more volatile, and yellowjackets can sting humans repeatedly and trigger an allergic reaction. Anyone dealing with a suspected underground nest should treat it with caution rather than DIY removal, and animalofthings’ guide to poisonous animals in Texas covers several other species worth knowing about before spending time outdoors.
12. Africanized honey bees
Africanized honey bees are a hybrid strain descended from the African subspecies Apis mellifera scutellata, crossed with European honey bee populations already established in the Americas. They look nearly identical to standard honey bees but respond to disturbances far more aggressively, in larger numbers, and for longer periods.
Pest industry sources note that when aggravated, Africanized bees have been known to pursue people for more than a quarter of a mile, which is why professional removal is strongly recommended over DIY methods for any suspected hive. For a closer look at how Africanized bees compare with the state’s gentler native species, see animalofthings’ guide to bees in Texas.
Important Note: Africanized honey bee colonies can pose a genuine safety risk. If a hive is suspected on a property, contacting a licensed pest control professional or beekeeper is safer than attempting removal without training.
13. Chinch bugs
Chinch bugs are one of the most damaging lawn pests in Texas, particularly on St. Augustine grass. The southern chinch bug (Blissus insularis) is small, dark, and easy to overlook until the damage it causes becomes obvious.
According to turf pest identification resources, chinch bugs suck the sap from grass, leading to yellow spots that turn brown and die, and they mainly affect Zoysia, Bermuda, and St. Augustine grass during hot and dry summer months. Confirming a chinch bug problem before treating it saves time and money, since drought stress often looks similar at first glance.
- Look for irregular yellow-to-brown patches that expand outward, often starting near sidewalks or driveways where the grass sits hottest.
- Part the grass at the edge of a damaged patch and check for small, fast-moving insects near the thatch layer.
- Rule out drought stress by watering the area; chinch bug damage will not green back up the way drought-stressed grass does.
14. Grubs
Grubs are the larval stage of several beetle species, most commonly June beetles in the genus Phyllophaga. They spend most of their lives underground, feeding on grass roots before pupating into adult beetles.
Lawn pest identification guides describe grubs as C-shaped, white larvae that feed on grass roots, causing brown spots and grass that easily lifts away from the soil. That lifting test is one of the fastest ways to confirm a grub infestation without digging up half the yard.
15. Tropical sod webworms
Tropical sod webworms are the larval stage of a small tan moth that becomes active at dusk across warm-season Texas lawns. The caterpillars themselves are tan to green with dark spots and feed at night, chewing notches out of grass blades close to the surface.
Damage often appears as ragged, unevenly cropped patches rather than the browning caused by chinch bugs or grubs. Because the adult stage is a moth, readers interested in the broader moth population across the state can browse animalofthings’ guide to moths in Texas for more identification help.
16. Fall armyworms
Fall armyworms are among the fastest-moving lawn pests in Texas, capable of stripping a yard down to bare stems in just a few days when populations peak. The caterpillar, the larval stage of Spodoptera frugiperda, is easy to identify by the inverted Y-shaped marking on its head.
Landscape pest resources note that fall armyworms are cylindrical with a light brown to dark black color and characteristic light stripes along their bodies, measuring 1.5 to 2 inches long and appearing at night or in lower temperatures. Because the adult stage is a moth rather than a butterfly, it is worth noting how the two groups differ; animalofthings’ guide to butterflies in Texas breaks down that distinction in more detail.
17. Mole crickets
Mole crickets are unmistakable once seen up close, with shovel-like front legs built for tunneling rather than jumping. They spend most of their time underground, surfacing mainly at night to feed on grass roots and shoots.
Turf pest guides recommend a simple detection method: add liquid dish soap like Dawn to two gallons of water and pour on a patch of lawn, and the sudsy water will force mole crickets to the surface within a few minutes. This soap flush test works well because it irritates the crickets without requiring any digging.
Pro Tip: Run the soap flush test in the evening when mole crickets are naturally more active near the surface, and check a few different spots in the lawn rather than a single patch.
18. Greenbugs
Greenbugs are a type of aphid that specifically targets grasses and cereal crops, distinguishing them from the broader aphid category covered earlier. They are tiny, bright green, and oval-shaped, usually clustering on the underside of grass blades where they are easy to miss.
Turf identification resources describe greenbugs as widespread lawn pests that are very small, bright green, and oval-shaped, with toxic saliva that destroys chlorophyll in leaves and grass blades, turning them red or rusty brown. That reddish discoloration is often the first visible clue of a greenbug problem, since the insects themselves are so small.
19. Cutworms
Cutworms differ from armyworms and sod webworms in where they cause damage: instead of chewing grass blades, they cut through stems right at the soil line. The larval stage of moths like the black cutworm (Agrotis ipsilon), these caterpillars curl into a tight C-shape when disturbed.
Landscape pest guides note that cutworms cause damage at the base of the plant by cutting stems near the soil line, making them particularly destructive to newly seeded or recently sodded lawns. That makes timing especially important for anyone establishing new turf, since young grass has little root reserve to recover from an infestation.
20. Billbugs
Billbugs are small weevils that damage Texas turf at both the adult and larval stage, making them trickier to control than pests limited to one life stage. The hunting billbug is the species most frequently identified in Texas lawn damage reports, and its larvae resemble white grubs but lack legs entirely.
Texas A&M’s turfgrass IPM program lists the hunting billbug among the primary beetle larvae affecting Texas lawns, alongside grubs and invasive Japanese beetles. The table below summarizes how the eight lawn pests covered in this guide compare at a glance.
| Lawn Pest | Peak Season | Primary Damage Sign |
|---|---|---|
| Chinch Bugs | Hot, dry summer | Yellow patches turning brown |
| Grubs | Summer larvae, spring/fall adults | Grass lifts easily from soil |
| Tropical Sod Webworms | Warm months, active at dusk | Ragged, notched grass blades |
| Fall Armyworms | Late summer into fall | Rapid stripping of grass blades |
| Mole Crickets | Spring eggs, summer activity | Raised tunnels, spongy turf |
| Greenbugs | Warm weather | Reddish-brown discoloration |
| Cutworms | Spring through fall | Stems cut at soil line |
| Billbugs | Spring through summer | Stems hollowed, blades pull loose |
21. Gnats (biting midges, buffalo gnats, fungus gnats, gall gnats, eye gnats)
Gnats cover several unrelated small fly groups in Texas, each with its own habits and nuisance level. Biting midges, sometimes called no-see-ums, are nearly invisible but deliver a disproportionately sharp bite, especially near standing water at dusk.
Buffalo gnats, also known as black flies, target livestock and people alike with painful bites during their brief spring emergence. Fungus gnats are far less aggressive, staying close to overwatered houseplants where their larvae feed on fungus and decaying organic matter in the soil.
Gall gnats lay eggs that trigger abnormal plant growths called galls, while eye gnats are drawn to moisture around the eyes and can be a persistent nuisance during outdoor work in warmer months.
- Biting midges: Nearly microscopic, painful bites, most active at dawn and dusk near water
- Buffalo gnats: Swarm livestock and people in spring, bite aggressively
- Fungus gnats: Harmless to people, breed in overly moist potting soil
- Gall gnats: Larvae cause plant galls rather than biting people
- Eye gnats: Attracted to moisture around eyes, nuisance rather than health risk in most cases
Understanding these 21 types of insects in Texas gives homeowners and gardeners a much clearer starting point for deciding what actually needs treatment versus what is simply part of the state’s ordinary insect life.
Many of the beneficial species covered here, along with the pests, also make up an important food source for Texas wildlife, including the songbirds and shorebirds featured in animalofthings’ guide to water birds in Texas and the reptiles covered in the guide to lizards in Texas.
Between the lawn pests, the stinging insects, and the household invaders, knowing which category an insect belongs to is usually the fastest way to figure out the right response.
