Chiggers are larval mites that live in tall grass and brush. Control them by mowing low, clearing debris, applying permethrin or bifenthrin to yard edges, and treating bites with anti-itch creams. For severe infestations, professional treatment costs $100–$300.
Key Takeaways
- →Chiggers are larval mites, not insects; they feed on skin cells, causing intense itching.
- →Peak season in Texas is May–September, especially after rain in humid areas.
- →DIY control: mow grass to 2 inches, remove brush, and spray yard perimeter with insecticide.
- →Professional treatments range $100–$450 and often include a 30-day guarantee.
- →Myth: Chiggers do not burrow into skin; they inject enzymes and drop off after feeding.

Who This Is For
This guide is for Texas homeowners, especially those with children or pets who play in grassy or wooded areas. If you've had chigger bites in the past or want to prevent them, you'll find practical steps. It's also for renters managing shared yards and property managers dealing with complaints. We assume you want effective, safe control without wasting money on gimmicks.
The Problem
Chiggers are the larval stage of trombiculid mites, and only the larvae bite. They congregate in tall grass, brush, and shaded, humid ground cover—exactly the kind of habitat found across Texas. When a person brushes against vegetation, chiggers climb onto the skin and migrate to areas where clothing fits tightly (ankles, waist, armpits). They do not burrow; instead, they inject digestive enzymes that liquefy skin cells, creating a feeding tube. The result: intensely itchy welts that can last a week or more. The itch is caused by an allergic reaction to the enzymes, not by the mite itself, which drops off after a few days. In Texas, the peak season runs from late spring through early fall, with activity highest after summer rains. The problem is concentrated in the eastern half of the state (Houston, Beaumont, Dallas) and along the Gulf Coast, where humidity is highest. In arid West Texas, chiggers are less common but can still be found in irrigated lawns or near water sources.
Warning Signs
- •Itchy red welts, often in clusters, around ankles, waist, groin, or armpits—especially after outdoor activity.
- •Bites that appear 1–3 hours after exposure and intensify over 24–48 hours.
- •Seeing tiny red/orange specks (the mites) on skin or clothing after being in grassy areas.
- •Dense, overgrown grass or brush near your home, especially shaded, damp areas.
- •Pets scratching excessively, especially on bellies or between toes, after being in tall grass.
- •Multiple family members or neighbors reporting similar bites after being outside.
- •Presence of wildlife (rodents, deer, birds) that can carry chiggers into your yard.
Risks of Waiting
- ⚠Prolonged itching can lead to secondary skin infections from scratching, especially in children.
- ⚠Untreated infestations can spread as chiggers are brought into the home on clothing or pets.
- ⚠Repeated exposure may increase allergic reaction severity over time.
- ⚠Yard infestations worsen in late summer as chigger populations peak, making control more difficult.

Treatment Options
Perimeter Spray (Professional)
$150–$300A licensed technician applies a liquid insecticide (bifenthrin, cypermethrin, or lambda-cyhalothrin) to the yard perimeter, brush edges, and shaded areas. The treatment creates a barrier that kills chiggers on contact and provides residual protection for up to 30 days.
Granular Insecticide (DIY)
$20–$50 per bag (covers up to 5,000 sq ft)Broadcast granular bifenthrin or permethrin over lawns using a spreader. Water in lightly to activate. Effective for 2–4 weeks. Safer for flowering plants than sprays.
Natural/Organic Treatment (DIY)
$15–$30 per applicationApply sulfur powder (elemental sulfur) to lawns and brush areas—chiggers avoid sulfur. Alternatively, use neem oil sprays. Less effective than synthetic chemicals but safer for pollinators and pets.
The Biology of Chiggers: Why They Bite and How Long They Last
Chiggers are not insects but arachnids—relatives of ticks and spiders. Only the larval stage (six legs) feeds on warm-blooded animals. After hatching from eggs laid in soil, larvae climb onto grass blades and wait for a host. They are attracted to carbon dioxide and body heat. Once on a person, they migrate to areas where clothing fits snugly (ankles, waist, groin, behind knees). Contrary to myth, they do not burrow into skin. Instead, they inject saliva containing digestive enzymes that liquefy skin cells, forming a feeding tube (stylostome). The mite then sucks up the liquefied tissue over several days. The intense itching is an allergic reaction to the enzymes. After feeding, the larva drops off and molts into a nymph, then an adult. Adults live in soil and feed on plant matter, so they don't bite. Understanding this cycle helps in control: targeting larvae before they find a host is key. In Texas, chiggers can complete a generation in 50–70 days, meaning multiple peaks from spring through fall.
Regional Variation in Texas: Where Chiggers Are Worst and Why
Chigger populations vary dramatically across Texas due to climate and habitat. East Texas (Houston, Beaumont, Tyler) is the hot zone—high humidity, frequent rain, and abundant vegetation create ideal conditions. Here, chiggers are a near-certainty from April through October. The Gulf Coast (Corpus Christi, Galveston) also supports heavy populations, especially in coastal prairies and dunes. Central Texas (Austin, San Antonio, Waco) has moderate to high risk, with chiggers concentrated in wooded canyons and along creeks. The Hill Country (Fredericksburg, Kerrville) can be surprisingly bad in shady, moist draws. North Texas (Dallas-Fort Worth) sees chiggers in tallgrass prairies and parks, but activity drops in dry spells. West Texas (El Paso, Lubbock, Midland) is the safest—low humidity and sparse vegetation limit chiggers, but irrigated lawns and parks can still harbor them. In arid regions, chiggers are most common after summer rains. Knowing your local risk helps you tailor prevention and treatment.
The Science Behind Chigger Bite Treatment: What Actually Relieves Itch
Chigger bites are self-limiting: the mite stops feeding after a few days, but the itch can persist for a week or more due to the allergic reaction. Over-the-counter treatments: calamine lotion, hydrocortisone cream, and oral antihistamines (like Benadryl) reduce itching. Cool compresses and oatmeal baths soothe inflammation. Avoid scratching—it can break skin and lead to infection. The myth of using nail polish or bleach to 'suffocate' chiggers is false and harmful; the mite is long gone by the time you feel the bite. For severe reactions, a doctor may prescribe topical steroids or antibiotics for secondary infection. Prevention is far better than treatment: use permethrin-treated clothing, insect repellent with DEET on skin, and shower immediately after exposure. Wash clothes in hot water to kill any lingering mites.

When to Call a Professional
Call a professional if you have a large yard (over half an acre), a persistent infestation that DIY treatments haven't controlled, or if you're unsure about proper insecticide use. Also call if children or pets have severe allergic reactions to bites, or if you need a quick turnaround before an outdoor event. Chigger Control offers inspection terms that vary by provider and a service guarantee—call +1 888 546 7983.
DIY vs Professional
DIY treatments work well for small, isolated problems—like a patch of tall grass near a playset. Granular or spray insecticides from a hardware store can reduce chigger numbers for a few weeks. However, DIY products are often less concentrated and may need reapplication after rain. Professional treatments use commercial-grade chemicals (like bifenthrin) that last longer and are applied with calibrated equipment to ensure even coverage. Pros also know where to target: along fence lines, under shrubs, and in shaded transition zones where chiggers hide. If you have a large property or want season-long control, going pro is worth the $150–$300 investment. For the average Texas lawn, DIY is a good first step, but don't hesitate to call if the itch persists.
Local Context
Texas spans multiple climate zones, so chigger control strategies vary. In Houston and the Gulf Coast, humidity is relentless; treatments may need reapplication every 3–4 weeks during summer. Focus on shaded, moisture-retaining areas like flower beds and along fences. In Dallas/Fort Worth, chiggers are common in parks and greenbelts; treat the transition zones between lawn and wooded areas. In Austin, the limestone hills create microclimates where chiggers thrive in damp creek bottoms. San Antonio's mix of urban and rural landscapes means chiggers can appear in well-watered lawns near wild areas. West Texas residents should still be vigilant after rains, especially in irrigated yards or near the Pecos River. No matter where you are in Texas, the peak months are May through September, with a secondary spike in early fall. Chigger Control serves the entire state and offers inspection terms that vary by provider—call +1 888 546 7983 to schedule.
Prevention Tips
- ✓Mow grass to 2 inches or shorter; chiggers prefer taller cover.
- ✓Clear brush, leaf litter, and tall weeds from around the house and play areas.
- ✓Create a 3-foot barrier of gravel or wood chips between lawn and wooded areas.
- ✓Trim tree branches to let sunlight dry out shaded, humid spots.
- ✓Wear long pants and socks treated with permethrin when in grassy areas; tuck pants into socks.
- ✓Shower immediately after being outside and wash clothes in hot water.
- ✓Treat pets with vet-approved flea/tick repellent; check for chiggers after walks.
💡 Did You Know?
- ★Chiggers inject digestive enzymes that liquefy skin cells—the mite then drinks the liquid, not blood. The intense itch is your body's allergic reaction to those enzymes.
- ★The myth that chiggers burrow into skin and lay eggs is false. They simply feed and drop off after a few days; the red welt is a feeding tube, not a burrow.
- ★In some parts of the world, chiggers can transmit scrub typhus, but in the continental U.S., they are primarily a nuisance pest.
