Texas Brown Tarantulas — Complete Guide

About the Texas Brown Tarantula

The Texas brown tarantula (Aphonopelma hentzi) is the most famous spider in Texas — the big, slow, furry tarantula crossing rural roads on warm evenings. It lives in burrows across most of the state, from the Hill Country and North Texas prairies to the South Texas brush and the Panhandle, and it is one of the most harmless large animals you will ever meet. Females can live over 20 years in the same burrow; males live fast, wander far, and die young — which explains nearly every tarantula encounter Texans have. For spiders that do warrant caution, see our Texas spider guide.

Identifying a Texas Brown Tarantula

No other Texas spider matches it: a heavy, densely hairy body 1.5 to 2 inches long with a leg span of 4 to 6 inches, dark chocolate-brown to nearly black legs, and a lighter tan-to-copper carapace and abdomen. They move deliberately — a tarantula walks, it does not dart — and when threatened they rear up and may flick urticating hairs rather than bite.

Why They Wander — Mating Season

Tarantula "season" in Texas runs from late spring through fall, peaking in the warm months and surging after rains. That is when mature males — having spent years in a burrow — leave for good and walk, sometimes hundreds of feet a night, searching for females. The tarantula on your driveway, patio, or garage floor at dusk in July is almost always one of these wandering males in Central, North, or West Texas. They are not moving in; they are passing through on a one-way trip, and the sightings stop when the season ends.

Are They Dangerous?

No. Texas brown tarantulas are famously docile and must be seriously provoked to bite — the bite itself is milder than a bee sting for most people, with brief localized pain. The more common defense is urticating hairs: barbed hairs kicked from the abdomen that irritate skin, and especially eyes and airways. If you handle one (better not to), wash your hands afterward and keep them from your face. Dogs that mouth tarantulas can get a snout full of hairs and a painful bite — keep pets from investigating.

What to Do About a Tarantula

Usually, nothing. They eat crickets, roaches, beetles, grasshoppers, and even small mice — a tarantula in the yard is free pest control, and it will move on. If one needs to be relocated from a garage or porch: place a large container over it, slide stiff cardboard underneath, and carry it to a sheltered spot away from the house. Do not try to pick it up — tarantulas are fragile, and a short fall can be fatal to them.

Do You Need Pest Control for Tarantulas?

Almost never — and we'll say that plainly: there is no tarantula "infestation." They do not nest indoors, breed indoors, or damage anything. If tarantulas wandering into the garage bothers you during mating season, the fixes are door sweeps, sealed thresholds, and turning off porch lights that attract the insects they hunt. A licensed pest control company can help with that exclusion work if needed — browse licensed pest control companies below — but any treatment aimed at tarantulas themselves is unnecessary, and killing these slow-growing, decades-lived native spiders is a loss, not a service.
