Brown recluse spiders in Texas
Yes — brown recluse spiders are recorded in Texas. The GBIF biodiversity database holds 1,203 verified brown recluse spider records from the state — one of the highest counts in the country. Sightings concentrate in April, May, July, August. Onset: often painless at first. Duration: most heal in weeks; a true necrotic lesion can take months.

Brown recluse spider bites in Texas: what the mark looks like
Genuine brown recluse bites are far rarer than the diagnosis. The spider is uniformly tan with a darker violin-shaped mark behind the eyes and lives in a limited geographic range — roughly Kansas to Texas and east to Georgia. Outside that range a "recluse bite" is almost always something else.
Locally, the species most often confused with it are black widow spider bite, chigger bite, yellow sac spider bite — all of which are also recorded in Texas.
Seek medical care if
- a wound that darkens, blisters or breaks down over days
- fever, chills or widespread rash
- rapidly spreading redness and pain — more often a bacterial infection than a spider
What else it could be in Texas
These are recorded in Texas too and are the ones most often confused with it here. The differences below are the ones that actually separate them.
| Brown recluse spider bite | Black widow spider bite | Wolf spider bite | Yellow sac spider bite | |
|---|---|---|---|---|
| Pattern | single site | single site | single site | single, sometimes two nearby |
| Where on body | torso under clothing, upper arms, thighs — often where clothing was put on with the spider inside | hands, forearms, legs — usually where a hand reached into a dark space | hands, feet, lower legs | neck, arms, torso — often bites received in bed |
| Appears | often painless at first | a sharp pinprick, then pain building over 30 to 60 minutes | immediate sharp pain | stinging pain at the time of the bite |
| Records here | 1,203 | 1,867 | 652 | 111 |
Brown recluse spider season in Texas specifically
Records in Texas concentrate in April, May, July, August, which is what local sighting data shows rather than a national average — seasonality shifts substantially with latitude. The general bite season in Texas runs February to December.
Because undisturbed storage — boxes, wardrobes, behind furniture — in the south-central states, exposure in Texas tends to be concentrated in specific places rather than spread evenly — which is why a bite history ("where were you in the 24 hours before?") narrows the answer faster than the appearance of the mark.

Counts are observations submitted to GBIF, not bites. They tell you when the animal is out and being noticed in Texas; they do not tell you how many people were bitten. The thinnest month with any record at all is January (32).
How Texas compares
Across the 32 states with any brown recluse spider records, Texas ranks 1st with 1,203. Directly below is Missouri (1,130).
Inside Texas itself the picture is different again: of the 22 biting species we track with records here, this one is 7th and accounts for 2% of the 70,626 records logged in the state. A species can be common nationally and marginal in one state, or the reverse — which is the whole reason this page exists separately from the national guide.
Care
- wash, cold pack, elevate the limb
- have a changing lesion assessed rather than treated at home
- do not apply heat, and do not let anyone cut the lesion out early
Avoiding brown recluse spiders in Texas
- shake out clothing and bedding stored in the garage or loft
- gloves when handling boxes
- reduce cardboard clutter
