When Are Scorpions Most Active in Central Texas?

Answer Guide · Published Sep 8, 2026

Quick answer: In Central Texas, striped bark scorpions are most active from late April through October, peaking in the hot summer months and in the days after heavy rain. They hunt at night and move indoors during drought (seeking water) and as nights cool in fall.

The short version

Scorpion activity in the Buda–Dripping Springs–Wimberley corridor tracks heat and moisture. Warm nights bring them out to hunt; drought and cooling fall nights push them toward the water and shelter your home provides.

Month by month in Central Texas

April–May: Activity ramps up as nights warm. First indoor sightings of the year usually start here.
June–August: Peak season. Hot, dry stretches drive scorpions toward homes for moisture; you'll see the most bathroom and closet sightings now.
September–October: A second push indoors as nights cool and they look for a warm place to overwinter.
November–March: Largely dormant, sheltering in walls, attics and rock — but a warm indoor wall can keep a few active year-round.

Why they head indoors

Two triggers matter most: water (during drought) and temperature (during fall cool-downs). Both are strongest in the Hill Country, where limestone and cedar give scorpions endless daytime harborage right next to houses.

What to do about it

Because activity peaks predictably, the most effective approach is seasonal: seal entry points and treat the perimeter before summer and again heading into fall, and keep the insects scorpions feed on knocked down year-round. A licensed local technician can time treatments to the Central Texas scorpion calendar rather than reacting after they're already inside.

Good questions

Frequently asked

Scorpions are nocturnal — they hunt at night and hide during the day in cool, dark harborage like rock, wood piles, and wall voids. Sightings indoors are most common after dark.

Yes. Heavy rain floods their outdoor harborage and pushes scorpions to higher, drier ground — often your foundation, garage and interior walls — so sightings frequently spike in the day or two after a storm.

Most often in bathrooms, closets, laundry rooms and along baseboards — anywhere cool, dark and near moisture. They can also climb, so they turn up in tubs, sinks and occasionally on walls and ceilings.
