Why Are Scorpions Common in San Antonio?

San Antonio’s warm climate and rocky terrain make it an ideal environment for scorpions. They prefer dry, arid areas but will venture into homes in search of food, water, and shelter. With mild winters, scorpions remain active year-round, though they are most commonly seen in the warmer months.

Common Scorpion Species in San Antonio

1. Striped Bark Scorpion (Centruroides vittatus)

• The most common scorpion in Texas.
• Yellowish-tan with two dark stripes along its back.
• Can climb walls and ceilings, making them more likely to end up inside homes.
• Their sting is painful but rarely dangerous unless you have an allergic reaction.

2. Texas Cave Scorpion (Pseudouroctonus reddelli)

• Found mainly in caves and rocky areas but can sometimes enter homes.
• Dark brown or black in color.
• Less common than the striped bark scorpion but still present in the area.

How to Keep Scorpions Out of Your Home

Scorpions usually enter homes by squeezing through small cracks or climbing in through open windows and doors. Here’s how to keep them out:

• Seal Cracks & Gaps – Use caulk or weather stripping around doors, windows, and utility openings.
• Declutter Indoors & Outdoors – Scorpions love to hide under wood piles, rocks, and debris, so keep your yard clean.
• Use Scorpion-Resistant Screens – Standard window screens may not be enough, so consider finer mesh screens.
• Shake Out Shoes & Clothes – Always check shoes, towels, and bedding before use.
• Reduce Other Pests – Scorpions feed on insects like crickets and roaches, so controlling their food source can help reduce their presence.
