San Antonio’s outdoor season is here. The days are getting warmer, the evenings are perfect for backyard gatherings, and your patio is calling your name. But as the weather becomes ideal for you, it also becomes ideal for pests.
Spring marks a major surge in pest activity, and your patio, deck, and backyard can quickly become a hotspot for ants, wasps, spiders, scorpions, and cockroaches—all looking for food, shelter, or a place to nest. If you don’t take steps now, you may find yourself sharing your space with unwanted guests before summer even starts.
Here’s how to pest-proof your patio and make the most of your San Antonio outdoor season—without the creepy crawlers.
1. Ants: The Picnic Crashers
Spring and summer are prime time for ant invasions. San Antonio is home to fire ants, carpenter ants, and sugar ants, all of which become more active as the temperature rises. Fire ants are aggressive and deliver painful stings, while carpenter ants can weaken wooden patios and decks.
Ants are drawn to leftover food, sugary spills, and moisture, making patios a perfect feeding ground. If they establish trails or a nest nearby, they’ll keep coming back in larger numbers.
Pro-Tip: Ants follow scent trails. A mix of vinegar and water can help erase trails and keep them from returning.
2. Wasps: Nesting in Hidden Corners
By mid-spring, wasps have already begun building nests under eaves, patio furniture, and outdoor structures. Paper wasps, common in San Antonio, prefer overhangs and railings, while yellow jackets may build nests underground or inside wall voids.
Unlike bees, wasps can sting multiple times and will defend their nests aggressively. A single wasp sighting may not seem like much, but if you don’t catch them early, a small nest can quickly turn into a full-blown colony.
Pro-Tip: Check under your patio furniture, in grill covers, and around outdoor lighting for small nests early in the season. Removing them now prevents a bigger problem later.
3. Spiders: Hiding in the Shadows
Spiders thrive in cluttered spaces, and your patio furniture, storage bins, and firewood piles provide perfect hiding spots. Black widows and brown recluse spiders, two venomous species found in Texas, prefer dark, undisturbed areas, while orb weavers and wolf spiders are more likely to set up around decks and garden spaces.
If your patio has lots of insect activity, spiders will follow. They go where the food is, meaning controlling other pests will naturally reduce spider populations.
Pro-Tip: Keep storage areas tidy, and shake out cushions, shoes, and stored items before using them.
4. Scorpions: The Nighttime Hunters
Scorpions become far more active in the spring, particularly in areas with wood, stone, or dense vegetation—all common around patios and backyards. The striped bark scorpion, the most common species in San Antonio, prefers to hide under patio furniture, in cracks, or near firewood piles.
Scorpions are nocturnal hunters, which means you might not see them until you accidentally reach into their hiding spot. Their sting is painful and can cause swelling, numbness, and in some cases, more serious reactions.
Pro-Tip: Keep wood piles at least 20 feet from your home, and seal gaps under doors and patio structures to block scorpion entry points.
5. Cockroaches: Uninvited Guests at Every Outdoor Gathering
Cockroaches are highly active in warm weather, and patios provide the perfect combination of moisture, shelter, and food scraps. In San Antonio, the American cockroach, smoky brown cockroach, and German cockroach are the biggest problems.
Cockroaches aren’t just unsettling to see—they carry bacteria that contaminate surfaces and trigger allergies and asthma. Their populations explode quickly, so if you see one, there are likely many more nearby.
Pro-Tip: Roaches love dark, damp spaces, so keep patio areas dry, remove standing water, and store pet food indoors.
