Springtime Pest Resurgence in Texas: What to Watch For

As spring rolls into Texas, it brings more than just bluebonnets and barbecue weather. Warmer temperatures, seasonal rains, and rapid plant growth create the perfect storm for increased pest activity across the state. From suburban backyards to rural homesteads, homeowners everywhere begin to notice unwelcome guests making a comeback.

Let’s take a look at why springtime pest problems are especially common in Texas—and what you can do to protect your home.

Why Spring Triggers Increased Pest Activity in Texas

Texas weather in spring is a magnet for pests. As temperatures climb and rains roll in, the landscape becomes lush and full of life. Unfortunately, pests thrive under the same conditions.

• Warmth wakes up dormant insects and speeds up breeding cycles.
• Rain creates standing water, a prime habitat for mosquitoes.
• Vegetation growth offers food and shelter for a wide variety of critters.

Add to that Texas’s diverse ecosystems—from Gulf Coast humidity to Hill Country brush—and you’ve got a whole state ready for a pest explosion.

Common Spring Pests in Texas

Here are the usual suspects you’re most likely to encounter this time of year, and the signs to watch for:

Termites

Spring is swarming season for termites, especially the Eastern subterranean species and Formosan termites—both found throughout Texas. These winged swarmers are reproductive termites looking to start new colonies, often near wood structures.

Watch for:

• Swarms of winged insects near light sources or windows.
• Discarded wings on windowsills or entryways.
• Mud tubes on exterior walls or foundations.
• Hollow-sounding wood or bubbling paint indoors.

Why it matters: Termites can cause significant structural damage before you even notice them. Early detection is key.

Mosquitoes

Thanks to frequent spring showers, standing water becomes abundant—and that’s all mosquitoes need to start breeding. Female mosquitoes can lay hundreds of eggs in just a bottlecap’s worth of water.

Watch for:

• Increased mosquito activity at dusk and dawn.
• Standing water in clogged gutters, birdbaths, flowerpots, or kiddie pools.
• Itchy bites around ankles or exposed skin.

Why it matters: Besides being a nuisance, mosquitoes in Texas can transmit West Nile virus, Zika, and other diseases.

Ants

Ants become highly active in the spring as they search for food and expand their colonies. Two of the biggest offenders in Texas are:

• Fire ants, which create large mound nests and deliver painful stings.
• Carpenter ants, which hollow out wood to create nesting galleries—potentially damaging your home.

Watch for:

• Mounds of loose soil in yards or around sidewalks.
• Trails of ants indoors near kitchens, pantries, or pet food.
• Hollowed-out or moist wood with rustling sounds inside walls (carpenter ants).

Why it matters: Fire ants can swarm quickly and sting pets, children, and livestock. Carpenter ants, while not as destructive as termites, can still weaken wood over time.

Rodents

Rats and mice become increasingly active in spring, particularly after the lean winter months. They seek food, warmth, and nesting areas—often inside attics, garages, or pantries.

Watch for:

• Droppings around baseboards, cabinets, or food storage areas.
• Chewed wires, insulation, or food packaging.
• Scratching noises in walls or ceilings at night.

Why it matters: Rodents can contaminate food, chew through wiring (creating fire hazards), and carry diseases like leptospirosis and hantavirus.

Cockroaches

Warmer weather triggers a boom in roach activity, especially in urban areas like Houston, Austin, and Dallas. Common indoor invaders include the German cockroach (small, fast, and a prolific breeder) and the American cockroach (larger, often found in sewers or basements).

Watch for:

• Roach droppings (tiny, pepper-like specs).
• Unpleasant musty odor.
• Live roaches, especially at night.

Why it matters: Roaches can trigger asthma and allergies, especially in children, and spread bacteria and pathogens.

Prevention & Control Tips

The best defense is a proactive approach. Here’s how to reduce your risk of a springtime infestation:

Yard Maintenance

• Eliminate standing water: Empty birdbaths, buckets, and plant saucers. Clean gutters and improve drainage around your yard.
• Mow regularly and trim back overgrown shrubs, especially those near your home’s foundation.
• Remove debris: Firewood piles, leaf litter, and compost bins can be nesting grounds for rodents, ants, and roaches. Store firewood at least 20 feet from the house and elevate it off the ground.
• Treat lawn and beds: Use ant bait stations, fire ant granules, or mosquito dunks where needed (especially after heavy rains).

Seal Entry Points

• Inspect your home’s foundation, siding, eaves, and roofline for cracks or holes.
• Use silicone caulk or expanding foam to seal small gaps; install mesh screens or covers on vents and chimneys.
• Replace worn door sweeps and weather stripping to keep crawling insects and rodents out.
• Install window screens and repair any tears.

Early Intervention

• Schedule a professional pest inspection each spring. Pros can identify hidden issues like termite damage or rodent activity before it gets serious.
• Set traps or bait stations as a precaution, especially in areas where you've seen past activity.
• Talk to a local pest control company about a seasonal treatment plan tailored to Texas pests and weather conditions.

Don’t Let Pests Take Over This Spring

Spring in Texas should be a time for enjoying the outdoors—not battling bugs and rodents inside your home. Taking early, proactive steps now will save you time, stress, and money later in the season.

From the Gulf Coast to the Hill Country, keeping your home protected starts with knowing what to watch for and acting fast when you see signs of trouble.
