Cockroaches are some of the most unwelcome houseguests in Texas—and unfortunately, they’re also among the most common. If you’ve spotted one scurrying across the floor (especially during the day), it’s likely there are more hiding out of sight.

But before you can get rid of them, it’s important to understand what attracts roaches to your home in the first place. At Varmint Masters, we’ve spent over a decade helping San Antonio and Hill Country homeowners keep their homes roach-free. Here’s what you need to know—and what you can do to keep these pests out for good.

Why Roaches Love Texas Homes

Warm weather and humidity make Texas the perfect environment for cockroaches to thrive—especially in cities like San Antonio, where urban and suburban homes offer easy access to food, water, and shelter. Once they get inside, roaches reproduce quickly, hide well, and are notoriously hard to eliminate without professional help.

What Attracts Roaches?

Knowing what draws cockroaches indoors is the first step to preventing an infestation. Here are the most common reasons roaches might target your home:

1. Food Left Out or Improperly Stored

Roaches are scavengers. Even a few crumbs on the counter or an unsealed bag of chips in the pantry can attract them. Open trash cans, dirty dishes, and pet food bowls are all common culprits.

What to do:

• Store food in sealed containers

• Wipe down counters and tables daily

• Take out the trash regularly

• Don’t leave pet food out overnight

2. Moisture and Water Leaks

Roaches need moisture to survive. They’re often found near sinks, bathtubs, leaky pipes, or in damp basements and crawlspaces.

What to do:

• Fix leaks and dripping faucets promptly

• Run a dehumidifier in damp areas

• Check under sinks for standing water

3. Clutter and Cardboard

Roaches love dark, undisturbed areas where they can hide and breed. Cardboard boxes, paper piles, and cluttered storage spaces are ideal roach real estate.

What to do:

• Declutter garages, attics, and storage closets

• Replace cardboard storage boxes with plastic bins

• Keep closets and cabinets tidy

4. Cracks and Gaps in Your Home’s Exterior

Roaches can squeeze into your home through surprisingly small openings. Common entry points include:

• Gaps under doors

• Cracks in the foundation

• Vents and utility line openings

What to do:

• Seal cracks around windows, doors, and baseboards

• Use weatherstripping and door sweeps

• Install mesh screens over vents

5. Easy Indoor Shelter

When temperatures soar in the summer or drop during colder months, roaches seek shelter indoors. Dark, warm, and humid spaces—like under appliances or inside wall voids—are ideal hiding spots.

What to do:

• Move appliances and clean behind/under them

• Avoid leaving piles of laundry on the floor

• Regularly inspect dark corners and behind furniture

How to Prevent a Roach Infestation

While keeping your home clean and sealed can go a long way, roaches are resilient—and sometimes even the cleanest homes can attract them. That’s why routine pest control is so important in areas like San Antonio and the Hill Country.

When to Call a Professional
