Why Are There So Many Spiders Around My House During Late Summer? A Central Texas Homeowner's Guide

August 24, 2026

While most spiders found in Central Texas are harmless, they can still be an unwelcome sight inside your home. More importantly, an increase in spiders often points to a larger pest problem. Spiders stay where their food is, and if you're seeing more spiders, there is a good chance other insects have already made themselves at home.

At GGA Pest Management, we help homeowners throughout Waco, Temple, Killeen, and across Central Texas identify the source of spider activity and provide year-round pest protection to help keep both spiders and the insects they feed on under control.

Why Are Spiders More Active During Late Summer?

If it seems like spiders suddenly appeared overnight, there is a reason.

By late summer, insect populations have been building for months. August and September bring continued heat, humidity, and plenty of insect activity throughout Central Texas. As the number of insects increases, spider activity increases as well because spiders follow their food source.

Late summer is also when many spiders become more visible as they build larger webs, search for mates, and move into garages, sheds, patios, and sometimes inside homes.

Common Spiders Found in Waco, Temple, and Killeen

Central Texas is home to many different spider species. Fortunately, most are beneficial because they help reduce insect populations around your property.

Some of the most common spiders homeowners encounter include:

• Common house spider
• Wolf spider

• Orb weaver
• Jumping spider

Texas is also home to spiders that should be taken seriously, including:

• Black widow
• Brown recluse

Although encounters with venomous spiders are relatively uncommon, homeowners should avoid handling any spider they cannot confidently identify.

Why Am I Seeing Spiders Inside My House?

Spiders are usually inside your home for one simple reason.

They are following their food.

Unlike ants or cockroaches, spiders are not searching for crumbs or trash. They are hunting insects. If your home has flies, ants, mosquitoes, moths, crickets, or other small bugs, spiders see your home as the perfect place to stay.

Spider activity is often a sign that another pest issue needs to be addressed first. If you are seeing spiders on a regular basis, it may be time to have your home professionally inspected.

Signs You May Have a Spider Problem

Finding one spider from time to time is completely normal.

However, if you are noticing these signs, it may be time to schedule a professional pest inspection.

• Spider webs appearing every few days
• Multiple spiders inside your home each week
• Egg sacs attached to webs or hidden corners
• Spiders in garages, attics, sheds, or crawl spaces
• Increased spider activity around windows, doors, or outdoor lighting

If you are constantly removing webs only to have them return a few days later, there is likely an underlying insect population attracting spiders to your property.

How to Help Prevent Spiders Around Your Home

There are several simple steps homeowners can take to make their property less attractive to spiders.

• Reduce the insects spiders feed on: The fewer insects around your home, the fewer spiders you are likely to see. Keeping ants, flies, mosquitoes, crickets, and other common pests under control is one of the best ways to reduce spider activity.
• Remove webs regularly: Knocking down webs around your home's exterior discourages spiders from returning to the same locations and makes your property less inviting.
• Trim landscaping: Bushes, shrubs, and tree branches that touch your home create easy pathways for spiders and many other pests.
• Reduce outdoor lighting: Bright exterior lights attract flying insects after dark. More insects mean more food for spiders. Switch to warm colored outdoor LED bulbs. Warm yellow lights generally attract fewer flying insects than cool white or bright blue-toned lights, helping reduce the insects that spiders feed on around your home.
• Seal entry points: Inspect doors, windows, vents, and gaps around the foundation, pipes, and utility lines. Sealing small openings helps prevent spiders and the insects they hunt from entering your home.

Why Professional Pest Control Is the Best Long-Term Solution

Many homeowners try to solve spider problems by spraying individual spiders or knocking down webs.

While this may provide temporary relief, it usually does not solve the root cause of the problem.

Professional pest control focuses on reducing the insects spiders depend on for food while also treating common spider hiding places around your home.

At GGA Pest Management, our general pest control service targets many of the common household pests that attract spiders, including ants, cockroaches, crickets, silverfish, and other insects.

When those food sources are reduced, spider activity often decreases as well.

Routine pest control also helps prevent new pest problems before they become larger infestations, giving homeowners peace of mind throughout the year.

Keep Spiders Outside Where They Belong

Spiders play an important role in nature by helping control insect populations, but they do not belong inside your home.

With routine pest control from GGA Pest Management, homeowners throughout Waco, Temple, Killeen, and across Central Texas can enjoy fewer spiders, fewer insects, and greater peace of mind knowing their home is protected during late summer and all year long.
