How Spiders Sneak Into Your Home (And How to Stop Them)

Spiders don’t need a front door key. In San Antonio, they find plenty of ways into your home through gaps, cracks, and corners you don’t even think about. There are hundreds of ways how spiders can sneak into your home. While most local spiders are harmless, that doesn’t mean they’re welcome—especially not in your kitchen, bathroom, or bedroom.

Whether you’ve just spotted your first web or you’re tired of the eight-legged surprises, here’s how they get in… and what you can do to keep them out.

Spiders are predators. So as their food-- other bugs-- increase, so do they.

How Spiders Sneak Into Your Home in San Antonio

Most spiders enter your home through small, unnoticed entry points. Think: weep holes, cracks around windows and doors, gaps in siding, and even around attic vents or rooflines. Some hitch a ride inside on firewood, delivery boxes, or outdoor gear. Others simply crawl in from overgrown landscaping that touches your home’s exterior.

Common San Antonio spiders include:

• Wolf spiders – Fast, ground-level hunters. Startling, but non-aggressive.

• Jumping spiders – Small and alert with excellent vision. Tend to stick to sunny indoor spots.

• Orb weavers – Big web builders. Typically stay outdoors, but can wander in.

• Brown recluse – Uncommon, but dangerous. Hides in undisturbed indoor areas like closets, garages, or under furniture.

Once inside, spiders often settle in quiet, low-traffic areas. Closets, baseboards, attics, and bathrooms are all fair game. And while spiders eat other pests, seeing them frequently can be a sign that your home already has small insects inside acting as food sources.

Stopping Spiders Before They Get Comfortable

Spiders don’t build armies overnight, but letting a few go unchecked often leads to more. Here’s what makes the biggest difference:

• Seal up entry points. Caulk gaps, replace weather stripping, and use covers on weep holes.

• Declutter inside. Less mess means fewer places for spiders to hide and spin webs.

• Keep landscaping trimmed. Avoid bushes, trees, or vines brushing against the house.

• Treat for general pests. If spiders are hunting bugs, remove the buffet.

Pro Tip: Don’t Forget the Garage

Many spider infestations start in the garage. It’s a quiet, dusty, low-traffic space that’s almost tailor-made for web building. We always recommend de-webbing in and around garage sensors, and applying treatment in corners and around stored items.
