Beneficial vs. Pest Spiders in Tennessee: What Homeowners Need to Know

It’s natural to feel uneasy when you spot a spider. Many homeowners have a fear of these eight-legged creatures, even though most are harmless, and some are even helpful. The truth is, understanding which spiders are beneficial and which can pose risks makes it easier to feel comfortable in your home.

At All-American Pest Control, we’ve been helping Tennessee families identify and manage spiders for over 60 years. Let’s break down which spiders are good to have around, which ones to watch out for, and when it’s time to call in a professional.

Why Some Spiders Are Actually Good for Your Home

Believe it or not, a few spiders around your home can act like free pest control. Here’s why:

• A single spider eats an estimated 2,000 insects per year. That means just five spiders in your garden could eliminate 10,000 pests annually.

• Spiders often feed on mosquitoes, flies, and roaches—pests that spread germs and illness.

• Finding the occasional spider indoors can even indicate good air quality, as spiders tend to avoid polluted environments.

While no one wants dozens of spiders indoors, spotting a few isn’t always a bad sign.

Common Beneficial Spiders in Tennessee

Some spider species are actually good neighbors. Here are a few you’re most likely to see:

• Orb-Weavers (Garden Spiders): Recognizable by their large circular webs and multi-colored bodies.

• Jumping Spiders: Small, compact, and known for their quick jumps.

• Cellar Spiders (Daddy Longlegs): Thin-legged spiders often found in basements and corners of homes.

• House spiders - As it’s name suggests, these nuisance spiders are often found living in your home

These spiders rarely bite, help reduce insect populations, and prefer to stay out of your way.

When Spiders Become a Problem

While many spiders are harmless, infestations can quickly get out of hand. Signs it’s time to take action include:

• Seeing multiple spiders indoors, not just one or two.

• Finding large egg sacs or webs near entry points.

• Discovering spiders hiding in clothing, shoes, or storage areas.

• Spotting venomous species such as brown recluse or black widows.

• Feeling that their presence disrupts your peace of mind.

If any of these apply, professional pest and spider control can help restore comfort and safety in your home.

Dangerous Spiders in Tennessee to Watch Out For

Tennessee is home to two venomous spiders homeowners should be aware of:

• Brown Recluse: Light brown with a dark violin-shaped marking. Often found in attics, basements, and storage spaces.

• Black Widow: Shiny black with a distinct red hourglass on the underside of its body. Typically found in garages, sheds, and under decks.

Both species are reclusive but will bite if threatened. While bites are rarely fatal, they can cause serious symptoms. Always seek medical attention if you suspect a bite.

Common Spider Myths Debunked

There’s a lot of misinformation about spiders. Here’s the truth:

• Spiders aren’t aggressive. They avoid people whenever possible.

• Spider bites are rare. Most mysterious bites are caused by other pests.

• Most bites aren’t dangerous. Only black widows and brown recluses in Tennessee pose medical risks.

Signs It’s Time to Call a Pest Pro

If DIY efforts aren’t working or you’re dealing with venomous species, it’s best to call in professionals. You may need spider control services if you notice:

• Recurring webs and egg sacs near your home

• Frequent spider sightings in high-traffic areas

• Activity near children’s rooms or pet spaces

• A confirmed brown recluse or black widow

At All-American Pest Control, we use proven treatments that target the source of spider problems while keeping your home, family and pets protected.

How to Coexist With Beneficial Spiders

If you’re comfortable with a few helpful spiders around, here’s how to live peacefully with them:

• Remove webs from walkways but let outdoor spiders stay in less-trafficked areas.

• Don’t spray —leave treatments to professionals.

• Teach kids to respect spiders instead of fear them.

This balance helps you keep beneficial spiders while preventing infestations.
