Abell Pest Control Guide to identifying common household spiders

Let’s be honest, spiders don’t exactly win popularity contests. Most people would much rather see them outside doing their own thing than crawling around inside the house. And while most spiders you’ll find at home are harmless, there are a couple that can pose a real risk if disturbed.

Knowing which spiders are just hanging out and which ones need to be taken seriously can help you stay calm and safe. Here’s a simple guide to the most common spiders you're likely to find indoors.

Harmless Spiders

American House Spider

If you spot messy, tangled webs in corners that remind you of Halloween decorations, chances are you’ve got an American House Spider nearby. They have long, thin legs and small, oval-shaped bodies. These spiders keep to themselves and rarely cause any issues.

Daddy Long Legs

Also known as cellar spiders, these guys are easily recognized by their tiny bodies and extremely long, delicate legs. You’ll often find them in damp, dark places like basements or crawl spaces. Despite the myths, they’re completely harmless and physically unable to bite humans.

Jumping Spider

These small, compact spiders are usually black with pale markings and short legs. True to their name, they’re known for their quick, hopping movements. You might see them around sunny windowsills where they hunt for insects. They can bite if provoked, but their bites aren’t dangerous.

Wolf Spider

Big, hairy, and fast-moving, wolf spiders can be alarming to see, but they’re not looking for trouble. Usually brown with pale stripes, you’ll find them low to the ground, often near baseboards, under furniture, or outside under rocks and firewood. They’ll only bite if they feel threatened.

Spiders to Be Cautious Around

Black Widow

The female black widow is easy to spot - glossy black body with a red or orange hourglass shape on her underside. These spiders tend to stay hidden in quiet, undisturbed areas like sheds, garages, or woodpiles. Their bite is venomous and can cause sharp pain and muscle cramps, so if you spot one, keep your distance and don’t try to handle it.

Brown Recluse

Light to dark brown with a violin-shaped marking on its back, the brown recluse prefers dark, tight spaces, such as closets, attics, and behind furniture. Their bites can lead to serious skin reactions and should be treated by a medical professional right away. If you see one, avoid contact and take care when cleaning out storage spaces.

The Bottom Line

Most spiders you find in your home are harmless and may even help by eating other bugs. But if you come across one of the dangerous types, or start noticing more spiders than usual, it’s worth taking a closer look at your space. Keeping things clean, dry, and clutter-free is the best way to avoid unwanted eight-legged visitors.
