If you’ve got spiders in your basement, we get it — it’s tempting to light a match and walk away. But before you take drastic action, let’s talk strategy. Spiders love Idaho basements, and if you're seeing more than your fair share, you’re not alone. The good news? There are simple, proven ways to get rid of them — and even better ones to keep them out for good.
Ready for a spider-free basement? Here are 7 things you can do right now.
Spiders are drawn to dark, quiet, undisturbed places — and your basement checks every box. Add in a little moisture, a few insects for them to snack on, and maybe a forgotten cardboard box or two, and you’ve got the perfect spider hotel.
Yes, seriously. Cats are natural hunters, and they see spiders as moving toys with crunchy centers. If you're already a cat person, this might be the easiest solution on the list.
Spiders don't need a grand entrance. Tiny gaps in your foundation, doorframes, or windows are all they need. Walk around your home's exterior and seal up any cracks or crevices to keep spiders where they belong — outside.
Spiders love to spin webs in the leaves of indoor plants, where they can catch passing bugs. Check your plants every few days and relocate or rinse any eight-legged squatters you find.
Outdoor lighting attracts insects, and insects attract spiders. When possible, turn off porch lights or use yellow insect-repelling bulbs to reduce the buffet line that keeps spiders coming back.
Overgrown shrubs, leaf piles, and clutter near your foundation are spider magnets. Keep landscaping tidy and trimmed back at least a few feet from your home. It helps eliminate hiding spots and reduces access to your basement.
A torn window screen or loose door seal is like rolling out the welcome mat. Make sure all screens are intact and door sweeps are snug against the floor.
Want spiders to stay out for good? Perimeter pest control is one of the most effective ways to prevent spiders and other pests from entering your home. This service creates a protective barrier around your foundation that kills bugs before they ever make it inside.
If you're in the Idaho Falls or Boise areas, Lawn Buddies offers this treatment as part of our complete lawn care program. But wherever you're located, be sure to choose a local pest control provider that understands your region's most common pests and can apply treatments at the right times for maximum effectiveness.
Perimeter pest control focuses on prevention — stopping pests before they get in.
Lawn Buddies technicians spray around your home’s foundation, about three feet up and six feet out, creating a powerful barrier. The treatment leaves a residue that continues working for up to three months. It targets spiders, ants, earwigs, beetles, wasps, fleas, and more.
No chemicals are applied inside your home, and you don’t even need to be home during the treatment. Plus, we can apply it during your regular lawn care visits. One less thing on your to-do list.
Definitely. A full season of perimeter pest control is not only safer than DIY options, it’s also more cost-effective than calling an exterminator after you’ve got a full-blown infestation.
Treatments start at just $69 and can be bundled right into your lawn care program.
Are basement spiders dangerous?
Most are harmless, but some species (like black widows) are venomous. Either way, you probably don’t want them as roommates.
Why do spiders come into basements?
They’re looking for food (insects), moisture, and a quiet place to build a web.
Does perimeter pest control work on spiders?
Yes! It kills spiders directly and also targets the bugs they feed on.
Can I still see spiders even with pest control?
Sometimes, yes. New spiders can still wander in, but regular treatments drastically reduce the population and prevent nesting.
