It’s spider season in the Pacific Northwest—the time between September and November where orb weavers, giant house spiders, and more come out to mate and wind up, well, everywhere.

Spiders show off their large webs on trees and plants, patio furniture, doorframes, and anywhere between. They eventually make their way into homes and nestle into corners, onto walls, and the occasional bedsheet or blanket. And while I appreciate how beneficial these critters are for the environment, I can’t help but shudder at the sight of each creepy crawly slowly encroaching on my home.

I’ve always lived in apartment complexes that were likely treated with some sort of chemical to keep spiders at bay. So aside from the odd spiderweb in my entryway or balcony, spider season never impacted me…until now.

This is my first spider season in my new home and the spiders are starting to take over. I’m not willing to treat my property with any chemicals that harm beneficial insects, so I’ve been on the hunt for an all-natural way to reclaim some of my outdoor space and stop spiders coming into my home. Here's the best organic spider control product I've found—and it costs less than $20.

The Spider Prevention Super-Ingredient

While peppermint is a well-documented pest deterrent, I don’t always have the time to DIY a solution. Enter Mighty Mint Insect & Pest Control Spray, which is available at most large retailers including Amazon, Target, and Walmart.

With 4% high-concentration peppermint, Mighty Mint Insect & Pest Control Spray stops spiders in their tracks. Plus, mint repels other pests, like insects and rodents as well. That gives me great peace of mind because our home has also had wasp and rodent issues in the past. And with over 45,000 positive reviews, it’s safe to say this spray works.

I opted for the Mighty Mint Insect & Pest Control Spray because it doesn't kill spiders, it simply repels them. However, if you’re looking for something heavier duty, try Mighty Mint Peppermint Oil Spider Spray. It contains 3% peppermint and 1% geraniol, which kills spiders when sprayed directly on them.

There are fragrant plants that repel spiders, too, but they're not as effective as this concentrated spray.

This Spray Is Safe & Really Works

This spray has been a saving grace in my home. When I first sprayed it, I was shocked to see how many spiders scuttled out of cracks and crevices around my windows and doorframes. I literally watched this product repel them out of my house. This spray is an absolute must for Pacific Northwest pest control.

I have two cats, as well as several neighborhood cats, dogs, and deer that roam through our yard on any given day. So I wanted to make sure anything I used would be safe for these creatures. This organic pest control spray is all-natural, 100% plant-based, as well as kid and pet-friendly.

I’m also very sensitive to smell and develop headaches easily. I can honestly say that this spray smells great—no strong, headache-inducing chemical smells here. When I came back inside after I sprayed around the house, my husband actually told me I smelled like Christmas.

Where to Spray for Spiders

If I could pressure wash my entire home with this stuff, I would. But since I can't, here are the key spots to spray to keep spiders out of the house:

  • Front & back porches: We haven’t quite hit the rainy season in the Pacific Northwest yet and still have a few more weeks of sunny afternoons. But my front and back decks, along with all of my patio furniture, have become home to the spiders. Luckily, Mighty Mint Insect & Pest Control Spray smells great and doesn’t trigger my headaches, so I can still hang out on my freshly-sprayed deck.
  • Door & window frames: Can you blame me for seeing a large opening to the outside and wanting to spray it? I’ve seen so many spiders set up shop around my doorframes and windows, so spraying around them is a no-brainer—especially if you don’t have screens.

  • In and around crawlspaces: This is where we’ve seen wasps and rodents make their homes. This spot also gives critters easy access to our walls and pipes. It was obvious we needed to treat our crawlspace with this spray. Be sure to also spray around any exterior vents into your crawlspace and laundry room, as this is how wasps wound up in ours.
  • Water spouts: This sounds like a nursery rhyme, but spiders actually do climb up the water spout! Ever since we found three different spiders nestled around our hose and on our water spout, my husband has fully taken over watering our plants. But not anymore! After a light spritz of peppermint spray on our downspouts, I’ve been able to get back to what I love: taking care of our new yard and hoping all of our first-year plants are happy and healthy.
  • Around trashcans: We’ve seen some spiders form intricate webs across and around our garbage/recycling/yard waste bins. So I gave them all a good spray. Now I don’t have to fear potentially tracking a spider or two back into the house.

You can also spray anywhere inside your home—along baseboards, vents, windowsills, and even lightly spritz your couch or blankets.

So if you live in the Pacific Northwest or if you’re seeing increased spider and insect activity around your home during the change of seasons, be sure to pick up Mighty Mint Insect & Pest Control Spray.
