There is a specific kind of magic that hits the Portland suburbs in May. The air is crisp but warming, and we finally get those long-awaited stretches of sunshine that draw us out onto our porches and patios.

Whether you’re hosting a weekend BBQ or just enjoying a quiet morning in your backyard, there is one guest that is never invited: the mosquito. While we love our lush, green PNW environment, the damp spring can often lead to a buzzy backyard situation.

The good news? You don’t need harsh chemicals to claim your space back. By choosing the right plants this month, you can create a natural “no-fly zone” that looks—and smells—beautiful.

Nature’s Shield: The Power of Companion Planting

In the gardening world, we call this “companion planting.” Some of our favorite blooms do double duty; they add incredible curb appeal to your entryway while emitting scents that keep pests at bay. Most insects rely on their sense of smell to find a meal, and certain botanicals act like a natural cloaking device for your patio.

The “Big Three” Plants for Your Porch

If you are heading to a local nursery this weekend, keep an eye out for these three powerhouses that thrive in our climate:

• Marigolds: These are the colorful workhorses of a pest-proof garden. They contain pyrethrum, a compound found in many organic insect repellents. They are perfect for bordering a walkway or tucking into pots near your seating area.
• Lavender: A staple in West Linn gardens for a reason. While we find the scent of lavender incredibly relaxing, mosquitoes and moths find it offensive. It loves our well-drained soil and provides a “spa-like” aroma for your outdoor gatherings.
• Citronella Geraniums: Often labeled as the “Mosquito Plant,” these have lacy leaves and a deep lemony scent. While they aren’t hardy enough to survive a hard Oregon frost, they make excellent potted accents for your deck that you can bring inside when the temperature drops.

Beyond the Blooms: Quick Tips for a Bug-Free Zone

While your new garden additions do the heavy lifting, a little maintenance goes a long way. As you are working through your spring cleaning checklist, take five minutes to check for any standing water in gutters, birdbaths, or empty flower pots. Even a tiny amount of water can become a breeding ground after a typical May rain shower.

If you’re thinking about selling, remember that an inviting, pest-free outdoor living space is a huge selling point. Buyers aren’t just looking at the square footage; they are imagining their future lifestyle. A patio that feels like a peaceful sanctuary adds immense value to their experience.
