Let’s get your garden back to being the peaceful retreat it was meant to be!

First, Let’s Understand Our Unwanted Garden Guests: The Red Wasp

Before we can effectively deter them, it’s helpful to know a little about our adversary. Red wasps are a type of paper wasp, known for their reddish-brown color and slender bodies. While they aren’t typically aggressive when foraging for food, they are extremely protective of their nests.

If you get too close to their home—often built under eaves, in sheds, or on porch ceilings—they will defend it fiercely. Understanding what attracts them is the first step in sending them packing.

Why Are They in My Garden?

Red wasps are drawn to your garden for the same reasons you are: it provides everything they need to survive and thrive. They are primarily looking for three things:

  • Shelter: They seek out protected, elevated spots to build their paper-like nests. Think overhangs, deck railings, hollow fence posts, and even dense shrubs.
  • Food: Adult wasps feed on nectar, but they are also voracious predators. They hunt caterpillars, spiders, and other soft-bodied insects to feed their young. This is their one redeeming quality in the garden!
  • Water: Wasps need water to drink and to mix with wood fiber to create the pulp for their nests. Bird baths, leaky hoses, ponds, and even pet water bowls are all attractive sources.

The Best Offense is a Good Defense: Proactive Prevention Tips

The absolute most effective way how to keep red wasps away is to make your garden an undesirable place for them to set up shop in the first place. A little preventative maintenance in the spring can save you a world of buzzing headaches in the summer. These are some of the how to keep red wasps away best practices every gardener should know.

Seal Up Potential Nesting Spots

Take a walk around your home and yard with a “wasp’s eye view.” Look for any sheltered nooks and crannies that would make a perfect home. Think like a real estate agent for pests!

Use caulk or sealant to fill cracks in siding, gaps around window and door frames, and openings where utility lines enter the house. Check under the railings of your deck, inside sheds, and even inside unused barbeque grills or birdhouses. A little effort here goes a long way.

Manage Your Garden’s Food and Water Sources

While wasps help with pest control, you don’t want to roll out the red carpet for them near your living areas. Be mindful of open food and water sources.

Always use tight-fitting lids on your trash and compost bins. If you have fruit trees, be diligent about cleaning up any fallen fruit from the ground. During outdoor picnics or BBQs, keep sugary drinks and protein-rich foods covered until you’re ready to eat.

The Power of Decoys

Here’s a fantastic, simple trick: wasps are incredibly territorial. They will rarely build a new nest within 200 feet of an existing one. You can use this to your advantage by hanging fake wasp nests.

You can buy these online or at garden centers—they look like simple, grey paper lanterns. Hang one or two in early spring under the eaves of your porch, garage, or shed. To an approaching queen looking for a new home, it signals that the territory is already claimed, and she’ll likely move on. This is a cornerstone of any eco-friendly how to keep red wasps away strategy.

Harnessing Nature’s Power: Eco-Friendly How to Keep Red Wasps Away

As gardeners, we love working with nature, not against it. Fortunately, there are many powerful, sustainable how to keep red wasps away methods that don’t involve harsh chemicals. This is the heart of our how to keep red wasps away guide—using plants and natural solutions.

Repellent Plants for Your Garden Beds and Containers

Many beautiful and fragrant plants do double duty by naturally repelling wasps. Consider adding a few of these to your garden, especially in pots on your patio or near seating areas.

  • Mint Varieties: Spearmint and peppermint are incredibly offensive to wasps. They are vigorous growers, so it’s best to plant them in containers to prevent them from taking over your garden.
  • Thyme: Specifically lemon thyme, this lovely groundcover releases a scent wasps dislike when you brush against it. Plant it along pathways or in pots.
  • Wormwood: This silvery-leafed plant contains a compound called absinthe, which is a powerful insect repellent. Don’t worry—it’s perfectly safe to have in the garden.
  • Eucalyptus: The strong, medicinal scent of eucalyptus is another great deterrent. It grows into a beautiful tree but can be kept small in a large pot.
  • Citronella & Lemongrass: Famous for repelling mosquitoes, the strong citrus scent of these grasses also works wonders on wasps.

Don’t worry—these flowers are perfect for beginners! Just give them a sunny spot and regular water, and they’ll help protect your space.

DIY Essential Oil Sprays

You can concentrate the power of these repellent plants into an easy-to-use spray. In a spray bottle, mix a cup of water with a few drops of dish soap (this helps the oil stick) and 15-20 drops of one or a combination of the following essential oils:

  • Peppermint Oil
  • Clove Oil
  • Lemongrass Oil
  • Geranium Oil

Shake well and spray this mixture on surfaces where wasps tend to build nests, like under eaves, porch ceilings, and window frames. Reapply every week or after it rains.

Common Problems When Trying to Keep Red Wasps Away (And How to Solve Them)

Sometimes, even with our best efforts, we run into challenges. Here are some common problems with how to keep red wasps away and how to troubleshoot them like a pro.

Problem: They Keep Coming Back to the Same Spot!

You got rid of a nest, but a few weeks later, a new one is being built in the exact same location. This happens because wasps leave behind pheromones that signal “this is a good place to live.”

The Solution: After you knock down an old nest, you must thoroughly clean the area. Use a scrub brush with a strong soap and water solution, or a 50/50 mix of white vinegar and water, to remove any lingering scent cues.

Problem: My Repellent Plants Don’t Seem to Be Working.

You planted a single mint plant on the far side of your patio and wasps are still showing up for your lemonade.

The Solution: Scent-based repellents are all about concentration. You need enough plants to create a “scent barrier.” Cluster several repellent plants together in pots near your seating areas. For an extra boost, gently crush a few leaves with your fingers when you’re sitting outside to release a fresh wave of their essential oils.

The How-To Guide: Safely Dealing with an Existing Red Wasp Nest

Discovering a wasp nest can be alarming, but don’t panic. If you must deal with one yourself, safety is the number one priority. This is a critical part of any how to keep red wasps away tips collection.

Step 1: Assess the Situation

First, evaluate the nest. Is it small—about the size of a golf ball—and in an easily accessible location? Or is it a large, established colony the size of a dinner plate tucked high up in your roofline?

Important Safety Warning: If you are allergic to insect stings, do not attempt to remove a nest yourself. If the nest is large, aggressive, or located in a difficult spot (like inside a wall), call a professional pest control service. Your safety is not worth the risk.

Step 2: Choose Your Time and Tools

If you’ve determined the nest is small and manageable, timing is everything. Wasps are least active and all inside the nest during the cooler temperatures of night or very early dawn. Never attempt removal during the heat of the day.

Wear protective clothing. This means long sleeves, long pants tucked into socks, closed-toe shoes, thick gloves, and a hat or hood. You want as little exposed skin as possible.

Step 3: The Removal Process (For Small, Accessible Nests ONLY)

  1. Purchase a can of wasp and hornet spray specifically designed to shoot a stream from 15-20 feet away. Never get close.
  2. Following the can’s directions, approach the nest slowly at night and thoroughly saturate the nest opening with the spray.
  3. Do not stand directly underneath the nest. Approach from the side.
  4. Leave quickly and do not return to the area until the next day.
  5. The following day, observe the nest from a safe distance. If you see no activity, you can use a long pole to knock it down.
  6. Dispose of the nest and, as mentioned earlier, clean the area to remove pheromones.

Frequently Asked Questions About Keeping Red Wasps Away

What scent do red wasps hate the most?

Wasps have a strong sense of smell, and they despise potent, minty, and spicy scents. Peppermint oil is widely considered one of the most effective and powerful natural repellents you can use against them.

Will killing a red wasp attract more?

Yes, it absolutely can. When a wasp is swatted or crushed, its body can release an “alarm pheromone.” This chemical signal acts like a distress call, alerting other wasps from the colony to the danger, which can trigger an aggressive swarm. It is always better to use deterrents than to swat.

Are red wasps good for anything in the garden?

Surprisingly, yes! In the broader garden ecosystem, red wasps are beneficial predators. They hunt and feed on many common garden pests, including caterpillars that chew on your vegetable leaves. The goal of this guide isn’t to eradicate them from your property, but to use these how to keep red wasps away tips to manage them and keep them far from your home and outdoor living spaces.

How can I tell the difference between a red wasp and a bee?

It’s easy to tell them apart once you know what to look for. Wasps have very slender, smooth bodies with a distinctly narrow “waist” between their thorax and abdomen. Bees, on the other hand, are typically plumper and covered in fine, fuzzy hairs to help them collect pollen.

Your Peaceful Garden Awaits

Reclaiming your garden from red wasps is entirely within your reach. By focusing on prevention, making your yard less attractive to them, and using the power of nature’s own repellents, you can create a space where you feel safe and relaxed.

Remember to be proactive in the spring, be mindful of what attracts them, and always, always prioritize safety if you have to deal with an existing nest.

Now you have the knowledge and tools to create a peaceful, buzz-free oasis. Happy gardening!
