Our Top 10 Flowers That Repel Wasps: A Gardener’s Complete Guide

Ready to build your botanical fortress? Here are my tried-and-true favorite plants for showing wasps the door. Don’t worry—many of these are perfect for beginners and thrive in various conditions!

1. Marigolds (Tagetes)

Marigolds are a classic in any gardener’s pest-control toolkit, and for good reason. Their pungent, distinct scent, which many people find quite pleasant, is offensive to wasps and many other pests. They are cheerful, easy to grow, and come in vibrant shades of yellow, orange, and red.

Pro Tip: Plant a border of marigolds around your patio or vegetable garden. Not only does it create a beautiful edge, but it also forms a fragrant barrier that wasps are hesitant to cross.

2. Geraniums (Pelargonium)

Specifically, scented geraniums are fantastic wasp deterrents. Varieties with lemon, mint, or other strong scents are particularly effective. These flowers release their fragrance when their leaves are brushed against, making them perfect for planting along pathways or in pots near seating areas.

Pro Tip: For a powerful punch, look for the Pelargonium citrosum variety, often marketed as the “Mosquito Plant.” Its strong citronella-like scent is excellent for repelling a wide range of flying insects, including wasps.

3. Wormwood (Artemisia)

With its silvery-green foliage and strong, camphor-like scent, wormwood is a plant that wasps actively avoid. It contains a substance called absinthin, which is a potent insect repellent. Its lacy texture adds beautiful contrast to any garden bed.

Pro Tip: Wormwood can be an aggressive grower and can inhibit the growth of some nearby plants, so it’s often best grown in containers or in a dedicated herb garden where it has room to spread without bothering its neighbors.

4. Spearmint (Mentha spicata)

All members of the mint family are known for their insect-repelling properties, but spearmint is a standout for deterring wasps. Its strong, sweet scent is a powerful deterrent. Plus, you get the added bonus of having fresh mint on hand for teas and summer drinks!

Pro Tip: Never plant mint directly in the ground! It is incredibly invasive and will take over your garden. Always plant it in a container to keep its runners contained. You can even place smaller pots of mint directly on your patio tables.

5. Thyme (Thymus vulgaris)

Thyme, especially creeping varieties, is a wonderful, low-growing herb that wasps dislike. When its leaves are crushed or brushed against, they release their aromatic oils. It’s a hardy, drought-tolerant plant that works well as a ground cover, in rock gardens, or spilling over the edges of containers.

Pro Tip: Plant creeping thyme between the paving stones of your patio. Every time you walk on it, you’ll release its wasp-repelling scent right where you need it most.

6. Eucalyptus

The powerful, medicinal scent of eucalyptus is another aroma that wasps can’t stand. While most people think of giant trees, many dwarf varieties can be grown in large pots and even brought indoors during the winter in colder climates. The beautiful, silvery-blue leaves are a stunning addition to any design.

Pro Tip: Regularly snip a few branches to bring indoors. Not only will it make your home smell amazing, but the pruning will encourage the plant to become bushier and produce more of that fragrant, repellent foliage.

7. Citronella Grass (Cymbopogon nardus)

This is the famous plant whose oil is used in countless insect-repelling candles and sprays. The live plant is even more effective! This clumping grass releases a strong, lemony scent that masks the smells that attract wasps and other insects. It loves sun and heat.

Pro Tip: Citronella grass is a tropical plant, so if you live in a climate with cold winters, grow it in a large pot that you can move indoors or into a protected area once the frost hits.

8. Pennyroyal (Mentha pulegium)

A member of the mint family, pennyroyal has one of the most potent fragrances for repelling insects. It’s an effective ground cover, but it comes with a strong caution: it can be toxic to pets and humans if ingested. Plant it away from areas where pets or small children play.

Pro Tip: Due to its toxicity, pennyroyal is best used in hanging baskets or pots placed out of reach, where its scent can drift down and create a protective zone.

9. Basil (Ocimum basilicum)

Your favorite culinary herb also doubles as a wasp repellent! The sweet, pungent scent of basil is another fragrance that wasps find unpleasant. It’s the perfect plant to keep in pots right outside your kitchen door for easy access and pest protection.

Pro Tip: Plant a container with a mix of basil, thyme, and mint near your outdoor dining area. You’ll have a powerful, wasp-repelling trio that also provides fresh herbs for your summer meals.

10. Pitcher Plants (Sarracenia)

For a different, more direct approach, consider the carnivorous pitcher plant. Instead of repelling wasps with scent, it attracts and traps them. These fascinating plants lure wasps with sweet nectar, where they slip down the plant’s tube and are digested.

Pro Tip: Pitcher plants require specific care—they need boggy, acidic soil and distilled or rainwater. Growing them in a dedicated container bog garden is a great way to meet their needs and create a stunning, functional conversation piece.

Now that you have your list of plants, let’s discuss strategy. Simply having these flowers in your yard isn’t enough; knowing how to flowers that repel wasps should be planted is key. Following a few flowers that repel wasps best practices will dramatically increase their effectiveness.

  • Create Zones of Protection: Concentrate your plantings in areas where you spend the most time. Place pots of geraniums, mint, and basil on your deck, patio, and near doorways and windows.
  • Plant in Layers: Combine taller plants like eucalyptus or citronella grass in the back of a bed or large container, with medium-sized plants like marigolds and wormwood in the middle, and low-growing thyme at the front. This creates a more potent wall of scent.
  • Use Walkways to Your Advantage: Planting scented herbs like thyme and scented geraniums along paths ensures their fragrance is released every time you walk by.
  • Companion Planting: Mix these repellent flowers throughout your vegetable and flower beds. Marigolds, for example, are famous for protecting tomato plants from pests, including wasps that might be drawn to fallen fruit.

A Simple Care Guide for Your Wasp-Repelling Flowers

A healthy plant is a fragrant plant! A stressed or weak plant won’t produce the strong essential oils needed to effectively deter wasps. Luckily, this flowers that repel wasps care guide is simple to follow.

  1. Sunlight is Key: Most of these plants, especially the herbs, produce their most potent oils in full sun. Aim for at least 6 hours of direct sunlight per day.

  3. Healthy Soil, Healthy Plants: Use a good-quality potting mix for containers and amend garden beds with compost to ensure good drainage and nutrition.
  4. Prune for Potency: Regularly trimming or pinching back herbs like mint, basil, and thyme encourages them to grow bushier and release more of their fragrant oils. Deadheading flowers like marigolds and geraniums will promote more blooms.

Common Problems with Flowers That Repel Wasps (And How to Fix Them)

Sometimes, even with the best intentions, things don’t go exactly as planned. Here are a few common problems with flowers that repel wasps and some easy solutions.

Problem: “I planted the flowers, but wasps are still hanging around.”
This is the most common issue! Remember, these plants are a deterrent, not an invisible force field. Make sure your plants are mature and dense enough to produce a strong scent. Also, check for other attractants. Wasps are drawn to protein and sugar, so keep pet food covered, clean up spills promptly, and ensure garbage cans have tight-fitting lids.

Problem: “My repellent plants look weak and aren’t growing well.”
Revisit the basics in the care guide. The number one culprit is usually incorrect watering or not enough sunlight. A plant that is struggling won’t have the energy to produce the strong scents needed for pest control.

Problem: “Are these plants safe for my pets?”
This is an excellent question. While many are safe, some, like Pennyroyal and Eucalyptus, can be toxic if ingested in large quantities. Always research a plant before introducing it to an area where pets or children play. When in doubt, place them in hanging baskets or containers that are out of reach.

Frequently Asked Questions About Flowers That Repel Wasps

Do these flowers actually kill wasps?

No, they do not. The strong scents produced by these plants are unpleasant to wasps and interfere with their ability to smell food sources, so they simply choose to avoid the area. It’s a peaceful deterrent, not a weapon.

How long will it take for the flowers to start working?

You’ll notice the effects as soon as the plants are mature enough to produce a strong fragrance. For herbs, this can be fairly quick. For flowering plants, you’ll see the best results when they are actively blooming. A single, small plant won’t do much; you need a good grouping to create a noticeable effect.

Can I just use essential oils from these plants instead?

You can, but it’s a very temporary fix. A few drops of peppermint or eucalyptus oil on cotton balls can work for a few hours, but live plants provide a continuous, self-renewing source of repellent scent all season long.

Will these plants also repel beneficial insects like bees?

For the most part, no. Bees and wasps are attracted to different things. While wasps are often looking for protein (other insects) and sugary foods, bees are focused on nectar and pollen. Most of these plants, like thyme and basil, are actually very attractive to bees when flowering!

Your Peaceful, Wasp-Free Garden Awaits

Creating a garden that naturally deters wasps is one of the most rewarding projects you can undertake. You’re not just solving a pest problem; you’re adding beauty, fragrance, and life to your outdoor space in a way that is safe and sustainable.

By choosing the right plants and placing them strategically, you can transform your patio, deck, and garden beds into a true oasis. You can enjoy your morning coffee or evening meal in peace, surrounded by the beautiful sights and smells of your hard work.

So, grab your gardening gloves and a few of these powerful plants. Your beautiful, fragrant, and wonderfully peaceful garden is just a few pots away. Happy planting!
