Say Goodbye to Mosquitoes, Flies and No-See-Ums – These 8 Fragrant, Pest-Repellent Plants Make Patios So Much More Enjoyable in June
Perfectly placed pots with scented with oils that pests hate and you love will change your outdoor gatherings this summer.
June is when patio season actually gets going, and also when mosquitoes, flies, and no-see-ums (also called biting midges) show up in force. The two things are connected — warmth drives both — and for a lot of people the bugs win. A spray handles it for a few hours. These plants handle it differently, and the space ends up better for having them in it.
The mechanism is real enough: volatile oils in fragrant plants interfere with how insects find food and hosts. Getting a handle on which bugs are actually causing problems is part of dealing with common garden pests effectively but for general patio use, this list covers most of what shows up in June.
Let's explore what you can plant to have a swat-free summer.
Fragrant Plants That Help Repel Patio Pests
These eight plants make this list — some that show up in every garden center and a couple that tend to get overlooked despite working just as well. All of them hold their own near outdoor seating, whether in containers or tucked into a border close to where people actually sit.
1. Lavender
The reputation is deserved, though the mechanism gets oversimplified. It's not just that lavender smells nice to people and bad to bugs — it's specifically the linalool in lavender oil that mosquitoes and flies avoid. June bloom pushes the oil concentration up, so the repellent effect peaks right when the patio gets the most use.
Container placement close to seating does more work than a lavender hedge planted at the garden's edge — proximity matters here. A 2-in-1 patio planter and bench from Amazon let's you sit right between the plants where they'll do the most good. Lavender does best in the heat with well-drained soil left to dry between waterings.
2. Lemongrass
Citronella candles use a synthetic version of what lemongrass produces naturally, which is worth knowing. The plant releases oils continuously from the foliage without needing heat, and the scent runs cleaner than any candle version of it. Tender in most climates — put out after frost risk passes, back inside before fall. They get big fast; a single clump in a large pot can hit 4 feet (1.2m) by midsummer. Brush the leaves when the ambient effect feels light. That releases a second wave of oil that carries for a while.

3. Rosemary
Camphor is the active compound in rosemary, and mosquitoes and flies don't like it. As a passive container plant it offers background deterrence — useful against flies in particular. The effect jumps when stems get disturbed or burned, which is why some people toss a sprig onto a grill fire. Beyond the pest angle, rosemary holds its structure through summer heat better than most herbs, so it pulls its weight as a container plant visually too. Give it infrequent watering, full sun, and it pretty much runs itself. Find heirloom rosemary seeds from Sow Right Seeds on Amazon.
4. Scented Geranium
Not the standard bedding geraniums — the scented-leaf types, which smell nothing like the flowers and everything like citrus, rose, or mint depending on variety. Citrus-scented ones work best against mosquitoes. The oils are in the leaves and release on contact, so placement where people brush past — near chair arms, along a path edge — gets more out of them than a pot sitting in a corner. These are tender perennials that overwinter well indoors. Find a 'Fingerbowl Lemon' scented geranium from GingersGreenhouse on Etsy.
5. Marigold
Pyrethrum is the compound — the same one extracted for use in commercial insecticides — and marigold foliage produces it in amounts that register to mosquitoes, aphids, and whiteflies at very close range. French types run more potent than African ones and stay compact enough for container use. Get them in now and they'll carry through to fall. There's a secondary benefit worth mentioning: whitefly pressure on nearby edible plants tends to drop when marigolds are close, which is a practical bonus if herbs or vegetables share the patio space.

6. Basil
Estragole and linalool are the relevant oils in basil — both put mosquitoes and flies off, and neither requires the plant to be touched to work. Sweet basil is widely available and does the job; lemon basil runs hotter on the citrus end and may edge it out against flies. A pot on the table is about as close-range pest deterrence as it's possible to get, and it doubles as a herb within arm's reach. Pinch the flowers off regularly — once basil bolts, the oil production drops, and so does the effect. Find Genovese sweet basil seeds from Sow Right Seeds on Amazon.
7. Peppermint
Menthol is broad-spectrum against pests — mosquitoes, ants, and flies all avoid it — which puts peppermint ahead of some narrower options on this list. Containers are the right approach anyway since it spreads aggressively in the ground. Brushing against the plant releases a significant oil burst, so anywhere foot traffic is regular is a good spot. A raised bed from Walmart establishes the right growing conditions and keeps it from spreading into the rest of the garden. Keep it in its own container — it crowds out neighboring plants fairly quickly if given shared space.
8. Lemon Verbena
Sharper and more volatile than lemon balm, more immediate than lemongrass — lemon verbena has a citrus scent that mosquitoes and flies find genuinely off-putting rather than mildly inconvenient. The oils are most active when the foliage is warm and in direct sun, which happens to be the same window when patio usage peaks. It gets shrubby and fairly large by late summer given decent conditions. Frost-tender, so it comes in for winter — though honestly, even without the pest repellent angle, it's worth growing near a seating area just for what it smells like on a warm afternoon.
