If you want to keep wasps away from your patio, deck, or doorway without reaching for chemical sprays, smell is your most useful tool. Wasps navigate the world largely through scent — it’s how they find food, recognize their nest, and detect threats. A handful of strong aromas overwhelm or repel them, and you can use those scents to make your outdoor space far less inviting.
For non-aggressive wasps I've had great luck spraying nests with this Spectracide wasp remover in the evening. For a nest up high in an eave, soffit, or tree, this Gotcha pole adapter clamps onto the can so you can spray from the end of an extension pole and treat the nest from 10+ feet away instead of standing right under it. And for anything aggressive I wear this ridiculous-looking upper torso beekeeping suit and keep my distance. It seems silly, but trust me, I learned the hard way.
This guide covers exactly what smells wasps hate, which ones have real evidence behind them, how to mix simple DIY repellents, and — just as important — the everyday smells that attract wasps so you can avoid them.
A quick note up front: scent-based repellents are a deterrent, not a cure. They make an area less attractive and can discourage a queen from nesting, but they will not clear an established nest. If you already have an active nest, see our Get Rid of Wasps: A Homeowner’s Guide.
Wasps “smell” using their antennae, which are packed with chemical receptors. They rely on this sense to track down sugary and protein-rich food, follow scent trails, and communicate with the colony. Strong, sharp aromas — especially the volatile compounds in certain essential oils and herbs — mask those food cues and irritate the wasp’s senses, so it simply moves on to easier territory.
That’s why the smells wasps hate tend to fall into a few families: mint and menthol, citrus and lemongrass, clove and other “warm” spices, and acidic or pungent odors like vinegar.
Here are the scents most likely to keep wasps away, roughly in order of how well they hold up:
| Scent | Form to use | Evidence |
|---|---|---|
| Clove, lemongrass & geranium blend | Essential oils, diluted spray | Strongest — backed by research on nest deterrence |
| Peppermint oil | Essential oil spray, cotton balls | Good — widely reported, plausible |
| Lemongrass / citronella | Oil, candles, plants | Good |
| Eucalyptus | Essential oil spray | Moderate |
| Spearmint / mint plants | Live plants, oil | Moderate |
| Cloves & cinnamon | Whole cloves, ground spice | Anecdotal but popular |
| White vinegar | Diluted spray | Mixed — see warning below |
| Bay leaves | Crushed dried leaves | Anecdotal |
If you only try one thing, make it this blend. A combination of clove, lemongrass, and geranium essential oils is the best-supported natural wasp deterrent — research on paper wasps found that this mix discouraged wasps from building nests in treated areas. The three oils together seem to work better than any one alone.
Mix several drops of each into water with a little dish soap (to help the oils disperse) and spray it on eaves, railings, door frames, and other spots where wasps like to hover or nest. Reapply every few days and after rain.
Peppermint is the classic homeowner go-to, and for good reason — its strong menthol scent is widely reported to drive wasps off. Soak cotton balls in peppermint oil and tuck them where wasps gather, or mix a few drops into a water-and-soap spray. For a deeper walkthrough, see our dedicated guide on using peppermint oil to keep wasps away.
Lemongrass and citronella share the same lemony terpenes that wasps dislike. Citronella candles and torches add a scent barrier around a seating area, while lemongrass works as both an essential oil and a living plant in the garden.
The sharp, camphor-like smell of eucalyptus oil is another effective option. Use it the same way as peppermint — a diluted spray or scented cotton balls placed near problem areas.
Beyond peppermint oil, live mint, spearmint, and basil plants give off scents wasps avoid. Planting them in pots near doors, windows, and dining areas creates a mild, ongoing deterrent while doubling as kitchen herbs.
Whole cloves and ground cinnamon are popular folk repellents. A common DIY trick is to stud a sliced lemon or lime with whole cloves and set it out on the table during meals. The evidence here is anecdotal, but these warm spices are harmless to try.
Wasps dislike the sharp smell of white vinegar, and a diluted vinegar spray can repel them from a surface. But be careful: apple cider vinegar and sugar mixtures actually attract wasps — they’re a standard bait in homemade wasp traps. So use plain white vinegar as a repellent spray, and never leave out sweet or fruity vinegar where you’re trying to keep wasps away.
You can mix an effective scent repellent in a few minutes:
Basic recipe:
Reapply every 3–4 days and after rain, since the scent fades over time. Spray in the early morning or evening when wasps are less active, and always test a small spot first on painted or stained surfaces.

Repelling wasps is only half the battle — it helps just as much to remove what’s drawing them in. Wasps are strongly attracted to:
Simple habits make a big difference: keep garbage cans tightly sealed, cover food and sweet drinks outdoors, rinse recyclables, clean up fallen fruit, and wear unscented products when wasps are active.
Be realistic about results. Scent-based repellents are best for prevention and discouragement — keeping wasps away from a patio, deterring a queen from nesting under an eave in spring, or making a meal outdoors more pleasant. The clove-lemongrass-geranium blend has the strongest research behind it; most other scents rest on widespread anecdotal use.
What they won’t do is eliminate an established nest. Once a colony is built and defended by workers, no amount of peppermint or vinegar will remove it. For an active nest — especially a large one, one indoors, or if anyone in your household is allergic — contact a pest control professional rather than attempting removal yourself.
The most reliably effective option is a blend of clove, lemongrass, and geranium essential oils, which has research support for deterring wasps from nesting. Peppermint oil is the most popular single scent and works well for many homeowners.
Peppermint’s strong menthol scent is widely reported to repel wasps. Use it as a diluted spray or on cotton balls placed near problem areas, and reapply every few days as the scent fades. See our peppermint oil guide for details.
Plain white vinegar can repel wasps as a diluted spray because they dislike its sharp odor. Be careful, though — apple cider vinegar mixed with sugar attracts wasps and is used as trap bait, so don’t confuse the two.
Sweet and sugary smells (soda, juice, fruit, candy), protein and meat, fermenting fruit, and heavy floral perfumes all attract wasps. Keeping these covered or removed is one of the best ways to reduce wasp activity.
No. Scent repellents discourage wasps and help prevent new nests, but they will not clear an active, established nest. For nest removal, see our Get Rid of Wasps guide or call a professional.
