Every August, my house seems to collect heat, humidity, and a weird mix of summer smells all at once. Between soccer cleats by the mudroom bench, the dog coming in from the yard, a bathroom that never fully dries out, and a kitchen that works overtime, I’m always looking for simple ways to make the whole place feel fresher without plugging in six different gadgets. So when I heard people swear that setting out bowls of whole cloves could help with odor, bugs, and that heavy “closed up summer house” feeling, I decided to test it the only way I know how: all in, room by room, for 21 straight days.
I put a small bowl of whole cloves in every room of my house during one of the hottest stretches of August, when outdoor temperatures hovered between 86 and 94 degrees most afternoons and the humidity felt relentless. I kept notes on what changed, what absolutely did not change, how strong the scent stayed, whether bugs seemed affected, and whether this was actually worth the cost. Here’s exactly what happened in my suburban Midwest house, including the rooms where cloves worked surprisingly well and the spots where I’d skip them next time.
1. Why I tried it in the first place
I’m a working professional, so I love any home experiment that is low effort, low cost, and doesn’t require me to remember a 14-step routine after a long day. Whole cloves checked those boxes. I bought a bulk bag because I use cloves for cooking anyway, especially in fall baking and spice blends, and I figured if the experiment flopped, I could still use the leftovers.
The other reason I chose August is that it’s the toughest month in my house. By then, the AC has been running for weeks, windows stay mostly shut, and certain rooms develop their own personality. The entryway gets musty from damp shoes. The upstairs bathroom gets steamy. The guest room starts to smell stale because nobody’s in it much. If cloves were going to prove themselves, August was the time.
2. Exactly how I set up the test
I used 9 rooms total: kitchen, living room, primary bedroom, guest bedroom, home office, upstairs bathroom, downstairs powder room, entryway, and laundry room. In each space, I placed 1 small open bowl with 2 to 3 tablespoons of whole cloves. Most bowls were about 4 inches wide and shallow enough to let the scent release easily.
I bought roughly 14 ounces of whole cloves, which cost me $11.99 at an international grocery store. That gave me enough to fill all the bowls and still have some extra for refreshing weaker rooms later. I placed the bowls out of reach of kids and pets, mostly on high shelves, dressers, or countertops away from food prep areas. I did not crush the cloves at first because I wanted to see what whole cloves alone would do.
3. What the house smelled like on day 1
On the first day, the scent was immediate in smaller rooms and pretty subtle in larger ones. The powder room and upstairs bathroom smelled warm, spicy, and noticeably fresher within about 30 minutes. Not “perfumed,” not candle-like, just clean in a dry, cozy sort of way.
In the living room and kitchen, though, the effect was much lighter. If I stood near the bowl, I could smell it clearly. Sitting on the couch 8 or 10 feet away, not really. This was my first clue that cloves are not some magical whole-house fragrance fix. They work best in compact spaces, especially where air doesn’t move much.
4. The rooms where cloves worked best
The clear winners were the upstairs bathroom, downstairs powder room, guest bedroom, and laundry room. These were all spaces where stale or damp air can hang around, and the cloves seemed to gently shift the smell without overpowering it. In the guest room, especially, the “closed room” odor was much less noticeable by day 3.
My laundry room surprised me most. It tends to pick up a mix of detergent, warm appliance air, and occasional mildew notes from damp towels. The bowl of cloves didn’t erase every smell, but it made the room feel less sour. That room is about 7 by 8 feet, so one bowl with 3 tablespoons was enough to make a difference.
5. The rooms where I barely noticed a difference
The kitchen and living room were the least dramatic. That makes sense in hindsight. My kitchen has too many competing smells: coffee at 6:30 a.m., lunch prep, onions sautéing, dish soap, trash, and whatever leftovers are in the fridge. A bowl of cloves simply can’t outcompete all that in a busy room.
Same story in the living room. It’s the largest shared space in the house, open to the dining area, with ceiling fans moving air around constantly. The bowl smelled nice up close, but it did not make the room as a whole smell different. If you’re expecting one little bowl of cloves to freshen 300 square feet of open-concept space, I don’t think that’s realistic.
6. What happened to odor control over 21 days
This was the most noticeable benefit. The cloves didn’t “remove” odors the way deep cleaning does, but they helped soften mild stale smells in low-traffic rooms. I’d compare it to opening a drawer and catching a faint spice scent instead of a flat, dusty smell. Subtle, but real.
By around day 10, the bowls in the bathrooms and laundry room still had a scent, but it was less obvious from the doorway. By day 14, I refreshed 4 of the 9 bowls by lightly stirring the cloves and adding about 1 extra teaspoon to each. That perked them back up. In my notes, I wrote: “Better at supporting freshness than fixing a dirty room.” That pretty much sums it up.
7. Did it help with bugs?
This was the part I was most curious about because summer in the Midwest means fruit flies trying their luck in the kitchen, random gnats by windows, and the occasional ant scouting mission. I did not see a dramatic, scientific-level drop in bugs across the whole house. I want to be honest about that.
What I did notice was that the entryway and laundry room seemed to have fewer tiny flying bugs hovering than usual, but I can’t say for certain cloves were the reason. I was also cleaning counters more often because I was already in “experiment mode,” and that definitely matters. In the kitchen, fruit fly activity only improved after I wiped the sink drain, emptied the compost bin nightly, and kept produce in the fridge. So for bugs, I’d call cloves a maybe, not a dependable solution.
8. How the heat affected the cloves
The August heat actually seemed to help the scent release, especially in warmer rooms. On afternoons when the upstairs got a little toastier, even with the AC on, the bowl in the guest room smelled stronger than it did in the morning. Heat can make aromatic spices more noticeable, and I think that worked in the cloves’ favor.
That said, high heat did not make the scent last forever. By the third week, the cloves looked a bit duller and drier, and their fragrance was softer overall. In other words, heat may help them throw more scent at first, but you still have a limited useful window. In my house, 10 to 14 days was the sweet spot before a refresh made sense.
9. The one adjustment that made the biggest difference
Halfway through, I tested a trick in two rooms: I gently cracked a small portion of the cloves with the back of a spoon before putting them in the bowl. Not powdered, not crushed into dust, just lightly broken. That made the scent noticeably stronger within an hour.
I did this in the home office and guest room. The office is where I spend a lot of my workday, and the stronger clove scent made the space feel a little more intentional and less like “the room where unopened mail goes to die.” If I repeat this experiment, I’ll use mostly whole cloves with 1 teaspoon lightly cracked on top for better fragrance.
10. What I learned about placement
Placement mattered more than I expected. Bowls placed low, tucked behind objects, or near breezy vents didn’t do much. Bowls set on a dresser, shelf, vanity, or countertop at about waist to chest height performed better. My best results came from surfaces 3 to 5 feet off the ground and away from direct airflow.
I also found that putting the bowl near the source of odor helped. In the laundry room, I placed it beside the hamper area. In the bathroom, it sat near the vanity rather than on a far windowsill. In the entryway, it worked best on the console table near the door instead of on a back shelf in the coat closet.
11. Cost, effort, and whether it felt practical
For me, this was one of the cheapest home experiments I’ve done. Spending about $12 to cover 9 rooms was reasonable, especially since I didn’t use fancy containers. I just used small prep bowls and ramekins I already owned. Setup took maybe 20 minutes total, including deciding where to put everything.
The upkeep was also manageable. Every 5 to 7 days, I checked the bowls while doing my normal weekend reset. If a room had gone scent-blind, I stirred the cloves or added a little more. That is exactly my kind of home habit: easy to attach to routines I’m already doing, like changing hand towels or running a load of sheets.
12. The downsides I ran into
The first downside is obvious: if you don’t like the smell of cloves, this is not for you. It’s warm, spicy, and a little old-fashioned. I happen to like it because it reminds me of holiday baking and chai, but scent is personal. In one room, my husband said it smelled “like a craft store in November,” which was not entirely wrong.
The second downside is that cloves can create a false sense of freshness if you let them. They are not a substitute for cleaning fabric, taking out trash, scrubbing drains, or dealing with moisture problems. In the upstairs bathroom, the bowl helped the room smell nicer, but the real improvement still came from washing bath mats and running the exhaust fan for 20 minutes after showers.
13. Where I would use cloves again
I would absolutely use them again in small bathrooms, guest rooms, linen closets, and the laundry room. Those are the spaces where they gave the best return for almost no effort. I’m also considering putting a tiny bowl inside the coat closet in winter, when everything gets trapped indoors and heavy.
I would skip them in the kitchen unless I was pairing them with a very specific seasonal vibe, like around the holidays. Even then, I’d see them as a background scent, not a practical odor fix. For the living room, I’d only bother if I used a larger bowl, more cloves, or a combination of cloves and other dried aromatics, but that turns into a different project.
14. My best tips if you want to try this yourself
Start with the rooms that need the most help, not every room all at once. If I were recommending a beginner version, I’d say use 2 tablespoons of whole cloves in 3 spaces: one bathroom, one bedroom, and one utility area like a laundry room or mudroom. Give it 7 days and see if you even enjoy the effect.
Use shallow bowls, keep them dry, and place them somewhere safe and visible so you remember to monitor them. If the scent fades, stir them first before adding more. And if your goal is odor control, clean the source at the same time. Cloves work best as a finishing touch, not a rescue plan.
15. So, what actually happened after 21 days?
After 21 days, my house did not transform into some naturally perfumed bug-free sanctuary, and I’m glad I didn’t expect that. What did happen was smaller and, honestly, more useful: several rooms smelled less stale, the bathrooms felt fresher between cleanings, and the laundry room improved enough that I kept that bowl out even after the experiment ended.
I also learned that cloves are one of those old-school household tricks that work best when you use them with realistic expectations. They’re inexpensive, simple, and pleasantly effective in the right spaces, especially during late-summer heat when rooms can start to feel stuffy. For me, that makes them worth repeating. Not everywhere, not forever, but definitely in a few hardworking corners of the house that need a little help in August.
