If you are asking whether candles attract bugs, you probably just saw ants near the jar on your counter or moths batting at a flame by the screen door. The answer depends on the bug, because each one is chasing something different in your home.

Moths and gnats fly toward the light and heat of a flame. Roaches and spiders avoid light and stay hidden. Ants follow sugar, so a candle with sweet dessert notes can lead them to your counter. Mosquitoes come for your breath and warm skin, and the candle barely registers with them. The fix is to choose a green, herbal scent and keep the flame away from open windows. That is why the hand-poured beeswax candles in our collection include scents built on herbs and leaves with nothing sugary in the blend.
Why moths and gnats fly straight at the flame
Scientists call it positive phototaxis, which means moving toward light. Many night-flying insects steer by keeping a distant light, like the moon, at a fixed angle to their eyes. That trick works when the light is far away and stays put.
A candle breaks the rule. It sits a few feet away, so every time a moth corrects its angle, it ends up a little closer. Over a few seconds, that steady correction turns into a spiral that ends at the flame. The flicker adds to the effect, because the moving light keeps resetting the insect's sense of direction.
Heat plays a smaller part. On a cool evening, a burning wick gives off a pocket of warmth that some small flies and gnats will gather around. Put the candle beside an open window or an unscreened door, and you have built a beacon for anything flying past outside.
That covers the flying insects drawn to light. The crawling pests most people worry about indoors follow the opposite rule.
Why roaches and spiders head the other way
Cockroaches show negative phototaxis, which means they move away from light. They want dark, damp, tight spaces, like the gap under the fridge or the back of a cabinet. When you light a candle at the dinner table, that part of the room gets brighter, and a roach has every reason to stay put.
So if you see roaches near a candle, look past the candle. A roach that crosses the counter at night is following crumbs or a slow drip under the sink. The candle just happens to share the room with the food.
Spiders work a little differently. They are hunters, and the light and heat of a flame do nothing for them. If you find a web in the window frame above a candle you burn every night, the spider moved there for the moths. Clear the moths, and you clear the reason it stays.
Ants are the one crawling pest where your candle can play a real part. The reason comes down to what the candle smells like.
Ants follow sugar, so the scent on your counter matters
Sugar ants find food by smell. Scouts wander out, pick up a sweet scent, and lay a chemical trail back to the nest so the rest of the colony can follow. Anything on your counter that smells like dessert or ripe fruit is worth a visit to a scout.
Many candles are built to smell exactly like that. Frosting and caramel notes are popular because people love them, and an ant reads them as a possible meal. A sticky drip of wax or a ring of residue under the jar makes the signal stronger.
Picture the morning you find a thin line of ants running along the backsplash, past the fruit bowl, toward the jar you burned the night before. You wipe it all down and toss the overripe bananas. You still want something in that spot that makes the kitchen smell good while you cook, and that spot calls for a scent with no sugar in it.
Our Slice of Life beeswax candle for the kitchen is built for exactly that counter. Its notes are Spearmint, Eucalyptus, Tomato Leaf, Anise, Mint, so it smells like a handful of fresh herbs and a just-snapped tomato stem. There is nothing in that list an ant would read as dessert. It burns from 100% beeswax on a wooden wick, so the backsplash stays free of the gray soot a paraffin candle leaves behind.
The kitchen smells green and fresh while you cook. After a week of wiping up ant trails, that is the feeling you want back in the room.
Mosquitoes follow a different signal again, and that signal is coming from you.
Mosquitoes are looking for you, which is why citronella falls short
A mosquito hunting for a meal tracks the carbon dioxide in your breath, then the heat and sweat coming off your skin. A small candle gives off a little warmth and a little carbon dioxide. A person sitting at the table gives off far more of both, so to a mosquito, you are the stronger signal.
That is also why the citronella candle on the patio table lets so many people down. Its scent spreads out too thin to form any kind of barrier. Even a light breeze carries it off before it reaches the person sitting next to it, and the effect, where there is one, covers only a small circle around the jar.
Researchers have looked closely at plant oils as mosquito repellents, and published research on plant-based repellents shows how much the results depend on concentration and air movement. A candle on a table stays a weak tool in moving outdoor air. An insect repellent on your skin, used the way the label directs, is what protects you on the deck.
So the fix for every one of these bugs starts with the space itself. The candle comes second, and the scent you pick decides whether it helps the room or sends the wrong signal.
Fix the source first, then light the candle
Here is what each pest is after, and what a candle does to it. Use it to see which step below matters most in your home.
| Bug | What draws it | What a candle does |
|---|---|---|
| Moths and gnats | Light and heat | Draws them in, especially near open windows |
| Cockroaches | Dark, damp spaces with food | Light pushes them back into hiding |
| Spiders | Other insects to eat | Nothing directly; they follow the moths |
| Ants | Sugar and sweet smells | Sweet scents and sticky drips can lead them in |
| Mosquitoes | Your breath, heat, and sweat | Very little either way |
Each step below targets what a specific pest wants. Do these first, and the candle you light afterward makes the room smell good without inviting anything in.
- Take away the food. Wipe counters at night and keep sugar and honey in jars with tight lids. Store leftovers the way the cold food storage charts suggest, so nothing sits out long enough to draw ants or roaches.
- Dry out damp spots. Roaches need water as much as food. Fix the slow drip under the sink and leave the cabinet door open for an hour after you clean it.
- Close the screens before dusk. Moths and gnats come in through gaps around doors and windows. Shut screens before you light anything after dark.
- Move the flame away from glass. A candle on the windowsill shows up from across the yard. Set it on a table toward the middle of the room, and draw the curtains if a window has no screen.
- Clean the jar and the spot under it. Wipe drips off the outside of the jar and the surface below it. A sticky ring is the part an ant scout finds first.
- Save sweet scents for rooms away from food. Keep dessert-style candles in the bedroom or the bath. Give the kitchen and the room by the patio door a green, herbal scent.
That last step is the one the candle controls. It also leads to the question most readers have on warm nights: which scent belongs in the room with the door open?
The scent for the room by the open door
On a summer evening, you might slide the glass door open, pull the screen shut, and sit in the living room as the air cools. That room sits right on the line between inside and out. It is where a sugary candle is most likely to send the wrong signal to whatever is walking along the threshold.
Our Wine Down lavender and sage beeswax candle fits that room. Its notes are Lavender, Chamomile, Sage, Rosemary, Camphor, Cedar, Sandalwood, an herbal blend with no fruit or dessert in it. The screen handles the bugs. The candle makes that end-of-day room smell calm and clean, and its herbal notes give a passing ant nothing that reads as food.
“It made my space feel cozy and refreshed at the same time. I'll definitely be purchasing it again.”
Nicole D., on Wine Down
That mix Nicole describes is what you want in a room with the door open. The scent fills the space softly, and the beeswax burns clean, so you can keep the screen shut and still sit in a room that smells fresh.
Scent is half of what a candle adds to a closed-up room. The other half is what the wax and wick release while they burn.
What a closed-up room breathes while the candle burns
When you shut screens and windows to keep bugs out, whatever the candle releases stays in the room longer. That makes the wax worth a closer look before you choose what to burn.
Most candles in stores are paraffin. Refineries start with crude oil and separate it into fuels like gasoline and diesel. A heavy, waxy residue is left near the end of that process. That residue gets bleached and then sold to candle makers. Put plainly, paraffin is petroleum waste.
Research has shown that burning paraffin releases compounds such as benzene and toluene. It also leaves the gray soot you see on walls and jar rims. Fragrance adds a second layer, since many candles use toxic fragrances that contain phthalates, a family of chemicals added to make scent last longer.
A clean candle for a sealed-up room checks these boxes:
- 100% beeswax, a single-ingredient wax with no paraffin blended in
- A wooden wick in place of a metal-core wick
- Phthalate-free fragrance
- No chemical dye
Every MBur candle checks all four, and each one is hand poured in New York City. Beeswax has the highest melting point of any candle wax, so it melts slowly. That is why the 12 oz size burns 80+ hours on its two wooden wicks.
The questions readers raise next
“But I found ants crawling right on my candle.”
Look at the jar and the surface under it. Ants on a candle are usually tracking a sticky drip or sweet residue on the glass. Wipe the jar and the counter below it, then put an herbal scent in that spot. Slice of Life was made for that counter.
“But a candle on the table seems to keep mosquitoes off.”
Any flame gives off a little heat and smoke, which can briefly confuse a mosquito near the table. That effect is small, and it breaks apart in a breeze. Use repellent and a fan for the bugs outside, then pick the candle for what it does best once you head in: making the room smell good.
“But my kitchen is big and open to the living room.”
Then size is the question. The 12 oz size has two wooden wicks, so it melts a wider pool and carries scent across a large open room. The 5 oz size, with one wooden wick and 40 hours of burn time, suits a galley kitchen or a small apartment.
FAQ
Do scented candles attract ants?
Sweet ones can. Sugar ants hunt by smell, and they read dessert or ripe fruit notes as a possible food source. Herbal and green scents give them nothing to follow, which is why our beeswax candles with green and herbal notes suit kitchens and rooms near the patio door.
Will lighting a candle bring roaches into my apartment?
No. Roaches move away from light and look for dark, damp spaces with food. If you see them near a candle, they are following crumbs or water nearby. Clear the source, then set a scent like Slice of Life on the clean counter.
Do candles keep mosquitoes away?
Very little. Mosquitoes track your breath and body heat, and candle scent drifts off in even a light breeze. Use a skin repellent outside, keep the screens shut, and light Wine Down indoors for the room you come back to.
Are moths really drawn to candle flames?
Yes. A nearby flame confuses the way moths steer by distant light, so they spiral toward it. Keep screens closed after dusk and set candles away from windows. Any candle from our beeswax candle collection works well on a table in the middle of the room.
How long do beeswax candles actually burn?
Our 5 oz size burns 40 hours on one wooden wick. The 12 oz size burns 80+ hours on two. Beeswax melts at a higher temperature than other candle waxes, so it burns slowly, and a kitchen candle like Slice of Life lasts through weeks of evening cooking.
The candle for a kitchen you just cleared of ants
Candles draw some bugs and push others away, and what sits around the flame matters more than the flame. Moths follow the light, roaches and spiders avoid it, ants follow sugar, and mosquitoes follow you. Fix the source, keep the flame away from open glass, and put a green, herbal scent where the bugs used to be.
For the kitchen, choose the 12 oz Slice of Life ($65) if you cook there most nights. Its two wooden wicks fill the room with Spearmint, Eucalyptus, Tomato Leaf, Anise, Mint for 80+ hours, so the counter where the ants used to march smells like fresh herbs every evening. Customers tell us the hours hold up:
“Candle burned slowly and was exactly the amount of hours the company said it would burn.”
Portia D., MBur customer
You are already wiping counters and sealing the sugar this week, so this is the week to set a new candle in that spot. It gives the kitchen a fresh start on the day the trail is gone.
