Cicadas are large, distinct-looking insects with bulging red eyes and veiny orange wings. They are well-known for their buzzing mating calls, which can be a nuisance to some and music to the ears of others. Every 17 years, billions of these insects descend upon the US, simultaneously damaging and benefiting the environment. Despite their fearsome appearance, they do not bite or sting. So, are cicadas attracted to perfume?

What You'll Learn
Cicadas are attracted to upright, dark silhouettes, like trees
While there is no evidence that cicadas are attracted to perfume, these insects are attracted to upright, dark silhouettes, like trees.
Cicadas are known to be attracted to trees, which serve as a place for them to congregate, mate, and lay eggs. According to entomologist and cicada expert Eric Day, "Cicadas land on people because they strongly resemble trees... Insects that utilize trees are strongly attracted to upright dark silhouettes, and a human standing in an open area is close enough." This attraction to upright, dark objects helps explain why cicadas may land on people, mistaking them for trees.
The physical characteristics of cicadas also contribute to their attraction to trees. With a typical length of 0.8" to 2 inches, they are large enough to be easily noticed. Their broad heads feature large, bulging compound eyes, with three additional simple eyes called ocelli. Their wings are often tinted with colors like green, brown, or black, which help them blend in with their natural surroundings, such as tree bark or foliage.
Cicadas play a significant role in ecosystems. They provide natural pruning of trees and help return nutrients to the soil when their bodies fall to the ground after mating. Their loud mating calls, produced by males, can be a nuisance to some, but they also signal the arrival of summer and are a fascinating part of the natural world.
While cicadas are attracted to trees and similar silhouettes, they do not appear to be attracted by scent. Therefore, scent blockers or insect repellents targeting scent receptors are unlikely to be effective in repelling them. Instead, physical barriers like mosquito nets or long-sleeved clothing can provide some protection when spending time outdoors during a cicada emergence.

They are not attracted to scent or perfume
While cicadas are attracted to humans, it is not because of the scent or perfume that a person might be wearing. Rather, it is because they mistake humans for trees. Cicadas are attracted to upright, dark silhouettes, and humans standing in open areas fit the bill. This is why you will rarely see a cicada on the ground.
Cicadas are large insects, reaching up to 2 inches in length. They have orange, veiny wings and bulging red eyes. They are found worldwide, with the highest diversity in tropical regions. They are known for their distinctive buzzing or clicking sounds, which males produce to attract mates.
Cicadas are not attracted to scents or perfumes, but they are attracted to the buzzing noise of machinery. If you are using noisy equipment, you may find that cicadas are attracted to the noise and come closer to you. However, this is not because of the scent but because of the noise.
To prevent cicadas from being attracted to you, you can avoid using noise-making objects. If you must use them, do so early in the morning or late in the evening when the cooler air temperatures make cicadas less active. You can also wear long-sleeved clothing to prevent them from crawling on your skin.
In summary, cicadas are not attracted to scent or perfume. They are attracted to the silhouette of a human, which they mistake for a tree, and to the noise of machinery, which may sound similar to their mating call. To avoid attracting cicadas, you can reduce noise and wear long sleeves when outdoors.

Male cicadas produce a buzzing mating call to attract females
Male cicadas produce a distinctive, loud, buzzing mating call to attract females. The sound is often described as a rhythmic, high-pitched whine. The purpose of the loud noise is to attract females for mating, and the volume helps the males to be heard over the background noise of other cicadas, reaching potential mates over long distances.
The mating call is produced by the rapid clicking of the male cicada's tymbals—membranes on the insect's abdomen. The intensity and frequency of the noise can vary depending on the species, temperature, and time of day. For example, periodical cicadas are most active during the day and emerge in large numbers during the warmer months, usually between late spring and early summer.
Once a mate is found, male cicadas change their song to indicate that they are now part of a couple. Females of most cicada species do not have sound-producing organs, but they do have hearing organs called "tympana" on the underside of their abdomens.
Some male cicadas also respond to female wing-flick signals, increasing their number of calls to improve the odds of eliciting a response from nearby females. This behavior has been observed in North American Magicicada species.
Contrary to popular belief, cicadas are not attracted to perfume or human scent. Instead, they are attracted to upright, dark silhouettes, which they mistake for trees—their natural habitat.

Cicadas are attracted to trees for mating and laying eggs
Female cicadas lay their eggs in the wood of branches, making slits in the branch with their egg-laying apparatus and placing the egg inside. They lay one to several dozen eggs in a single branch before moving to another branch or tree. This egg-laying activity lasts approximately 30 days, and about 6 to 7 weeks later the eggs hatch into tiny white nymphs. The nymphs fall to the ground and burrow into the soil to feed on grass roots and, eventually, tree roots for the next 13 or 17 years.
The branches that female cicadas lay their eggs in can become severely weakened by the slits made during the egg-laying process. This can cause the branches to snap off in the wind, resulting in flagging damage to the tree. However, cicadas will not kill mature trees and shrubs they lay their eggs on. Any damage caused by hatching larvae should be minor and temporary.
To prevent cicadas from landing on trees in your orchard, you can apply insecticides such as neonicotinoids. You can also delay planting and postpone winter pruning of trees to avoid cicada emergence and decrease the probability of damage to incipient scaffold limbs.

They are attracted to dark colours like black, brown and green
While there is no evidence to suggest that cicadas are attracted to perfume, these insects are attracted to dark colours, particularly black, brown, and green. This is because these colours help them blend in with their natural surroundings, such as tree bark or foliage.
Cicadas are often attracted to trees, where they congregate, mate, and lay eggs. They are drawn to upright, dark silhouettes, which is why they may land on people. A human standing in an open area resembles a tree to a cicada, and these insects will go towards any dark, upright object.
The colour of cicadas varies, with some being green, brown, or black, and others a combination of these shades. Some species may also have vibrant markings or patterns on their wings or bodies, including orange, red, blue, or yellow. These colours help cicadas camouflage, making them difficult for predators to spot.
While scent does not attract cicadas like it does mosquitoes, they are attracted to the buzzing noise of power tools and lawnmowers, which may be similar to their mating call. This is why you may find cicadas swarming towards you if you are operating such equipment.
To avoid attracting cicadas, it is best to avoid using noise-making objects. If you must use them, do so during the cooler times of the day, such as early morning or late evening, when cicadas are less active. Wearing long-sleeved clothing can also prevent them from crawling on your skin.
