Pheromones in animals are far better understood than pheromones in humans, and the entire concept of pheromone research originated in animal studies. The term itself was coined in 1959 to describe a chemical compound first identified in silkworm moths, and the framework that grew out of insect research (sex pheromones, alarm pheromones, trail markers, aggregation cues, and primer pheromones in social insects) has shaped how all subsequent pheromone work is organized. Animal pheromones are commercially exploited in pest control, in agricultural pollinator management, and in calming products for cats and dogs. The strict categories that work well for insects translate less directly to mammals and especially to humans, but the animal-pheromone literature is still where the strongest foundational knowledge lives.
What follows covers the origins of pheromone research, the main categories used to classify animal pheromones, the cluster of insect pheromones (ants, bees, wasps, spiders, moths), the queen-pheromone story in social insects, mammal pheromones in pets and other species, the vomeronasal organ across the animal kingdom, the commercial uses of animal pheromones, and how all of this compares to what’s understood about human pheromones.
Where Pheromone Research Started
The word “pheromone” didn’t exist before 1959. Two researchers, Peter Karlson and Martin Lüscher, coined the term in a two-page paper in Nature describing a new class of biologically active substances that act between members of the same species rather than within an individual body. They built the term from Greek roots: pherein (to carry) and hormon (to stimulate). Pheromones, in their definition, are chemical messengers carried outside the body that release specific reactions in receivers of the same species.
The trigger for their paper was the work of Adolf Butenandt and his team at the Max Planck Institute, who in 1959 had just chemically identified the first pheromone: bombykol, the sex attractant released by female silk moths. Bombykol drew male silkworm moths from impressive distances using just a few molecules per cubic meter of air. The female moth’s release of bombykol triggered specific flying-and-fluttering behavior in males, with effects detectable at vanishingly low concentrations.
Karlson and Lüscher’s framework defined pheromones as a category distinct from hormones. Hormones act between tissues within an organism. Pheromones act between individuals. The framework was deliberately broad enough to anticipate that pheromones would be found across the animal kingdom, from insects and crustaceans to fish and mammals.
That broader expectation has held up. Pheromones are now identified in essentially every group of animals studied at sufficient depth, with insect pheromones remaining the best-characterized and the model system for understanding pheromone chemistry in general.
The Main Categories Of Animal Pheromones
Animal pheromones are typically classified by the function they serve. The main categories that emerged from insect research, and which still organize the field, break down as follows.
Sex pheromones. Compounds released by one sex to attract or indicate reproductive readiness to the other sex. Bombykol (the silk moth attractant) is the textbook example. Most moth sex pheromones are species-specific blends of multiple compounds in precise ratios, allowing reliable mate-finding even in environments with many similar species.
Alarm pheromones. Compounds released by an animal under threat that warn or activate conspecifics. Honeybees release isopentyl acetate when stinging, which marks the target and recruits more bees to attack. Many ants and aphids have similar systems.
Trail and territory markers. Compounds deposited on the ground or on surfaces to guide other individuals to food, to mark territory, or to indicate paths between nest and resource. Ant trail pheromones from species like Solenopsis are some of the most-studied systems.
Aggregation pheromones. Compounds that attract individuals of both sexes, often used by insects to coordinate large gatherings (for feeding, mating, or defense). Bark beetles use these to coordinate mass attacks on trees.
Primer pheromones. Compounds that produce slow, hormonal, or developmental changes in receivers rather than immediate behavioral responses. Queen mandibular pheromone in honeybees, which suppresses worker reproduction, is the classic example.
These five categories overlap in some species and apply to varying degrees in others. The framework is most rigid for insects and weakens progressively as you move to mammals. The full breakdown of how these categories map onto human pheromone research is covered in the types of pheromones page.
Insect Pheromones
Insect pheromones are the most extensively studied of all animal pheromones. The major insect groups and their pheromone systems break down as follows.
Ant pheromones. Ants are the textbook case for trail pheromones: a foraging ant that finds food deposits chemical trail markers on the way back to the colony, and other ants follow the trail and deposit more markers as they go. When the food runs out, the trail evaporates and is no longer reinforced, so the colony stops sending foragers there. Ant pheromones also include alarm compounds (released when the ant is crushed) and the queen pheromones covered in the next section.
Bee pheromones. Honeybees have one of the most-studied pheromone systems in any animal. The alarm pheromone (isopentyl acetate, released when a bee stings) marks the target and triggers other bees to sting the same spot, while the Nasonov pheromone released near the hive entrance helps foragers find their way back. Queen mandibular pheromone, covered in the next section, controls colony reproductive structure.
Wasp pheromones. Wasps use alarm and aggregation pheromones similar to bees, with species-specific variation. Some social wasps release alarm pheromones from venom-gland secretions when threatened. Solitary wasps tend to rely more on sex pheromones for mate-finding.
Spider pheromones. Spiders use sex pheromones extensively, with female spiders releasing chemical attractants that males detect on their pedipalps and through specialized cuticular receptors. Spider pheromones are less studied than insect pheromones because spiders are less commercially relevant, but the underlying chemistry follows the same general pattern.
Moth pheromones. Moths are the original model system. Bombykol from silk moths was the first pheromone identified, and moth sex pheromones remain the most commonly studied system for understanding pheromone chemistry. Most moth species use blends of long-chain alcohols, aldehydes, or acetates, with species-specific ratios that allow accurate mate identification across distances of hundreds of meters.
Queen Pheromones In Social Insects
Queen pheromones are one of the most striking phenomena in animal pheromone biology. In social insects (bees, ants, some wasps), a single reproductive female (the queen) produces a chemical blend that affects the behavior, development, and reproductive physiology of every other individual in the colony.
Queen mandibular pheromone in honeybees. A blend of compounds produced by the honey bee queen’s mandibular glands. The pheromone suppresses ovary development in worker females, attracts workers to attend the queen, and broadcasts her presence and reproductive viability to the colony. Beekeepers have synthesized analogs (sometimes marketed as “temp queen pheromone” or “queen bee pheromone for sale”) for use in colony management and queen-rearing.
Queen pheromones in ants. Ant queens produce species-specific compound blends that maintain colony reproductive monopoly. A queen’s pheromones inhibit other females in the colony from becoming reproductive. When a queen dies or is removed, her pheromone signature fades and the colony rapidly responds, often by activating new reproductive females or developing replacement queens from larvae.
The general pattern. Queen pheromones are primer pheromones in the technical sense: they produce slow, hormonal, developmental changes rather than immediate behavioral reactions. The receiving workers don’t react on the spot; their physiology gets reshaped over hours to days by ongoing exposure.
This is the clearest demonstration in animal biology of pheromones doing developmental and reproductive work, not just attraction or alarm work. It’s also the system that taught researchers most of what’s known about how primer pheromones operate.
Mammal Pheromones
Mammal pheromone systems are messier than insect systems and less completely mapped, but they’re real and well-documented in many species.
Dog pheromones. Dogs use multiple pheromone systems, including territorial marking via urine (which encodes individual identity, sex, reproductive status, and social rank), alarm pheromones from anal glands, and the dog appeasing pheromone (DAP) released by lactating mothers that calms puppies. Synthetic DAP is sold commercially as Adaptil and similar products for calming anxious dogs.
Cat pheromones. Cats deposit pheromones via facial gland marking (the head-bumping and cheek-rubbing behavior most cat owners recognize). The F3 fraction of feline facial pheromones has calming effects on cats and is the active ingredient in Feliway and similar products. Cats also use urine marking, anal-gland marking, and a separate set of compounds during reproduction.
Other mammals. Pheromone systems are documented in essentially every mammal group studied at depth: rodents (especially well-studied via lab mouse research), pigs (boar pheromone androstenone, the same compound that shows up in human chemistry), horses (the flehmen response when stallions encounter mare pheromones), elephants (long-range chemical communication via temporal-gland and urinary chemosignaling), and many more.
The general pattern in mammals is that pheromone effects are layered onto regular olfactory perception rather than running through a separate channel, with the vomeronasal organ playing a role in many species but not in the strict insect-style way that the simpler pheromone systems work.
The Vomeronasal Organ Across Species
The vomeronasal organ (VNO) is a specialized chemosensory organ found in many mammals, reptiles, and amphibians, sitting just above the roof of the mouth and connected to a separate set of brain regions from the main olfactory system.
In many animals, the VNO is the primary detection system for pheromones. Snakes flick their tongues to collect chemicals and deposit them on the VNO. Cats and many other mammals show the flehmen response (curling of the upper lip to direct chemicals toward the VNO) when encountering reproductive or social pheromones.
The VNO’s role in humans is more disputed, with the human VNO being either vestigial or non-functional in most adults, and pheromone-like effects in humans likely routing through a combination of main-olfactory pathways and trace amine-associated receptors. The full breakdown is on the vomeronasal organ page.
Commercial Use Of Animal Pheromones
Animal pheromones have been commercialized for decades across multiple industries, and the keyword traffic reflects this. “Ant pheromones for sale,” “bee pheromones for sale,” and similar searches reflect real product categories.
Pest control. Pheromone lures and traps are used widely in agriculture and integrated pest management. Moth sex pheromones in particular are deployed in pheromone-confusion strategies, where high concentrations of synthetic pheromone overload male moths’ ability to find mates and disrupt reproduction. Specific commercial systems exist for crop pests including codling moth, gypsy moth, and many lepidoptera-targeted programs.
Beekeeping. Synthetic queen mandibular pheromone is used in queen-rearing operations, queen-introduction protocols, and to calm colonies during inspections. Aggregation pheromones (Nasonov analogs) are used in swarm-catching equipment.
Pet calming products. Adaptil for dogs (synthetic DAP) and Feliway for cats (synthetic F3 facial pheromone) are veterinary-recommended products for managing anxiety in pets. These products work better in some animals than others but have established commercial markets and clinical evidence behind them.
Research and academic supply. Universities and labs studying pheromone biology purchase compounds from chemical supply houses for experiments. This is a smaller market but an active one.
These commercial uses are distinct from human pheromone products. The animal-pheromone market is largely about pest control and pet welfare, while the human-pheromone market focuses on the social-attraction applications covered elsewhere on this site.
How Animal Pheromones Compare To Human Pheromones
The strict pheromone categories that work well for insects work less well for humans, and the reason has to do with how mammalian and especially human chemosensory systems evolved.
Insects are largely wired to specific pheromone responses. A male moth detecting bombykol responds with a near-stereotyped flying-and-fluttering sequence. The receiver doesn’t think about the response; the pheromone triggers a cascade that produces the behavior automatically. Most insect pheromone work has this stimulus-and-response character.
Mammals show more flexibility. A cat encountering another cat’s facial pheromone responds based on context, prior experience, and social position. The pheromone biases behavior rather than dictating it.
Humans sit at the most flexible end of this spectrum. Human responses to chemical compounds in body chemistry get filtered through learned associations, cognitive context, and individual variation that insects don’t have. The cortisol-and-mood effects from androstadienone described in the male vs female pheromones page are real, but they aren’t pheromone responses in the strict insect sense. They’re chemosignaling effects in mammals that may or may not satisfy a strict pheromone definition depending on whose framework is used.
The full breakdown of how the strict categories apply to humans is in the do pheromones actually work page. The animal-pheromone literature provides the foundation; how well it applies to humans is a separate and ongoing discussion covered in detail there.
The Bottom Line
Pheromones in animals are far better characterized than pheromones in humans, with insect systems leading the field and the foundational research dating back to the 1959 discovery of bombykol and the coining of the term “pheromone” itself.
Five main pheromone categories organize most of animal pheromone research: sex pheromones, alarm pheromones, trail and territory markers, aggregation pheromones, and primer pheromones (with queen pheromones as the textbook example).
Insects use the most rigid pheromone systems, with ant trail markers, bee colony coordination, moth sex attraction, and wasp/spider chemistry all well-documented and many of them commercially exploited.
Mammals show messier patterns, with dogs, cats, and many other species using pheromones in ways that overlap with regular olfactory perception, and with commercial calming products (Adaptil for dogs, Feliway for cats) built on identified compounds.
Humans sit at the flexible end of the spectrum, with pheromone-like effects that don’t fit the strict insect-style categorization but still respond to identifiable compounds in body chemistry.
The animal-pheromone literature is where the strongest foundational knowledge lives. Understanding it helps frame what’s known (and what’s still uncertain) about pheromones in humans.
