Fleas are insects that form the order Siphonaptera. They are wingless, with mouthparts adapted for piercing skin and sucking blood. Fleas are external parasites, living by hematophagy off the blood of mammals and birds.
Flea species include:
- Cat flea (Ctenocephalides felis)
- Dog flea (Ctenocephalides canis)
- Human flea (Pulex irritans)
- Moorhen flea (Dasypsyllus gallinulae)
- Northern rat flea (Nosopsyllus fasciatus)
- Oriental rat flea (Xenopsylla cheopis)
Over 2,000 species have been described worldwide.[2]

Morphology and behavior
Diagram of a Flea
Fleas are wingless insects, 1/16 to 1/8-inch (1.5 to 3.3 mm) long, that are agile, usually dark colored (for example, the reddish-brown of the cat flea), with a proboscis, or stylet, adapted to feeding by piercing the skin and sucking their host's blood through their epipharynx. They interestingly do not possess a mandible.[3] Their legs are long, the hind pair well adapted for jumping; a flea can jump vertically up to 7 in (18 cm) and horizontally up to 13 in (33 cm),[4] making the flea one of the best jumpers of all known animals (relative to body size), second only to the froghopper. If humans had the jumping power of a flea, a 1.8-m (6-ft) person could make a jump 90 m (295 ft) long and 49 m (160 ft) high. Their legs end in strong claws that are designed to grasp a host.[3]
Researchers with the University of Cambridge in England found that fleas take off from their tibiae and tarsi (the insect equivalent of feet) and not their trochantera, or knees.[5] It has been known that fleas do not use direct muscle power, but instead use the muscle to store energy in a protein named resilin before releasing it rapidly (like a human using a bow and arrow), with researchers using high-speed video technology and mathematical models to discover where the spring action actually happens.[5]
Atypical of other insects, fleas do not possess compound eyes but instead have simple eyes with a single biconvex lens. Their eyes are known as "eyespots". In some cases, there is no eyespot at all.[6] Their bodies are laterally compressed, permitting easy movement through the hairs or feathers on the host's body (or in the case of humans, under clothing). The flea body is covered with hard plates called sclerites.[3] These sclerites are covered with many hairs and short spines directed backward,[7] which also assist its movements on the host. The tough body is able to withstand great pressure, likely an adaptation to survive attempts to eliminate them by mashing or scratching. Even hard squeezing between the fingers is normally insufficient to kill a flea.
Fleas lay tiny, white, oval-shaped eggs better viewed through a loupe or magnifying glass. The larva is small and pale, has bristles covering its worm-like body, lacks eyes, and has mouth parts adapted to chewing. The larvae feed on various organic matter, especially the feces of mature fleas. The adult flea's diet consists solely of fresh blood.[8] In the pupal phase, the insect is enclosed in a silken, debris-covered cocoon.
Life cycle and habitat
Fleas are holometabolous insects, going through the four lifecycle stages of egg, larva, pupa, and imago (adult). Adult fleas must feed on blood before they can become capable of reproduction.[7] Flea populations are distributed with about 50% eggs, 35% larvae, 10% pupae, and 5% adults.[4]
Eggs
The flea life cycle begins when the female lays after feeding. Eggs are laid in batches of up to 20 or so, usually on the host itself, which means that the eggs can easily roll onto the ground. Because of this, areas where the host rests and sleeps become one of the primary habitats of eggs and developing fleas. The eggs take around two days to two weeks to hatch.[4]
Larvae
Flea larvae emerge from the eggs to feed on any available organic material such as dead insects, feces, conspecific eggs, and vegetable matter. In laboratory studies, some dietary diversity seems necessary for proper larval development. Blood-only diets allow only 12% of larvae to mature, whereas blood and yeast or dog chow diets allow almost all larvae to mature.[9] Another study also showed that 90% of larvae matured into adults when the diet included nonviable eggs.[10] They are blind and avoid sunlight, keeping to dark places such as sand, cracks and crevices, and bedding.[11]
Pupae
Given an adequate supply of food, larvae pupate and weave silken cocoons within 1–2 weeks after three larval stages. After another week or two, the adult fleas are fully developed and ready to emerge. They may remain resting during this period until they receive a signal that a host is near - vibrations (including sound), heat, and carbon dioxide are all stimuli indicating the probable presence of a host.[4] Fleas are known to overwinter in the larval or pupal stages.
Adult flea
Once the flea reaches adulthood, its primary goal is to find blood and then to reproduce.[12] Its total life span can be as long as one and one-half years in ideal conditions. Female fleas can lay 5000 or more eggs over their life, allowing for phenomenal growth rates. Average 30–90 days.[13]
A flea might live a year and a half under ideal conditions. These include the right temperature, food supply, and humidity. Generally speaking, an adult flea only lives for 2 or 3 months. Without a host for food a flea's life might be as short as a few days. With ample food supply, the adult flea will often live up to 100 days.[13]
Newly emerged adult fleas live only about one week if a blood meal is not obtained. However, completely developed adult fleas can live for several months without eating, so long as they do not emerge from their puparia. Optimum temperatures for the flea's life cycle are 21 °C to 30 °C (70 °F to 85 °F) and optimum humidity is 70%.[14]
Adult female rabbit fleas, Spilopsyllus cuniculi, can detect the changing levels of cortisol and corticosterone hormones in the rabbit's blood that indicate it is getting close to giving birth. This triggers sexual maturity in the fleas and they start producing eggs. As soon as the baby rabbits are born, the fleas make their way down to them and once on board they start feeding, mating, and laying eggs. After 12 days, the adult fleas make their way back to the mother. They complete this mini-migration every time she gives birth.[14]
Taxonomy

In the past, it was most commonly supposed that fleas had evolved from the flies (Diptera), based on similarities of the larvae. (Some authorities use the name Aphaniptera because it is older, but names above family rank need not follow the ICZN rules of priority, so most taxonomists use the more familiar name). Genetic and morphological evidence indicates that they are descendants of the scorpionfly family Boreidae,[15] which are also flightless; accordingly, they may eventually be reclassified as a suborder within the Mecoptera.
Their evolution continued to produce adaptations for their specialized parasitic niche, such that they now have no wings and their eyes are covered over. The large number of flea species may be attributed to the wide variety of host species on which they feed, which provides so many specific ecological niches to which to adapt. In any case, all these groups seem to represent a clade of closely related insect lineages, for which the names Mecopteroidea and Antliophora have been proposed.
Flea systematics are not entirely fixed. While compared to many other insect groups, fleas have been studied and classified fairly thoroughly, details still remain to be learned about the evolutionary relationships among the different flea lineages.

Fleas feed on a wide variety of warm-blooded vertebrates including dogs, cats, humans, chickens, rabbits, squirrels, rats, ferrets, and mice.
Direct effects of bites
Main article: Pulicosis
Fleas are a nuisance to their hosts, causing an itching sensation which in turn may result in the host attempting to remove the pest by biting, pecking, scratching, etc. in the vicinity of the parasite. Fleas are not simply a source of annoyance, however. Flea bites generally cause the formation of a slightly raised, swollen itching spot with a single puncture point at the center (similar to a mosquito bite).[16]:126
The bites often appear in clusters or lines of two bites, and can remain itchy and inflamed for up to several weeks afterwards. Fleas can also lead to hair loss as a result of frequent scratching and biting by the animal, and can cause anemia in extreme cases.[16]:126
As a vector
Besides the problems posed by the creature itself, fleas can also act as a vector for disease. Fleas transmit not only a variety of viral, bacterial and rickettsial diseases to humans and other animals, but also protozoans and helminths.[17]:72–73
- Bacteria - murine or endemic typhus:[16]:124 Fleas have helped cause epidemics by transmitting diseases such as the bubonic plague between rodents and humans by carrying Yersinia pestis bacteria.[18] Fleas can also transmit Rickettsia typhi, Rickettsia felis, and Bartonella henselae.
- Virus: myxomatosis[17]:73
- Helminth: infestation of Hymenolepiasis tapeworm[19]
- Protozoa: Trypanosome protozoans such as those of the subgenus, use a variety of flea species opportunistically as vectors.[17]:74
Fleas that specialize as parasites on specific mammals may use other mammals as hosts; therefore, humans are susceptible to the predation of more than one species of flea.[20]
A misconception concerning the carrying/transmission of the HIV/AIDS virus by fleas has been debunked by the Centers for Disease Control and Prevention (CDC). According to the CDC and other sources, it is highly unlikely or impossible for fleas to carry the virus or spread it to other humans.[21]
Flea treatments
For humans
The itching associated with flea bites can be treated with anti-itch creams, usually antihistamines or hydrocortisone.[22] Calamine lotion has been shown to be effective for itching.[23]
For pets

Modern flea control is approached using integrated pest management (IPM) protocols at the host (pet) level. IPM is achieved by targeting fleas during at least two separate life stages, with at least two separate molecules. This is typically achieved using an adulticide to kill adult fleas and an insect development inhibitor (IDI), such as lufenuron, or insect growth regulator (IGR), such as methoprene, to prevent development of immature stages.
Flea adults, larvae, or eggs can be controlled with insecticides. Lufenuron is a veterinary preparation (known as Program) that attacks the larval flea's ability to produce chitin, necessary for the adult's hard exoskeleton, but does not kill fleas. Flea medicines need to be used with care because many of them also affect mammals.
Flea treatments meant for dogs can be hazardous to cats.[24] Flea and tick ointment is also hazardous to humans; the label of a commercial preparation warns: “First aid: If on skin or clothing, take off contaminated clothing, rinse skin immediately with plenty of water for 15 – 20 minutes; call a poison control center or doctor for treatment advice. . . Although (the product is) applied only between the shoulder blades and at the base of the tail, the dog’s skin and hair oils carry the product over the entire body . . . Wash thoroughly with soap and water after handling . . .”[25]
Cedar oil, a nontoxic natural substance, has been proven effective in the eradication of infestations in pets.[26][dubious – discuss][27] However, use of some essential oils can be hazardous to cats, especially those containing phenols.[28]
Since more than three-quarters of a flea's life is spent somewhere other than on the host animal, it is not adequate to treat only the host; it is important also to treat the host's environment. Thorough vacuuming, washing linens in hot water, and treating all hosts in the immediate environment (the entire household, for example) are essential and if possible must be performed on a regular basis.[29]
Contemporary commercial products for the topical treatment of flea infestations on pets contain pesticides such as imidacloprid, permethrin, and (S)-methoprene. All flea-control products are recommended to be used at least half-yearly because the lifecycle of flea and tick can last to up to 6 months, and by using one of the flea and tick control products for so long, the infestation is highly prevented and, in the end, stopped. Although all these products are effective in fighting against flea and tick infestations, they have different active ingredients and, because cats cannot metabolize some of the compounds of the product, care must be taken in their use.
For the home
Flea infestation in the home are treated in various ways. A spot-on insecticide kills the fleas on the pet and in turn the pet itself collects and mops up newly hatched fleas. A fogger or spray insecticide containing an insect growth regulator, such as pyriproxyfen or methoprene can kill eggs and pupae, which are quite resistant to insecticides.
Flea fecal material, coiled larva, and fleas in the pupal stage combed from a cat, are also called flea dirt.
Frequent and thorough vacuuming is also helpful. The vacuum must be used around everything the animal frequents, to pick up all the larvae and eggs. Traditional advice recommends disposing of the bag after each vacuuming. One very limited experiment (only one vacuum sweeper used on a single type of carpeted surface) found that vacuuming killed 96% of adult fleas and 100% of younger fleas. This preliminary study's applicability to other circumstances is unclear.[30]
Diatomaceous earth can also be used as a home flea treatment in lieu of acetylcholinesterase inhibitory treatments or insecticides which carry with them a risk of poisoning for both humans and other animals. However, diatomaceous earth dust is harmful to pets and people when inhaled, requiring use of a dust mask to apply.[31][32][33]
Bathing dramatically reduces the flea population on a badly infested animal, especially when in combination with a mild detergent or shampoo, and brushing or combing.
Baking soda kills fleas via dehydration.[citation needed] It is safe for family and pets when used inside the home on carpets and floors, but repeated weekly treatments are required to remove an infestation completely.[citation needed] Table salt can also be used inside the home in the same way as, or in combination with, baking soda as a low-cost and safe method of breaking their lifecycle.[citation needed]
Dried pennyroyal leaves has been suggested as a traditional and natural flea control,[34] but the essential oil is toxic to mammals and should not be ingested.[35]
Borax can be used to treat flea infestations. It kills fleas by dehydrating them, but its safety for pets is untested.
Fleas cannot withstand high temperatures, so a turn through the dryer on medium or high kills fleas on clothing.[36]
Fleas can be drowned by immersion for about 24 hours; they may appear to be dead if immersed for shorter times, but can revive after some hours.[37] Soaps and surfactants can facilitate the death of fleas in bathing. The process of washing the flea (and the pet) removes integumental waxes on the flea's body and it dies from dehydration.[38][39][40]
Effects on ecosystems and humans
Approximately $2.8 billion is spent annually on flea-related veterinarian bills and another $1.6 billion annually for flea treatment with pet groomers. Four billion dollars is spent annually for prescription flea treatment and $348 million for flea pest control. Besides just economic costs to control fleas as pests, fleas provide some ecosystem services (benefits from ecosystems that support human life and well-being). Flea larvae feed on organic debris and increase the surface area of particulate matter to assist in decomposition.[41] Fleas affect human culture as well. Several examples of poems and other literature, music, and art have been created regarding fleas. Fleas were even once a source of entertainment as part of the flea circuses.[42] These circuses featured fleas performing circus acts while attached to miniature carts.
Fleas are seen as a bioterrorism weapon as they carry Y. pestis. The infected fleas feed on rodents which then infect the human population with the plague. It was reported that during World War II, the Japanese army dropped fleas infested with Y. pestis in China. The bubonic and septicaemic plague are the most probable form of the plague that would spread as a result of a bioterrorism attack that used fleas as a vector.[43]
