Adult fleas (both male and female) require a blood meal prior to mating. They prefer blood from your pet, but in the absence of a canine or feline host, fleas will bite people. Once mated, the female flea may deposit up to 50 eggs per day on your dog or cat.
Do both male and Female lice feed on blood?
Both male and female bedbugs feed on the blood of sleeping persons at night. In the absence of humans they feed on mice, rats, chickens and other animals.

How do fleas move?
Based on their observations, fleas achieve their fast motion by releasing the energy locked up around their thorax region, by pushing their legs down their toes and leaping up.
Why is it not a problem for fleas to navigate around the fur of a host?
Navigating the way around the fur of a host is never a problem for the flea because of its size and hair, which works like a velcro dart.
Why do fleas grow?
They may increase in size due to the amount of food they consume. A flea’s body and senses are developed to make it capable of looking for a host, moving onto the host to build a residence, feed on the host in a way that it can stay nourished after many days, and the nourishment can sustain its offspring.

What is a cat flea?
Ctenocephalides canis and C. felis are the dog and cat flea, respectively. Members of this genus are 3-4 mm in length, laterally-compressed and reddish-brown to black in color. The two species can be separated by the characteristics of the head and setae on the hind legs: C. canis has a head that is strongly-rounded anteriorly, and have hind tibiae with eight setae bearing notches; C. felis has a more-elongate head and hind tibiae with six setae bearing notches. Both species possess pronotal and genal combs (ctenidia). Ctenocephalides spp. are of medical importance as vectors of rickettsial diseases, including Rickettsia typhi, and may serve as intermediate hosts for tapeworms, including Hymenolepis and Dipylidium.
How do fleas live?
Fleas, like other holometabolous insects, have a four-part life cycle consisting of eggs, larvae, pupae, and adults. Eggs are shed by the female in the enviroment . Eggs hatch into larvae in about 3-4 days and feed on organic debris in the environment. The number of larval instars varies among the species. Larvae eventually form pupae , which are in cocoons that are often covered with debris from the environment (sand, pebbles, etc). The larval and pupal stages take about 3-4 weeks to complete. Afterwards, adults hatch from pupae and seek out a warm-blooded host for blood meals. The primary hosts for Ctenocephalides felis and C. canis are cats and dogs, respectively, although other mammals, including humans, may be fed upon. The primary hosts for Xenopsylla cheopis are rodents, especially rats. In North America, plague ( Yersinia pestis) is cycled between X. cheopis and prairie dogs. Humans are the primary host for Pulex irritans.

Can fleas cause itching?
Infestation by fleas may cause severe inflammation of the skin and intense itching. Although many animals acquire partial immunity after constant or repeated attacks, individuals (especially humans) can occasionally become sensitized after exposure and develop allergies. Species that attack people and livestock include the cat flea ( Ctenocephalides felis ), the so-called human flea ( Pulex irritans ), the dog flea ( Ctenocephalides canis ), the sticktight flea ( Echidnophaga gallinacea ), and the jigger, or chigoe, flea ( Tunga penetrans ). Poultry may be parasitized by the European chicken flea ( Ceratophyllus gallinae) and, in the United States, by the western chicken flea ( Ceratophyllus niger ).
Can Fleas Survive If My Pet Is Away?
You might think you can beat a flea infestation by simply removing your pet from the home for a while. After all, no host, no parasite, right? But fleas are clever pests. A fully formed adult flea can sit tight inside its cocoon for a year, just waiting for a host animal to reappear. The fleas stay safely in their pupal cases until they sense vibrations that suggest an animal is moving nearby. Like many insects that feed on blood, they can also sense an increased presence of carbon dioxide, which signals that a host is in the area.
What is the most common flea in a dog?

Is the Cat Flea a Public Health Risk?
Bites of cat fleas can be very annoying to humans because chemicals in flea saliva stimulate an immune response that causes itching. The same immune response can be much more severe in dogs and cats, possibly producing a serious allergic response known as flea bite allergy in susceptible pets. You should take pets suffering from this condition to a veterinarian for treatment and consultation about approaches to flea control.
How Can I Recognize a Flea?
They possess very large hind legs that are used for jumping and a very slender proboscis (beak) that extends forward when the flea takes a blood meal. At rest, the proboscis projects downward and backwards between the legs, but it cannot be seen without the aid of a microscope. Similarly, recognition of flea larvae and pupae typically requires the use of a microscope. To the unaided eye, the legless larvae resemble tiny whitish "worms." Flea pupae most likely would not be recognized at all because they are encased within a sticky cocoon covered by incorporated soil particles and small items of debris from the habitat in which the larvae develop.
Where Are Cat Flea Larvae and Pupae Found in Homes and Yards?
Cat flea larvae and pupae are found in and around areas where pets are active and where they sleep . Indoors, common sites include pet sleeping mats, among fibers of thick carpets, in upholstered furniture, and on bed covers, if pets are allowed to sleep there. Outdoors, under warm and humid conditions, cat flea larvae and pupae can develop in certain sites were pets frequently rest. One of the most common is in moist, shaded soil beneath shrubs. Another site is in the small amount of soil found in joints of concrete walks and porches.
What Should I Know About the Feeding Habits of Cat Fleas?
Male and female adults feed only on the blood of warm-blooded animals, and they may take as many as 10-15 blood meals per day. Bites on humans usually occur on the ankles and calves. Multiple bites that are more or less in a row are characteristic of repeated feeding by a single flea and not necessarily indicative of an infestation of numerous fleas. Similar to other blood-sucking insects, adult cat fleas respond to carbon dioxide emitted by warm-blooded animals. They also are stimulated by floor vibrations, which cause them to jump and tumble through the air, increasing the possibility of landing on an approaching pet or person. Measurements reveal that adult cat fleas are capable of jumping upward and outward at least 12 inches.
How Do Pets Become Infested and Pet Owners Get Bitten?
Adult cat fleas usually reside and feed on a single host dog or cat. Pet to pet transfer occurs when pets interact and when they sleep together, but transfer of cat fleas from infested pets to pet owners appears to be uncommon. The usual way in which a human gets bitten by a cat flea is when a "hungry" adult emerges from its pupal cocoon and jumps onto a person walking in their vicinity. The presence of flea bites on a person suggests that the home (or a barn) is supporting the development of flea larvae, which can be a continuous source of adult fleas that then infest your pets.
How Do Cat Fleas Survive Winter in Indiana?
Only adult cat fleas appear to be capable of surviving winter in Indiana. Some adults may continue to infest pets during winter, but the most common hosts appear to be wild mammals such as coyotes, raccoons, and opossums. Cat flea eggs, larvae, and pupae are not known to survive winter outdoors and typically are not found indoors during winter.
How Do Humans Influence Cat Fleas?
Pet owners contribute to the success of cat fleas by failing to monitor their pets for the presence of adult fleas and by failing to practice sanitation methods that reduce the development of flea larvae. Again, cat flea larvae and pupae are found in and around areas where pets are active and where they sleep. Owners should keep these areas clean (see below), and periodically launder pet sleeping mats and bed spreads, if pets sleep on them.
How to protect yourself from flea bites?
If you accidentally break your skin, keep the area clean by washing it with soap and water and covering your flea bites with a bandage. Talk to your healthcare provider if you have an infected flea bite.
