Fleas can also be a source of discomfort for their human hosts; people may develop flea bites or an allergic reaction to the saliva of these pests.

As such, it’s important to know whether fleas can spread from one animal or person to another. This article will discuss the contagiousness of fleas, how they are contracted, and how to minimize transmission.

What are Fleas?

What do Fleas Look Like?

Fleas are small, dark brown, wingless parasitic insects. They measure approximately two to eight millimeters in length and have a flattened body that enables them to move through fur or feathers and fit into small spaces. Their bodies also have rows of spines that help them move around easily on their hosts.

The life cycle of a flea is composed of four stages: egg, larvae, pupae, and adult.

  • The eggs are very tiny (roughly 0.5 mm) and almost translucent in color. They are usually laid one at a time on pet fur, carpets, bed sheets, etc., and they require relative humidity of more than 50% in order to hatch within 2 weeks.
  • After they hatch they will become small, white worms which are the larvae stage who feed on organic matter from the environment such as dander from animals or dust particles from the floors.
  • Once fed enough the larvae start spinning protective cocoons until it develops into its pupae stage which can remain dormant for months until presented with conditions such as vibrations or heat which awaken it signalling that prey is nearby so that it can jump out and begin feeding again as soon as possible.
  • Finally reaching adulthood after 1-2 weeks an adult flea is reddish brown in color with large eyes adapted for active vision during darkness making them well equipped for nocturnal hunting when animal hosts are asleep and unable to fend off any attacks with ease allowing them to successfully feed without interruption.

Fleas are small, wingless parasitic insects that feed on the blood of their hosts. They can cause severe itching and discomfort for both humans and pets, so it is important to rid your home of fleas as soon as possible. Here are some tips on how to get rid of fleas:

  2. Wash infested pet bedding with hot, soapy water to kill adult and larvae fleas. You may also need to treat your pet with a topical or oral medication to control flea population on them.
  3. Use insecticidal sprays on curtains, carpets, upholstery, flooring, baseboards and other surfaces where the insect population has infested. Follow directions on label about how much product to use for desired results but generally these sprays need to be applied more than once for complete elimination of pests from an area.
  4. Encourage beneficial insect populations such as dragonflies or birds that may feed on flying adult fleas around your home environment by maintaining gardens with colorful flower or fruit trees where they can find food sources as well as nesting materials they require for living habitats near homes.
  5. Lastly, clean up any outdoor areas like decks or patios that could have been infested by larvae larvae which have been drawn in by environmental cues like humid conditions around exterior walls of buildings or moist soil beneath furniture pieces. This will help prevent future infestations since these types of insects thrive best in environments where humidity levels remain high over extended periods time making them difficult eradicate otherwise.
