Can Birds Get Lice From Humans?

If you enjoy feeding and watching birds in your yard, you may have worried about picking up unwanted critters from your feathered friends. Lice are a common parasite, so can birds transmit lice to humans or vice versa?

If you’re short on time, here’s the quick answer: While humans can get lice from other humans, birds and humans typically do not share the same lice species and do not readily transmit lice to one another.

In this approximately 3000 word article, we’ll examine the types of lice that infect birds versus humans, look at the factors required for lice transmission between species, and give tips for preventing and treating lice in both birds and humans.

Different Lice Species Typically Infest Birds vs. Humans

When it comes to lice infestations, birds and humans have different species of lice that typically target them. Bird lice, also known as avian lice, are specific to birds and do not infest humans. On the other hand, humans have their own types of lice that infest different parts of the body.

Bird Lice

Bird lice are small, wingless insects that live on the feathers of birds. They feed on the bird’s blood and can cause discomfort and irritation to the bird. Bird lice are highly specialized to survive on the unique environment of bird feathers.

They have adaptations that allow them to cling to the feathers and move quickly through the plumage. These lice cannot reproduce or survive on human skin, as they are specifically adapted to the avian biology.

Human Head and Body Lice

Humans, on the other hand, have their own species of lice that infest different parts of the body. Head lice, also known as Pediculus humanus capitis, infest the scalp and hair, while body lice, known as Pediculus humanus corporis, infest clothing and bedding and only move to the body to feed.

These lice are highly adapted to human hair and clothing fibers and cannot survive on bird feathers.

Pubic Lice

In addition to head and body lice, there is also a species of lice that infests the pubic area, known as pubic lice or Phthirus pubis. These lice are specialized to survive in the coarse hair of the pubic region and cannot infest birds or other animals.

Lice Are Specialized Parasites

Lice are highly specialized parasites that have evolved to survive on specific hosts. Their bodies are adapted to the anatomy and biology of their specific host, allowing them to feed and reproduce successfully.

This specialization is why lice species are typically specific to certain animals and cannot infest others.

So, while it is possible for birds to have lice infestations, humans cannot get lice from birds, as the lice that infest birds are unable to survive on human skin or hair. It is important to understand the specific lice species that affect different animals to effectively prevent and treat lice infestations.

Requirements For Lice Transmission Between Species

When it comes to lice transmission between species, several factors need to be considered. These factors help determine whether birds can get lice from humans or vice versa.

Direct Physical Contact Needed

The transmission of lice from one species to another typically requires direct physical contact. Lice cannot jump or fly, so close proximity is necessary for them to move from one host to another. Therefore, if a bird and a human do not come into direct contact, the chances of lice transmission are significantly reduced.

According to the Centers for Disease Control and Prevention (CDC), lice primarily infest humans and animals of the same species. While lice are highly specialized parasites that have adapted to specific hosts, their ability to survive and reproduce depends on close contact between hosts.

Lice Adapted to Specific Hosts

Lice have evolved to adapt to specific hosts, which means that they are not likely to survive or reproduce on a host that they are not adapted to. For example, human lice (Pediculus humanus) are specifically adapted to infest humans and do not thrive on birds or other animals.

Similarly, bird lice (Mallophaga) are adapted to birds and are not equipped to live on humans.

Research conducted by the University of California, Riverside, confirms that lice have evolved unique adaptations to specific hosts, including specialized mouthparts for feeding and specialized claws for clinging to specific hair or feathers.

These adaptations further limit the possibility of lice transmission between different species.

Humans Rarely Have Close Contact With Birds

Another important factor to consider is the frequency of close contact between humans and birds. While there are instances where humans may interact closely with birds, such as in domestic settings or aviaries, these situations are relatively rare compared to human-human contact.

According to the American Veterinary Medical Association (AVMA), the risk of lice transmission between humans and birds is minimal due to the limited opportunities for direct contact. Humans are more likely to contract lice from other humans through activities like sharing personal items or close physical contact.

Preventing Lice in Backyard Birds

While it is rare for birds to get lice from humans, it is still important to take precautions to prevent lice infestations in your backyard birds. Here are some tips to help you keep your feathered friends lice-free:

1. Keep Feeders and Bird Baths Clean

Regularly cleaning and disinfecting your bird feeders and bird baths is essential in preventing lice infestations. Lice can easily spread from bird to bird through contact with contaminated surfaces. Make sure to clean the feeders and baths with hot, soapy water, and use a brush to scrub away any debris or droppings.

Rinse thoroughly and allow them to dry completely before refilling.

Additionally, consider rotating your feeders and baths, so you can clean one set while the other is in use. This way, you can ensure that there is always a clean and safe feeding area for your birds.

2. Isolate Infected Birds

If you notice any signs of lice infestation in one of your backyard birds, it is important to isolate the infected bird from the rest of your flock. This will help prevent the spread of lice to other birds.

You can do this by setting up a separate cage or enclosure for the infected bird until the lice infestation is treated and resolved.

Keep in mind that lice can easily transfer from bird to bird through close contact, so it is crucial to monitor your birds closely and take immediate action if you suspect an infestation.

3. Use Pesticides Sparingly

While it may be tempting to use pesticides to eliminate lice infestations in your backyard birds, it is important to use them sparingly and as a last resort. Pesticides can have harmful effects on birds and other wildlife, so it is best to explore alternative methods of lice control first.

Consult with a veterinarian or an avian specialist to determine the best course of action for treating lice infestations in your backyard birds. They can provide guidance on safe and effective treatments that are specific to the bird species you are caring for.

Remember, prevention is always better than cure when it comes to lice infestations in birds. By following these preventive measures, you can help ensure the health and well-being of your backyard birds.

Treating Lice in Humans

Dealing with lice can be a frustrating and uncomfortable experience. Fortunately, there are several effective methods for treating lice in humans. By following the right steps, you can eliminate these pesky insects and prevent their spread to others.

Medicated Shampoos and Creams

One of the most common treatments for lice is the use of medicated shampoos and creams. These products contain ingredients that kill lice and their eggs, known as nits. The active ingredients in these treatments usually include pyrethrins or permethrin, which are insecticides that target lice specifically.

When using these products, it’s important to closely follow the instructions provided and to repeat the treatment as necessary to ensure all lice and nits are eliminated.

Nit Combs

In addition to using medicated shampoos and creams, using a nit comb can also be helpful in removing lice and nits from the hair. These combs have fine teeth that are designed to catch and remove the insects and their eggs.

To effectively use a nit comb, it’s best to dampen the hair and divide it into small sections. Then, comb through each section from the scalp to the ends of the hair, making sure to clean the comb after each pass.

While nit combing can be time-consuming, it is an important step in the treatment process.

Launder Clothes and Bedding

Another crucial step in treating lice is to wash and dry all clothing, bedding, and other items that may have come into contact with lice. This includes clothing, hats, scarves, pillowcases, and towels.

Lice cannot survive without a human host for more than a day, so washing and drying these items at high temperatures will help to kill any remaining lice or nits. It’s also important to vacuum any upholstered furniture or rugs that may have been infested.

It’s worth noting that lice infestations can easily spread among close contacts, such as family members or classmates. Therefore, it’s important to notify others who may have been in close contact with the infested individual to take appropriate measures for prevention and treatment.

If you have any concerns about treating lice or if the infestation persists despite using over-the-counter treatments, it’s best to consult a healthcare professional for further guidance and treatment options.

When To Seek Medical Care for Lice

If you or someone you know has been dealing with lice, it’s important to know when it’s time to seek medical care. While lice infestations can often be treated at home, there are certain situations where professional assistance may be necessary.

Here are a few instances where seeking medical care for lice is recommended:

For Persistent Infestations

If you have tried various over-the-counter treatments and home remedies without success, it may be time to consult a healthcare professional. They can help determine if there is a more resistant strain of lice or if there are other underlying issues contributing to the persistent infestation.

They may recommend stronger prescription medications or alternative treatment options to effectively eliminate the lice.

If Infection Spreads

If the lice infestation spreads to other parts of the body or if you notice signs of infection such as redness, swelling, or pus-filled bumps, it’s important to seek medical care. Infections can occur when lice bites become irritated or when scratching leads to broken skin, allowing bacteria to enter.

A healthcare professional can assess the situation, prescribe appropriate medications to treat the infection, and provide guidance on how to prevent further complications.

For Help Identifying Lice Species

There are different species of lice that can infest humans, such as head lice, body lice, and pubic lice. While they may all cause similar symptoms, the treatment and prevention methods can vary. If you’re unsure about the type of lice you or someone else has, seeking medical care can help in correctly identifying the species and providing the most effective treatment plan.

Healthcare professionals have the knowledge and expertise to distinguish between different lice species and offer appropriate guidance.

Remember, seeking medical care for lice is not always necessary, but it can be beneficial in certain situations. If you’re unsure about what steps to take or if your lice infestation is causing significant distress, don’t hesitate to reach out to a healthcare professional for assistance.

They can provide the necessary support and guidance to help you effectively deal with the infestation.


While lice infestations can be annoying, birds and humans typically host different lice species that are adapted to their specific biology and grooming habits. Maintaining cleanliness and seeking treatment when needed can control outbreaks.

With proper precautions, bird lovers can continue to enjoy feeding their backyard flocks without much concern about swapping lice with their feathered friends.
