Do Parrots Need To Be Wormed?

Worms, such as roundworms and tapeworms, are internal parasites that become lodged in the digestive system of their hosts.

Once they reach the bloodstream, they can spread to other organs to find nutrients. This enables them to reproduce and live out their life cycle while the parrot gives worms to other pets and humans.

Parrots must be dewormed every 3-6 months with worming medicines.

Although indoor parrots are rarely exposed to the same environment as wild birds, they remain susceptible to parasites. Your parrot may get infested by poop from other birds, dirty water, or contaminated food.

Worm infestations can affect any parrot, regardless of the cleanliness of your bird’s living environment. So, be consistent in your parrot’s worming routine and check for any warning signs.

In most cases, worm infestations lead to malnutrition and anemia, which can be fatal if left unchecked.

Do Parrots Get Worms?

Parrots can get worms, usually helminths (intestinal parasites).

There are countless breeds and subspecies, but they can be broken into three main categories:

  • Cestodes
  • Nematodes
  • Trematodes

These enter the body through an infested surface or food. Once inside your parrot, helminths will begin to enter the organs. These macroparasites are very small but can still be viewed with the naked eye.

Some worms have evolved to target the digestive tract, while others prioritize the blood vessels.

Types Of Worms That Affect Parrots

While there are different parasitic worms, you’ll find your parrot only encounters four:

  • Ascars (roundworms)
  • Capillaria (hairworms)
  • Cestodas (tapeworms)
  • Acuarias (gizzard worms)

Ascarids (Roundworms)

Ascarids (roundworms) are transmitted when a parrot ingests worm eggs. This usually happens when interacting with infested poop from other animals or touching an infested surface.

Roundworms settle into the digestive tract, where they cause a blockage. The ascarid larvae can move to other tissue where they live as larvae cysts. These thick shells will form around the larvae as a capsule.

Not all parrots are susceptible to a roundworm infestation, but the following increase their vulnerability:

  • Being young
  • Overly stressed
  • Playing or roaming on the ground, especially in the dirt
  • Having free access to wild birds in aviaries
  • Spending time on dirty, damp cage floors

Roundworms can survive in an environment for an extended time, so it’s difficult to eradicate them.

It’s also difficult to diagnose a roundworm infestation in parrots during the early stages of infection, so you’ll have to wait until ringworm starts causing more obvious symptoms.

Capillaria (Hairworms)

Hairworms are threadlike worms that live in the throat or lower intestinal tract.

Humans can’t get these, so there’s no danger of your parrot getting them from you or giving them to your family. However, all it takes to pass on worms is contact with infested animal poop.

This infestation is difficult to treat but has fewer harmful effects than ascarids. In most cases, the eggs can be seen in the parrot’s feces, which is the most effective means of early detection.

Cestoda (Tapeworm)

Tapeworms like damp environments. Unlike other types of worms, they won’t appear in your bird’s feces. Your parrot likely ingested tapeworm through food or water that contained tapeworm eggs.

Also referred to as flatworms, these parasites are excreted as segments, which is the only way to detect them early. There are many different kinds of tapeworm, ranging from 2-3 millimeters to 50-60 millimeters. The more they feed on your parrot, the larger they’ll grow.

Once your parrot is infested, it’ll have mild symptoms. If this continues without treatment, it may be fatal. Tapeworms remove the nutrients from your parrot’s body, resulting in starvation.

Acuaria (Gizzard Worm)

The gizzard worm mainly targets your parrot’s gizzard.

Insects will eat the eggs of this parasite, especially weevils or slaters. The larvae worm starts to develop within the insect as its first host. Your parrot may eat the bug without realizing that it’s contaminated.

Once inside your parrot’s body, acuaria will multiply. Early in its lifecycle, this parasite will seek nutrients, finding its way to the gizzard and burrowing through the gizzard lining.

Although acuaria takes the nutrients your parrot relies on to remain healthy, most will die from a different infection. Their gizzard will be more vulnerable to other bacteria once the gizzard worm population has grown significantly.

How Do Parrots Get Worms?

Wild birds come into contact with all types of worms in their environment.

According to the Journal of Zoo and Wildlife Medicine, caged birds are highly susceptible to cross-contamination. If one parrot gets infested by worms, it’ll soon pass them on to other birds.

Caged parrots don’t have wide-open flying spaces or lofty nesting places to spread out. They can’t limit contact with each other’s feces or infested food.

Here are the causes of worms in parrots:


Parasites can contaminate food sources, especially grain-based.

Check your supply for webbing or pupae.


Worms can thrive in damp spots or water bowls in a bird cage, so wipe down the parrot’s enclosure and change its water regularly.


Most parasites are transmitted through feces, so when your parrot poops in its cage, its cage mate is put at risk. Your other parrot will likely get worms if any waste gets into its food, water, or toys.

Wild Birds

In a caged environment, worms normally only occur due to interacting with wild birds and introducing infected items to the cage.

Since nothing will naturally deworm a wild crow or pigeon, it may carry worms for its entire lifespan.

When a wild bird poops in the grass that a parrot plays in or consumes food a parrot eats, it can become worm-infested.

Symptoms of Worms in Parrots

According to Farmer’s Weekly, the symptoms depend on the type of worm. The signs may be more or less obvious, depending on where the parasite is in its lifecycle.

The symptoms of worms in parrots include:

  • Diarrhea
  • Vomiting
  • Irregular bowel movements
  • Intestinal blockages
  • Weakness
  • Loss of appetite
  • Weight loss
  • Heavy mucus on droppings

If you check your parrot’s feces, you may be able to see the worms.

However, if they’re early in their lifecycle, this will be more difficult. The parrot may become anemic, depressed, or moody in extreme cases.

In most cases, your parrot will sleep a lot and appear excessively hungry. No matter how much your parrot eats, it’ll never be enough.

Worming Treatment for Parrots

The treatment of worms in parrots involves:

  1. Cleaning your parrot’s cage, toys, and perches
  2. Changing all food and water
  3. Isolating the parrot from other pets or birds
  4. Picking the right deworming medicine
  5. Applying deworming medicine to food or water
  6. Treating the parrot for several weeks until the symptoms clear up
  7. Sanitizing anything that the parrot comes into contact with

Most worms can be treated with over-the-counter medicine, but the side effects of worms can’t. If your parrot has an intestinal blockage, anemia, or is malnourished, a veterinarian may need to intervene.

Can I Use The Same Wormer Every Time?

Switch up your worming products because worms can build up resistance. Some worming products are mild, and you may need to repeat the treatment 10 to 12 days later to ensure all worm eggs are removed.

Does Deworming Always Work?

With a heavy infestation, worming doesn’t always lead to direct recovery. There may be worms in the parrot’s intestines, clogging up the system and preventing them from expelling the dead worms.

Deworming Medicine for Parrots

Select a deworming medicine that treats the broadest range of parasites. It’s easy to confuse the symptoms of one type of worm with another, and your parrot may be hosting several parasites at once.

Heavy Worming

Beaphar bird wormer is one of the most popular veterinary medicines for heavy worming. Other brands like Piperazine and Levamisol are also good choices.

The Beaphar bird wormer is recommended because it contains levamisole hydrochloride (1% w/v). It’s an effective compound against roundworms and hairworms.

Levamisole should only be administered under the guidance of a vet.

Light Worming

Wormout Gel is effective because it combines Praziquantel and Oxfendazole.

These are used to target common parasites and intestinal worms in larger species of parrots. Ivermectin is a cost-effective wormer for internal and external parasites, usually in smaller parrots.

Deworm your parrot every 3-6 months. If your parrot lives indoors only and doesn’t have contact with any wild birds, every 6 months will suffice.

However, for parrots that share a space or play outside, deworming every 3 months will be necessary.
