While most common garden worms are harmless, some brown worms, specifically certain species of invasive hammerhead worms, are toxic.
Hammerhead worms do not bite, but they do secrete a poisonous chemical as a form of protection against predators. This chemical may cause skin irritation in humans who come into contact with the worm.
If you've spotted little brown worms in your house that curl up when disturbed, you're most likely looking at millipedes. While they're not actually worms, these arthropods are often mistaken for worms because of their long, segmented bodies and habit of rolling into a tight coil when touched.
It's very unlikely a single accidental worm will kill a healthy person, but ingesting contaminated or parasitized worms can cause severe infections or foodborne illness in rare cases.

Threadworms look like tiny pieces of white cotton. Roundworms look more like earthworms. Hookworms can cause a red worm-shaped rash. The twisted shape of the worm is raised and easy to see.
Soil-transmitted helminths are parasitic worms that infect humans who come into contact (either by eating contaminated food or by walking barefoot in infected areas) with worm eggs or larva in soil.
Jumping worms have a negative impact on soil structure. Their feeding creates a more porous soil (water moves through quickly) reducing moisture content. Jumping worms also easily spread to new garden areas by hitchhiking in contaminated soil and compost.
Brown stomach worm (Teladorsagia circumcinta) is a roundworm that affects sheep and goats. It can cause major damage if it is not identified and treated timely. Distribution: It is a major parasite of the winter rainfall area.
In some cases, drain worms can also crawl up from the drain. Putting a piece of sticky tape over part of the drain is one way to test whether or not you have drain worms in that particular drain.
Answer: What you may have found are carpet beetle larvae. They are characteristically brown, they may look banded with brown and pale stripes, and with long ”hairs” at the tail end. They are slow moving across walls and floors.
Dog or cat roundworm can cause toxcariasis, an infection that mostly doesn't cause symptoms, but in some people, they may have a fever, cough, abdominal pain and eye damage. You can get toxcariasis through contact with dog and cat poo and contaminated dirt.
What do hammerhead worms look like? The head of these flatworms resembles that of a hammerhead shark, hence the name. They have a yellowish-brown striped body and can grow well over a foot long.
Haemoglobin contains iron, which means most worm blood – including that of earthworms and leeches – is red.
Our results demonstrate that earthworms can efficiently take up prions and act as vectors of prion disease transmission. In worms exposed to prion-contaminated soil, we noted PrPSc competent for both in vitro prion replication and in vivo infectivity.
In contrast to a popular urban legend, erythorbate is NOT made from earthworms, though the U.S. Department of Agriculture reports receiving many inquiries about erythorbate's source. It is speculated that the similarity in the spelling of the words “erythorbate” and “earthworms” has led to this confusion.
Most worms you'll encounter won't pose any threat to you or your pets. These include earthworms, redworms, nightcrawlers and more.
Most often, the infection is caused by eating food or drinking water that is tainted with roundworm eggs. Ascariasis can cause symptoms such as stomach pain, vomiting, fever and cough. Serious health issues called complications can happen if many worms grow inside the body.
Explain that worms are fragile animals and can be hurt easily, so they must be handled with gentleness.
At night, the female adult worms deposit their eggs outside the rectum near the anal area. One way to detect pinworms is to shine a flashlight on the anal area. The worms are tiny, white, and threadlike. If none are seen, check for 2 or 3 additional nights.
Worms have five hearts, shaped like arches. These arches help pump blood through the worm's body – a pretty simple task due to its shape. Worms are cold blooded, meaning they can't control their body temperature, which will be the same as their surroundings.
