Huntsman spiders are fast, active hunters that mostly eat insects and other small animals. Unlike web-building spiders, they do not sit in a sticky web waiting for food. Instead, they chase, ambush, and overpower prey using speed and venom. Their diet can include cockroaches, flies, moths, beetles, crickets, ants, and sometimes other spiders.
What Do Huntsman Spiders Eat?
Huntsman spiders mainly eat insects and other small arthropods. They are carnivores, which means they survive by catching and eating animal prey. Most of their food comes from common household and garden pests.
Huntsman spiders are especially known for eating cockroaches, which is one reason some people consider them useful around homes, sheds, and garages. They may also eat flies, moths, beetles, crickets, grasshoppers, ants, and smaller spiders.
They do not usually eat large animals. Viral stories sometimes make huntsman spiders seem more dangerous than they are, but their normal diet is made up of creatures they can overpower safely.
Common Foods Huntsman Spiders Eat
Huntsman spiders may eat:
- Cockroaches
- Flies
- Moths
- Beetles
- Crickets
- Grasshoppers
- Ants
- Earwigs
- Mosquitoes
- Other small spiders
- Small arthropods around homes and gardens
Their exact diet depends on where they live, what prey is available, and the size of the spider.
How Do Huntsman Spiders Catch Their Food?
Huntsman spiders do not build webs to trap prey. Instead, they are active hunters. Their long legs, flat bodies, and quick movement help them chase insects across walls, tree trunks, ceilings, floors, and outdoor surfaces.
They often wait quietly until prey comes close. Then they rush forward, grab the prey with their legs, and bite it. Their venom helps subdue the prey so the spider can feed safely.
Why They Are Good Hunters
Huntsman spiders are effective hunters because they have:
- Fast movement
- Strong legs
- Good hiding ability
- Flat bodies that fit into narrow spaces
- Venom for controlling prey
- Night-time hunting habits
They are most active at night, which is when many insects are also moving around. This is why people often see huntsman spiders suddenly appear on walls or ceilings after dark.
Do Huntsman Spiders Eat Cockroaches?
Yes, huntsman spiders eat cockroaches. In fact, cockroaches are one of the best-known prey items for huntsman spiders. This is one reason many people do not kill huntsman spiders when they find them in sheds, garages, or quiet corners of the home.
Cockroaches are fast, but huntsman spiders are also quick hunters. A large huntsman can catch and eat roaches when the opportunity appears. While a huntsman spider will not completely solve a cockroach infestation, it can help reduce some insect activity.
If you regularly see many cockroaches, the better solution is to improve cleaning, seal food, reduce moisture, and block entry points. Huntsman spiders may help naturally, but they should not be your only pest control method.
Do Huntsman Spiders Eat Other Spiders?
Yes, huntsman spiders can eat other spiders. They may prey on smaller spiders when they find them. Some huntsman spiders may also eat spiders that share the same hiding spaces or hunting areas.
However, other spiders are not always their main food. Huntsman spiders usually eat whatever small prey is available, especially insects. In homes and gardens, that often means cockroaches, moths, flies, crickets, and beetles.
Do Huntsman Spiders Eat Redbacks or Black Widows?
A huntsman spider may be capable of eating smaller spiders, including dangerous species, if it can overpower them. However, this does not mean huntsman spiders should be relied on to control redbacks, black widows, or other venomous spiders.
Spider interactions depend on size, opportunity, and risk. A huntsman spider will usually choose prey it can catch safely. It may avoid prey that is too dangerous or difficult to handle.
What Do Giant Huntsman Spiders Eat?
Giant huntsman spiders eat many of the same things as smaller huntsman spiders, but they may be able to take larger prey. Their diet still mainly includes insects and arthropods.
A large huntsman spider may eat bigger cockroaches, larger crickets, moths, beetles, and sometimes other spiders. In rare cases, very large huntsman spiders may catch small vertebrates, but this is not their regular diet.
Most of the time, even giant huntsman spiders feed on insects. Their large size helps them overpower prey more easily, but they are not hunting pets, people, or large animals.
What Do Baby Huntsman Spiders Eat?
Baby huntsman spiders, also called spiderlings, eat very small prey. Because they are tiny, they cannot catch the same food as adult huntsman spiders.
Young huntsman spiders may eat small insects, tiny flies, small ants, and other small invertebrates. As they grow, they can hunt larger prey. Like adults, they do not depend on webs to catch food.
Baby huntsman spiders may also face danger from other predators, including larger spiders. Not all spiderlings survive to adulthood.
What Do Huntsman Spiders Eat and Drink?
Huntsman spiders eat small animals and drink water. They get some moisture from their prey, but they may also drink small droplets of water from surfaces, plants, or damp areas.
| Question | Simple Answer |
|---|---|
| What do huntsman spiders eat? | Mostly insects and small arthropods |
| Do huntsman spiders eat cockroaches? | Yes, cockroaches are common prey |
| Do huntsman spiders eat flies? | Yes, they can eat flies |
| Do huntsman spiders eat other spiders? | Yes, sometimes |

| Do huntsman spiders eat people’s food? | No, they hunt live prey |
They do not eat crumbs, fruit, cooked food, or pantry items. If a huntsman spider is in your home, it is usually there because insects or shelter are available.
Do Huntsman Spiders Eat Ants, Flies, and Mosquitoes?
Huntsman spiders can eat ants, flies, and mosquitoes, but these are not always their preferred prey. They are more likely to go after insects that are easy to catch and provide enough food.
Flies and moths can be eaten if the spider catches them on a surface. Ants may be eaten too, but some ants can defend themselves with bites, stings, or group attacks. Mosquitoes are small, so they may not be a major food source for larger huntsman spiders.
Insects Huntsman Spiders May Eat
Huntsman spiders may eat insects such as:
- Cockroaches
- Flies
- Moths
- Mosquitoes
- Beetles
- Ants
- Crickets
- Grasshoppers
- Earwigs
- Small bugs found indoors
Their diet is flexible, which helps them survive in forests, gardens, houses, sheds, garages, and other environments.
Do Huntsman Spiders Eat Mice, Rats, or Birds?
Huntsman spiders do not usually eat mice, rats, or birds. These animals are much larger than normal huntsman prey. A typical huntsman spider is built to catch insects and other small arthropods, not mammals or birds.
Very large spiders in the world may occasionally catch small vertebrates, but this is not normal behaviour for common huntsman spiders. Claims about huntsman spiders eating rats, cats, or possums are usually exaggerated or unrealistic.
A huntsman spider may look scary because of its long legs, but its usual prey is much smaller.
Do Huntsman Spiders Eat Each Other?
Huntsman spiders can eat each other in some situations, but it is not their everyday food choice. Cannibalism may happen if one spider is much larger than another, if food is limited, or if they are kept together in a confined space.
Female huntsman spiders do not always eat males after mating. This behaviour is common in some spider groups, but it should not be assumed for every huntsman spider. Mating behaviour depends on species, conditions, and individual circumstances.
In the wild, huntsman spiders usually avoid unnecessary fights because injury can be dangerous for both spiders.
What Animals Eat Huntsman Spiders?
Huntsman spiders are predators, but they are also prey for other animals. Many creatures may eat huntsman spiders if they can catch them.
Animals that may eat huntsman spiders include:
- Birds
- Geckos
- Lizards
- Frogs
- Wasps
- Larger spiders
- Small mammals
- Chickens
- Some reptiles
Geckos and birds are common predators of many spiders. Some wasps may also attack spiders and use them as food for their young.
Can Cats and Dogs Eat Huntsman Spiders?
Cats and dogs may sometimes chase, bite, or eat huntsman spiders. Many pets are curious and may treat a moving spider like a toy. However, it is better not to let pets eat spiders.
A huntsman spider bite can cause pain or irritation, especially if the spider bites inside the mouth or on the face. Also, eating any wild spider may upset a pet’s stomach.
If your cat or dog eats a huntsman spider and seems normal, there may be no serious problem. But if your pet drools, vomits, swells, shakes, or acts unwell, contact a vet.
Can Bearded Dragons or Chickens Eat Huntsman Spiders?
Bearded dragons and chickens may eat spiders, but feeding wild huntsman spiders to pets is not recommended. Wild spiders may carry parasites, pesticides, or other contaminants. There is also a risk of bites during capture or feeding.
Pet reptiles should be fed safe, appropriate feeder insects from reliable sources. Chickens may naturally eat spiders they find while foraging, but you do not need to offer huntsman spiders as food.
For pet safety, avoid using wild spiders as regular feed.
Can Humans Eat Huntsman Spiders?
Humans can technically eat many insects and arachnids in some cultures, but huntsman spiders are not commonly eaten. Most people do not eat them, and it is not recommended to eat wild spiders.
Wild spiders may be exposed to pesticides, bacteria, or parasites. There is also no practical reason to eat huntsman spiders when safer food options are available.
In Australia, people generally do not eat huntsman spiders. They are more commonly removed from homes or left alone because they help control pests.
Should You Keep Huntsman Spiders Around for Pest Control?
Huntsman spiders can be helpful because they eat cockroaches, moths, flies, and other insects. If one is in a garage, shed, or outdoor area, it may be doing useful pest control.
However, not everyone is comfortable living with large spiders. If a huntsman spider is in a bedroom, bathroom, kitchen, child’s room, or car, it is reasonable to remove it safely.
The best approach is to relocate the spider outdoors instead of killing it. Use a container and cardboard, move slowly, and release it near trees, shrubs, or sheltered garden areas.
How Often Do Huntsman Spiders Eat?
Huntsman spiders do not need to eat every day. How often they eat depends on their size, age, temperature, activity level, and food availability.
An adult huntsman spider may go days or even longer without eating if prey is scarce. After catching a large insect, it may not need another meal immediately. Younger spiders may eat more often because they are growing.
In homes, huntsman spiders move around looking for prey. If there are few insects, they may leave and search somewhere else.
FAQs
What do huntsman spiders eat most often?
Huntsman spiders most often eat insects and other small arthropods. Their common prey includes cockroaches, moths, flies, beetles, crickets, ants, and smaller spiders. They are active hunters, so they chase or ambush prey instead of using sticky webs to trap food.
Do huntsman spiders eat cockroaches?
Yes, huntsman spiders eat cockroaches. This is one reason many people consider them useful around homes, sheds, and garages. A huntsman spider will not remove a full cockroach problem, but it may help reduce some roaches and other insects naturally.
Do huntsman spiders eat other spiders?
Yes, huntsman spiders can eat other spiders, especially smaller ones. They may also eat other huntsman spiders in certain situations, such as limited food or confined spaces. However, their main diet is usually insects, including cockroaches, flies, moths, and crickets.
What eats huntsman spiders?
Huntsman spiders may be eaten by birds, geckos, lizards, frogs, wasps, larger spiders, chickens, and some small mammals. Although huntsman spiders are skilled predators, they are still part of the food chain and can become prey for larger or faster animals.
Can cats or dogs eat huntsman spiders?
Cats and dogs may sometimes eat huntsman spiders, but it is better to stop them if possible. A spider may bite if handled or chewed, and wild spiders may upset a pet’s stomach. Contact a vet if your pet shows swelling, vomiting, drooling, or unusual behaviour.
