Top 7 Scariest Spider In The World

Our team has prepared an amazing list with all the information about these arachnid friends. Let’s take a look together:

1. Brazilian Wandering Spider (Phoneutria)

(Phoneutria)

One of the world's creepiest spider, the Brazilian Wandering Spider, scientifically known as Phoneutria, is often cited as one of the most dangerous spiders in the world due to its potent venom. Here are some key facts about this species:

Potent Venom: The venom of the Brazilian Wandering Spider can cause serious medical issues, including intense pain, inflammation, and in severe cases, even death if not treated promptly. Its venom contains a powerful neurotoxin that can affect the nervous system.

Aggressive Nature: Unlike many spiders that tend to retreat, the Brazilian Wandering Spider can be quite aggressive when threatened. It is known for its defensive posture where it raises its front legs high in the air.

Habitat: This spider is primarily found in South America, particularly in Brazil, but also in parts of Uruguay, Paraguay, and Argentina. It thrives in a variety of habitats, from banana plantations to urban areas.

Nocturnal Behavior: The Brazilian Wandering Spider does not build webs to catch prey. Instead, it roams the ground at night, hunting for insects, other spiders, and sometimes small amphibians and reptiles.

Human Encounters: Due to its wandering nature, this spider sometimes enters homes and can be found in dark, hidden places during the day. Its tendency to hide in banana bunches has led to it being nicknamed the "banana spider."

2. Sydney Funnel-Web Spider (Atrax robustus)

Sydney Funnel-Web Spide

The Sydney Funnel-Web Spider is one of the worlds scariest spider. Scientifically known as Atrax robustus, is another highly venomous spider, notorious for its threat to humans, particularly in the Sydney region of Australia. Here are some important details about this species:

Highly Venomous: The venom of the Sydney Funnel-Web Spider is extremely toxic to humans and can cause severe symptoms, including intense pain, muscle spasms, and in untreated cases, can be fatal. It contains a complex mix of toxins that affect the nervous system.

Distinctive Appearance: This spider is typically dark in color, ranging from blue-black to brown or even plum hues. Males, which are more dangerous than females due to their more potent venom, are usually smaller and more slender.

Burrowing Habit: Unlike wandering spiders, Sydney Funnel-Web Spiders build funnel-shaped webs in moist, shaded areas. These webs have a characteristic funnel entrance leading into a burrow where the spider resides.

Aggressive Defense: When threatened, the Sydney Funnel-Web Spider shows an aggressive posture, rearing up its front legs and showing its fangs. Despite this, they only bite when provoked or accidentally disturbed.

Urban Encounters: As Sydney has expanded, encounters with these spiders have increased, especially during warmer months when males wander in search of mates. This has led to increased awareness and the development of antivenoms which have significantly reduced fatalities.

3. Black Widow Spider (Latrodectus mactans)

Black Widow Spider (Latrodectus mactans)

The Black Widow Spider, scientifically known as Latrodectus mactans, is one of the most recognized and feared spiders in North America due to its distinctive appearance and potent venom. Here are some important facts about this species:

Potent Venom: The venom of the Black Widow Spider is extremely potent, containing neurotoxins that can cause severe pain, muscle cramps, and other systemic symptoms in humans. While rarely fatal due to the availability of antivenom, bites can be particularly dangerous for children, the elderly, and those with weakened immune systems.

Iconic Appearance: The Black Widow is best known for its shiny black color and the red hourglass marking on the underside of its abdomen. This distinct pattern serves as a warning to predators and humans alike.

Web Structure: Black Widow Spiders create irregular, tangled webs usually in dark, undisturbed areas close to the ground. They use these webs to capture prey, which mainly consists of insects and occasionally small vertebrates.

Behavior: These spiders are generally reclusive and not aggressive, tending to bite only in self-defense when disturbed or threatened. Most human bites occur when an unsuspecting person reaches into a dark area where a spider is hiding.

Habitat and Distribution: Found throughout the United States, particularly in the southern and western states, Black Widows prefer quiet, sheltered locations such as woodpiles, garages, basements, and under rocks or debris.

4. Brown Recluse Spider (Loxosceles reclusa)

Brown Recluse Spider (Loxosceles reclusa)

The Brown Recluse Spider, scientifically known as Loxosceles reclusa, is a spider known for its potent venom and tendency to dwell in undisturbed areas. Here are some key details about this species:

Necrotic Venom: The venom of the Brown Recluse Spider is highly toxic and can cause severe skin lesions and systemic symptoms. The bite typically leads to necrosis, where the affected tissue dies, often resulting in a painful ulcer that can take weeks or even months to heal.

Subtle Appearance: The Brown Recluse is typically light to medium brown, but can vary in color. It is identifiable by the violin-shaped marking on its back, with the neck of the violin pointing toward the rear of the spider. However, this marking is not always pronounced, making identification challenging.

Non-Aggressive Behavior: Despite its dangerous bite, the Brown Recluse is not aggressive and usually bites only when pressed against human skin or disturbed. Bites often occur when a person unknowingly touches or wears clothing or shoes where a spider has hidden.

Preferred Habitats: This spider prefers dry, warm, and dark environments, such as closets, attics, basements, and behind furniture. It is often found in cardboard boxes, among papers, and in seldom-disturbed areas.

Geographical Distribution: The Brown Recluse is primarily found in the central and southern United States. It is a resilient spider that can survive for months without food or water, making it adept at inhabiting human homes and structures.

5. Redback Spider (Latrodectus hasseltii)

Redback Spider (Latrodectus hasseltii)

The Redback Spider, scientifically known as Latrodectus hasseltii, is a venomous spider closely related to the Black Widow and is particularly prevalent in Australia. Here are some important aspects of this species:

Powerful Venom: The Redback Spider's venom is neurotoxic, similar to that of the Black Widow. It can cause significant pain, sweating, muscle weakness, and nausea in humans. Severe cases may require medical intervention, but fatalities are rare thanks to the availability of antivenom.

Distinctive Markings: The Redback Spider is easily recognizable by its glossy black body and the prominent red or sometimes orange stripe on the upper side of its abdomen. Some individuals may also have additional white markings.

Web Construction: Redback Spiders create tangled, irregular webs in sheltered locations close to the ground. These webs are used to trap a variety of prey, including insects and occasionally small vertebrates like lizards.

Behavior and Interaction: The Redback is known for its cannibalistic mating behavior, where the smaller male is often consumed by the female during or after mating. Despite their venomous bite, Redbacks are not aggressive and typically bite humans only when disturbed or threatened.

Habitat and Distribution: While most commonly found in Australia, Redback Spiders have also been spotted in Southeast Asia, New Zealand, and parts of the Middle East. In Australia, they prefer urban areas and are often found in garden sheds, under ledges, and in other quiet, undisturbed spots.

6. Goliath Birdeater (Theraphosa blondi)

Goliath Birdeater (Theraphosa blondi)

The Goliath Birdeater, scientifically known as Theraphosa blondi, is renowned for being one of the largest spiders in the world by mass and size. Here are some key facts about this impressive species:

Immense Size: The Goliath Birdeater can reach up to 12 inches (30 cm) in leg span and weigh over 6 ounces (170 grams). Its body can be as large as a small dinner plate, making it a truly formidable sight.

Diet and Hunting: Despite its name, the Goliath Birdeater rarely eats birds. Its diet primarily consists of insects, worms, and other small invertebrates. It is also known to occasionally prey on small mammals, amphibians, and reptiles.

Defensive Mechanisms: When threatened, the Goliath Birdeater can release hairs from its abdomen that are irritating to the skin and eyes of predators and humans. These urticating hairs are a key defense mechanism. The spider also produces a hissing sound by rubbing its legs together, which can be heard up to 15 feet away.

Habitat: Native to the rainforests of South America, particularly in northern Brazil, Venezuela, Guyana, and Suriname, the Goliath Birdeater prefers humid and dark environments. It lives in deep burrows which it either digs or occupies after other animals.

Interaction with Humans: While the Goliath Birdeater's venom is not lethal to humans, a bite can be painful due to the size of its fangs, which can be up to 1 inch (2.5 cm) long. Generally, this spider is not aggressive toward humans unless provoked.

7. Mouse Spider (Missulena)

Mouse Spider (Missulena)

The Mouse Spider, scientifically known as Missulena, is a genus of spiders that has several species found primarily in Australia. Here are some important details about these intriguing arachnids:

Potent Venom: Mouse Spiders have venom similar in composition to that of the Sydney Funnel-Web Spider, making it highly toxic. The venom can cause severe pain and systemic symptoms, but bites are rare and antivenom for funnel-web spider bites is also effective against mouse spider bites.

Distinct Appearance: Mouse Spiders are robust and medium-sized, with females typically larger than males. They have a glossy appearance with colors ranging from black to deep blue or even red for the head and thorax. Some species have bright red or orange jaw bases.

Burrowing Habit: Like funnel-web spiders, Mouse Spiders live in burrows, often with a silk-lined tunnel and a trapdoor made of soil and vegetation. These burrows can be quite deep and are typically found in open ground areas.

Behavior: Despite their potent venom, Mouse Spiders are not aggressive and tend to retreat rather than bite. Most human encounters occur when the spiders are out searching for mates or accidentally disturbed.

Geographical Distribution: Primarily found in Australia, the distribution of Mouse Spiders covers various habitats, from forests to arid regions. They are solitary creatures and are not commonly found in urban settings but may wander into such areas.

I’d give a 10 star review if I could! We had a great experience with Critter Stop. Everyone I dealt was friendly, professional, and reassuring. Phillip was very helpful and knowledgeable about the work he was doing. He walked me around the entire house to make sure I saw and understood the services he provided. He was also really nice and answered all my questions — he is exactly the type of person that should be interacting with customers.I love the fact that they will come back for up to 1 year after installation if any problems occur — this shows me they stand behind their work.The owner was great too, he personally came to my house and walked me through their offering. I recommend critter stop to anyone and everyone!

Critter Stop is a fantastic business! Everyone involved is extremely professional and very easy to communicate with. Chisam, the owner, did a great job of explaining the process to get the squirrels out of my attic during the initial free estimate. The exclusion crew who did all of the initial work was fabulous. The crew consisted of Phillip, Nick and Corey who arrived promptly when they said they would. They are happy, positive employees. Everyone is very polite and patient in explaining their work and answering questions. They came back several times to check the traps and finish it off with the fogging. Lester was very good about following up to schedule each trap check with me, and the office staff who took care of the billing was very efficient. Critter Stop is a well run company with honest, trustworthy employees! Thank you to all of you who worked hard to make my attic critter free and for the peace of mind that you guarantee your work. Great to know I can call them if for some reason a squirrel figures out a way to get back in!
