Do you want to know more about these Jamaican arachnids? Here are the nine most commonly seen spiders in Jamaica.

Brown Recluse Spider

Latin Name: Loxosceles Reclusa

Also known as the violin spider, brown recluse spiders are the most dangerous spiders in Jamaica. They have been given this safe-sounding nickname due to the coloring on the brown body. The violin shape does vary greatly from each individual, so other key features are also used for identification, such as:

  • Dark brown body and lighter colored legs
  • Six eyes in pairs (unlike a typical eight-eyed arachnid)
  • Fine hairs across body and legs
  • The body is no larger than 1/2 inch in width

This dangerous spider can be found in quiet and typically undisturbed places across Jamaica. So be cautious if you are clearing out the attic or garage, moving dusty boxes from dark places, or shifting rock piles. You may just uncover a residing brown recluse spider.

Brown recluse spiders pack a powerful bite. The venom is 15 times more toxic than a cobra, containing a hemotoxic venom can that can cause large painful wounds and potentially even death if left untreated. In fact, this spider was responsible for a bride’s near-death experience while on her Jamaican honeymoon in 2017.

Widow Spiders

Jamaica has three variations of widow spiders: the black widow, the brown widow, and the red widow. All three are venomous spiders and some of the most dangerous animals in Jamaica.

Black Widow Spider

Latin Name: Latrodectus Mactans

One of the world’s most venomous spider species, the black widow spider is the most iconic and feared arachnid. These spiders are easily recognizable with the red hourglass on the back of the black shiny body; the size ranges from 3mm to 10mm. Black widows can be found in rock piles and dark crevices.

A black widow bite causes nausea, muscle pain, and breathing difficulties. If bitten, medical treatment is advisable and full recovery is possible. Medical treatment in Jamaica is limited, so do your best to avoid a bite from a black widow.

Brown Widow Spider

Latin Name: Lactrodectus Geometricus

Brown widow spiders are twice as venomous as the black widow variety and are commonly found across Jamaica. This is the most venomous spider in Jamaica. However, unlike the aggressive black widow, the brown widow spiders generally withdraw and hide from confrontation.

As the name suggests, these spiders are brownish in color and they have an orange hourglass on the underside. Brown widows pack a powerful neurotoxic venom that can cause death; 15 minutes after a bite, the victim will experience muscular pain throughout the body. This is then followed by muscle cramps, breathing difficulties, anxiety and disorientation, headaches, and seizures.

Red Widow Spider

Latin Name: Lactrodectus Bishopi

The last of the widow spiders in Jamaica, the red widow spider is extremely similar to the black widow species. The venom is of similar potency and has the same side effects. They are more of a reddish-brown and have a triangular hour-glass on the abdomen.

Red widow spiders will only bite humans if they feel threatened or are protecting the nest. This is the largest of the widow spiders, females typically measure between 1.5 – 2 inches across the body.

Banana Spider

Yes, that is right, banana spiders can be found among banana trees, mostly found on the leaves. Banana trees and banana spiders are common across Jamaica.

Females can grow up to 80mm in body length. The males are tiny in comparison, generally only reaching 0.5mm in body length. Typically, the banana spider stays outdoors, so you don’t need to worry about checking your Jamaican hotel room for these guys.

Banana spiders are poisonous and have peculiar side effects on humans if bitten. The venom attacks the nervous system causing salivation, irregular heartbeat, and prolonged painful erections in men.

Yellow sac spiders are poisonous and you could get bitten if this spider gets caught up in your clothes. This spider’s venom is cytotoxic which destroys and damages cell function throughout the body. While this venom can be painful, its effects on humans are not severe and will not lead to death.

They can be found in grass, on leaves, and under stones, but they do prefer to be indoors. So watch out for the silken tubes spun by these spiders in wardrobes and room corners. Sizes range from 0.12 inches to 0.6 inches.

Wolf spiders are found across the world, including the paradise island of Jamaica and even the Arctic Circle!

The black house spider is your classic looking spider – about 1 cm in length, thick dark brown legs, a solid charcoal-grey body, and some feature white indistinct markings on the abdomen. These spiders can be found in an assortment of places across Jamaica:

  • tree trunks, logs, and rock walls
  • buildings exteriors, in window frames and crevices

Latin Name: Sparassidae

Last but not least, we have the largest spider found in Jamaica – the huntsman spider. Some individuals reach a whopping 160mm in leg span. However, despite the scarily large size of these spiders, they are generally inoffensive to humans and stay out of the way. That being said, huntsman spiders are poisonous, though their bite is not fatal to humans.

Huntsman spiders eat a variety of insects, arthropods, small lizards, and frogs. The prey is not captured in a web like most spiders but is actively stalked and run-down with stealth and speed. These spiders are found Jamaica-wide and are usually on tree trunks, under banks, beneath stones, or on the walls of houses.

Identifying a huntsman is fairly straight forward. The body is large and the two back pairs of legs are shorter than the ones at the front. The legs fan out sideways enabling them to walk forwards and sideways often giving them a crab-like appearance, giving them a local nickname of the “crab spider”. Colors vary between brown, black, and grey.
