Singapore is home to almost one hundred different species of spiders. The nation possesses a diverse range of biomes which provide different opportunities to arachnids.
Thankfully, some of the largest, most venomous, and intricately colored spiders will not be found in urban areas and instead live in densely forested regions. Property owners will still be likely to encounter other arachnids that can pose a threat to inhabitants and visitors to a location.
Spiders are not insects because they feature eight legs instead of six and have two body segments instead of three. The majority of spiders have eight eyes and all cannot hear. Instead, they have special hairs on their legs which detect movement in the environment around them.
Spiders are a form of arthropod characterized by their jointed legs, symmetrical bodies, and thick exoskeleton made of a material called chitin. Many people are scared of the appearance of spiders because of their unusual anatomy and how many possess fangs or pincers that deliver painful bites.
Almost all of these arachnids are venomous and will secrete digestive enzymes to break down their prey. None of the spiders in Singapore are known to have lethal bites and there have been few incidences of individuals being hospitalized.
3 Common Spiders in Singapore
Urban areas are frequently sprayed to keep the spider and other pest populations low. Properties with gardens or that are near protected areas are more likely to suffer from infestations, but the larger spiders are unlikely to invade. Some of the most commonly seen spiders around homes and businesses in Singapore are the Kidney Garden Spider, the Wolf Spider, and the Domestic Huntsman Spider.
Kidney Garden Spider
The Kidney Garden Spider lives in gardens and low bushes but can enter a property in search of food and other resources. Females can range in size from 6-9 mm. while males are 3-5 mm. This pest has a thick, round abdomen which is primarily white with black or dark brown markings. They are easy to identify because they have a dark, kidney-bean shaped mark on their backs.
Wolf Spiders can be anywhere between 10 and 35 mm. large and range in color from a dark yellow to tan to dark brown. These pests are primarily hunters and do not often build webs. Instead, they will search for prey and attack. Wolf Spiders possess three rows of eyes and have claws at the end of their legs to aid in their hunting. These are one of the most common invaders and will bite people and animals if they feel threatened.
Domestic Huntsman Spider
The Domestic Huntsman Spider have bodies which grow to be 3 cm. long with legs that are twice that size. They are a muddy brown with black around their faces. The females have a long horizontal white stripe across the front of their heads while the males have a pair of dark brown patches on the back. The Domestic Huntsman is a nocturnal creature and primarily feeds on cockroaches. If found on a property, they can indicate that there is another lurking pest problem.
Signs of a Spider Infestation and Prevention
Spiders will venture inside a property in search of food, to stay warm during cooler days, or to find a mate. One of the biggest warnings of an infestation is finding spider webs in the corner of rooms, which is a sign that the pest is making itself at home.
Besides this signal, there are very few signs of when spiders have entered a property. Most people will not realize there is an infestation until they see the pest themselves. Individuals need to be careful when dealing with spiders. Because they can venture inside during mating season, a person might not realize they have a problem until the young spiders have already left their mother’s egg sac and are roaming around.
One of the best ways to prevent an infestation is to keep the property clean. Spiders are attracted to areas which have other pests such as flies, cockroaches, and beetles. These pests are attracted to habitats with food, so a person can prevent spiders by making their home undesirable to other pests.
Cracks around doorframes windows, and in walls should be sealed to ensure spiders do not have a way in. Finally, since many types of spiders live in gardens and vegetation, it’s important to keep plants away from the house. People should make sure there is space between their gardens, shrubs, and compost piles and their homes or businesses so spiders have a harder time transitioning from the vegetation to the building.
