Identification, control & when to remove them safely
There are over 800 species of spiders found in Singapore, however, most of them live in the jungles and forested areas of Singapore. Spiders found in Singapore include 583 unique species from confirmed sightings.
Only a small fraction of Singapore spiders live in urban homes. Most jungle spiders never enter human buildings. This is important because it means your home spider problem is manageable.
Very successful in urban areas. Spin thin, tangled webs in corners, under sinks, garages, attics. Adult female: 6 to 7mm, male: 5mm. Long, skinny legs up to 30 times body length. Lives 1-3 years.
Wolf Spiders can be anywhere between 10 and 35 mm. large and range in colour from a dark yellow to tan to dark brown. Active hunters. Don’t build webs. These are one of the most common invaders and will bite people and animals if they feel threatened.
Adult female: 5/16″; male: 1/4″. Brown to grey color. Builds silken sacs instead of webs. One of the most poisonous spider species that can be found indoors. Nocturnal hunters.
Females can range in size from 6-9 mm. while males are 3-5 mm. Thick, round abdomen. White with black markings. They have a dark, kidney-bean shaped mark on their backs. Lives in gardens, enters homes for food.
Don’t build webs. Hunt by leaping onto prey. They hunt by leaping several centimeters onto their prey, grabbing them, and injecting venom by bite. Small, colorful. Great for pest control. Low bite risk.
Members of this family generally build spiral wheel-shaped webs that sometimes appear yellowish. Build very large webs. Their webs are among the biggest among the spiders, some reaching several metres wide, and have been observed to be strong enough to trap small birds. Rarely bite humans.
Most household spiders aren’t infestations. But these signs mean spider population is high:
Look out for spider egg sacs, which are white in colour and round in shape, attached to surfaces or spider webs. More than 3-4 sacs indicates high population.
Webs in every room, not just corners. Multiple webs on single wall. Sign of high spider population seeking shelter.
Tiny spiders on walls, windowsills. Recently hatched spiders looking for food. Indicates breeding activity.
Seeing spiders daily despite cleaning. Multiple sightings in short time period. Points to established colony.
Most house spiders should be left alone. But control them if:
In these cases, professional removal is safer than DIY attempts. Hiring pest control professionals helps not only to treat active spider infestations but also to identify and remove the reasons behind the infestation.
Cracks around doorframes windows, and in walls should be sealed to ensure spiders do not have a way in. Focus on gaps around doors and window frames.
Since many types of spiders live in gardens and vegetation, it’s important to keep plants away from the house. Maintain distance between gardens and building exterior.
A person can prevent spiders by making their home undesirable to other pests. Control flies, cockroaches, and ants. Spiders will leave without food source.
One of the best ways to prevent an infestation is to keep the property clean. Regular vacuuming removes webs and egg sacs before they multiply.
Remove unnecessary items. Spiders hide in boxes, papers, and stored items. Keeping your things organised will ensure that there is less clutter for spiders to build their nests and breed.
Well-ventilated spaces are less attractive to spiders. You can also keep the place well ventilated and free from moisture and water that attracts not just spiders but most pests.
Most spiders that live in the urban areas are not poisonous, however, you can find some poisonous species in the jungle areas of Singapore. House spiders are harmless to humans. Don’t confuse venom (which spiders have) with poison (which they don’t produce for humans).
No. Spiders are beneficial. They control pest insect populations. Killing them removes natural pest control. Safe removal and relocation is the best approach.
Spiders feast on other insects like flies, ants and woodlice. Different species prefer different prey. Most common house spiders eat the pests you want to eliminate anyway.
Varies by species. Daddy longlegs females live 3 years. Males often die after mating (1 year). Most house spiders live 1-2 years. Golden orb-weavers live longer.
Call professionals if spider population is causing significant distress, if you’re seeing hundreds of spiderlings, or if you have Yellow Sac Spiders indoors. Otherwise, simple vacuuming handles most situations.
Most household spiders help you control pests. But if spider populations are causing concern or discomfort, professional safe removal is available. We relocate spiders humanely.
