South Africa has many types of spiders, and while some may look scary, most are completely harmless. A few, however, can be risky, so it’s important to know which ones to watch out for. Understanding Common House Spiders in SA not only helps you feel at ease but also keeps your home safe. With a little knowledge, you can learn to tell the difference between harmless visitors and the ones that need extra caution.
Most Common House Spiders Are Harmless
Many of the spiders you find in your home are actually helpful. They eat flies, mosquitoes, and other pests, making them useful in keeping unwanted insects under control. Here are some of the harmless spiders you may see:
- Daddy Long Legs – These thin-legged spiders often hang in corners or under furniture. They are harmless to humans and great at catching small insects.
- Common Rain Spider – This large, brown spider looks scary but is not dangerous. It prefers to live in gardens and sometimes finds its way inside during rainy seasons.
- Pantropical Jumping Spider – This small spider jumps instead of spinning webs. It has good eyesight and is curious, but it does not bite humans.
These spiders are not a threat to you or your family. If you see one in your home, it’s likely just looking for a meal.

Few Species Are Medically Significant
Although most spiders are harmless, some species can be dangerous. These spiders have venom that can cause serious reactions in humans. Here are the two most concerning spiders in South Africa:
- Black Widow (Button Spider) – This spider is black with a red marking on its belly. Its bite can cause muscle pain, sweating, and difficulty breathing. If bitten, seek medical help immediately.
- Violin Spider – This brown spider has a violin-shaped marking on its back. Its bite can lead to skin damage and infection. Medical attention is necessary for serious bites.
These spiders are not aggressive and will only bite if they feel threatened. Avoid handling them, and be cautious when moving objects where they might be hiding, such as old boxes or woodpiles.

Identification is Key for Safety
Being able to tell the difference between harmless and venomous spiders is important. Here are some tips to help you identify them:
- Harmless spiders usually have thinner legs and move slowly.
- Venomous spiders like the Black Widow have bright markings and round bodies.
- Jumping spiders are small and move quickly with short bursts of jumps.
- Large brown spiders with thick legs are often garden spiders and not a danger to people.
If you are unsure about a spider, take a photo and compare it with online identification guides. You can also ask an expert at Spider Conservation SA for advice.
Habitat Management Reduces Encounters
Most spiders like quiet, dark places where they won’t be disturbed. By keeping your home clean and removing clutter, you can reduce the number of spiders inside. Here are some simple ways to prevent spiders from settling in your home:
- Seal small gaps around windows and doors.
- Keep storage areas tidy and avoid stacking items against walls.
- Shake out clothing, shoes, and blankets before using them, especially if they’ve been stored for a while.
- Regularly sweep corners and remove old spider webs.
In the garden, keep woodpiles away from the house, and avoid leaving outdoor lights on at night, as they attract insects, which in turn attract spiders.
