Arachnid expert Norman Larsen says it's important to move both the nest and then spider when you encounter them in your home.
The rain spider, also known as huntsman spider, is one of the biggest non-tarantula spiders in the world.
Larsen shared his insights on safely relocating a rain spider nest after a Capetonian sought out advice.
Although they are harmless, Larsen says the spiders can be pretty aggressive when they are on the nest.
The best way to remove them is to use a plastic container, he explains.
While the spider is on the nest, it's quite aggressive. But once it leaves, it's totally placid.— Norman Larsen, arachnologist at Iziko South African Natural History Museum
The nests have normally got about 40 to 400 spiderlings in a nest.— Norman Larsen, arachnologist at Iziko South African Natural History Museum
