There are many species of large spiders in Thailand, including tarantulas, fortunately you’re not very likely to meet one of those. But unfortunately for you arachnophobes there is a rather large specimen who occasionally likes to take shelter indoors, especially during Thailand’s rainy season. Chances are you’ve already met the Huntsman spider, you may seen him scurry across you’re kitchen counter, he’s probably the one that scared the life out of you when you reached in the cupboard only to witness him run for cover. No need to worry though, there are far more dangerous bugs in Thailand than the Huntsman spider.
The Huntsman is actually quite harmless, they are very fast movers but their turn of speed is used to catch their prey or avoid larger predators, including you. The only time they are likely to be aggressive is if they are cornered or protecting a nest of young. Huntsman spiders can grow very large, one strain found in Laos is actually the largest spider in the world, it has a span of 25 – 30 centimeters. Huntsman spiders commonly found in Thailand are big enough to cover the palm of your hand.
The Huntsman spider is common throughout Thailand, it’s natural habitat is woodlands and forests, they do often venture indoors though. Although they are not likely to bite, the bite is venomous but not considered dangerous to healthy human beings. There is always the danger of allergenic reaction or infection though, especially for babies, children and elderly people.
Huntsman spiders can live for 2 years, they do not build a web, instead they hunt and forage for food which usually consists of insects and invertebrates. If you are prepared to tolerate them in your house they could prove to be an efficient pest controller.
