When I have traveled in the past I liked to try and fish in remote areas, for this reason I always took an Aspivenom in my medical kit, it’s a small pump for extracting venom should you be unlucky enough to be bitten or stung, it is only first aid though and you should seek medical attention as soon as possible, I have not seen them here but I have not really looked either, a search on the web may find a supplier

I don’t really have any idea about the types of snakes and insects here but I would have though scorpions a more likely threat
