Apparently even Phnom Penh can become dangerous :-) as loads of insects can be found, from which the ants are probably the most harmless ones apart from those, who leave some badly itching wounds.
In addition there are some small nasty spiders, which can cause some serious infections.
But nothing beats an attack by a swarm of big bees at Hornet size, what might even become lethal depending on the amount of bites.
This bee didn't feel well after the entire tribe had been burnt by a brave landlord and his fearless daughter.
Before this highly aggressive swarm was raiding flats and kitchens, where their bites did produce large round wounds, that did not heal even after months.
