The abandoned shopping mall in Bangkok, Thailand hides an incredible secret hard to guess. In 1997 the shopping mall was forced to close due to building infringements and later in 1999 a fire destroyed the roof and allowed rainwater to slowly overwhelm it. But with the fire and flood there was a mosquito problem created and the inhabitants of the area found the best way to overdue the problem. They brought freshwater tilapia fish in order to eat the insects and to rid themselves of the pests.
