Officials in central Prachuap Khiri Khan went to a three story property after complaints that the building was being used to attract swallows at night.
The swallows - a protected species - would go to the building and the owner would harvest their nests to make the expensive "bird's nest" soup craved by many Asians.
Neighbors had complained to the government watchdog Damrongtham about the noises at night used to attract the birds and the smell from polluted water that came from the building.
Yesterday morning Saengpratheep Khunathimaphan from Damrongtham led a group of military, police, environmentalists and animal experts to the property in Soi Ran "Big Phone".
A notice was left on the gate threatening further legal action.
The owner and the manager were nowhere to be found - they had apparently flown the nest.
A German man who lives next door told Banmuang that if the problem isn't sorted out within two months he will move elsewhere.
The German man said he is sick to death of the problems caused by the birds, which include noise at all hours and a foul smell.
He said that the birds shouldn't be allowed to nest in a building in a residential area.
