Video footage shows adult and baby monkeys – which are normally fed by tourists – racing to grab chunks of corn to eat in Nakhon Ratchasima province on January 18.
The villagers could only watch from afar as the creatures ravaged their crops.
One of the farmers said he did not dare to stop the animals as they were too many and could become aggressive.
A gang of more than 100 monkeys raided a farm on Tuesday to steal food in Thailand after a lack of tourists due to Covid-19 cut off their food supply. Pictured: The monkeys run across a road, captured in video footage of the gang moving towards the farm
He said: ‘It would be impossible to stop all of them and dangerous, too. One monkey is enough to harm people if it wants too.
‘Imagine having to stop more than a hundred hungry monkeys. So we just let them eat the crops.’
As the farm is close to the national park, other animals such as elephants, cattle, and bulls, have raided the area before to search for food.
The monkey gang emerged from the Khao Phaeng Ma Non-Hunting Area and Khao Yai National Park where they lived.
Recorded from inside a car, the footage showed the driver slowly creeping up the dusty road as monkeys ran across in front the vehicle.
Panning to the right of the car, the person filming showed a number of other monkeys hiding among the foliage, before chasing after the rest of the gang.

Tourism has plummeted in Thailand, leaving the monkeys without a consistent source of food. In Q2 and Q3 of 2020, virtually no tourists arrived in Thailand, with the latest available figures from the Thai Ministry of Tourism showing just 3,065 tourists arrived from abroad in November
They used to be fed with snacks by tourists but due to the pandemic, there were fewer visitors to give them food.
Some of the animals have also taken over the road appearing to move to the next place while carrying their babies when they have finished eating corn.
The devastated farmers sought help from local government agencies so they can be compensated for the crops and prevent the incident from happening again.
The first quarter of 2020 saw tourist arrivals in Thailand drop to 6.7 million people, down from 10.7 million from the first quarter of the previous year, as the coronavirus pandemic began to sweep the globe and limit the number of people travelling.
In March 2020, just 800,000 came to Thailand, compared to 3.4 million in 2019, with the country closing its borders to tourists for the month of April.

In July last year, it was reported that the city of Lopburi, around 30 miles west of edge of Nakhon Ratchasima province, had been overrun by macaques.
Lopburi is home to some 8,400 macaques which were a major tourist draw before lockdown stopped visitors from coming. However, without food, they became a menace to the locals
Residents of Lopburi said that without tourists to feed the monkeys, they turned violent, attacking people and each-other in an increasingly desperate search for food
A lack of tourists and a consistent source of food led to the monkeys becoming aggressive, with as many as 8,400 overrunning the city and forcing locals to avoid going outside where possible.
Local vets were even forced to sterilise some the monkeys to try and keep their numbers down, with police admitting they were powerless to do anything.
Before the coronavirus, the monkeys drew tourists to the city, with many purchasing fruit from local businesses to feed the monkeys for a photo opportunity.
They also drew the Buddhist faithful, who believe feeding the animals to be a meritorious deed.
