Residents of Pine Grove condominium in Bukit Timah have been dealing with unwelcome visits by uninvited visitors.

Stomper Sook Hui shared with Stomp that monkeys have been entering apartments and leaving a trail of destruction.

"Pine Grove is under attack by monkeys again," she said.

"For the unfortunate residents who suffer visits from monkeys (sometimes more than 20), their entire home will be in a mess with smashed eggs, overturned or broken cookie jars and bowls and remnants of half-eaten fruits strewn everywhere."

She shared a video with Stomp of around 10 monkeys from her window, with some of them entering and exiting her neighbours' units. Some of them appeared to be nibbling on fruit.

Considering the situation, the Stomper shared that most residents do their best to keep their doors and windows closed at all times, or install narrow grilles to keep the primates out.

"However, this is not always possible," Sook Hui said.

"The Singapore weather is getting hotter by the day and not all units can afford to install full-house air-conditioning nor redo all their grilles."
