Dengue is a serious health threat in Singapore. Fogging (1) is pretty common.
Now, the Singapore government says fogging should be used judiciously, not routinely. But, that doesn't seem to be the case. Many condos will fog once a week, year-round. Supposedly all operations must be submitted in the an "E-fogging Submission System", but as far as I can tell, there's no visibility into this.
Singapore has also recently declared a "climate change emergency", and I'd consider biodiversity, at the very least, a part of that.
My point is that: if the Singapore Government is unable or unwilling to manage this with a sense of urgency (or "emergency"), then I'm not generally hopeful.
