true, but fogging not proven yet. so you can still have a good 20 years IF it does cause cancer. but as for dengue fever (DHF)... start writing your will.
having lived next to a jungle, dengue is a serious threat in tropical countries. you dont want to see a dengue victim. for now, fogging is the only way for a large area. it will kill airbource mosquitoes and also their eggs. there are others in the pipeline to control mosquitoes like zapping them using electric field after luring them with odour or co2. (dont ask, i dont know if the man-made odour is approved by WHO). the device is small-ish but needs a lot to cover an area.
i understand your concern. check with your property
management when is their fogging schedule and take precaution to close all your doors and windows (and cover the fish tank). it is best not let the kids play outside until the fogging is cleared.
fogging is insecticide. if you really want to know more, you will have to ask what is the exact chemical they are using. there are different chemicals they can use for fogging. i think the property management is also protecting themselves. if any of the residents got bitten by an aedes mosquitoes, got dengue fever and die, it doesnt look good on them!
