Update: Moth Ball Bomb!
It’s almost 15 days to my drain flies extermination project. I’ve not seen any drain flies for the past couple of days. The numbers have dropped significantly in just 7 days. I also ran out of moth balls. I went to NTUC and found this massive ginormous tennis ball sized moth ball for only $0.85!! The best part about it is that I don’t have to keep refilling the moth balls everyday!
Friday will mark the 15th day, which should be the end of their life cycle. If everything goes well, I shouldn’t see these drain flies anymore. But as a precautionary, I’m just leaving my massive moth ball there till it sublimates completely.
