I was trying to fix my rubbish chute about 2 hours ago because the chute frame was loose. Having bought some epoxy material, I thought I was equipped to deal with the task ahead.
After some careful analysis and probing around the chute with a screwdriver, I realised that the silicon sealing around the whole frame needed to be peeled off so that I could seal the chute frame properly against the concrete wall. As I started to peel the silicon seal off, I saw that had taken on more than I originally intended.

Evidence of cockroach infestation...
The lower part of the rubbish chute where I peeled off the silicon seal seemed to have some black mould growing out of it. Kicking the rubbish chute door resulted in a rain of small little pellets that I now am quite sure, is cockroach eggs. So basically the chute frame has been harbouring a huge cockroach nest!!!!
I have since called some sanitary guy who will be here at 3pm tomorrow to change the whole chute door. I think i’ll keep an all night vigil fumigating the chute area every hour so that any mother cockroach that crawls out of the nest dies.
