Hi all - I've got builders here doing a bathroom makeover for me at the moment although they're not on site for another few days. They left the soil pipe to the toilet totally uncapped when they took the toilet off so I taped my own plastic bag over it to stop smelly drafts coming out. I've gone into the bathroom (building site) today and the bag is full of living flies. I'm partly thinking this is normal as the pipe hasn't been flushed in around 3 months and the soil stack has a vent on the top, so flies are likely to come in and have a fun holiday in there. But I'm also partly concerned that it's indicative of some form of problematic infestation.
Thoughts appreciated!
