I have this phorid fly problem in my flat in this old house that’s been converted into 3 flats. Phorid flies are to be found in my kitchen, lounge and hallway since September. I’ve also seen them downstairs next to the door of the flat there (the flat below me).
This pest controller guy visited my flat yesterday and said he reckoned it’s most likely the overflow pipe in the kitchen sink all gunked up. But he also suggested the problem might originate from the flat underneath. Or that cleaning the pipes might not work and fumigation might be necessary. But that initially a plumber would come round and change the waste trap section or whatever underneath the kitchen sink.
OK, the property management working for the landlord just sent me an email where she states: " The pest controller has advised me that the flies have been living and breeding in the waste trap section of your sink due to the debris that have accumulated in there". She goes on to say that the cleanliness of the drains is my responsibility and that I (the tenant) will be expected to pay the invoice for any works undertaken. She suggested I might sort the problem out myself by putting bleach down the sink and wastepipe. Well, I’ve put huge amounts of bleach down the sinks and overflow thingies (is that a waste pipe?) in the past 3 months and that didn’t do anything!
The question I would like to ask is whether tenants are obliged to have to occasionally dissemble the pipes below the sink and clean them? If so, then so be it. However, I’m a bit concerned that since it hasn’t been definitely established that it is these pipes, it could be money down the drain (so to speak) if in fact the problem resides elsewhere. (The pest controller guy said to me that he reckoned waste trap section was the most likely source, not that it definitely was).
A bit more info. My flat suffers from damp problems that the property management and landlord are aware of and have been sent photos of, but haven’t done anything about. Does this change anything?
Any advice would be much appreciated.
