Flies in the bathroom

Louise86b

Hi. Looking for help/advice
For a long time we've had tiny little flies in the bathroom.
( They are not drain flies)
Finally realised our shower cubicle seal was allowing water out and under the tiled floor into the wood
The flies are coming from the wet wood.
The seal has now been fixed but the flies persist!
We can't rip up the floor/shower.
How can I get rid of these pesky flies, there's so many every day!
Will they eventually stop as the floor dries out?
The shower must have been leaking for months so I'm assuming the floor is pretty wet, although downstairs neighbor has not had the water penetrate his celling so it can't be totally drenched.
Any help or advice would be appreciated!

I’d be more worried about timber rot than flies, if joists are damp and aren’t the modern treated sort you may end up with dry rot.

 I had dry rot in a flat once, it’s a right pain as your joists are someone else’s ceiling(luckily it was fixed without damage, it’s one thing to damage your own ceiling worse to damage someone else’s)

if you aren’t a very competent diyer and need pro assistance rot dry rot in particular gets very expensive very quickly, get that floor and sub floor bone  dry ASAP

The floor isn't going to dry out very quickly now that you've sealed the shower plinth.  You probably want to leave that off and let some air get down there; a dehumidifier will probably help.  If it's just one plank that's wet then you probably don't need to go removing tiles.  The flies will stop when it dies out.

We had the same problem when we moved into our current house, a slow leak that never came through the ceiling, but saturated a floorboard and it couldn't dry out.  I could have put my finger through it by the time I'd spotted it (which was when the tiles sank half an inch and I couldn't really miss it).
