Had a LOT of these things in the bathroom lately and not sure what they are. There's normally a few in the morning but at around 8-9pm there can be 50+ of them, and they seem to appear out of nowhere.. I have put the plugs in and taped up overflows but they don't seem to be coming from there.
Have poured a fair few different drain cleaning/unblocking products down the plugs/drains with no success.
The one pictured is probs the size of a twenty pence piece all in and looks like a baby daddy long legs. They make a high pitch noise when they fly (wings I think). Anyone have any idea what it is and how to stop this happening? Getting sick of vacuuming/splatting them nou.
