Hot can i cure my sewer/drain flies problem? help?

Question

they come up in all the sinks.

Answer 1

I work at Outback Steakhouse and anytime we have problems with flies or fruit flies a lady comes out and pours some stuff down all our drains and literally minutes later you can't FIND a fly anywhere.  Ask a plumber or pest control place if you can buy some.  Don't let them come check it or they'll charge you an arm and a leg!

Good Luck!

Answer 2

Pour bleach down your drain.

Answer 3

if you have flies coming out of your  frain you have a broken pipe or a dry trap somewhere . you need to repar the problem , if flies can get through so can sewer gases

Answer 4

pour baking soda and vinegar down your draines and tub and plunge out add hot water after that, it works!
