Keep flies away by repairing your screens.
Examine windows and doors where flies may enter.

Screens and open doors are the main sources of entry to your house. Unlike other insects that need to eat through wood, crawl under your siding or burrow into your foundation, flies waltz right in as though they were invited guests.
Screen holes can be easily repaired with screen repair kits available at any hardware store.
Remember what your mother always told you – “Close the door!”
And never leave a fresh peach pie to cool on an open window sill. This action can only invite a great swarm of flies. Woe!
You have to admit, getting rid of flies in not rocket science. All it takes is a little determination and attention to detail. Good luck getting rid of flies.
