Hi Luis, Here is a video with tips to get rid of them.
If they're outdoor flies, then use this disposable fly trap. Just don't put it near your patio. It does stink but extremely effective! https://www.homedepot.com/p/RESCUE-Disposable-Fly-Trap-FTD-DB12/100083352
Hi Luis. Mix a half-cup Apple Cedar Vinegar, One teaspoon Molasses, a quarter-cup of sugar, and one cup of water. Mix well until sugar is dissolved. You can use this indoors and outdoors. Save empty water bottles and pour a little bit of this solution in them. Hang the bottles. The flies will find it themselves.
Blue can Lysol, we spray our patio table and that does the trick for us
