How do I get rid of flies?

HEre is a good post https://www.jcehrlich.com/flies/how-to-get-rid-of-flies/

There are fly traps on Amazon add water to activate the attractions rescue brand is the one I use, add water to the designated line, hang it up.

The best way is with prevention. You say they come in while you are eating? Do you have screens on your open doors and windows? Do you live in agricultural areas where there are many flies or is there something outside attracting them like uncovered trash cans etc? I am not trying to be unkind, it is just easiest to prevent such pests and it is good to check out a source of attraction and prevent them entering. Then fly traps work well once there are some inside, also fly paper and I hope this helps. Please do not be offended by my prevention questions, I am not insinuating anything. If I had flies, I would start there. We had a problem one year and it was from our neighbor never cleaning up after their dog. A little chat and that solved 90% of our problem.

Wipe down table and chairs with diluted peppermint extract. The flies won't land on it. Keep a cup of the solution with a sponge nearby to keep wiping.
