Reposting because the flies have emerged!
After the months and months of over 105F and no rain. We got 2", and flies. Flies are freakin everywhere! Thick swarms, so I had to do something.
I tried various recipes for traps and repellents. The Lavender worked a bit, but still my home was invaded. This one trap worked the best out of all that I tried.
1 quart jar, with lid
1/2 cup vinegar
1/2 cup sugar
Puncture some medium holes in the lid. Add the sugar and vinegar, then top with water. Screw on lid and place jar where the flies are a nuisance.
