Hey all... I own a bbq restaurant in south central TX. Our entire dining area is outdoors and every year when the Texas heat and humidity comes rolling in we experience a horrible fly situation. I know being outdoors flies will be natural and I can live with that... but that's not what I'm talking about. I'm talking about when I set down someone's food within seconds there are literally 10-15 flies swarming their table. It's ruining our reputation, sales are decreasing, and quite honestly it's embarrassing. I've tried everything we can think of. We keep the restaurant as clean as possible, spray down the gravel outdoors every morning with a bleach solution, wipe down the tables with bleach after every customer, and don't keep any trashcans in the dining area. I've gone through 2 different pest control companies now... each one tells me there's nothing that we are doing wrong but they can't seem to help the situation. I've tried hanging several of the plastic baggies with water and a few pennies in each, even tried having a basil plant on each table as I heard that would deter them. Nothing is working. I'm not sure if it's our location, being right on the outskirts of the downtown area and located next to a big open field but I need to improve this before it ruins us for good. Please please please feel free to share with me any tips or advice you might have. I know I will never solve the problem completely, but even marginally improving it would be a big help. In Houston a lot of people I know install misting systems on their patios for the mosquitos, I'm thinking maybe something like that would work for the flies but then I'm concerned adding more moisture to the air will make the problem worse. I appreciate your time for reading this and thank you in advance for your help.
