Placing them outside and then firing up the grill and hoping that they won't be around won't work.
Change the bait at least 1 time per month, more often in humid or rainy conditions. The EZ Strike bait station has a lid that opens from the front with a small key. Inside there are 2 removable trays that can be filled with bait. Fairly simply process.
For flies outside around food, we alway took our scraps and placed them some ways away from us. That way the flies would have something that attracted them away from us. No easy fixes for this.
Hope this helps.
