I am looking for help with keeping flies at bay while cooking on my BGE...spring is starting to show its face here in N.E.Ga. and the flies are the worst I have ever encountered...EVER....did a pork butt yesterday and I must have killed over 50 flies that got into the house yesterday and residuals today...we keep a neat and clean and tidy home and always clean up after each meal...with no crumbs, sauces, dirty dishes and pots and pans sitting in the sink or anything of the sort...this has become disgusting.....HELP! and thanks!
