I've been having horrible trouble with flies these past few weeks. I've tried all kinds of things! I did apple jelly with a hint of soap, fruit juice with a drop of soap, vinegar and fruit juice with a drop of soap, soapy water, and yeast! I've been catching more yellow jackets, wasps, and honeybees than flies! Really more yellow jackets. I don't want to catch honeybees! I just bought some fly bait from the feed store, yet I haven't caught a single fly!! Does anyone have any suggestions for fly traps? Honestly I've killed more flies with the fly swatter than anything else!
