The amount of flies my traps catch is really variable and depends heavily on temperature and what attractant(s) I am using. On a warm day it can catch anywhere from ten to twenty flies within a few hours, but, like I said, it really varies. I also check the traps frequently and remove the flies as quickly as I can before they die. It also helps that I put the traps on my back porch, where the garbage cans are located. There are always lots of flies buzzing around out there, but I have noticed a significant drop in the number of flies I see since the temps have dropped into the upper 50's (Fahrenheit). For example, I only caught one fly all day today.I've tried to use fly traps with very little success. How many does your trap catch per day?
If you can design a good trap it will work beautifully, but if your method already works great you might as well just stick with that. I just like the advantage of the traps doing all the work for me. And I also have a dog that defecates all over the backyard, and I too was catching them off the feces for a while, lol. I'm glad I don't need to do that anymore.
