Re: length of time between feedings
If you don't want to use bleach, distilled vinegar is a reasonable alternative. Also be aware that "corn syrup" is NOT the same thing as HFCS -high fructose corn syrup. If you are buying Karo Corn Syrup thinking it is useful for feeding bees, it is not a good choice. For liquid feeds, either make sugar syrup, or buy prepared HFCS, but plain HFCS is generally not available in grocery stores.
