I'm curious if there has ever been a study to see if allowing bees to build there own comb will reduce CCD versus using foundation or old comb? I know there are many ideas as to what is causing CCD but it seems like, from what I have heard and read, a lot of beekeepers whom's bee colonies are just disappearing are using old comb which is built on foundation. I have never read about a beekeeper whom is allowing the bees to build their own comb talk about losing bees from CCD. All the natural comb studies that I have read focus on reduced mite counts and a few other things. I wonder if all the chemicals we have been using are building up in the "old comb" which is the major reason for CCD? I would like to hear what people have to say on this whom are allowing the bees to build there own comb versus using foundation or old comb. Thanks in advance for your ideas.
