    I read somewhere that over heating of hives could be a problem, that can be solved by putting a screen along the bottom of the hive, which would allow better air circulation, reduction of moisture buildup, and the mites that fall off the bees would fall through the screen.

    I tried it and was met with my bees swarming and leaving the hive en masse about a month later. It occurred to me that perhaps I went about it all wrong. I didn't put anything below the screen to block off the light. Since hives are mostly dark inside, whether in trees or boxes, I am thinking this was an error.

    It seems to me, if you block off the light, you also block off the ventilation you are trying to achieve. How would one construct a hive with a screen that blocks off the light, or should I ditch the idea and get rid of the screen altogether? G

    I live in Florida and all I use are screened bottom boards. I never had a problem with my bees absconding. When was the last time you checked your mite count?

    I hadn't checked it, because the bees which previously had been gentle, now were pissed off every time I looked in the hive. I have only had them for a few months, they were living in the wall of my house unknown to me, so I moved them into a hive and fed them in hopes they would survive (this was in december) they built a bunch of comb and had a lot of brood, so I cut back on the syruip, thinking they were doing well enough.

    I didn't see any mites on the comb the last time I looked, so I have no good answer for you. They were very active - then the next time I checked, they had bailed.

    I live in Los Angeles which gets toasty in the summer which is why I thought to try the screened hive.

    I think you did the right thing adding a screened bottom board. With that being said I doubt that was the reason they left.

    There are many reports of packages absconding with screened bottom boards. I tried them once, didn't like them and went back to solid boards. Never have regretted it. I've never had a hive abscond. Bees also abscond when loaded with mites. You will never see them on the comb, you have to do a sugar shake or an alcohol wash [my preference and much more accurate]. That's the only way to know what the mite population is.
