Dee,
I fear chemical contamination more so. Bees have been surviving nature's pressures successfully for millions of years, why should I fear nature and try to protect and keep my bees unprepared for nature.
Chemical drugs on the other hand, like are in use today are not things the bees find out in the wide open. We put them there. Even such things as formic acid which occur naturally in hives are never present even in the smallest fractions of the concentrations being implimented.
On the other hand, I do not use foundation, so I don't fear either in my hives really. Just pesticides used on crops and flowers around are my biggest concerns.
