I read this on Mr. Bush's site (If you have clean wax (no chemicals in the hive) your queens usually last about three years. If you don't have clean wax, your queens usually only last a few months.)
Does this mean from pesticides from outside sources or from chemicals to treat hive pest ect.?
Sorry if this sounds like a dumb question but trying to learn all we can to do what is best for the bees.
