probably, but the apiguard evaporates and goes down into the hive. a little more air space and it will be more efficient. you can make your own. i made a few for my hives and i'm no woodworker! ;)
.....The greatest changes occur in their country without their cooperation. They are not even aware of precisely what has taken place. They suspect it; they have heard of the event by chance. More than that, they are unconcerned with the fortunes of their village, the safety of their streets, the fate of their church and its vestry. They think that such things have nothing to do with them, that they belong to a powerful stranger called the government. They enjoy these goods as tenants, without a sense of ownership, and never give a thought to how they might be improved.....
