In another light, regardless of there presence, it could also mean there's an abundance of food (rodents) and enough water with in their territory to keep the fox den going. Example - there's an area near me that is over loaded with rattle snakes during the warmest of summer months. To me this says there is more then enough natural feed to allow the population to exist.
Rodents of the sort would be the problem with a hive, not the fox unless she/he decides to try and sit on top of the hive. I see them in trees a lot but I'd imagine they don't get stung to often sitting on a branch.
