Hi Patrick,
I'm afraid I haven't a clue about the "sulfer" thing, but ticks don't present a problem for honeybees. I'll assume you're concerned about yourself getting a tick bite and I don't blame you as they carry some nasty stuff. I would say the best thing to do is mow or cut the grass/weeds/shrubs immediately around the hives. Ticks climb up low shrubs/tall grass and weeds and with outstretched forelegs grasp anything that brushes by (that's how they get on you). In addition I'd place pant legs in socks, wear light colored clothing (so you can see ticks more readily) and spray pant legs and sleeves with something like off. It's my understanding you won't get a disease if the tick isn't embedded in your skin for something like 24hr's. Hope this is helpful.
