The safest way would probably be to get an oral flea/tick medication and put it in some food, then leave the food for him. You'll probably have to go through a vet, because it is my understanding that most/all of those are prescription only(?).
If you had a trap cage you could also attempt to catch him and then spray him with Frontline spray - though that would be more traumatic for both of you.
If you have any kind of relationship with the dog, you could try to put a Seresto collar on him, but only if you're sure he won't bite.
