There is a company that specializes in deer deterrent, can't think of there name at the moment. Fencing is the only long term solution I know of.
If you're trying to reduce ticks, don't bother spraying lawns because tick habitat is shady, brush and tall grasses.
BS. wherever deer go so go ticks. We don't have pets but neighbors do. We keep yard (well mowed and clean) sprayed because we get ticks from the lawn
