how to prevent ticks:
1. Use specially made tick repellants on your horse.
2. If you prefer to hand-pick ticks, wear gloves. To remove a tick, grasp it as close to its host's skin as possible using fingers or forceps. Don't squeeze. Apply slow, steady, upward pressure until the tick comes away intact. Drop detached ticks into a jar of soapy water, then dispose of tick-laden liquid by burying it or flushing it down the toilet.
I think no.3 is a clever way to keep ticks away.
3. Keep a flock of Guinea fowl or free-range chickens. Feathered barnyard marauders consider ticks the pinnacle of haute cuisine--and you can dine on their eggs!
