There are several dedicated tick removal tools on the outdoor market. When a tick attaches itself to a host, a very elaborate anchoring proboscis is buried in tissue.The tick then engorges on blood before dropping off to lay eggs and die. Ticks carry several diseases, most well known in the U.S. being lymne disease. Animals can become so infested they develop 'tick fever' or anemia so severe death may follow. Permanent mutilation of ears can be oserved in many free range horses. The best way to remove ticks is slow removal including the proboscis. This will result in a small wound with the removal of anchored flesh. This actually helps in letting blood flow and a followup of clean water or antiseptic to irrigate and cleanse the wound. Oils and other suffocates are a waste of time.
