PROCEDURE
Ticks are often found in the dense creases of the skin, so it is important to feel (palpate) these areas for any abnormal bumps. Examine the head, under their jaw, nose and nostrils first, carefully feeling along any creases where the hair may hide ticks.
Then inspect the outside and inside of their ears using gentle palpation to feel for abnormal bumps. Move to under their forelock and mane. Then inspect each leg beginning with their "armpit" and moving down to the coronet band. Examine the belly region including the udder or scrotum area. Finally examine the tail, dock and anal area.
If you discover ticks on your horse, you should not simply squeeze and pull them off. Using forceps or tweezers, grasp the tick by their head, where it enters the skin. Pull gently and firmly, in attempt to remove the entire tick, including their head. Gently blot the infestation site with a mild antiseptic. Watch the site for swelling, heat or inflammation that may result if infection sets in.
TIPS FOR SAFETY AND SUCCESS
There are many tall tales about how to best remove ticks, most of which are untrue and unwise. Do not crush, twist or apply oils or ointments to a tick. Do not hold a lit or hot matchstick or cigarette to their heads (a technique that may frighten your horse), which may make some ticks dig in further or release more infected saliva.
Proper disposal of ticks ensures that they do not return. Some recommend disposing of them in a small jar of alcohol, although placing them in a sealed trash bag is also fine.
If you suspect that your horse has Lyme disease, talk to your vet about saving these ticks for testing.
